Maybe I missed it, but what is the function to close a IGUIWindow? I have a window that allows users to edit text. The window has a 'Submit' button that confirms text edits, but also needs to close the window. I'm using the default close button to close the window and cancel the text edits.

You can remove any gui element with it's remove() function. That works also for the IGUIWindow.

Thank you!
