1 IBX Change Log version (2.0.3) tba, 24 Feb 2017 12:17:53 +0000
3 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 changes.
6 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 Bug could result in truncated multi-byte character set values.
9 3. Changes consequential on moving fbintf character set utility functions from
10 IFirebirdAPI to IAttachment.
12 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
14 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
15 include remote system name.
17 2. TIBExtract: No longer include comment header and COMMIT statement for empty
18 tables when data included in output.
20 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
21 and timing information to be written to stdout. This may be used to locate
22 performance bottlenecks.
24 4. SQLParser: only call "OnChanging" event handler when value is different.
26 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
28 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
29 that BindFields is called when the query is next activated. Avoids FieldName
30 not found error.
32 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
34 1. TIBEvents: Fix uninitialised variable that could result in lost events.
36 2. TIBExtract: Added support for FB3 "USAGE" privilege.
38 3. TIBExtract: data formatted as Charset set "octets" is now output using
39 hexadecimal notation.
41 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
42 using a simple XML format.
44 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
45 grants to these objects.
47 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
48 dependency problems restoring complex databases.
50 7. TIBXScript: This component has been restructured to allow for the processing of
51 embedded XML in INSERT statements and to support interactive sources in addition
52 to non-interactive data sources such as files.
54 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
56 9. TIBXScript: ISQL compatiable Set statements are now supported:
64 SET NAMES <character set>
66 10. IBVersion unit added to hold current IBX Version Number information.
68 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
69 and domain definitions.
71 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
72 fully supported.
74 13. TIBExtract: when a database dump includes data, the generator values are now also set.
76 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
78 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
80 See also doc/IBX4LazarusGuide.pdf for important information on
81 upgrading to IBX2.
83 1. Size property of TIBStringField is now the width in characters of the field
84 and not the byte length. This applies only to multi-byte character sets such
85 as UTF8. The original approach aligned with TStringField. However, the TStringField
86 code is not recognised as a bug and hence this change to align the behaviour.
87 The TStringField change is expected in fpc 3.2.0.
89 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
90 true (default) then Size property value saved in the lfm is ignored. Size is
91 always set from the dynamic information read from the database. It is unclear
92 why anyone would want to override this and set Size to false.
94 3. ibxscript: should now handle correctly a Case..End statement within a procedure
95 block.
97 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
98 exist when an attempt is made to connect to it (run time only) then an attempt
99 is made to create the database.
101 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
102 has been successfully created as a result of a call to CreateDatabase or when
103 creating a database after it was found not to exist.
105 6. DBControlGrid: a race condition could result in the wrong row image being
106 written to the cache. This has been avoided by a trip round the message
107 loop before rendering the row image.
109 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
110 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
111 known to risk corrupt rendering of row images when the control is first
112 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
113 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
115 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
116 a TDateEdit control located on an editor panel.
118 9. TIBExtract: brought up-to-date plus many bug fixes.
120 10. DBControlGrid: Removed memory leak when updating rows.
122 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
124 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
126 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
127 when target codepage is CP_NONE. This is a workaround for
130 2. DBLog option removed from TIBStatisticalService - not supported by server
131 since Firebird 1.5.
133 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
134 similar.
136 4. IBCodePage: updated mapping between codepages and character id.
138 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
139 Firebird. Character sets with a char width of two are not UTF16.
141 6. Strings received from the database are now always transliterated into UTF8
142 regardless of the database character set or connection character set. This
143 is for compatibility with the LCL.
145 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
147 1. IBBlob: Defer reading of blob until read method called. This avoids having to
148 read in an entire blob just to get the size of the blob. General performance
149 improvement when opening datasets containing blobs.
151 2. Clearing a Blob now sets the corresponding field's modified flag.
153 3. IBLookupCombo: When not performing auto-complete, original query sort order
154 is now used.
156 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
157 determined.
159 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
161 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
162 lazarus 1.6.0
164 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
165 compilation error.
167 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
169 1. No character set specified for connection: when a text blob is retrieved, the
170 character set is determined by looking up the native character set using then
171 Firebird API. Otherwise a text mode blob is assumed to have the same character
172 set as the connection.
174 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
175 for Login Dialog returing a change to the database path.
