1. An internal select SQL Parser is now available for TIBCustomDataset descendents. |
| 4 |
+ |
This is typically used during an "OnBeforeOpen" event handler to manipulate the |
| 5 |
+ |
"Where" and "Having" clauses to implement user specified filters of arbitrary |
| 6 |
+ |
complexity. |
| 7 |
+ |
|
| 8 |
+ |
2. A new Component Palette entry "Firebird Data Controls" is now available. This has |
| 9 |
+ |
three new data aware controls dependent on IBX and which make use of the SQL Parser. |
| 10 |
+ |
These are: |
| 11 |
+ |
|
| 12 |
+ |
- TIBLookupComboEditBox |
| 13 |
+ |
- TIBDynamicGrid |
| 14 |
+ |
- TIBTreeview |
| 15 |
+ |
|
| 16 |
+ |
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" |
| 17 |
+ |
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation |
| 18 |
+ |
to revise the available list and restrict it to items that are prefixed by the |
| 19 |
+ |
typed text (either case sensitive or case insenstive). Autoinsert allows a |
| 20 |
+ |
newly typed entry to be added to the list dataset and included in the available |
| 21 |
+ |
list items. |
| 22 |
+ |
|
| 23 |
+ |
TIBDynamicGrid is a TDBGrid descendent that provides for: |
| 24 |
+ |
- automatic resizing of selected columns to fill the available row length |
| 25 |
+ |
- automatic positioning and sizing of a "totals" control, typically at the |
| 26 |
+ |
column footer, on a per column basis. |
| 27 |
+ |
- DataSet resorting on header row click, sorting the dataset by the selected column. |
| 28 |
+ |
A second click on the same header cell reversed the sort order. |
| 29 |
+ |
- Support for a "Panel Editor". That is on clicking the indicator column, the row |
| 30 |
+ |
is automatically expanded and a panel superimposed on it. The panel can have any |
| 31 |
+ |
number of child controls, typically data aware controls with the same datasource |
| 32 |
+ |
as the grid allowing for editing of additional fields and more complex editors. |
| 33 |
+ |
- Reselection of the same row following resorting. |
| 34 |
+ |
- A new cell editor that provides the same functionality as TIBLookupComboEditBox. |
| 35 |
+ |
Its properties are specified on a per column basis and allows for one or more |
| 36 |
+ |
columns to have their values selected from a list provided by a dataset. |
| 37 |
+ |
Autocomplete and autoinsert are also available. The existing picklist editor |
| 38 |
+ |
is unaffected by the extension. |
| 39 |
+ |
|
| 40 |
+ |
TIBTreeView is a data aware TCustomTreeView. |
| 41 |
+ |
|
| 42 |
+ |
3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a |
| 43 |
+ |
zero scale will no longer return an error. An Int64 will be returned instead. |
| 44 |
+ |
|
| 45 |
+ |
4. TIBTransaction now has events for Before and After Transaction End and a new function |
| 46 |
+ |
"GetEndAction" allowing the EndAction to be accessed by these event handlers. |
| 47 |
+ |
|
| 48 |
+ |
5. TIBQuery can now handle correctly queries which contain the same keyword parameter |
| 49 |
+ |
repeated multiple times. |
| 50 |
+ |
|
| 51 |
+ |
6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error |
| 52 |
+ |
check used to get in the way of using Stored Procedures, and "Update or Insert" |
| 53 |
+ |
statements. |
| 54 |
+ |
|
| 55 |
+ |
7. Insert, Modify and Delete property Editors now support Query Generation from |
| 56 |
+ |
Stored Procedures. |
| 57 |
+ |
|
| 58 |
+ |
8. Three new examples illustrate the use of the new IB Controls |
| 59 |
+ |
|
