TCanvas, clear?

[inetd]

How to clear the contents drawn in TCanvas?

 

[hennep]

don't know if there is a better way but this works:

TRect r;
r.left = 0;
r.top = 0;
r.right = this->Width;
r.bottom = this->Height;
this->Canvas->Brush->Color = clYellow;
this->Canvas->FillRect(r);

Use FloodFill with a border color not used in
the current canvas, for instance:
Form1->Canvas->FloodFill(1,1,0x00fefefe,fsBorder);
Where "fefefe" is the limiting, non exixting color in GBR notation.

I have got an idea!! When you have for example Form1->Canvas you could use Repaint. When you have an image canvas then you could write Form1->Image1->Picture=NULL. I use this kind of code in my programs
