CodeSnip Old Code (SVN)

Changed visibility of TMainForm.InitForm method from strict private to strict protected: had hint that was lower visibility than ancestor class.

* Removed all code that is excluded from Delphi 2009 / 2010 by conditionally defined symbols.
* Removed related $IFDEFs. Unused symbols removed from CompilerDefines.inc.
* Removed UAltBugFix.pas unit from project and removed all references to it since its functional code was excluded by conditional symbols on Delphi 2009 and later.

Moved code that handles application level exceptions from UExceptions into FmMain since the code is mainly concerned with UI matters.

Merged delphi2010-port branch back into trunk.

Replaced explicit command line check for '-localhost' from main form and replaced by calls to new TWebInfo.UsingLocalHost method and TWebInfo.LocalHost public constant.

* Moved setting of default main form splitter position from main form file to TWindowSettings.
* Moved declaration of constants determining minimum sizes of main form panels from main form file to public constants of TWindowSettings and change TMainForm to use the new constants.

Added [localhost] to main form caption if CodeSnip is accessing online web services via localhost for test purposes.

Made overview pane treeview expansion state persistent when user database is changed by adding, deleting or updating a snippet:
* Added new SaveTreeState and RestoreTreeState methods to IOverviewDisplayMgr and its implementation in FrOverview.pas.
* Added new PrepareForChange and FinalizeChange methods to TMainDisplayMgr and modified TMainForm.SnippetsChangeHandler to call these methods when database changes.

Made further changes to TMainForm.SnippetsChangeHandler:
* Added handler for Snippets' evBeforeDeleteCategory event that clears history list and overview pane.
* Removed clearing of history list from other handlers since this is now taken care of when handling evBeforeDeleteCategory and evBeforeDeleteRoutine.
* Groped together identical event handlers in case statement.

Added handler for Snippets' evBeforeRoutineDelete event to TMainForm.SnippetsChangeHandler that clears history list and overview pane. This is to try to overcome the "invalid cast" error due to dangling references to deleted routines. This event is called before the actual snippet object is freed, so references to the snippet are valid here.
