Class Description

  A TDrawPanelHist is a TDialogCanvas specialized to control
  histogram drawing options.
   With the mouse, the user can control:
     - the drawing range in X and Y
     - the drawing options
   When the DRAW button is executed, the selected histogram is drawn
   with the current parameters.

   Use the slider to control the range of the histogram to be drawn.

   The options are documented in TH1::Draw.
/* */

TDrawPanelHist() : TDialogCanvas()
 DrawPanelHist default constructor.

TDrawPanelHist(const char *name, const char *title, UInt_t ww, UInt_t wh, const TVirtualPad *pad, const TObject *obj) : TDialogCanvas(name, title,ww,wh)
 DrawPanelHist constructor.

 DrawPanelHist destructor.

void AddOption(Option_t *option)
 Add option to the current list of options.

void Apply(const char *action)
 Collect all options and draw histogram.

void BuildStandardButtons()
 Create Draw, Defaults and Close buttons.

void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Control mousse events when slider is used in a drawpanel

 This function is called by TPad::ExecuteEvent or TSliderBox::ExecuteEvent
 We return in the first case.
 When called by the slider,  px = 0 and py = 0

void RecursiveRemove(TObject *obj)
  when obj is deleted, clear fHistogram if fHistogram=obj

void SavePrimitive(ofstream &, Option_t *)
 Save this drawpanel in a macro.

void SetDefaults()
 Set default draw panel options.

void SetSame()
 Set graphics option "same".
