CodeSnip Old Code (SVN)

Reverted all changes made to USearch in r1883, except for copyright date and TODO item. This was done because revised implementation of nested searches in UQuery (see r1889) makes these changes to USearch unnecessary.

Re-implemented code that records and re-applies nested or refined searches. Previous implementation at r1884 was seriously buggy.

XMLDoc commented unit.

Added option to prevent close button from appearing in dialogue box title bar. Also disabled ESC from closing dialogue box. This option applies only to custom message boxes.

Changed spacing around text in custom sized message box buttons.

Removed old TODOs that refer to completed tasks.

Modified IQuery / TQuery to permit searches to be nested, so one acts on results of previous one.
Also added new IQuery.IsSearchActive method and its implementation.

Added new TCompoundSearch search that applies two searches consecutively. These searches can themselves be compounded to give chains of three or more searches.
Also added new factory method to create a TCompilerSearch instance for two given searches.

Noted changes since v4.0 alpha 2 (preview) release.

Converted static TDetailPageLoader class into normal class that gets instantiated in TDetailViewFrame. Modified TDetailViewFrame accordingly.