177 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
178 to be changed from that given in the TIBDatabase/TIBServer component and for the
179 entered value to be saved on a project specific basis (design time only).
181 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
182 column fieldname. If they are the same then it is acts as a look up for the KeyValue
183 Otherwise, it sets the column text to the selected ListField Value.
185 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
186 column width.
188 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
189 and a case insensitive search is requested.
191 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
192 or column ListSource.
194 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
195 unprepare) when closing and the text has not changed.
197 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
198 Less likely to cause a cursor re-use error on Windows.
200 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
201 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
203 11. TIBTreeView: Guard against nil destination on record changed
205 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
206 string type with the code page set to reflect the returned field encoding after
207 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
208 earlier versions.
210 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
211 will now result in transliteration to the code page specified for the Firebird driver
212 if the assigned string has a different code page. FPC 3.0.0 onwards only.
214 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
215 is ignored and the lc_ctype value, when the database is opened, is set to align with
216 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
217 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
218 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
219 the GETACP is used to determine the Windows code page.
221 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
222 name used as the lc_ctype when the database was opened. Only valid while the
223 Database is connected.
225 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
226 id that corresponds to the DefaultCharSetName.
228 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
230 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
231 path is given and database attach fails due to access permission issues on the
232 temp directory or security database, then the attach is retried with "localhost:"
233 prefixing the databasename. This should avoid problems when the database has to
234 be accessed by a local (e.g. classic) server and libfbembed is used.
236 2. Windows: revised search order for Firebird DLL:
237 i. The Firebird Embedded Server in the application Directory.
238 ii. If the FIREBIRD environment variable is set then the directory this
239 points to is searched for the FB Client DLL and then then underlying
240 "bin" directory.
241 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
242 is used to locate the Firebird installation directory and the underlying
243 "bin" directory is searched for the FB Client DLL.
244 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
245 are searched for the FB Client DLL.
246 v. The PATH Environment variable is used to search for the FB Client DLL.
247 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
249 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
250 See doc/readme.scriptengine and example applications.
252 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
253 simplify the use of the embedded firebird server on both Linux and Windows platforms.
254 See dpc/readme.localdatabase and example applications.
256 5. IBDynamicGrid: Reordering on column header click should now also work for
257 dynamic columns.
259 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
260 between incrementing/decrementing the lock count and signalling the event.
262 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
264 1.3.2 was never formally released and only made available as beta copies.
266 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
268 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
270 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
272 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
273 i.e. when it is a calculated field
275 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
276 This problem was due to a race condition between recalculating row heights and
277 determining which row was selected by the mouse click. The row height calculation
278 is now deferred by an extra trip round the message loop allowing the row to
279 be always calculated on the current grid layout rather than risking it being
280 calculated on the grid layout after the expanded row has been shrunk.
282 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
283 Windows.
285 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
286 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
287 to be determined at runtime. See doc/readme.charactersets.html.
289 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
290 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
292 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
293 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
294 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
296 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
297 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
298 implies no truncation.
300 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
302 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
303 (avoids "Not in Edit Mode" error).
305 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
307 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
308 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
310 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
312 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
314 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
316 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
318 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
320 1. OnCloseUp Event Handler added to TDBLookupProperties
322 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
323 problem with row size when exception is called.
325 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
327 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
328 in a TCustomComboBox and ignores return key if in a TCustomMemo
330 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
331 keyed in i.e. when autocomplete not performed
333 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
334 console mode applications with all LCL required functions (builtin dialogs and
335 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
336 not included in your project, IBX should compile and link with a console mode program.
337 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
338 console mode application or the IDE will automatically assume that your
339 application is GUI based. Instead, you should include the ibexpressconsolemode package.
341 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
342 to use the built in dialogs and cursor management. IBDialogs is
343 included by default if "ibexpress" is in your project source's "uses" clause.
344 This should be the case for all projects created through the IDE. This is why
345 you do not want to add the ibexpress package to console mode applications. The
346 ibexpressconsolemode package has been created to allow console mode programs
347 to avoid adding LCL dependencies when using IBX, while still having the
348 unit search paths set up correctly.
350 Existing users should check to ensure that the "ibexpress" unit is included in
351 each project's source file (*.lpr).
