[ltk-user] Grid question

[Bill]

Hi,

I'm new to Ltk.   I seem to get it to work fine and have seen enough to 
want to really get familiar with it.  However, I have a few questions 
about the layout managers.   Basically, I want to be able to place 
things anywhere on the screen and have them stay relative to one another 
when the screen  is resized.

When creating a grid, who owns it?    If I want a frame to be a grid of 
four by four and to place buttons at 1,0  and 2,3, how is that done?    
It seems that when I try this the first button goes to 0,0 and the 
second button to 1,1.

Also, how do you create an empty frame of a specific size?    Or a nil 
(*tk*) window of a specific size?

And, lastly, are there any more complex examples I can look at?

Thanks,

Bill
