Hi all, I ran into an issue with keyboard focus which I don't understand, and I don't see detailed in the docs anywhere.
We have a site that has games in it as well as forms, so sometimes we want game-style key handling and sometimes we want the form style, where tab or mouse clicks change focus. In many of our games you need to use the keyboard and mouse, and it seems as though every time the mouse button is pressed inside our game area (a Flex Canvas), stage.focus gets set to null, so the keyboard event listeners attached to our Canvas don't get called. My current hack to fix it is to listen for FOCUS_OUT events from the Canvas and set stage.focus back to the Canvas. That seems to work, but I wonder: 1) why Flash (or Flex?) is setting stage.focus to null when I click on my game Canvas, and 2) how to make a component (my game Canvas) such that I can programmatically set it to be focused or unfocused and disable the mouse button -based focus change. It seems funny that I have to keep re-asserting the focus. I tried listening for MOUSE_FOCUS_CHANGE events and cancelling the default action of them, but those events did not fire when the focus was changed to null. Strange. Another factor is that sometimes our games are loaded from other .swf files, and then the game Canvas can't access the stage because it would be a sandbox violation. So it seems like I can't just attach my game key listeners to the stage directly. In fact this makes me wonder if my stage.focus thing isn't going to fail as well... I suspect I need to make my game canvas implement IFocusManagerComponent or something, but before I spent too much time experimenting I wanted to see if anyone already knew the Right Way to handle this.