353 You may find that in order for the IDE to recognise that ibexpressconsolemode
354 exists, you have to first open the package in the IDE and then close it. This
355 adds it to the most recently accessed packages list. To make it permanently
356 available, add the package name to lazarus' file.
358 Thanks to Julio Jiménez for suggesting support of console mode.
360 7. SQL Parser can now accept quoted strings that include new lines
362 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
363 of text on start of edit. This is particularly useful when tabbing to a
364 column and then inserting text.
366 9. New Examples provided for IB Services and ISQLMonitor.
368 10. Fix error when writing to blob streams that recorded only the last buffer
369 write in the blob stream. In most cases, this did not cause a problem as the
370 IB Blob Stream is written in a single write. However, with the TDBImage, write
371 of a graphic type prefix was lost which caused a problem when the image could
372 not be automatically recognised.
374 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
375 already open" errors due to random numbers used for the cursor name being identical.
377 12. IBTable: corrected error that could result in an "Index out of bounds" error
378 when opening the table and the Primary Key is the last or only column in the
379 table. Thanks to Rick Hoover for the fix.
381 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
382 of "UTF-8", and update list of available database character sets. Existing
383 users should check the current lc_ctype setting in their applications.
385 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
387 1. Firebird Services: avoid List Index error when opening a service with an
388 empty Params property.
390 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
391 Link now set up in Loaded method - avoids occasional failure to apply
392 SQL markup on initial open.
394 3. "Employees" example performance improvements when scrolling.
396 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
397 TFrame. Force recaching of selected frame to avoid GTK race (results in a
398 random image cached).
400 5. DBControlGrid: Should now react to changes in panel height at run time.
402 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
403 even when further rows exist.
405 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
406 always be derived from panel height and setting this property can cause confusion.
407 Note for existing projects: to avoid a missing property error at run time,
408 each form using the DBControlGrid must be opened, updated and saved in the IDE
409 in order to remove the property value from the lfm.
412 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
414 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
415 call Prepare before setting parameter values.
417 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
419 3. Code tidyup and more robust handling of dsql information result vector.
421 4. Support for centralised handling of transaction status changes. TIBTransaction
422 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
423 and "AfterExecQuery". The first three are called after the same event is called
424 for an IBCustomDataSet descendent using the Transaction. The fourth is called
425 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
426 enable monitoring of transaction status changes for a given transaction to be
427 handled in a single place. For example, when a change to the dataset occurs
428 an indicator can be set that shows the user that in order to save changes,
429 the transaction should be committed. Rather than doing this per dataset, this
430 can now be done per transaction.
432 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
433 the dataset is scrolled. However, any changes to the current row are, by default,
434 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
435 have a new property "DataSetCloseAction" that adds automatic posting of changes
436 on dataset close. If this property is set to dcDiscardChanges (default) then the
437 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
438 then IBX will attempt to post any unsaved changes before the dataset is closed
439 (and after the BeforeClose event handler is called). The exception is when the
440 dataset is being closed as a result of a transaction rollback. In this case,
441 no action is taken and any unsaved changes are discarded. This avoids both
442 unnecessary overhead and the risk that a validation error may occur in the Post
443 raising an exception and thereby preventing a rollback.
445 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
446 In earlier versions, the Display Width was set to the maximum byte width rather than the character
447 width. Display Widths are now corrected by dividing by the max byte width per character.
448 For UTF8 character sets, the byte width is four and hence the Display Width will be
449 the byte width divided by 4. The byte width of each character set is determined
450 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
451 system table. (see also
453 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
455 8. IBLookupComboEditBox: List should now always be restored to full list when the
456 control loses focus. Default Key press default interval reduced to 200ms.
458 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
459 when dataset rows are less than visible rows.
461 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
462 does not exist or DataSet is empty. More responsive on dataset open. New event
463 OnRestorePosition. Column sort disabled if no header row.
465 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
466 while dataset state is dsInsert. Avoids posting errors.
468 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
469 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
471 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
473 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
474 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
475 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
476 always "posts" the current record regardless or whether or not it may be more appropriate
477 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
478 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
479 as the first action of the "Post" method and allows the handler to convert the Post
480 into a Cancel if that is the appropriate action on moving to a different row. This is
481 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
482 raised here, but it may still be more appropriate to validate a post and signal
483 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
485 15. On Unix derived systems, the Firebird library name can now be given as a colon
486 separated list. Each library name on the list is tried in turn, in left to right
487 order with the first found being used as the firebird library. By default, on Linux,
488 the library name list is ''. This can be
489 overidden by the FBLIB environment variable or the OnGetLibraryName function.
