Bevel Button Menu Constants

NEW WITH THE APPEARANCE MANAGER

You can pass one or more of these constants in the initialValue parameter of NewControl to create a bevel button with a menu of a certain behavior. Bevel buttons with menus have two values: the value of the button and the value of the menu. You can specify the direction of the pop-up menu arrow (down or right) by using the kControlBevelButtonMenuOnRight bevel button variant.

enum{
   kControlBehaviorCommandMenu    = 0x2000, 
   kControlBehaviorMultiValueMenu = 0x4000 
}; 

Constant descriptions

kControlBehaviorCommandMenu

If this bit is set, the menu contains commands, not choices, and should not be marked with a checkmark. If this bit is set, it overrides the kControlBehaviorMultiValueMenu bit. This constant is only available with Appearance 1.0.1 and later.

kControlBehaviorMultiValueMenu

If this bit is set, the menus are multi-valued. The bevel button does not maintain the menu value as it normally would (requiring that only one item is selected at a time). This allows the user to toggle entries in a menu and have multiple items checked. In this mode, the menu value accessed with the kControlMenuLastValueTag will return the value of the last menu item selected.
