Usage
componentInstance.invalidate()
Returns
Nothing.
Description
Method; marks the object so it is redrawn on the next frame interval.
This method is primarily useful to developers of new custom components. A custom
component is likely to support a number of operations that change the component’s
appearance.
Often, the best way to build a component is to centralize the logic for updating the
component’s appearance in the
draw() method. If the component has a draw() method, you
can call
invalidate() on the component to redraw it. (For information on defining a
draw() method, see “Defining the draw() method” in Using Components.)
