Thread-topic: NSWindow custom controller class not displaying window
I'm just starting out in Cocoa and am working my way through some examples in a (rather good) book. One of the tasks is to make a 2nd window (a NSPanel actually) which can be launched from a menu command (e.g. application preferences) in the main menu. Rather than including it in the main nib, a separate nib is constructed, which is loaded and opened when needed. It stays in memory for future. I have a menu action which creates a new instance of a custom controller class, and calls its showWindow action, roughly as below:
- (IBAction)showPreferencePanel:(id)sender
{
if(!preferenceController){
preferenceController = [[PreferenceController alloc] init];
}
[preferenceController showWindow:self];
}
Part of the custom controller looks like this:
- (id)init
{
self = [super initWithWindowNibName:@"Preferences"];
return self;
}
There was another method which I'm afraid I don't have in front of me, which was a delegate function called when the window was opened (similar to awakeFromNib). I put a few log items in, and can confirm that:
- the nib had been located and loaded
- the showWindow method is being called in the custom controller
- the delegate has been triggered, suggesting the window has been opened OK.
My problem is: I don't see the window (panel) on the screen when I run the app and select the menu command. There are no errors showing as such.
Can anyone shed any light on this? The nib file was made from scratch, with the file's owner set to a custom controller class (the item above subclassed from NSWindowController). Do I need to somehow identify the 'default' window within my new nib?
Thanks - Richard
