onDragOver (Button.onDragOver handler)
onDragOver = function() {}
Invoked when the user presses the mouse button outside of the button and then drags the
pointer over the button. You must define a function that is executed when the event handler is
invoked.
Note: The
onDragOver Event Handler is supported for Flash Lite 2.0 only if
System.capabilities.hasMouse is true or System.capabilities.hasStylus is
true
.
Availability: ActionScript 1.0; Flash Lite 2.0
Example
The following example defines a function for the onDragOver handler that sends a
trace()
statement to the Output panel. Create a button called
my_btn on the Stage and enter the
following ActionScript on the Timeline:
my_btn.onDragOut = function() {
trace("onDragOut: "+this._name);
};
my_btn.onDragOver = function() {
trace("onDragOver: "+this._name);
};
When you test the SWF file, drag the pointer off the button instance. Then, while pressing
the mouse button, drag onto the button instance again. Notice that the Output panel tracks
your movements.
