[MACTCL] Button background

[Brad P. <bp...@li...>]

Is there a way to set the button background?  Or to make it take on  
the background of the widget it is on top of?  For instance on the Mac  
I do this:

	wm geometry . 300x300
	button .b -text "Hello"
	grid config .b -row 0 -column 0

This looks good since the border around the rounded button is the same  
color as the background of "." but what if its changed:

	. configure -background "#007fff"

Now you get a light blue window with a button in the middle but the  
button still is in a white square.  Tried to change it like this but  
none of these work:

	.b configure -background "#007fff"
	.b configure -activebackground "#007fff"

Is there a way to solve this on the Mac?  Is it to do with using  
native widgets?
