Hi,

This, unsurprisingly, has come up before

It's possible to have a window that looks round - just use round imagery that leaves the parts of the window rectangle outside the circle part transparent. There are two issue with this, one solvable, one not.

Issue the first: Default hit-testing for Windows is done based on a simple Rect structure. It is however possible to code a new window subclass that overrides this behaviour to offer custom hit-testing.

Issue the second: Clipping. Clipping of child windows and imagery is done based on a Rect. There is currently no simple method to overcome this limitation (if you want a non-simple method, it effectively involves rewriting half of CEGUI!).

If you do decide to write a new window type, I discuss how to go about that in this post (rest of the thread is likley not relevant to you. And no, I did not yet get around to that example I mention towards the end of the thread!).

For a past discussion about this topic, please refer to this thread
