General and Desktop

Yep, it's in my bookmarks :) Maybe the only helpful discussion about this protocol. There is an open source implementation, which tries to encode/decode but written with .Net. Further features can be observed from that project but first, I need to be able to communicate over IP layer. This will be a new Transport Layer protocol hence not implemented in Qt. Still struggling to find a way in the QUdpSocket implementation in qtcore source package. My next shot will be system socket libraries or boost::asio.

Hi and welcome to devnet, You have the details of their handling in QUIP15

Hi, You have to explicitly install it. That module was deprecated a long time ago.

From (very old) memory, it think the one having issues was OS X.

Can you reproduce that with a minimal example ? If it only happens in Plasma, you may have unearthed an issue there.

@JulienMaille said in processEvent() differs between Qt4 and Qt5: My question targets processEvent() not Qxt I'm using QxtSignalWaiter to wait synchronously for a signal, with no issues and, as stated in another topic here, it worked fine until Qt5.9/5.10. Then it started to get stuck in the processEvent() call and generate other erratic behaviors. mhhh... anyway: fix your code and make it async.

@Wapiti said in QProcess emit exit signal too earlier: QString launcher = "C:/Program Files/D-BOX/Gaming/Assetto Corsa/ACWithLiveMotion.exe"; QProcess process; connect(&process, SIGNAL(finished(int , QProcess::ExitStatus )), this, SLOT(SessionFinish())); process.start(launcher, QStringList()); void MainWindow::SessionFinish() { qDebug() << "session is finish"; } Are you sure that you did not use local variable? if process is defined in the header, the connection should look like this? connect(process, SIGNAL(finished(int , QProcess::ExitStatus )), this, SLOT(SessionFinish()));

I went as far as editing QVTKRenderWindowInteractor.py that ships with VTK. The original file is using either QWidget or QGLWidget as its base class, default being QWidget. I changed it to use QOpenGLWidget. I tried with the 3 different base classes: exact same behavior.

Thanks to both of you. I believe my issue has to do with processEvent() and not the connect. I will open another topic

@Christian-Ehrlicher thanks for the correction. @suslucoder it's showing old search items with different color because you have set it's background color in last search.. It's better to set all with default color and matched items in highlight colour for each search

@suslucoder There is no scrollBar by default but you can increase the space for your QLegend https://doc.qt.io/qt-5/qtcharts-legend-example.html#detaching-and-attaching-legends Or you put a custom legend in a QScrollArea

@savithaKM said in How to create apk file for Desktop GUI: I mean, I need to create an app(for my GUI) where it can be used in any other desktop where Qt software is not needed to be installed I am not sure to right understand your problem, so I try to rephrase it, feel free to say what's wrong, what's right: you have create a GUI Qt project for desktop you want to distribute this application What is the target operating system: Linux? Windows? macOS? To deploy your application there are many resources on Qt which describes what you have to do: for Windows: use windeployqt.exe cf. https://doc.qt.io/qt-5/windows-deployment.html for Linux: you have to do more "by hand" cf. https://doc.qt.io/qt-5/linux-deployment.html for macOS (I never do it): follow https://doc.qt.io/qt-5/macos-deployment.html

@Qt_User444 said in Retrieve the file path using Qprinter or Qpainter class.: Since it is mandatory that the save dialog should be opened by calling the QPainter constructor Why should QPainter open any dialogs?! It's job is painting, not showing any dialogs... But if, for some strange reason, you really need to do so then subclass QPainter and add your own constructor.

Namespaces are not Qt specific. It's a C++ thing. Qt by default doesn't use them for classes, but puts globals, enums etc. in Qt namespace. You can also configure Qt to put everything in a namespace if you experience name clashing. As for whether or not you should use namespaces in your own code - that's up to you. They are not required. Some projects use them, some don't. It's polite to put your code in a namespace if you're making a library that gets included somewhere, so that you don't pollute somebody's code. @James-Mark-Chan said: is there a one line way to indicate all items in a file are for a particular namespace? No, namespaces in C++ are enclosed in braces. File is not a particularly interesting data unit in C++, apart from some minor scoping details. A more common scope is a translation unit which can be composed of several files.
