Thanks for reply
Using CTextView:ocPosToXyPosL/FindDocPos I can find the rectangle dimensions.
Suppose I'm using a rectangular label or an image control with colored rectange as bitmap.
or you can experiment with containing a second control
By calling DrawNow() it will display this second control over the editor but not in the background as you said.
I'm still need to make transparency as you said in first option.
How can I achieve this task, containers in symbian has no alpha channel like in iphone for example )-:
