You can change it in the save event as the user could key anything in the save
dialog and I do not know of any way to hook the key press event in that dialog.
This is some 'old' code to change/force the ext, I originally got idea from
someone's posting, and change it a bit:
import flash.events.Event;
import flash.filesystem.File;
import flash.filesystem.FileMode;
import flash.filesystem.FileStream;
private var documentsDir:File;
private const defaultExtensions:String = "ForcedExt";
private const extensionList:Array = ["ForcedExt"];
public function localSave():void {
documentsDir = File.desktopDirectory;
documentsDir.browseForSave("Save As");
documentsDir.addEventListener(Event.SELECT, localSaveHandler);
}
function localSaveHandler(event:Event):void {
documentsDir.removeEventListener(Event.SELECT, localSaveHandler);
var pathArray:Array = File(event.target).nativePath.split(File.separator)
var originalFileName:String = pathArray.pop();
var newFileName:String = checkExt(originalFileName);
pathArray.push(newFileName);
var newURI:File = new File("file:///" + pathArray.join(File.separator));
var stream:FileStream = new FileStream();
stream.open(newURI, FileMode.WRITE);
// Replace this with your actual file write routine.
stream.writeUTFBytes("Your file contents");
stream.close();
}
private function checkExt(fileURI:String):String {
var fileExtension:String = fileURI.split(".")[1];
for each(var it:String in extensionList) {
if (fileExtension == it)
return fileURI;
}
return fileURI.split(".")[0] + "." + defaultExtensions;
}
