General and Desktop

Yes, I saw this one pager, but is describes more the other features instead of the request and response feature. I hope he will create a new blog soon with some small examples how to use.

Maybe I expressed myself incorrectly. By native I meant that uses the WinMain function as an entry point, for example. Something like the code in the link I've poste. But If you can provide some example code on HOW I can use Qt and the win32 APi and Direct X 11, I'd appreaciate it. I have not been able to find ANYTHING online. Just a simple open a window and draw a circle or something will do. I want to know how con configure the .pro so that it will find all the appropriate libraries and the code will compile.

@saeidparand that is good to hear :)

@jonb solved but It was not about the level of access. I set Run Environment in System Environment in QT Creator. thanks for your suggestion.

@sgaist I got it, I needn't have implement operator for ExpAnalysisResult, just delete it.

@cobra91151 OK. Thank you very much. Yes, I tried this solution before.

@jonb yes i need to process the locked state of the database because it can potentially be opened from another application as well (in a nutshell, these two apps can talk to each other). i actually downloaded the files and compiled them. two posts above i show the code which i'm using but it doesn't return anything related to sqlite being busy or locked. is the code actually correct?

@christian-ehrlicher said in Header of first column overlaps the expand/collapse indicator in QTreeView: But how much size? This space depends on the style and the tree depth. The default indentation can be acquired by calling indentation() and the depth, by looking at the picture, is fixed. If not you can still manually set column size on expanded/collapsed signals. Or you could just set it to automatically adjust to contents.

hi just in case. [image: 5GRrW3.png]

sure you can do that, but you better use locking on writes, and conditionally on reads (such as if the reads are not atomic or access multiple elements in one operation). locks are not just good form. they are necessary when you have more than one task accessing the same memory concurrently. Also, you should probably use data() method instead. So yeah, you can put a wrapper around QSharedMemory that does locking...I would.

@amazonasmann said in QVideoFrame does not deliver correct startTime() and endTime() / QMediaPlayer issue: Now I have to visualize both informations in the same frame. Well I guess you had better throw out the idea of using the Qt multimedia system and write your own decoder and displayer. I've done it in Qt4 where we had to support custom codecs delivering video over wireless links. decode your frames manually into a suitable pixel format buffer and then use an x11 video extension to map that pixel data into an application window.

Hi and welcome to devnet, OpenSSL 1.1 support is only available since Qt 5.10. OpenSSL 1.1 breaks both API and ABI compatibility with regard to 1.0. You can't just replace one with the other.

@surendar-dharani there's no need to do necro-posting when you are already getting answers on your thread.

@feistykittykat Don't know if I'm allowed to bump this bad boy up. Been struggling to use PVRVFrame or something similar to get openGL found on my machine, but I have no idea how to set it up for QT. Still not even sure if that's the source of my problem.

@mrjj Thanks my friend your answer has helped me.

@pablo-j-rogina jup, I agree, my initial statement was incorrect
