## Class Description

     TGTab, TGTabElement, TGTabLayout

     A tab widget contains a set of composite frames each with a little
     tab with a name (like a set of folders with tabs).

     The TGTab is user callable. The TGTabElement and TGTabLayout are
     service classes of the tab widget.

     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(const TGWindow *p, TGString *text, UInt_t w, UInt_t h, GContext_t norm, FontStruct_t font, UInt_t options, ULong_t back) : TGFrame(p, w, h, options, back)

     Create a tab element. Text is adopted by tab element.

~TGTabElement()

     Delete tab element.

void DrawBorder()

     Draw little tab element.

Bool_t HandleButton(Event_t *event)

     Handle button event in the tab widget. Basically we only handle
     button events in the small tabs.

TGDimension GetDefaultSize() const

     Return default size of tab element.

void SetText(TGString *text)

     Set new tab text.
