TGListBox Class Reference

A listbox is a box, possibly with scrollbar, containing entries.

Currently entries are simple text strings (TGTextLBEntry). A TGListBox looks a lot like a TGCanvas. It has a TGViewPort containing a TGLBContainer which contains the entries and it also has a vertical scrollbar which becomes visible if there are more items than fit in the visible part of the container.

The TGListBox is user callable. The other classes are service classes of the listbox.

A listbox contains a container frame which is viewed through a viewport. If the container is larger than the viewport than a vertical scrollbar is added.

Selecting an item in the listbox will generate the event:

  • kC_COMMAND, kCM_LISTBOX, listbox id, item id.
