If I need only an image without the text and I don't need all of the
features in the Gtk.Button I will normally just use a Gtk.Image in a
Gtk.Event container widget, of course that doesn't have all the benefits
a Gtk.Button does but I makes for a quick simple solution to the button
border problem.
I hope that helps.

Hi to all,
i am using the following code in order to set a custom image on top of a Gtk
Button widget in order to be used for a touch-screen application.
Gdk.Pixbuf pixBuf = new Gdk.Pixbuf(byte[]);
pixBuf = pixBuf.ScaleSimple(btn.WidthRequest, btn.HeightRequest,
Gdk.InterpType.Nearest);
btn.Image = new Image(pixBuf);
the button is of 'Text and image" type, but i clear the text propery in
order for the image to be displayed alone. The image is fetched from a
byte[] inside my application and I would like to cover the whole button
area, this is the reason for scaling it to the button width and height
properties.
Everything should work as expected but the result is not perfect. The image
cannot cover the whole button area. A top-left offset is displayed instead,
leaving part of the button control surface uncovered.
Any ideas on how to set the image cover the whole button area?
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.
