Bevel Button Behavior Constants

NEW WITH THE APPEARANCE MANAGER

You can pass these constants in the high byte of the minimumValue parameter of NewControl to create a bevel button with a specific behavior.

enum {
   kControlBehaviorPushbutton     = 0,
   kControlBehaviorToggles        = 0x0100,
   kControlBehaviorSticky         = 0x0200,
   kControlBehaviorOffsetContents = 0x8000
};

Constant descriptions

kControlBehaviorPushbutton

Push button (momentary) behavior. The bevel button pops up after being clicked.

kControlBehaviorToggles

Toggle behavior. The bevel button toggles state automatically when clicked.

kControlBehaviorSticky

Sticky behavior. Once clicked, the bevel button stays down until your application sets the control's value to 0. This behavior is useful in tool palettes and radio groups.

kControlBehaviorOffsetContents

Bevel button contents are offset (one pixel down and to the right) when button is pressed.
