Navigation Issues

[cncb]

1) It appears that it is not possible to have multiple popups open. If a popup launches another popup, the first one closes. I have to have the screen respond to a callback when the second popup closes to re-open the first popup which looks kind of odd. Any way around this?

2) If I activate a second screen from the main screen in my plugin (both defined in the plugin) the main screen seems to not be added to the navigation history. That is, if I hit escape to go back one screen it jumps back to the main screen/menu?

For 2), you should be able to capture the Escape/Exit keypress in OnkeyDown and get your own code to reactivate the original screen. Then just return true from OnKeyDown to let the API know you've processed it.

No, that is the way it is intended to work. ie, chain them together, one popup can open another popup, then reactivate itself if need be depending on a callback.

That is correct. There is only ever one active screen. As imilne suggests, you can programmatically switch to back to some other screen rather than the main menu if you need this behaviour.

I know the API isnt perfect. I just wrote what I needed, and ultimately that same functionality was exposed to plugins. NextPVR was created from scratch, very quickly in about 6 months, and in some areas I wish I'd done things slightly differently. Hindsight is 20/20 and all that. I do take suggestions though, and will try to incorporate them, as long as they can be done without breaking compatibility with existing functionality.

Thanks - this works well.

I definitely cant claim the API I created is perfect. I just wrote what I needed, and ultimately that same functionality was exposed to plugins.

I was not suggesting there is anything wrong with the API and it is working well for me once I figure out how things are. In fact I was able to put something together relatively quickly which is nice given my track record of wasting too much time developing plugins for HTPC software that ends up being abandoned (Beyond Media, TVedia, and now SageTV).
