[Mono-list] Gtk# component for buttons like The Gimp toolbox???

[Francisco M. Marzoa]

Hello,

For those whose does not known The GiMP yet, it's an image mainpulation
program and has a toolbox in its main window plenty of icon buttons in
the form of a grid. These buttons are fixed in size, so when you resize
the window, the number of icons per row is changed to fill the available
space.

You can see the toolbox on the left of this image:

So, my question: is there a GTK# component -or compatible- to create a
grid of buttons like that one that automatically adapts to available
space???

Thanks in advance,
