CodeSnip Old Code (SVN)

* 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.

Removed cInfoTab constant that referred to a fixed tab in former implementation of Details pane.

Major revision of TMainDisplayMgr and TDetailFrame to better support multiple tabs and to eliminate problems of first attempt at multi-tab support at r1616:
* Interface type IEditableTabbedDisplayMgr, supported by TDetailFrame, replaced by IDetailPaneDisplayMgr and now redundant TCloseTabAction removed.
* Complete re-write of way TMainDisplayMgr handles database update events. TMainForm modified to call new TMainDisplayMgr methods.
* Detail pane selected tab no longer persisted in settings.
* Some debug code added to TMainDisplayMgr to help debug display of views in new and existing tabs: must be removed in later revisions.

* Modified TMainDisplayMgr to support changes in IEditableTabbedDisplayMgr.
* Changed code that clears display to clear overview pane and either current detail tab display or to delete all tabs.
* Modified FmMain to delete all tabs before re-displaying a re-loaded database.

Added support for closing selected tab in Details pane, including new View menu item and action. New methods added to IEditableTabbedDisplayMgr and TMainDisplayMgr to support this.

Made minimal changes to support multiple tabs in details pane:
* Heavily revised FrDetail unit to support multiple tabs
* New view menu item to create new tab - replaces redundant "Detailed Information" menu item. Supporting code in TMainDisplayMgr.
* New GetCurrentView method of IViewItemDisplayMgr and implementations.
* Change in parameter list of IWBCustomiser methods to prevent memory leek.
* New IEditableTabbedDisplayMgr interface and support in FrDetail unit for creating new tabs.
* Change in how Detail Pane Change method is handled by notifier object.

* Removed unused showTestUnit Javascript routine and equivalent method from external object implementation.
* Removed corresponding method and action setter from INotifier and ISetActions and implementation in TNotifier.

Created new "Compile" top-level menu and moved Test Compile and View Compile Errors options from Database menu and View Test Unit from View menu to new menu.

Removed support for command that viewed compiler errors for a single compiler, including:
* Updated External object to remove ViewCompilerLog method along with associated JavaScipt and Notifier methods.
* Renamed external object interface to IWBExternal7 and set version attribute to 7.0.
* Removed associated action and associated factory method for it.
* Support from main form for displaying the associated dialog box.
