Constructor & Destructor Documentation

◆ TGXYLayoutHints()

TGXYLayoutHints::TGXYLayoutHints ( Double_t  x,
Double_t  y,
Double_t  w,
Double_t  h,
UInt_t  rubberFlag = kLRubberX | kLRubberY 


The x, y, w and h define the position of the widget in its frame and the size of the widget. The unit is the size of a character. The rubberFlag defines how to move and to resize the widget when the frame is resized. Default is moving the X and Y position but keep the size of the widget.
