Bevel Button Menu Constants
You can pass one or more bevel button menu constants in the high byte of the minimumValue
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. The bevel button menu constants are available with Appearance Manager 1.0 and later.
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.
