Checkbox size in Listview

Cant seem to find a solution to this in the forum.....
Im writing a POS system for a touchscreen and using listviews with checkboxes.....ive changed the font size of the listview to 12 but the checkbox still remains at 8 i think....it doesnt get bigger or smaller no matter what font size i use......how do i change size of the checkbox as well?

Ive never used API calls or subclassing, so if that is the only way to do it, please guide me in it :)

Thanx

I don't think there is any way to resize the checkboxes to make them easier to see on smaller screens. Perhaps you should consider making a custom one using two images and have it so it displays one if checked and another if not :-)
