When you construct an application, your design will likely often call for a pop-up or editing window. Flex offers a convenient mechanism in the pop-up manager to help you create, delete, position, close, and destroy windows. When you're choosing the type of pop-up window to add to your application, it's a good idea to plan ahead and first determine what the purpose of the pop-up will be and what you'll need to do in the pop-up window.

An alert issuing a simple "Hello World!" message. Click OK to close the window.

This chapter covers the following topics:

• Creating a pop-up window
• Sizing and positioning pop-ups
• Communicating with a pop-up window
• Closing pop-up windows
• Using alerts
