Hi folks,
I have got a pretty weird bug in my code, which I'm unable to find.
The situation is as follows: I have a window, which is loaded from
another nib than MainMenu.nib The Nib owner of my object is
FMDelegate. The window contains a NSOutlineView, which should display
all font families active in system.
The bug is that sometimes the outline displays empty. I used a few
dozens of NSAsserts to find the problematic place but didn't find
anything. I added a button to window, which is used just for invoking
debuger and using this technique I was able to stop in problematic
case. (the problem doesn't show always) To my suprise, the pointers to
window objects - created in IB - were empty!? It leads me to idea that
I somehow harm the initialization process but I have no idea what's
wrong. Let me show you some code:
Engine is a pointer to FMEngine object, which is a datasource for
outline view.
FMDelegate.m
- (void)awakeFromNib
{
[self showFontList:nil];
}
- (IBAction)showFontList:(id)sender
{
if (!fontListController)
{
[NSBundle loadNibNamed:@"FontList" owner:self];
}
[fontListController showWindow:[fontListController window]];
}
FMFontListController.m
- (id)init
{
if (self == [super init])
if (self = [super init])
or
if ((self = [super init]) != nil)
