Levure confusion

Post by amn » Sat Feb 02, 2019 8:37 pm

Hi,

My levure app (once glx…) starts properly in the IDE, but the standalone throws no errors that I can see, remains running, but never becomes visible onscreen. My rudimentary logfile shows the same entries regardless of Ide or standalone. Is there anything else I can check to see why this might be happening?

Should the application state still be "loading" at this point? Anyway, thanks for any tips that might be forthcoming.

Hi @Allen,

Some questions:

1) Did this work before?
2) If it did, what changes have you made since the last time it worked?

Regarding the application state, once "OpenApplication" finishes running then levureApplicationstate() should return "running". If it doesn't then an error is being thrown. Quick way to check - at the end of OpenApplication put an answer dialog that let's you know the code got to the end. Or put all of the code in OpenApplication into a try/catch block.

Hi,

Thanks for thinking about this on a Saturday. My application was working, with my last additions being turning the "window_manager" helper back on, and refactoring what had become a very disjoint set of handlers performing my startup sequence. Its much cleaner now, but it did introduce the issue I'm seeing (it is a windows standalone). I will try your suggestions, and I really appreciate all the glx/levure work you have given us.

In the message_watcher.livecodescript file you will find the code that manages windows. Because of a bug in versions of LC earlier than 9.0.3 (still in development) the stack window is hidden in preOpenStack. In the windowManager.livecodescript file the window will be shown again in the openCard handler. Does your stack trap the openCard handler? If so, just pass it and the window should show up.

Hi,

Thanks for the insights. I included try/catch in app.livecodescript and do not seem to be getting errors at that level. I could not locate anything of my doing that is trapping or even handling/passing openCard, but something must be. I am ok again after disabling the window_manager helper for now, and will check again at 9.0.3. Just enabling the helper for me on windows executables, and not overtly using it, exhibits the screen not shown.

I must admit I felt some pressure in writing this response, to get it finished before 9.0.3 is released. I'm afraid to look.

Thanks again,

Allen Morgan

If you wanted to get to the bottom of it you could sprinkle some messages in the `windowManager.livecodescript` `openCard` handler to see if it ever gets called. There is an `if` statement in there so you could verify A) if `openCard` is making it to the `windowManager` script and B) if `set the visible of the owner of the target to true` is being called.
