mdkashif: If you accidentally forgot to read the manual, and you're asking if there's an API to query a rect for its size and position, the first answer would be "read the manual", and if you still can't find it, the answer is "the member variables iTl and iBr are public".

I am often unsure myself about such rectangle positions, and if I need to be sure I just take the whole thing into the debugger and have a direct look. Very simple (if you know how to debug, which you should.)

In this case I would say probably the coordinates are screen-absolute, i.e. the TRect gives the position of the corner of the container's window relative to the whole screen/display.

Ok, then Rect() will give you the net size and position of the container's window. If you shring this rectangle by 10,10 you will draw into a rectangle that leaves a room of 10 pixels free on all four sides of the container window.

Hi i am using this for draw the Ellipse , whole code for this.

TRect rect = Rect();
rect.Shrink( 10, 10 );
gc.SetPenStyle( CGraphicsContext :: ESolidPen );
gc.SetPenColor( KRgbBlack );
gc.SetPenSize( TSize( 5, 5 ) );
gc.SetBrushStyle( CGraphicsContext :: ESolidBrush );
gc.SetBrushColor( KRgbYellow );
gc.DrawEllipse( rect );

It depends *where* you write that code, and which object is "this" i.e. the Rect() method of which object is called by executing your two lines of code.

>>i want to know how we find actual size of TRect
TRect itself is size. What do you mean by that?

>>i mean we consider screen as a rectange on the sthe screen of emulator
If you want to get the screen size then check out CWsScreenDevice::GetScreenModeSizeAndRotation api.

Cheers,
Sri
