navigateToWindow() is a package-level ActionScript function that encapsulates all of the logic around opening a browser popup window from within Flash.
The test/patternpark/net/NavigateToWindowTest.as file demonstrates how you might use navigateToWindow(). This project was build with Project Sprouts. To run the test suite, install Sprouts and then run ‘rake html’ from the location where you pulled this project down.
For background on this project, you can check out my old post Workaround for Safari Blocking Flash Initiated Pop Ups.
