NSTextField Color issues

Question

I am dynamically adding a NSTextField to a window and I am having issues with rendering. I am setting the background color to be black and the text color to be white. These both work but their is what appears to be a rectangle that is part of the text that is always white. Does anyone know what I might be doing wrong? How can I get rid of the white background that is just around the text? Code is as follows:

//Create rectangle to size text field

NSRect textFieldRect = NSMakeRect(300, 300, 300, 54);

//Instantiate text field and set defaults
NSTextField* textField = [[NSTextField alloc] initWithFrame:textFieldRect];

[textField setFont:[NSFont fontWithName:@"Arial" size:48]];

[textField setTextColor:[NSColor whiteColor]];

[textField setStringValue:@"Some Text"];

[textField setBackgroundColor:[NSColor blackColor]];

[textField setDrawsBackground:YES];

[textField setBordered:NO];

[[window contentView] addSubview:textField];

I tried your code on Mac OS X 10.6.4.

Inside the application delegate:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {
    NSRect textFieldRect = NSMakeRect(300, 300, 300, 54);
    NSTextField* textField = [[NSTextField alloc] initWithFrame:textFieldRect];
    [textField setFont:[NSFont fontWithName:@"Arial" size:48]];
    [textField setTextColor:[NSColor whiteColor]];
    [textField setStringValue:@"Some Text"];
    [textField setBackgroundColor:[NSColor blackColor]];
    [textField setDrawsBackground:YES];
    [textField setBordered:NO];
    [[window contentView] addSubview:textField];
}

And this is the result

I can't see any white box.
Maybe you are using a different OS.
Or maybe you have some other views on top of each other that are causing the weird effect you are talking about.

Try setting refusesFirstResponder = TRUE property of your NSTextField object. I have come across behavior you described in 10.7, in 10.6 everything works as expected.
