CodeSnip Old Code (SVN)

* Changed main window and taskbar captions: removed "DelphiDabbler" and added "v4 preview".
* Added new TAppInfo.ProgramCaption constant to store window and task bar captions.

* Renamed some method of TMainDisplayMgr and replaced all properties with methods.
* Updated using code.

Changed how database update events are handled:
* New event handler added to TMainDisplayMgr for database view item changes: adding, updating and deletion of snippets and categories.
* Removed category and snippet change handling code from TMainForm's database change event handler.

Removed all calls to Query.Update. No longer needed in database change event handler since database itself now updates query where necessary after database changes, and before events are triggered.

* Added new "NewTab" property to TViewItemAction.
* Changed TMainForm handling of view item actions to request new detail tab from main display manager when a view item action has NewTab property set to true.

* Added new parameter to TMainDisplayMgr.DisplayViewItem that determines whether view item is displayed in new tab or not.
* Removed debugging code for tab display mode from UMainDisplayMgr unit.
* Minimal changes to FmMain unit to work with revised TMainDisplayMgr.DisplayViewItem method.
* Changed behaviour of displaying certain view items: welcome page never overwrites tabs, history and main view items always overwrite and new snippets and categories always use new tabs.

Modified database loading code to show "welcome" page after database is first loaded but to show "database updated" page after database re-loaded following online update or restoration of user database backup.

* Added new TMainDisplayMgr.ShowWelcomePage method.
* Removed TMainForm.DisplayWelcomePage method and replaced calls with calls to TMainDisplayMgr.ShowWelcomePage.

* Removed action that selects a detail pane tab from View category (now uncategorised) and renamed it to actSelectDetailTab. Changed to uncategorised because no longer on view menu.
* Removed actSelectDetailTab's OnUpdate event handler and renamed OnExecute change handler.

* Added new Update method to IQuery and its implementation that updates query: refreshes or resets if can't refresh.
* Modified TMainForm to use IQuery.Update.
