MACROMEDIA FLASH 8-LEARNING ACTIONSCRIPT 2.0 IN FLASH - Page 339

Using button and movie clip event handlers 339
To use an on handler and onPress event handler:
1. Create a new Flash document and save it as handlers.fla.
2. Select the Rectangle Tool and draw a large square on the Stage.
3. Select the Selection Tool, double-click the square on the Stage, and press F8 to launch the
Convert to Symbol dialog box.
4. Enter a symbol name for the box, set the type to Movie clip and click OK.
5. Give the movie clip on the Stage an instance name of box_mc.
6. Add the following ActionScript directly on the movie clip symbol on the Stage:
on (press) {
trace("on (press) {...}");
}
7.
Add the following ActionScript to Frame 1 of the main Timeline:
box_mc.onPress = function() {
trace("box_mc.onPress = function() {...};");
};
8.
Select Control > Test Movie to test the Flash document.
When you click the movie clip symbol on the Stage, the following output is sent to the
Output panel:
on (press) {...}
box_mc.onPress = function() {...};
NOTE
Attaching onClipEvent() and on() handlers is not a recommended practice. Instead,
you should put your code in frame scripts or in a class file, as demonstrated
throughout this manual. For more information, see “Using event handler methods”
on page 330 and “Attaching code to objects” on page 746.
