I have a frame that has "keep display from previous" turned on and it mostly works, but when I try to embed it in another frame as a subapp it should still preserve the background from the main frame that hosts the subapp, right? Only it doesn`t ;_;
Are there any plans to address this? It would make making menus, inventories, cutscenes and similar a breeze!
I believe it's because the sub-app doesn't have a "previous" frame to keep the display of - it doesn't know anything about the background of your main application.
Being able to do this automatically would be handy, but you can work around it by using the Screen Capture object to save an image just before the sub-app loads, and to load that in a Picture object at the back of the subapp. It sounds awkward, but it should look seamless. This is the technique I used here - http://www.youtube.com/watch?v=qpCXGdKJFn8 - pause menu appears around 1:40-1:50.
There's also an oddity in that if you have a Windows control such as a list box in the frame of your subapp, then the background will be preserved if you also have "Keep display..." on. But this is prone to strange effects when you switch away and back again.
Fair enough. Still, it`s unpleasant when "Keep display..." doesn`t work as it says (even if it`s logical when explained).
I`ll have to use a workaround I guess.
For anybody else in the future that finds himself in a similar situation and stumbles upon this thread while combing the forum, here`s a similar situation: Dines subapp.
