I am using GtkMenuToolButton and it has a button and a menu. When you click on the arrow the menu is opened. I'd like to make the button open that same menu as well. Simply emitting "show-menu" in the "clicked" callback did not work. Please help how to make this work.
I have currently ended up doing this:

Instead of GtkMenuToolButton I have GtkToolItem with custom content
In custom content I have GtkMenuButton
Inside that one, I delete the default GtkArrow and replace it with 1x2 GtkGrid which has a Label + GtkArrow

As a whole it does what I want =)
How to make GtkMenuToolButton open the same menu when 'clicked' signal is emitted?
