Explain:
We create three checkbox and button.
We select checkbox and click OK button.
The control goes to actionscript and call display function. Because in button, we use click=”display(event)”.
We use if control statement, to decide which checkbox is selected.
Step 4:
Already we have build.xml. so no need to create build.xml. you just include the following coding into the build.xml
……
……
< exec executable='${compiler}' failonerror='true' >
< arg line='-output F:\FLEXWORKSPACE\FlexPro\CheckboxScript.swf' / >
< arg line='F:\FLEXWORKSPACE\FlexPro\CheckboxScript.mxml' / >
< /exec >
……
……
Step 5:
Run the application
Step 6:
You get output like below
You select Playing Cricket and click OK button.
The message will be displayed in Label 2
