Hi, does anyone know how you can tell when a control is no longer being drawn?
e.g. If I change from Tab0 to Tab1 on a TabNavigator control, the original canvas is no longer drawn (but obviously it's visible property is still set to true). So how does that canvas know not to draw? I would like to remove event listeners while my control is not visible, and then re-add the event listeners when it becomes visible again (I say visible lightly, I mean added / removed from the drawing list). Any ideas? Mark
