Solved iOS not receiving touchEvent at app start up
-
@SGaist Hi & thanks! QWidget (sort of). I'm using none of the QWidget stuff as I have my own OpenGL/GLES code (not much of an abstraction, i like it that way as it's game code!) So I'm using QGuiApplication and QWindow as well as Qt OGL surface abstractions.
I don't use those classes directly in my code, there's a very thin abstraction layer so I can do work that I need on all platforms, notably setting up app specific persistent storage areas and kicking a derived store/restore function.
I'm trying to whittle the code down to a minimum amount required to reproduce the problem.
I'll update on Monday.
I'm no Qt noob BTW. I've done a couple of platform ports and was active at Qt Centre from about 10 years ago under a couple of different aliases. If I have to dig into the guts of Qt that's no problem.
-
@SGaist I think this ... https://bugreports.qt.io/browse/QTBUG-53874 is related.
-
Might be, note that both platforms have different backend.
Could you also test with Qt 5.7.0 ? That way it could help pinpoint whether it's something new to 5.7.1.
-
@SGaist I noticed that. That is the difference between platform plugin ios and cocoa.
I still haven't got to the bottom of the problem but instead I switched my "platform_window_opengl" to use QOpenGLWindow. That code path fixes the problem. I still don't need to pull in the widget library (don't need/use it) so for now I'm happy.
When I get a chance I'll dig into the implementation of QOpenGLWindow vs QWindow (with own context creation) to see what functionality is missing.
Does it still sound worthy of bug repoting to you?
-
Yes please. Even if the recommended way to build mobile UI is QML, it's better to have that kind of stuff known.
-
@SGaist I've tested with 5.7.1 and 5.8. I'm very sorry but as a solo developer I don't (at the moment) have time to run those sort of regressions.
-
@SGaist I've got weird and horrible news.
I let my iPhone update to 10.2 (from 9.3) last night and now the problem doesn't occur!
These sort of things make me go... ARGH!

hi,
now i start qt basic programming,can i use c sharp .dl
l in qt programming ? -
@matthew-kuiash sure thing, I understand. Ok, so there was something going on with 9.3. I think it's still worth mentioning.
@Rameshguru Please don't highjack other people threads with completely unrelated questions, open your own threads.

@SGaist Done https://bugreports.qt.io/browse/QTBUG-58014
Thanks for your help with this "heisenbug"

Since it's C# related, go to General and Desktop. On the top left there's a big blue button call
