Question

In objective C, I’m trying to resize an application window after a button is clicked. If the window was 200×200, a (+) button is pressed to make it 200×210 or the (-) button is pressed to make it 200×190.

I’m just not sure how to set the size of windows after they’re made in the editor.

Don’t have sample code because it’s simple and I’m not sure where to start.

Here you go:

- (IBAction)plusButtonClicked:(NSControl *)sender
{
  NSRect frame = sender.window.frame;

  frame.size.height += 20;

  [sender.window setFrame:frame display:YES animate:YES];
}

Depending whether you want the top or bottom of the window to expand, you may also need:

frame.origin.y -= 20;
