Trying to create a simple full screen application, initially without any text, image or buttons / bars. Just to get the basic hang of windowing.

When I run this application however, it displays nothing. Any suggestions welcome.

#import "MyApplication.h"

@implementation MyApplication

- (void) applicationDidFinishLaunching: (id) unused
{
UIWindow *window;
struct CGRect rect = [UIHardware fullScreenApplicationContentRect];
rect.origin.x = rect.origin.y = 0.0f;

window = [[UIWindow alloc] initWithContentRect: rect];
mainDisplay = [[UIView alloc] initWithFrame: rect];

[window orderFront: self];
[window makeKey: self];
[window _setHidden: NO];
[window setContentView: mainDisplay];


}

@end

The problem is that you aren't putting anyhting into the main window, so nothing shows up. Don't forget UIView.

Take a look at the Bluetooth.app source I posted in this same subforum.

its fullscreen not fullScreen.
and i think you need to add UIView *mainDisplay

Thanks Skylar. I thought it must be something like that, but was hopeful that I could initialise screens without the need to put anything in them. Alas that's not the case.

Anyway, onwards and upwards and thanks for the code.
