I've never used a protoFloatNGo, so my comments might be irrelevant to
what you're trying to do or come off as a more hackish way of doing
things, but I've found it pretty simple.
1. Make a new clView layout for your subview, add it to your project,
and make it a linked subview to your main app. You *won't* be able to
declare it to your base app, but don't worry about it.
2. I'm using mine as a window for instructions, so I've called mine
textHelp. In your base app, in NTK you should have "linkedSubview:
textHelp" over in the upper left box.
3. To access it from your base application you use something like:
textHelp:open();
4. To add text instructions (in my case) to the linked subview you can
just do something like:
SetValue (textHelp.helpText, 'text, currentText);
where helpText is the protoStaticText in the subview, and 'text is the
text slot in that. currentText is where I can assign whatever text I
need at a particular moment (depending on which instructions need to be
shown at any particular time). I have all of the text I need to show
defined in my project's main text file as constants, and I just call them
up from there depending on which instructions I need to show. For
example, in my text file I have:
constant kHelp1 := "These are the first instructions.";
constant kHelp2 := "These are the second instructions."; (etc.)
So if I need to show kHelp2, I'd do like:
currentText:= kHelp2;
textHelp:open();
SetValue (textHelp.helpText, 'text, currentText);
And the floating layout will appear with the text "These are the second
instructions." (or whatever the actual instructions happen to be).
Just one way of doing it--perhaps not the best, but it definitely works!
