Re: Label with fixed size

[rastersoft <raster rastersoft com>]

I was trying to fix the layout code in Slingshot, the Elementary OS's 
app launcher. The problem is how to create a button with a text and an 
icon inside, but with a fixed width, and putting several of those 
buttons inside a Gtk.Grid, and finally, several grids inside a Gtk.Stack 
to allow several pages with nice swap animations.

Anyway, as I said, I found how to do it, by overriding the 
"get_preferred_width" method in the Label widget to make it return 
always the desired width, and putting it inside a Gtk.Fixed widget.
