get size of nswindow
cocoa, nswindow, size
Solution
If you implement the method
`- (NSSize)windowWillResize:(NSWindow *)sender toSize:(NSSize)frameSize`
on an object you set as the delegate of the window, it will be called whenever the window changes size. From there you can update the text field you use for displaying the size.
Problem
Is there any way I get get the size of an NSWindow (in pixels) and display it? So when the person resizes the window the text will change and display the new size.
