I think the padding in the button is a theme-level property, i.e. not really supposed to be touched by app writers. Despite this, you can override it using a gtkrc settings file for your app, or by code, e.g. something like http://anonsvn.mono-project.com/viewvc/trunk/monodevelop/main/src/core/MonoDevelop.Ide/MonoDevelop.Ide.Gui/DragNotebook.cs?r1=135850&r2=136641 You might have to poke around in the gtk+ docs to find the right property. -- Michael Hutchinson http://mjhutchinson.com _______________________________________________ Gtk-sharp-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/gtk-sharp-list
