I am a web developer. It’s been over 10 years since I’ve done serious desktop application development. So when I fire up Flex Builder to write my first AIR application, it takes a while for things to start coming back to me. One of the things that is only now starting to come back is Event Driven Programming.
This past week I decided to start working on a small project to scratch a personal itch. The project itself fizzled but I learned something none-the-less. I learned how to create custom events in Flex 3.
The project required selecting a file for processing. Flex 3 has a control for actually opening the dialog box and selecting the file but no control that shows the button and the selected file name.
