CodeSnip Old Code (SVN)

New unit that implements TUniqueId, a static class that generates globally unique id strings.

* Removed potential bug from Add Unit action's updating.
* Removed unnecessary calls to Init before some edit data structure assignments.
* Made user-defined category get selected by default when adding a new snippet.
* Replaced some validation code with calls of new or revised methods in TSnippetsValidator.

* Changed TSnippets.UpdateRoutine to ignore case when checking if a snippet's name has changed. Snippet names are not case sensitive.
* Modified TRoutineData.Assign to permit Extra property to be nil before calling the method.
* Removed unnecessary call to Init from TRoutineEditData.Assign.

* Added new ValidateSourceCode, ValidateDescription, ValidateName name and overloaded HasValidDependsList methods to TSnippetValidator. HasValidDependsList takes snippet name and edit data instead of a snippet reference as parameters
* Modified TSnippetValidator.Validate to check snippet name, description and source code in addition to dependency list.

Changed topic to reflect changes to Snippets Editor's Compile Results tab.

Added some new todos arising from recent changes.

Added new UCompileResultsLBMgr, UDropDownButtons and ULEDImageList units.

Compile Results tab of snippets editor revised:
* "Select a Compiler" and "Selected Compiler Result" list boxes have been replaced by a single list box. This not only displays the compile result for each compiler but also provides a button for each one which enables the compile result to be selected from a drop down list.
* List box management code has been moved out into a separate UCompileResultsLBMgr unit.
* Removed TUserDBEditDlg.CLBRoutineRefsDrawItem method. Owner drawing of check list boxes now performed in TSnippetsChkListMgr.
* Image list containing LEDs was removed and replaced by a new custom, dynamically created, image list that knows how to map compile results onto the LEDs. As a result some buttons now have actions set in code to ensure they use the new custom image list.
* Brief help text applied to compile results pages.

New UCompileResultsLBMgr unit. Defines classes that manages display, editing and interaction with a list box that displays compiler results.

New UCompileResultsLBMgr unit that defines a class that is used to manage image lists containing drop down button images for display in UI widgets.
