A Boolean value that indicates whether the button is transparent.
- macOS 10.0+
The value of this property is
true if the button is transparent,
false otherwise. A transparent button never draws itself, but it receives mouse events, sends its action, and tracks the mouse properly. A transparent button can be useful for sensitizing an area on the screen so that an action gets sent to a target when the area receives a mouse click. Setting this property causes the button to redraw if necessary.
