[Drawkit] validateMenuItem:

[V1ru8]

Hi Graham,

This is my method:

@interface MyDKViewController : DKViewController {

}
- (BOOL)validateMenuItem:(NSMenuItem *)menuItem;
@end
@implementation MyDKViewController
- (BOOL)validateMenuItem:(NSMenuItem *)menuItem {
     NSLog(@"- (BOOL)validateMenuItem:(NSMenuItem *)menuItem");
     return TRUE;
}

@end

That should enable all menu items right?

To use this controller I set it in the -  
(void)windowControllerDidLoadNib:(NSWindowController *) aController  
method of my subclass of DKDrawingDocument.

  DKDrawingView *view = [self mainView];
     DKViewController *controller = [[MyDKViewController alloc]  
initWithView:view];
     [view setController:controller];

Maybe thats the  wrong way? (maybe I really oversee something very  
dump here... :-/)

If I don't set my own controller and add the following breakpoint:  - 
[DKViewController validateMenuItem:] it breaks when I access a menu.


Regards,
Thomas
