2 >
3 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
4 >   read in an entire blob just to get the size of the blob. General performance
5 >   improvement when opening datasets containing blobs.
6 >
7 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
8 >
9 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
10 >   is now used.
11 >
12 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
13 >   determined.
14 >
15 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
16 >
17 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
18 >   lazarus 1.6.0
19 >
20 > 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
21 >   compilation error.
22 >
23 > IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
24 >
25 > 1. No character set specified for connection: when a text blob is retrieved, the
26 >  character set is determined by looking up the native character set using then
27 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
28 >  set as the connection.
29 >
30 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
31 >   for Login Dialog returing a change to the database path.
32 >
33 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
34 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
35 >   entered value to be saved on a project specific basis (design time only).
36 >
37 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
38 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
39 >   Otherwise, it sets the column text to the selected ListField Value.
40 >
41 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
42 >   column width.
43 >
44 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
45 >   and a case insensitive search is requested.
46 >
47 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
48 >   or column ListSource.
49 >
50 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
51 >   unprepare) when closing and the text has not changed.
52 >
53 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
54 >   Less likely to cause a cursor re-use error on Windows.
55 >
56 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
57 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
58 >
59 > 11. TIBTreeView: Guard against nil destination on record changed
60 >
61 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
62 >    string type with the code page set to reflect the returned field encoding after
63 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
64 >    earlier versions.
65 >
66 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
67 >    will now result in transliteration to the code page specified for the Firebird driver
68 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
69 >
70 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
71 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
72 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
73 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
74 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
75 >    the GETACP is used to determine the Windows code page.
76 >
77 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
78 >    name used as the lc_ctype when the database was opened. Only valid while the
79 >    Database is connected.
80 >
81 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
82 >    id that corresponds to the DefaultCharSetName.
83 >
84 > IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
85 >
86 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
87 >   path is given and database attach fails due to access permission issues on the
88 >   temp directory or security database, then the attach is retried with "localhost:"
89 >   prefixing the databasename. This should avoid problems when the database has to
90 >   be accessed by a local (e.g. classic) server and libfbembed is used.
91 >
92 > 2. Windows: revised search order for Firebird DLL:
93 >     i.   The Firebird Embedded Server in the application Directory.
94 >     ii.  If the FIREBIRD environment variable is set then the directory this
95 >          points to is searched for the FB Client DLL and then then underlying
96 >          "bin" directory.
97 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
98 >          is used to locate the Firebird installation directory and the underlying
99 >          "bin" directory is searched for the FB Client DLL.
100 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
101 >          are searched for the FB Client DLL.
102 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
103 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
104 >
105 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
106 >   See doc/readme.scriptengine and example applications.
107 >
108 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
109 >   simplify the use of the embedded firebird server on both Linux and Windows platforms.
110 >   See dpc/readme.localdatabase and example applications.
111 >
112 > 5. IBDynamicGrid: Reordering on column header click should now also work for
113 >   dynamic columns.
114 >
115 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
116 >   between incrementing/decrementing the lock count and signalling the event.
117 >
118 > IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
119 >
120 > 1.3.2 was never formally released and only made available as beta copies.
121 >
122 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
123 >
124 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
125 >
126 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
127 >
128 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
129 >   i.e. when it is a calculated field
130 >
131 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
132 >   This problem was due to a race condition between recalculating row heights and
133 >   determining which row was selected by the mouse click. The row height calculation
134 >   is now deferred by an extra trip round the message loop allowing the row to
135 >   be always calculated on the current grid layout rather than risking it being
136 >   calculated on the grid layout after the expanded row has been shrunk.
137 >
138 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
139 >   Windows.
140 >
141 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
142 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
143 >   to be determined at runtime. See doc/readme.charactersets.html.
144 >
145 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
146 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
147 >
148 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
149 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
150 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
151 >
152 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
153 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
154 >   implies no truncation.
155 >
156 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
157 >
158 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
159 >   (avoids "Not in Edit Mode" error).
160 >
161 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
162 >
163 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
164 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
165 >
166 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
167 >
168 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
169 >
170 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
171 >
172 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
173 >
174 > IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
175 >
176 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
177 >
178 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
179 >     problem with row size when exception is called.
180 >
181 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
182 >
183 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
184 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
185 >
186 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
187 >     keyed in i.e. when autocomplete not performed
188 >
189 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
190 >     console mode applications with all LCL required functions (builtin dialogs and
191 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
192 >     not included in your project, IBX should compile and link with a console mode program.
193 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
194 >     console mode application or the IDE will automatically assume that your
195 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
196 >
197 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
198 >     to use the built in dialogs and cursor management. IBDialogs is
199 >     included by default if "ibexpress" is in your project source's "uses" clause.
200 >     This should be the case for all projects created through the IDE. This is why
201 >     you do not want to add the ibexpress package to console mode applications. The
202 >     ibexpressconsolemode package has been created to allow console mode programs
203 >     to avoid adding LCL dependencies when using IBX, while still having the
204 >     unit search paths set up correctly.
205 >
206 >     Existing users should check to ensure that the "ibexpress" unit is included in
207 >     each project's source file (*.lpr).
208 >
209 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
210 >     exists, you have to first open the package in the IDE and then close it. This
211 >     adds it to the most recently accessed packages list. To make it permanently
212 >     available, add the package name to lazarus' staticpackages.inc file.
213 >
214 >         Thanks to Julio JimĂ©nez for suggesting support of console mode.
215 >
216 > 7.   SQL Parser can now accept quoted strings that include new lines
217 >
218 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
219 >     of text on start of edit. This is particularly useful when tabbing to a
220 >     column and then inserting text.
221 >
222 > 9.   New Examples provided for IB Services and ISQLMonitor.
223 >
224 > 10. Fix error when writing to blob streams that recorded only the last buffer
225 >    write in the blob stream. In most cases, this did not cause a problem as the
226 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
227 >    of a graphic type prefix was lost which caused a problem when the image could
228 >        not be automatically recognised.
229 >
230 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
231 >    already open" errors due to random numbers used for the cursor name being identical.
232 >
233 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
234 >    when opening the table and the Primary Key is the last or only column in the
235 >    table. Thanks to Rick Hoover for the fix.
236 >
237 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
238 >    of "UTF-8", and update list of available database character sets. Existing
239 >    users should check the current lc_ctype setting in their applications.

354  
355   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
356      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
# Line 132 | Line 372 | IBX Change Log  version
372   4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
373     using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
