In a numeric control I'm trying to substitute the increment/decrement buttons with simple triangles facing up/down respectively.
I understand it's possible to do this under Advanced>Customize. The problem I have is that I can only change the appearance of the buttons in the state where they are not activated. As soon as I click on one of them the original shape appears for as long as the button is pressed.
Is it possible to change this activated button as well?
In the control editor, customize mode, right-click on the increment
picture. You'll see the item Picture Item>. That allows to select
which picture state you want to edit.
