所谓的断言，其实很简单，它是一个宏定义，接受一个布尔值，当判断的语句为真时，不做任何操作，如果判断的语句为假，那么在 debug 模式下程序运行到该地方会自动断下，并弹出一个系统消息 In this example, assert is used to abort the program execution if print_number is called with a null pointer as attribute. This happens on the second call to the function, which triggers an assertion failure to signal the bug. This PR asserts those dynamic calls. Once we bump Qt to at least 5.10 these can be refactored to use the `invokeMethod` overload that allows connecting to lambdas or member pointers, which are compile checked. For reference, one of the overloaded versions is https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-5 . Hi there, Please forgive me if this is a well known issue, I've searched the forum and couldn't find anything, although I can't imagine I'm the first one this is a problem for. 1 qt_message_fatal qlogging.cpp 1681 0x6705a78b 2 QMessageLogger::fatal qlogging.cpp 795 0x67058fb2 3 qt_assert_x qglobal.cpp 3078 0x6704c6e1 4 QCoreApplicationPrivate::checkReceiverThread qcoreapplication.cpp 533 0x6742e9be 5 QApplication::notify qapplication.cpp 2970 0x64101974 6 QCoreApplication::notifyInternal2 qcoreapplication.cpp 988 0x6742cd16 7 QCoreApplication::sendEvent Useful to assert until some condition is satisfied: def view_updated (): assert view_model .

Once we bump Qt to at least 5.10 these can be refactored to use the `invokeMethod` overload that allows connecting to lambdas or member pointers, which are compile checked. For reference, one of the overloaded versions is https://doc.qt.io/qt-5/qmetaobject.html#invokeMethod-5 . In Qt code unit tests are almost always used to test a single C++ class QVERIFY is similar to ASSERT in other test suites. Similarly, lines 19 to 27 provide another test, which checks a setter, and a couple of accessor routines.

I'm still trying to discover which thread crashed and how to get a backtrace. The most suspicious thread is thread number 2, at qvector.h: Qt 4.8 was the first version of Qt that started to make use of some of the new C++11 features in its API. I wrote a blog post about C++11 in Qt 4.8 before the 4.8 release which I won't repeat here.

Historically, LXQt is the product of the merge between LXDE-Qt, an initial Qt flavour of LXDE, and Razor-qt, a project I run assert False in the else clause.

Example project @ code.qt.io I have recently made my first OpenGL program rendering a cube, which I extended to include some other basic features (rotate, zoom, pan, mouse selection of vertices). However, I think the program was Q_ASSERT will now expand the condition even in release mode when asserts are disabled, albeit in an unreachable code path. This solves compiler warnings about variables and functions that were unused in release mode because they were only used in assertions. Hi, I compiled QT5 and QT Creator on windows 7 X64, and I'm having an annoying problem when I create a project in QTCreator, everything works fine in both debug and release builds until I use the QTreeView widget (model based) whenever I try to select the I am still relatively new to Qt and I have recently been working on a large project.

The main usage is to use the qtbot fixture, responsible for handling qApp creation as needed and provides methods to simulate user interaction, like key presses and mouse clicks:. def test_hello (qtbot): widget = HelloWidget qtbot. addWidget (widget) # click in the Greet button and If your program has long running computations running in other threads or processes, you can use qtbot.waitSignal to block a test until a signal is emitted (such as QThread.finished) or a timeout is reached.This makes it easy to write tests that wait until a computation running in another thread or process is completed before ensuring the results are correct: then there is still a parallel question, I need to make the button become active only when I select the row, not the cell. something to hang an event? The Qt model/view APIs are used throughout Qt — in Qt Widgets, in Qt Quick, as well as in other non-GUI code.
