10 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if

12 >
13 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
14 >     keyed in i.e. when autocomplete not performed
15 >
16 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
17 >     console mode applications with all LCL required functions (builtin dialogs and
18 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
19 >     not included in your project, IBX should compile and link with a console mode program.
20 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
21 >     console mode application or the IDE will automatically assume that your
22 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
23 >
24 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
25 >     to use the built in dialogs and cursor management. IBDialogs is
26 >     included by default if "ibexpress" is in your project source's "uses" clause.
27 >     This should be the case for all projects created through the IDE. This is why
28 >     you do not want to add the ibexpress package to console mode applications. The
29 >     ibexpressconsolemode package has been created to allow console mode programs
30 >     to avoid adding LCL dependencies when using IBX, while still having the
31 >     unit search paths set up correctly.
32 >
33 >     Existing users should check to ensure that the "ibexpress" unit is included in
34 >     each project's source file (*.lpr).
35 >
36 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
37 >     exists, you have to first open the package in the IDE and then close it. This
38 >     adds it to the most recently accessed packages list. To make it permanently
39 >     available, add the package name to lazarus' staticpackages.inc file.
40 >
41 >         Thanks to Julio Jiménez for suggesting support of console mode.
42 >
43 > 7.   SQL Parser can now accept quoted strings that include new lines
44 >
45 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
46 >     of text on start of edit. This is particularly useful when tabbing to a
47 >     column and then inserting text.
48 >
49 > 9.   New Examples provided for IB Services and ISQLMonitor.
50 >
51 > 10. Fix error when writing to blob streams that recorded only the last buffer
52 >    write in the blob stream. In most cases, this did not cause a problem as the
53 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
54 >    of a graphic type prefix was lost which caused a problem when the image could
55 >        not be automatically recognised.
56 >
57 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
58 >    already open" errors due to random numbers used for the cursor name being identical.
59 >
60 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
61 >    when opening the table and the Primary Key is the last or only column in the
62 >    table. Thanks to Rick Hoover for the fix.
63 >
64 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
65 >    of "UTF-8", and update list of available database character sets. Existing
66 >    users should check the current lc_ctype setting in their applications.
67 >
68 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
69 >
70 > 1.  Firebird Services: avoid List Index error when opening a service with an
71 >    empty Params property.
72 >
73 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
74 >    Link now set up in Loaded method - avoids occasional failure to apply
75 >    SQL markup on initial open.
76 >
77 > 3.  "Employees" example performance improvements when scrolling.
78 >
79 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
80 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
81 >    random image cached).
82 >
83 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
84 >
85 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
86 >    even when further rows exist.
87 >
88 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
89 >    always be derived from panel height and setting this property can cause confusion.
90 >    Note for existing projects: to avoid a missing property error at run time,
91 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
92 >    in order to remove the property value from the lfm.
93 >
94 >
95 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
96 >
97 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
98 >    call Prepare before setting parameter values.
99 >
100 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
101 >
102 > 3.  Code tidyup and more robust handling of dsql information result vector.
103 >
104 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
105 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
106 >    and "AfterExecQuery". The first three are called after the same event is called
107 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
108 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
109 >    enable monitoring of transaction status changes for a given transaction to be
110 >    handled in a single place. For example, when a change to the dataset occurs
111 >    an indicator can be set that shows the user that in order to save changes,
112 >    the transaction should be committed.  Rather than doing this per dataset, this
113 >    can now be done per transaction.
114 >
115 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
116 >    the dataset is scrolled. However, any changes to the current row are, by default,
117 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
118 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
119 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
120 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
121 >    then IBX will attempt to post any unsaved changes before the dataset is closed
122 >    (and after the BeforeClose event handler is called). The exception is when the
123 >    dataset is being closed as a result of a transaction rollback. In this case,
124 >    no action is taken and any unsaved  changes are discarded. This avoids both
125 >    unnecessary overhead and the risk that a validation error may occur in the Post
126 >    raising an exception and thereby preventing a rollback.
127 >
128 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
129 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
130 >    width. Display Widths are now corrected by dividing by the max byte width per character.
131 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
132 >    the byte width divided by 4. The byte width of each character set is determined
133 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
134 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
135 >
136 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
137 >
138 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
139 >    control loses focus. Default Key press default interval reduced to 200ms.
140 >
141 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
142 >    when dataset rows are less than visible rows.
143 >
144 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
145 >    does not exist or DataSet is empty. More responsive on dataset open. New event
146 >    OnRestorePosition. Column sort disabled if no header row.
147 >
148 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
149 >    while dataset state is dsInsert. Avoids posting errors.
150 >
151 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
152 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
153 >
154 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
155 >
156 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
157 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
158 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
159 >    always "posts" the current record regardless or whether or not it may be more appropriate
160 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
161 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
162 >    as the first action of the "Post" method and allows the handler to convert the Post
163 >    into a Cancel if that is the appropriate action on moving to a different row. This is
164 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
165 >    raised here, but it may still be more appropriate to validate a post and signal
166 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
167 >
168 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
169 >    separated list. Each library name on the list is tried in turn, in left to right
170 >    order with the first found being used as the firebird library. By default, on Linux,
171 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
172 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
173 >
174 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
175 >    then it will still attempt to access the database via the Firebird Server and will
176 >    require a username and password. If only the pathname is given, then the username
177 >    and password should be omitted and the unix file permissions are used to grant
178 >    access.

181  
182   1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
183      rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
184      that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
185 <    correspondes to a row of the linked DataSource. Any data aware control on the
185 >    corresponds to a row of the linked DataSource. Any data aware control on the
186      replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
187  
188   2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.

208   1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
209     This is typically used during an "OnBeforeOpen" event handler to manipulate the
