  Also, there is an extra problem. When you set the frame width to be the 
width of the text field plus the width of the button, the display of the 
original NSComboBox is OK. But when you click on the button and the list 
appears, the scroller is again inside the text field. I mean it takes some 
room, so the space for texts in the list is too short again.
  I think that in Cocoa, the scroller does not steal space from the text 
fields, it is added on the right of the list (under the button). Isn't 
that better ? Like that there is not this width problem in the list, and 
because it is on the right of the list, the text fields of the list are 
aligned with the text field of the NSComboBox. Also the use of the mouse 
pointer is easier, because you do not have to go from the button on the 
right to the scroller on the left ; you just have to move the mouse down.
  What is your opinion ?

Goodbye,
