Question about NSCell and NSMatrix

[Peron, Stéphane]

Hi all,

I have downloaded appkit methods from apple site (thanks to you :-) ).

Well, I'm working on an application for which the main panel would display a
matrix of objects. 
First, I ve tried to init an NSMatrix object  like that :

NSMatrix matrice = [[NSMatrix alloc] initWithFrame:
rect:NSTrackModeMatrix:classcell:5:1]

where rect is a rectangle defined just before as NSRect

So , it does'nt seem to work. The compiler tell me it can't allocate memory
for this object.
Does anyone know how to init such an object ? 

Secondly, I'd like to display objects in this matrix. I've read the
documentation concerning NSCell and it seems that we only can display text
and images into.
So, Does anyone know how I could display for exemple a button or a
checkbutton in an NSCell object ?
I think the better for me is to have sources of an application that use
these collection of objects. Is there actually such an application among the
Gnustep apps ?

Thanks a lot for your help

Stephane

PS :
Sorry for my bad english :-)
