Re: transparent canvas working in gtkextra-2?

I still don't understand what you are trying to do, If you want to show 
other widgets, use the gtkfixed capabilities as I do with the buttons in 
testgtksheet. That's the only way to show other widgets inside a canvas. 
If what you want is to do something called MDI of Window in Window, 
that's not possible with gtk. You can use a notebook to diplay the plot 
in one tab and the sheets in other tabs. You can show buttons or icons 
in a canvas and get a sheet to appear on a different window when you 
click. Those are some ideas. But again, I still don't get it. What are 
you exactly trying to do?
