Manages a content area.

It can display and control a hierarchy of multi-column items, and provides the ability to add new items at any time. By default it doesn't map subwindows which are items of the container. In this case subwindow must provide DrawCopy method, see for example TGLVEntry class. It is also possible to use option which allow to map subwindows. This option has much slower drawing speed in case of more than 1000 items placed in container. To activate this option the fMapSubwindows data member must be set to kTRUE (for example TTVLVContainer class)

The TGContainer class can handle the keys:

F7, Ctnrl-F - activate search dialog
F3, Ctnrl-G - continue search
End - go to the last item in container
Home - go to the first item in container
PageUp,PageDown,arrow keys - navigate inside container
Return/Enter - equivalent to double click of the mouse button
Ctnrl-A - select/activate all items.
Space - invert selection.
