I am trying to pop screens (per the API example) and am getting mixed results. Can someone please help me out. This seems to be the last issue I need to overcome with the player.Function popAndShow(screenArray As Object) As Void screenToClose = screenArray.Pop() screenToShow = screenArray.GetEntry(screenArray.Count() - 1) screenToClose.Close() screenToClose = invalid screenToShow.Show()End FunctionAssume a simple case where I have screen A that is a home screen and it can invoke screen B. The user wants to close screen B. Screen B should close, screen A should now be open. I do this, and I have an "exit while" statement in my event handler in B. Yet, while I can go from B to A, I can not then go anywhere else as I have lost focus and can't get it back. Can someone help me see the light please?screen a = createObject("roPosterScreen")screenArray = createObject("roArray", 1, true)screenArray.push(a)...while truemsg = wait(0, a.getMessagePort())... can't close this screen so just do what the user asks when the user is here.... user wants screen b so...b.show()erstwhile...screen b = blah, blahscreenArray.push(b)while truemsg = wait(0, b.getMessagePort()) 'port is the same as a'sif msg.isScreenClosed()popAndShow(screenArray)exit whileI find that the above will take me back to the screen I want to go to. However, it will just not give me focus back. Can someone help please?

Looks like I finally figured out how to make this work. I had a method that took care of all this and, for whatever reason and even when I could see the order of closing was right, I was just not getting back control. I created something of a factory controller which manages all this for me now. As I'm tying everything back together, it seems like it works much more smoothly with that factory in the middle of everything.

you should share how you got this to work, could be useful

Actually, I came back in to say that I did not get it to work and there could be a problem in the Roku which is driving me crazy.I now have a factory object that takes care of anything and everything nicely. It opens and closes smoothly on any screen. But, consider the following scenario...Screen a is a selection of videos (which may be deep in a tree). You can navigate up and down the tree fine. Then, pop another onto your tree (play the video) and create a roVideoScreen. Interrupt it. Go back... That will work fine and you'll get back to screen a if you pop and show.However, let's now assume the user does not interrupt and go back but instead plays another video and interrupts it and then decides to get out of screen a altogether (to see another category perhaps). If I play twice and interrupt twice, I can continue selecting and playing on screen a. But, if I decide to leave screen a, the screen prior to it will not open and I'll get a blank screen. This is despite the fact that the same controller is using the same methods to close screen a that it does every other time a user closes (without getting all the way to playing a video for instance). To demonstrate this in a chain form...Home Screen ----> roPosterScreen one ---> roPosterScreen two ---> roPosterScreen threeI can go up down and sideways on all those screens with no problem. Now...Home Screen ----> roPosterScreen one ---> roPosterScreen two ---> roPosterScreen three ---> play the videoI can still go up down and sideways on all screens (as many times as I like) but do this and it all goes to hell:Home Screen ----> roPosterScreen one ---> roPosterScreen two ---> roPosterScreen three ---> play the video ---> interupt video ---> pop and show roPosterScreen three (iterate as much as you like) <---- go backNow you'll get a blank screen and the player is dead.This has cost me a lot of hours of my life. If someone can point out what I could be doing wrong, I'd love to hear it. It makes no sense that the code that manages all this can do it all fine and will have absolutely no issues with any combination of screen pops until you play and interrupt videos a couple of times.

In reading my post, to be as accurate as possible, the ONLY time it dies is if I play two or more videos from any one poster screen and then try to go up the chain. If I only play one, or I go up and down the chain in any other combination, there's never a complaint. But, play two or more videos and try to go back and the Roku goes dead.

Still not solved, but I have a hanky-janky patchwork that screws up the way I want my app to work but at least I can guarantee that it stays running now. For whatever reason, you can't play twice and then pop back to a screen prior to one that has your posters for video selection (at least I can't). So, I'm now popping twice any time I see the player close to take the user back to the third screen. Then I force it to reload the 4th screen which the user plays videos on. Again, if I leave the user on the 4th screen they can select and play as many videos as they like. Then when they try to go back (unlike every other case) they get to look at a black screen. If anyone else has this problem, there's how to solve it for now. LOL.I can't keep messing with this any longer. I literally went Friday and Saturday without sleep and finally went to bed on Sunday at midnight, all over this. I even missed a plane flight (I have a really pissed off girlfriend now) and I still don't have it solved.I will come back and show you how I got good quality screen flow with a factory tomorrow after I have finished tying this app back up, now with a two screen pop at the end of the chain.

One of the users here posted an emacs minor-mode. I'm using it. If I had good command of Emacs, it would not be so bad. But, try cutting and pasting in that thing. And, if you are a shortcut lover, forget about it. I can't tell you how many times I hit ctrl v and wound up down a the bottom of the page. Or select, cut, select text to copy over, paste and the text you cut does not show up... it makes a copy of the text you just highlighted. Unix freaks.

BTW, Kevin, I know now that there's no problem with using one thread and in fact that makes a lot of sense. In lieu of any discussions regarding threading, how about a troubleshooting section of the typical problems (if you're seeing this... you may consider trying this). Nonetheless, it works, it's cool, it's even fun despite some of the tools I'd like to have. I'm sure that's just around the corner though.

Cheers,
Al

It's just a matter of bypassing your ingrained conceptions about how cut and paster are supposed to behave. Which is hard, I imagine. I'm lucky enough to have used vi/vim for a long time.

The thing with vim and Emacs is that you can be amazingly productive with them when you know all the commands/shortcuts or define your own. If I have to move a hand from the keyboard while coding, my editor has failed me.

BTW, it would be nice if someone opened up an open source project on the SDK. An eclipse plug in or perhaps a java API that outputs members as BrightScript or xml instantiation or anything with an IDE. About 90 percent of my problems were mispellings that are not caught until compile (as well as type declarations ";" at the ends of my calls... lol). Plus, writing in Emacs (better than nothin') is miserable for me.

It's probably not as feature rich as you're actually talking about, but it's a good start:
