CodeSnip Old Code (SVN)

Fixed error in handling of revised EActiveTextParserError exception. The exception's Selection property is now only accessed and copied to EDataEntry if it exists!

Moved code that registers memos with TMemoCaretPosDisplayMgr object from FormCreate event handler to InitControls, which is itself called from FormShow. This is because memo window is recreated after FormCreate causing TMemoCaretPosDisplayMgr to lose track of selection change events by hooking into a window that is then destroyed. Registering from FormShow ensures correct memo window handle is used for hook.

Revised error handling to not only select controls containing errors, but, where the controls contain editable text, to select, or place the caret next to, text containing errors.

Partially implemented suggestion in comment to feature request 3105288 so that errors reported when clicking "Render Extra Information" button on Snippets Editor's Extra Information tab now refocuses memo control containing error.

* Created new UMemoCaretPosDisplayMgr unit to take care of displaying caret position of memo controls in associated labels.
* Revised snippets editor to use new TMemoCaretPosDisplayMgr to display memo caret positions and added caret position display for extra information memo.

Corrected copyright date range to be in line with date of last revision.

Added indicator of column and row containing caret in source code edit memo.

* Changed FmUserDBEditDlg.pas to get default mono font name from TFontHelper.
* Rearranged some unit and field declarations.

Modified snippets editor:
* Added support for Ctrl+X (cut), Ctrl+C (copy), Ctrl+V (paste), Ctrl+A (select all) and Ctrl+Z (undo) keyboard short cuts to all edit / memo controls using standard actions.
* Replaced default popup menus of edit controls with custom versions attached to above actions.

* Replaced code that checks validity of Extra active text with a call to TSnippetValidator.ValidateExtra.
* Moved assertions that ensure that all combo boxes have default items selected.
* Simplified TUserDBEditDlg.UpdateReference: now determine valid dependency snippet kinds with a call to TSnippetValidator.ValidDependsKinds rather than hard wiring the details.
* Modified TUserDBEditDlg.ValidateData to use renamed TSnippetValidator.ValidateDependsList method.
