Class Description

 Is a layout manager where the position and the size of each widget   
 in the frame are defined by X / Y - coordinates. The coordinates     
 for each widget are defined by the TGXYLayoutHints. Therefore it     
 is not possible to share a layout hint for several widgets.          
 The coordinates (X, Y) and the size (W, H) are defined in units      
 of the size of a typical character. Also the size of the             
 TGCompositeFrame for which a TGXYLayout manager is used has to be    
 defined in its constructor in units of the size of a character!      
 It is not possible to use any other layout hint than the             
 TGXYLayoutHints for this layout manager!                             
 The rubberFlag in the constructor of the TGLXYLayoutHins defines     
 how the position and the size of a widget is recalculated if the     
 size of the frame is increased:                                      
 - kLRubberX: The X - position (left edge) is increased by the same   
              factor as the width of the frame increases.             
 - kLRubberY: The Y - position (upper edge) is increased by the same  
              factor as the height of the frame increases.            
 - kLRubberW: The width of the widget is increased by the same        
              factor as the width of the frame increases.             
 - kLRubberY: The height of the widget is increased by the same       
              factor as the height of the frame increases.            
 But the size never becomes smaller than defined by the               
 TGXYLayoutHints and the X and Y coordinates becomes never smaller    
 than defined by the layout hints.                                    
 This layout hint must be used for the TGXYLouyout manager!           
 Example how to use this layout manager:                              
    : TGMainFrame(gClient->GetRoot(), 30, 12)                         
    // frame is 30 character long and 12 character heigh              
    SetLayoutManager(new TGXYLayout(this));                           
    // create a button of size 8 X 1.8 at position 20 / 1             
    TGTextButton * button;                                            
    button = new TGTextButton(this, "&Apply", 1);                     
    AddFrame(button, new TGXYLayoutHints(20, 1, 8, 1.8));             
    // create a listbox of size 18 X 10 at position 1 / 1.            
    // The height will increase if the frame height increases         
    TGListBox * listBox;                                              
    listBox = new TGListBox(this, 2);                                 
    AddFrame(listBox, new TGXYLayoutHints(1, 1, 18, 10,               
             TGXYLayoutHints::kLRubberX |                             
             TGXYLayoutHints::kLRubberY |                             
             TGXYLayoutHints::kLRubberH ));                           
 Normaly there is one layout hint per widget. Therefore these         
 can be deleted like in the following example in the desctuctor       
 of the frame:                                                        
    // Destructor, deletes all frames and their layout hints.         
    TGFrameElement *ptr;                                              
    // delete all frames and layout hints                             
    if (fList) {                                                      
       TIter next(fList);                                             
       while ((ptr = (TGFrameElement *) next())) {                    
          if (ptr->fLayout)                                           
             delete ptr->fLayout;                                     
          if (ptr->fFrame)                                            
             delete ptr->fFrame;                                      

TGXYLayoutHints(Double_t x, Double_t y, Double_t w, Double_t h, UInt_t rubberFlag)
 Constructor. 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.
