Question

I have a window, which I set setContentBorderThickness:42 forEdge:NSMinYEdge.

Now, when I do [[window contentSize] frame] it still shows the dimensions of the window (minus the top bar with title and buttons), but it wont subtract the 42 of the border thickness.

Please, how do I get the proper dimensions of the empty area?

Answer 1

You should use not contentSize but contentView. And if You use 42 pixels height BorderThickness than just subtract that height from Your window view’s height like this:

NSRect windowFrame = [[window contentView] frame];

windowFrame.size.height = windowFrame.size.height - [window contentBorderThicknessForEdge:NSMinYEdge];

NSLog(@"TRUE height: %f",windowFrame.size.height);
