[ltk-user] Grid question

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
