TGTab*¶
The TGTab is user callable. The TGTabElement and TGTabLayout areis a service classes of the tab widget.
TGTabLayout 继承 TGLayoutManager
TGTab 继承 TGCompositeFrame, TGWidget
A tab widget contains a set of composite frames each with a littletab with a name (like a set of folders with tabs).
Clicking on a tab will bring the associated composite frame to the
front and generate the following event:
kC_COMMAND, kCM_TAB, tab id, 0.
TGTabElement 继承 TGFrame
