Noel, if you're working on resizable sheets, the real tricky part is going to be reconciling the position of the sheet with respect to the mouse cursor (because the sheet will automatically re-center itself over its owner when it's resized).
Usually, when you resize a window, your cursor stays over the resize handle while you resize the window. But if the window were to reposition itself underneath you while you were dragging, this would change things -- and make it fairly confusing for the user. It's almost as if you want the sheet to hold off on repositioning itself until you release the mouse, and then transition smoothly to its new position. -T On Tue, Oct 27, 2009 at 9:50 AM, Greg Brown <[email protected]> wrote: > If the preferred size is not explicitly set, the window is set to its > default size and we disallow resizing.