491 Note: when using the, if you prefix the database name with "localhost:"
492 then it will still attempt to access the database via the Firebird Server and will
493 require a username and password. If only the pathname is given, then the username
494 and password should be omitted and the unix file permissions are used to grant
495 access.
497 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
499 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
500 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
501 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
502 corresponds to a row of the linked DataSource. Any data aware control on the
503 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
505 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
506 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
507 takes place during database access. This may be useful when there are performance issues with
508 the change of cursor. Setting the property to false suppresses the change of cursor.
510 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
511 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
512 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
513 making all changes permanent immediately rather than when the transaction is explicitly
514 committed.
516 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
517 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

521 Development version only.
523 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
525 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
526 This is typically used during an "OnBeforeOpen" event handler to manipulate the
527 "Where" and "Having" clauses to implement user specified filters of arbitrary
528 complexity.
530 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
531 three new data aware controls dependent on IBX and which make use of the SQL Parser.
532 These are:
534 - TIBLookupComboEditBox
535 - TIBDynamicGrid
536 - TIBTreeview
538 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
539 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
540 to revise the available list and restrict it to items that are prefixed by the
541 typed text (either case sensitive or case insensitive). Autoinsert allows a
542 newly typed entry to be added to the list dataset and included in the available
543 list items.
545 TIBDynamicGrid is a TDBGrid descendent that provides for:
546 - automatic resizing of selected columns to fill the available row length
547 - automatic positioning and sizing of a "totals" control, typically at the
548 column footer, on a per column basis.
549 - DataSet resorting on header row click, sorting the dataset by the selected column.
550 A second click on the same header cell reversed the sort order.
551 - Support for a "Panel Editor". That is on clicking the indicator column, the row
552 is automatically expanded and a panel superimposed on it. The panel can have any
553 number of child controls, typically data aware controls with the same datasource
554 as the grid allowing for editing of additional fields and more complex editors.
555 - Reselection of the same row following resorting.
556 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
557 Its properties are specified on a per column basis and allows for one or more
558 columns to have their values selected from a list provided by a dataset.
559 Autocomplete and autoinsert are also available. The existing picklist editor
560 is unaffected by the extension.
562 TIBTreeView is a data aware TCustomTreeView.
564 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
565 zero scale will no longer return an error. An Int64 will be returned instead.
567 4. TIBTransaction now has events for Before and After Transaction End and a new function
568 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
570 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
571 repeated multiple times.
573 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
574 check used to get in the way of using Stored Procedures, and "Update or Insert"
575 statements.
577 7. Insert, Modify and Delete property Editors now support Query Generation from
578 Stored Procedures.
580 8. Three new examples illustrate the use of the new IB Controls
583 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
585 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
586 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
587 Gabor Boros for reporting this problem and for testing the improvements).
589 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
590 See readme.field+param.names in the doc folder.
592 3. IBX SQL Editors will now automatically add double quotes around column names when the database
593 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
595 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
597 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
598 actions.
600 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
601 thanks to Yuriy Kopnin for pointing this out).
603 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
605 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
606 for both fields and parameter setting.
608 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
609 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
611 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
612 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
614 11. TIBTable now has a property editor for "MasterFields"
616 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
617 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
619 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
620 of settings is unrecognised. Selecting this radio button has no effect on the settings.
623 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
625 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
627 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
629 1. In a TIBCustomDataset descendent, a generator now only sets the value when
630 it is null. This allows for alternative user defined setting of the generator
632 Many thanks to Julio Jiménez for this fix
634 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
635 and suggests that the user may have forgotten to install it.
637 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
639 1. Conditional compilation used to limit registration of TIntegerField to
640 Lazarus versions less than 1.1
642 2. When a database connection is created, character set is now by default set
643 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
644 1250 to 1254.
647 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
649 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
652 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
654 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
655 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
657 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
658 package is changed to do this (which it should do).
660 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
662 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
664 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
666 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
668 4. Property editors should now correctly resize.
670 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
671 (restored original functionality)
673 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
674 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
