Changing the initial layout

Hi All,

Trying to build my first Cocoa project, I'm having
lot's of fun, but there is this thing I can't figure out.

I'm building a game, on the right I have an openGL
thing and on the left I have Tabpages. Now I've created
4 different Tab's no problems there.

The problem is that now allways all tabs are applicable,
when the application just started, I just want to show 2
of them. So I've to do something like:

[menuBar->AdvancedTab retain];
[menuBar removeTabViewItem: menuBar->AdvancedTab];

But the thing is I've no clue where to put this code, when I put it in
any init function, I allways get an exeption that tells me that there
are no tabpages yet, same with every other place I tried. Same with
awakeFromNib.

Could you please advise how I can change the GUI just before the user
first sees it?

Thanks,
Bas

Thanks for your help, I'll rebuild the problem in a new and clean
application,
an will describe what I do along the way....

1 Create new Cocoa application
2 Open MainMenu.nib
3 drag in a NSTabView
4 open the inspector of the NSTabView
5 make it use the class MyTabView
6 add two outlets for each 'default' tabpage of type NSTabViewItem
7 connect the two NSTabViewItem's with the blue lines to the tabpages.
8 create the MyTabView.[m|h]
9 quit IB and back to xCode, add the two files just created.
10 Make NSTabView the base class of the new class
11 add
- (void)awakeFromNib;
just before @end in the .h file
12 add
- (void)awakeFromNib
{
[self removeTabViewItem: tabOne];
}
just before @end in the .m file.

13 Hit Build and Go, Let's see....



Hmm, This works!

I've no clue what I forgot in my main application, but thanks a lot
for helping me, I'd given up on the awakeFromNib thing, you made
my try again!

Thanks,
Bas
