General and Desktop

@Ketan__Patel__0011 OP states btn_close does not emit the clicked signal at all.

@JonB QPushButton does allow both. @TomNow99 you can reimplement the handling of dropped data to fill the model with want you want.

Hi and welcome to devnet, The final sink must be named: "name=qtvideosink". See the setMedia example.

Hi, Yes you have to, it's explained here.

One more "gotcha" Dragging widget to scratchpad DELETES it from the form !

Could "edit buddies" in QtDesigner help with "matching " the widgets format ??

Thanks SGaist, will tag as solved.

If you chose a CMake project, a CMakeLists.txt file will be used. You have to choose qmake as build system to get a .pro file.

@Pablo-J-Rogina i changed the class name aswell to match :) Socket class socket object

@JonB I have also tried with setFilterFixedString and the proxymodel still doesn't filter. I don't need to set filterRole as it is display role be default. As I understand the docs, I shouldn't need to subclass the proxymodel for such a simple use case. It should be working out of the box. You are right I misspelled. It should be fifth column but the code is correct. Let me share a screen shot of the table I'm trying to filter.! [image: d56681df-7ee5-4aa8-ae7c-1040851de04c.png]

@kuzulis said in QSerialPort readAll() does not work with 5.14.0 anymore PS: And yes, you don't need in QThread::msleep(3), because it has not sense (because the sleeping already does by waitForXXX() methods). Ah, ok. I guess bool com::waitForReady(int timeout) { waitForReadyRead(1); QElapsedTimer elapsed; elapsed.start(); while (bytesAvailable() == 0 && elapsed.elapsed() < timeout) { waitForReadyRead(1); } if (elapsed.elapsed() < timeout) { return true; } return false; } is the "correct" solution then. Update: Just for the sake of completeness, here is the patch for my program: https://github.com/BrillouinMicroscopy/BrillouinAcquisition/pull/135

@JonB You were right about being surprised. Because it wasn't returning Qt::ItemIsAutoTristate. I'm overriding the setData()-function in that model as well and apparently the issue came from handling the checked-state in there. I'm not yet sure how this resulted in this behavior. So thank you, the issue was NOT with the flags.

I got it fixed, thanks to @Christian-Ehrlicher! I almost did not try your suggestion because I thought I knew very well where the warning comes from. But it turned out that I had missed a setQuery() call that was lacking its second parameter (the database connection to use).

@mirro What is your question/problem? That link shows a number of examples.

Hi @Christian-Ehrlicher , Thank you for your comment. Perfectly understood. Have a nice day, Davide

@simone-malvezzi Always a good idea to state your Qt version when asking a question like this! :)

@terryGGG It doesn't crash every time, the crash possibility may lower than 0.1%. I don't think anyone will be able to solve this for you from what you show. And you do not say what version of Qt you are using, which might be relevant. Write yourself a standalone program, as minimal as possible [~20 lines?], which just does your code, 10,000 times in a loop. Make the command something simple & harmless, say dir or echo hello. Does it crash? Does it matter what the command is? If you do get a crash: get rid of both cmd->waitForStarted(); cmd->waitForFinished(-1); and replace with the QProcess signal/slots equivalent, so no waitFor...() calls, which can be "dodgy", especially potentially under Windows. Does that crash?
