indeed, moving that into the awakeFromNib:
[characterWindow makeKeyAndOrderFront: self];
NSLog(@"awakeFromNib: the key Window: %@", [[NSApplication
sharedApplication] keyWindow]);
make the window pop up. Unfortunately also on startup of the application,
whereas I only want it to be
around once I either load or create a new document. Something to figure out.
When I edit the document to edit the name of the character, I have this:
- (IBAction)nameChanged:(id)sender {
NSString *newName = [self.name stringValue];
[self.character setValue:newName forKey:@"name"];
NSLog(@"calling updateChangeCount!!!");
[self updateChangeCount:NSChangeDone];
NSLog(@"isDocumentEdited? %i", [super isDocumentEdited]);
[self checkIfWindowIsKey]; // Check if the window is key
}
- (void)checkIfWindowIsKey {
// commented out approach doesn't work only calling my window directly as below
// if ([[self windowForSheet] isKeyWindow]) {
if ([characterWindow isKeyWindow]) {
NSLog(@"The document window is the key window.");
} else {
NSLog(@"The document window is not the key window.");
}
}
creates output:
Character's name changed to: Bula
calling updateChangeCount!!!
isDocumentEdited? 1
The document window is the key window.
However, the save, save as, .... menu items, they all stay grayed out.
when I override the
- (BOOL)isDocumentEdited {
return YES;
}
then the "save all" menu item is active, and I can save the file. But "save",
save as... stay gray.
Somehow, I'm not properly marking the document as "dirty" ?
I guess probably something similarly simple and stupid ;)
thanks,
Sebastian
