![]() It may be because I'm working with "mostly Qt 4" code and compiling on Qt 5 that things are being a bit odd but this method now works, so I've not investigated further. In GUI programming, PyQt provides robust and cross-platform SQL database support that allows you to create, connect to, and manage your databases consistently. SQL databases are everywhere and have great support in Python. Each method created its own app object (QCoreApplication for headless, QApplication for GUI, as the docs show) and then running the app. Building applications that use an SQL database is a fairly common programming task. I had to use the command line arg to then choose one of two methods to run. The example there didn't "just work" for me, either! So, following posting a question here, further research lead me to the following QT5 document that explains the "approved" way to start up with or without a GUI depending on command line options: There was a workaround - export QT_QPA_PLATFORM='offscreen' - but that's not a command line option, your user is expected to do it, which isn't nice. When running without an X display (any value for DISPLAY, not just localhost:10.0). The example by lpapp above didn't work for me, as I got qt.qpa.screen: QXcbConnection: Could not connect to display localhost:10.0 v, -version Displays version information. Process the actual command line arguments given by the user QCommandLineOption guiOption(QStringList() << "gui", "Running it via GUI.") A boolean option for running it via GUI (-gui) Note that it is only available from 5.3, but the migration path is pretty smooth within the major series if you still do not use that. The wizard will guide you through the setup of the project.Yes, you could use a "headless" or "gui" option for the binary using QCommandLineParser. Qt produces highly readable, easily maintainable and reusable code with high runtime performance and small footprint and it's cross-platform. The quickest way to create a project is using the “Auto Test Project” template, which is listed in the “Other Project” group of the “New Project” dialog. The Qt framework contains a comprehensive set of highly intuitive and modularized C++ library classes and is loaded with APIs to simplify your application development. The idea behind Qt Test is that each test case needs to be an independent executable and needs its own project. GUI unit testing with Qt Test – part 2 – advanced testing.GUI unit testing with Qt Test – part 1 – introduction.C++ unit testing with Qt Test – part 2 – advanced testing.C++ unit testing with Qt Test – part 1 – introduction.This is the first post of a series dedicated to Qt Test. That will involve creating a project, defining the unit test and using the different macros available to test code. In this tutorial I am going to explain how to use Qt Test for testing a C++ class. It is part of Qt, which means it includes features to test Qt GUIs and other Qt elements like signals, but it can also be used to test plain (no Qt) C++ code. Qt Test is a framework for C++ unit testing. Full qmake project and C++ source code are provided. Hi, I just installed qt 6.0.1 trial version, trying to work with vs2019. ![]() A working example is discussed and analysed in detail. Qt GUI Application Wizard in Visual Studio 2019 does not enable the Finish button. ![]() This tutorial is an introduction to C++ unit testing with Qt Test. First, please check if you have installed the correct packages providing those modules.
