1 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
2
3 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
4
5 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
6
7 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
8
9 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
10 i.e. when it is a calculated field
11
12 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
13 This problem was due to a race condition between recalculating row heights and
14 determining which row was selected by the mouse click. The row height calculation
15 is now deferred by an extra trip round the message loop allowing the row to
16 be always calculated on the current grid layout rather than risking it being
17 calculated on the grid layout after the expanded row has been shrunk.
18
19 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
20 Windows.
21
22 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
23 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
24 to be determined at runtime.
25
26 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
27 TWideStringField. This field type is used with the character size reported by Firebird is two.
28
29 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
30 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
31 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField).
32
33 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
34 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
35 implies no truncation.
36
37 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
38
39 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
40 (avoids "Not in Edit Mode" error).
41
42 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
43
44 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
45 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
46
47 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
48
49 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
50
51 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
52
53 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
54
55 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
56
57 1. OnCloseUp Event Handler added to TDBLookupProperties
58
59 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
60 problem with row size when exception is called.
61
62 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
63
64 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
65 in a TCustomComboBox and ignores return key if in a TCustomMemo
66
67 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
68 keyed in i.e. when autocomplete not performed
69
70 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
71 console mode applications with all LCL required functions (builtin dialogs and
72 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
73 not included in your project, IBX should compile and link with a console mode program.
74 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
75 console mode application or the IDE will automatically assume that your
76 application is GUI based. Instead, you should include the ibexpressconsolemode package.
77
78 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
79 to use the built in dialogs and cursor management. IBDialogs is
80 included by default if "ibexpress" is in your project source's "uses" clause.
81 This should be the case for all projects created through the IDE. This is why
82 you do not want to add the ibexpress package to console mode applications. The
83 ibexpressconsolemode package has been created to allow console mode programs
84 to avoid adding LCL dependencies when using IBX, while still having the
85 unit search paths set up correctly.
86
87 Existing users should check to ensure that the "ibexpress" unit is included in
88 each project's source file (*.lpr).
89
90 You may find that in order for the IDE to recognise that ibexpressconsolemode
91 exists, you have to first open the package in the IDE and then close it. This
92 adds it to the most recently accessed packages list. To make it permanently
93 available, add the package name to lazarus' staticpackages.inc file.
94
95 Thanks to Julio Jiménez for suggesting support of console mode.
96
97 7. SQL Parser can now accept quoted strings that include new lines
98
99 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
100 of text on start of edit. This is particularly useful when tabbing to a
101 column and then inserting text.
102
103 9. New Examples provided for IB Services and ISQLMonitor.
104
105 10. Fix error when writing to blob streams that recorded only the last buffer
106 write in the blob stream. In most cases, this did not cause a problem as the
107 IB Blob Stream is written in a single write. However, with the TDBImage, write
108 of a graphic type prefix was lost which caused a problem when the image could
109 not be automatically recognised.
110
111 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
112 already open" errors due to random numbers used for the cursor name being identical.
113
114 12. IBTable: corrected error that could result in an "Index out of bounds" error
115 when opening the table and the Primary Key is the last or only column in the
116 table. Thanks to Rick Hoover for the fix.
117
118 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
119 of "UTF-8", and update list of available database character sets. Existing
120 users should check the current lc_ctype setting in their applications.
121
122 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
123
124 1. Firebird Services: avoid List Index error when opening a service with an
125 empty Params property.
126
127 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
128 Link now set up in Loaded method - avoids occasional failure to apply
129 SQL markup on initial open.
130
131 3. "Employees" example performance improvements when scrolling.
132
133 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
134 TFrame. Force recaching of selected frame to avoid GTK race (results in a
135 random image cached).
136
137 5. DBControlGrid: Should now react to changes in panel height at run time.
138
139 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
140 even when further rows exist.
141
142 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
143 always be derived from panel height and setting this property can cause confusion.
144 Note for existing projects: to avoid a missing property error at run time,
145 each form using the DBControlGrid must be opened, updated and saved in the IDE
146 in order to remove the property value from the lfm.
147
148
149 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
150
151 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
152 call Prepare before setting parameter values.
153
154 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
155
156 3. Code tidyup and more robust handling of dsql information result vector.
157
158 4. Support for centralised handling of transaction status changes. TIBTransaction
159 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
160 and "AfterExecQuery". The first three are called after the same event is called
161 for an IBCustomDataSet descendent using the Transaction. The fourth is called
162 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
163 enable monitoring of transaction status changes for a given transaction to be
164 handled in a single place. For example, when a change to the dataset occurs
165 an indicator can be set that shows the user that in order to save changes,
166 the transaction should be committed. Rather than doing this per dataset, this
167 can now be done per transaction.
168
169 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
170 the dataset is scrolled. However, any changes to the current row are, by default,
171 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
172 have a new property "DataSetCloseAction" that adds automatic posting of changes
173 on dataset close. If this property is set to dcDiscardChanges (default) then the
174 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
175 then IBX will attempt to post any unsaved changes before the dataset is closed
176 (and after the BeforeClose event handler is called). The exception is when the
177 dataset is being closed as a result of a transaction rollback. In this case,
178 no action is taken and any unsaved changes are discarded. This avoids both
179 unnecessary overhead and the risk that a validation error may occur in the Post
180 raising an exception and thereby preventing a rollback.
181
182 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
183 In earlier versions, the Display Width was set to the maximum byte width rather than the character
184 width. Display Widths are now corrected by dividing by the max byte width per character.
