14.5. FileSystemComboBox
The FileSystemComboBox is the last of the file system components. It accepts the same directory property as the other file system components that we have previously covered. It will always allow you to see the full path from the file set as the directory property back up to the root of the file system. To demonstrate this, add <mx:FileSystemComboBox id="fscb" x="384" y="419" width="240"/> to the Chapter14_Comps.mxml file. Next add fscb.directory = file; to the end of the showFileDetails() method. This will set the directory property of the FileSystemComboBox to the selected folder of the FileSystemTree. The results can be seen in Figure 14-9.
