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.

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 <    correspondes to a row of the linked DataSource. Any data aware control on the
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 surpressed and no cursor change
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.

251     committed.
252  
253 < 4. Experiental support for the Firebird 3 SQL_BOOLEAN type has been added while still
254 <   using the legacy Firebird API.

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
# Line 38 | Line 275 | IBX Change Log  version
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 insenstive). Autoinsert allows a
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.