185 For UTF8 character sets, the byte width is four and hence the Display Width will be
186 the byte width divided by 4. The byte width of each character set is determined
187 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
188 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
189
190 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
191
192 8. IBLookupComboEditBox: List should now always be restored to full list when the
193 control loses focus. Default Key press default interval reduced to 200ms.
194
195 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
196 when dataset rows are less than visible rows.
197
198 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
199 does not exist or DataSet is empty. More responsive on dataset open. New event
200 OnRestorePosition. Column sort disabled if no header row.
201
202 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
203 while dataset state is dsInsert. Avoids posting errors.
204
205 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
206 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
207
208 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
209
210 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
211 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
212 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
213 always "posts" the current record regardless or whether or not it may be more appropriate
214 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
215 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
216 as the first action of the "Post" method and allows the handler to convert the Post
217 into a Cancel if that is the appropriate action on moving to a different row. This is
218 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
219 raised here, but it may still be more appropriate to validate a post and signal
220 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
221
222 15. On Unix derived systems, the Firebird library name can now be given as a colon
223 separated list. Each library name on the list is tried in turn, in left to right
224 order with the first found being used as the firebird library. By default, on Linux,
225 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
226 overidden by the FBLIB environment variable or the OnGetLibraryName function.
227
228 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
229 then it will still attempt to access the database via the Firebird Server and will
230 require a username and password. If only the pathname is given, then the username
231 and password should be omitted and the unix file permissions are used to grant
232 access.
233
234 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
235
236 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
237 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
238 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
239 corresponds to a row of the linked DataSource. Any data aware control on the
240 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
241
242 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
243 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
244 takes place during database access. This may be useful when there are performance issues with
245 the change of cursor. Setting the property to false suppresses the change of cursor.
246
247 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
248 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
249 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
250 making all changes permanent immediately rather than when the transaction is explicitly
251 committed.
252
253 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
254 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
255
256 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
257
258 Development version only.
259
260 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
261
262 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
263 This is typically used during an "OnBeforeOpen" event handler to manipulate the
264 "Where" and "Having" clauses to implement user specified filters of arbitrary
265 complexity.
266
267 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
268 three new data aware controls dependent on IBX and which make use of the SQL Parser.
269 These are:
270
271 - TIBLookupComboEditBox
272 - TIBDynamicGrid
273 - TIBTreeview
274
275 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
276 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
277 to revise the available list and restrict it to items that are prefixed by the
278 typed text (either case sensitive or case insensitive). Autoinsert allows a
279 newly typed entry to be added to the list dataset and included in the available
280 list items.
281
282 TIBDynamicGrid is a TDBGrid descendent that provides for:
283 - automatic resizing of selected columns to fill the available row length
284 - automatic positioning and sizing of a "totals" control, typically at the
285 column footer, on a per column basis.
286 - DataSet resorting on header row click, sorting the dataset by the selected column.
287 A second click on the same header cell reversed the sort order.
288 - Support for a "Panel Editor". That is on clicking the indicator column, the row
289 is automatically expanded and a panel superimposed on it. The panel can have any
290 number of child controls, typically data aware controls with the same datasource
291 as the grid allowing for editing of additional fields and more complex editors.
292 - Reselection of the same row following resorting.
293 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
294 Its properties are specified on a per column basis and allows for one or more
295 columns to have their values selected from a list provided by a dataset.
296 Autocomplete and autoinsert are also available. The existing picklist editor
297 is unaffected by the extension.
298
299 TIBTreeView is a data aware TCustomTreeView.
300
301 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
302 zero scale will no longer return an error. An Int64 will be returned instead.
303
304 4. TIBTransaction now has events for Before and After Transaction End and a new function
305 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
306
307 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
308 repeated multiple times.
309
310 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
311 check used to get in the way of using Stored Procedures, and "Update or Insert"
312 statements.
313
314 7. Insert, Modify and Delete property Editors now support Query Generation from
315 Stored Procedures.
316
317 8. Three new examples illustrate the use of the new IB Controls
318
319
320 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
321
322 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
323 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
324 Gabor Boros for reporting this problem and for testing the improvements).
325
326 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
327 See readme.field+param.names in the doc folder.
328
329 3. IBX SQL Editors will now automatically add double quotes around column names when the database
330 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
331
332 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
333
334 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
335 actions.
336
337 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
338 thanks to Yuriy Kopnin for pointing this out).
339
340 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
341
342 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
343 for both fields and parameter setting.
344
345 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
346 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
347
348 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
349 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
350
351 11. TIBTable now has a property editor for "MasterFields"
352
353 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
354 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
355
356 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
357 of settings is unrecognised. Selecting this radio button has no effect on the settings.
358
359
360 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
361
362 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
363
364 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
365
366 1. In a TIBCustomDataset descendent, a generator now only sets the value when
367 it is null. This allows for alternative user defined setting of the generator
368
369 Many thanks to Julio Jiménez for this fix
370
371 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
372 and suggests that the user may have forgotten to install it.
373
374 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
375
376 1. Conditional compilation used to limit registration of TIntegerField to
377 Lazarus versions less than 1.1
378
379 2. When a database connection is created, character set is now by default set
380 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
381 1250 to 1254.
382
383
384 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
385
386 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
387
388
389 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
390
391 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
392 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
393
394 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
395 package is changed to do this (which it should do).
396
397 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
398
399 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
400
401 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
402
403 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
404
405 4. Property editors should now correctly resize.
406
407 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
408 (restored original functionality)
409
410 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
411 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
