Re: Changing canvas size

Hello Rene,

Thank you for your comment.

SetCanvasSize works well to define the canvas size. But it has side effects. After calling SetCanvasSize, scroll bar appears because window size itself is not changed. And the resize box does not work anymore.

Do you have any further idea?
