TStatusBar.OnDrawPanel Event

Occurs when a status panel needs to be redrawn.

Pascal

property OnDrawPanel: TDrawPanelEvent;

C++

__property TDrawPanelEvent OnDrawPanel;

Description

The OnDrawPanel event occurs when a status panel needs to be redisplayed—for example, when the user resizes the status bar. The Rect parameter gives the (new) dimensions of the status panel. OnDrawPanel occurs only if the status panel's Style property is set to psOwnerDraw.

C++ Examples:

Copy Code

/*
The following code is the OnDrawPanel event handler of a
status bar.  It draws each panel of the status bar, adding
text and icons stored in ImageList1. The image list contains
as many icons as there are header sections.  This example
requires a populated image list and a statusbar with several
panels added to the Panels property.  Select each panel and
set the Style property to psOwnerDraw.
*/
void __fastcall TForm1::StatusBar1DrawPanel(TStatusBar *StatusBar,
        TStatusPanel *Panel, const TRect &Rect)
{
  TCanvas *canvas = StatusBar->Canvas;
  canvas->Brush->Color = clRed;
  canvas->FillRect(Rect);
  canvas->Font->Color = clYellow;
  ImageList1->Draw(canvas,Rect.Left,Rect.Top, Panel->Index, true);
  canvas->TextOut(Rect.left + 30, Rect.top + 2, "Panel" + IntToStr(Panel->Index));
}
