Class Description

 This class handles GUI labels.

TGLabel(const TGWindow *p, TGString *text, GContext_t norm, FontStruct_t font, UInt_t options, ULong_t back) : TGFrame(p, 1, 1, options, back)

 Create a label GUI object. TGLabel will become the owner of the
 text and will delete it in its dtor.

TGLabel(const TGWindow *p, const char *text, GContext_t norm, FontStruct_t font, UInt_t options, ULong_t back) : TGFrame(p, 1, 1, options, back)

 Create a label GUI object.

~TGLabel()

 Delete label.

void SetText(TGString *new_text)

 Set new text in label. After calling this method one needs to call
 the parents frame's Layout() method to force updating of the label size.
 The new_text is adopted by the TGLabel and will be properly deleted.

void DoRedraw()

 Redraw label widget.
