How to give NSWindow a particular background color

Question

I am writing a cocoa application which has a NSWindow. I want to change the background color of the window to a specific color. But the window properties in the inspector only provide "Textured Window" alternative. How can I make the color of the window as desired?

Answer 1

Try calling the instance method setBackgroundColor: with a color on your window instance. What's in a name.. ;)

Like this:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    // Option 1
    [self.window setBackgroundColor: NSColor.whiteColor];
    // Option 2 - using dot syntax
    self.window.backgroundColor = NSColor.whiteColor;
}

Answer 2

The simplest way to change window background is to set it directly in your .xib file.

No code at all:

1. Select your window (NSWindow class should appear in Class field)
2. Click [+] button under the User Defined Runtime Attributes
3. Type "backgroundColor" and select Color
