@SGaist No. Both computers have same codec set.

@RobM said in QQmlImageProviderBase::ForceAsynchronousImageLoading causing application crash: Which portion are your referring too? Sorry, I meant the top of the stack, my bad - from #11 to #1 By double deallocation do you mean a double free()? Yes. A double delete probably, but more or less it's the same thing. Specifically #9 is rather suspicious (due to #5). It appears the crash happens when cleaning up the QString's data, which, as it being rather tested and I know it works, suggests that this data was already freed someplace else. Please provide the code around the requested region.

Although @Chris is very much correct, as is his usual style, I hope you are not left with the impression that you can't use C++ at all inside the library, though. His point concerns the symbols alone. You could use as much C++ as you want inside (i.e in the private part/implementation(s)) the library, you just need to export a C interface for it to be compatible between different compilers.

Thanks, QTableView is definitely what I need. And I will look at QLayout and friends for my resizing needs.

i have added my 2¢

Hi and welcome to devnet, If working with video, recent versions of Qt allows to use custom GStreamer pipelines so why not take advantage of that rather that doing things manually ?

@eyllanesc Thank you for your helping. That solved the display problem.

@Kekz A 32-bit has 4 billion range. Your horizontal screen resolution is, say, 1,920 pixels. So 2 million bits available per pixel the user can see. I don't think losing precision will be an issue :)

Thank you @JonB for your explanation I understand the problem right now. @Pl45m4 I created two seperate classes, because those classes have more functions to them and I didn't want to overload a single class with multiple functions. Perhaps I should refactor my code a bit more and delete unnecessary stuff. Thank you for the suggestion :P

@SGaist Oh sorry, I was using UINT but made it simpler for the post, forgot to set lower-case, I edited post for clarity. I think you're right, the conversion was failing and was returning QString, instead of int (UINT for my case). I checked it out and decided to apply it, so I ended up converting everything to bool, since I only needed 0 or 1, and my problem is solved. bool v = settings.value("key", defaultValue).toBool(); if (v.canConvert(QVariant::Bool)) { qDebug() << QString("Hi"); } Thanks everyone!

@mrjj thank you

@Baturtoraman Start by setting environment variable QT_DEBUG_PLUGINS=1 and then running your program. See if that gives you more information about why it seemingly cannot find the driver in Release build though it can in Debug build.

Hi, Could you try this? myTextBrowser->document()->setMaximumBlockCount(iMaxValue); You have to adapt it to Python as it is C++.
