      I have since found out that grabWindow doesn’t work under Wayland. So I either have to find another way or resort to X11 again.

      @Christian-Ehrlicher said in Dynamic XML documents instead of `.ui` files in Qt:

      @brainchild The uiloader is just a way to load xml files which in 99,9% are processed by uic and compiled directly instead. So adding this complexity to pass a DOM instead a simple QIODevice for the max. 0,1% use case is fine in my pov.
      Esp.since there is no need for a DOM and QtCore don't have a DOM class at all - QXmlStreamReader is perfectly fine for this simple task.

      The XML module has a DOM representation. Why would it not be sensible for a version to be provided of load() that processes a DOM representation from this module?

      Qt integrates very well with OpenGL so I am unsure what you think you would be missing ?

      That said, another possible way to do what you want could be the Graphics View Framework.

      Hi,

      That's because these classes are no widgets, there are used to build the UI.

      In you code snippet, you would use self.nextui.hide() to hide the widget that was created with the help of Registration.Ui_Registration. That is the same for all the widgets you created that way.

      @Aahi You don't have to use this old connection style. Remove SIGNAL and SLOT words.

      auto window2 = new MainWindow(); connect(ui->pushButton, &QPushButton::pressed, window2, &MainWindow::some_slot_that_you_have_in_MainWindow_class); some_slot_that_you_have_in_MainWindow_class() { ui->checkBox->setChecked(false); }

      Something like that

      @JPolo said in Unable to compile when using QCustomPlot:

      I use Qt Creator 4.15.0 based on Qt 5.15.2 MSVC2019

      That is not necesserilly Qt version you're using (this is the Qt version used to build QtCreator).
      What Qt version did you install?

      What is the first error message?
      Did you do what the tutorial suggests: "To use the shared library in your application, set the define QCUSTOMPLOT_USE_LIBRARY before including the QCustomPlot header."?

      @andyP said in After using my Qt desktop application for a while and also using other applications simultaneously the stylesheet of my Qt desktop application changes.:

      But after a while using my application and other programs simultaneously the stylesheets changes.

      I don't think anyone can diagnose this.

      However when the stylesheet changes the button is instead shown as light blue when starting:

      If you replace the first stylesheet rule by the second one you will lose the first stylesheet's green foreground/background, if that is what you mean. Then the light blue presumably comes from some other applicable rule you have.

      Hi,

      On macOS you have that option integrated through Sidecar.

      On Windows, there are several possibilities existing.

      Do you really want to re-implement that ?

      @Yalimyulad said in Post installing Qmake for new devices:

      Is it possible to somehow copy the Qmake I have built from raspberry pi to my desktop?

      Nothing is physically stopping you, but it won't work.

      qmake is created and specific to the Qt FrameWork/Compiler used for that framework.
      The compiler on your pi is not the same as the one you would use for cross compiling

      If you want to really cross compile for the Pi , you will have to jump through some loops.
      There are some guides out there for example this wiki entries

      @JDePedro
      Ok. I found the cause why I was not getting anything QML related from the tool. My widget is not in the exe file but in a DLL so I had to specify the dll instead.

      But the list of files the tool is getting is huge compared with the one I got by doing the process "manually" and includes most of the .qml files. So my doubt is, do we need to deploy all this files with my application? is not enough with the dlls???
