How to show an arrow sign in the menu item area?
Want to show an arrow sign which points to the right and represents the right direction shortcut key in a menu item area. In the "NewMenuItem()" , if specifing 'VAL_RIGHT_ARROW_VKEY' as the shortcut parameter, it just shows the word "Right" not what I expected the arrow sign.
That means I must add a sub item, and it will popup a specified menu window, it likes the following picture:
But I just want approch this effect:
this shoud be a panel not a sub menu.
