Ok, this might take a bit to explain.
On my form, I have dynamically created my menu's and toolbars (just because of the over head the development studio creates).
I have no problem with creating these....
On my toolbar, I created my icons 24x24.
On one of my toolbar buttons, I have it drop down to display a list of colours. In the list, I don't plan on having anything except checkmarks.
It appears that my dropdown menu uses checkmarks which are 24px wide as opposed to a standard 16px used in menu's.
Does anyone know how I would force it to use 16px, while the remainder of the toolbar is 24px
Some code of how I'm setting it up:
