The Q_INT64_C () and Q_UINT64_C () macros wrap signed and unsigned 64-bit integer literals in a platform-independent way. whenever I try to select the last item in the list I get the error "ASSERT failure in QList::at: "index out of range", file c:\qt\x64\5.0.0\msvc2010\qtbase\include\qtcore../../src/corelib/tools/qlist.h, line 454, and this is not my apps only, every app I tried did this, even with the X86 QT version I downloaded from here, is this is a known bug ? , I new to qt btw. 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. 在使用Qt开发大型软件时,难免要调试程序,以确保程序内的运算结果符合我们的预期。在不符合预期结果时,就直接将程序断下,以便我们修改。这就用到了Qt中的调试断言 - Q_ASSERT用一个小例子来说一下 Q_ASSERT 断言的作用吧:用QtCreator新建一个控制台程序:代码编写如下:#include int … The Q_ASSERT macro causes a program to abort whenever the asserted condition is false, but only if the software was built in debug mode.

We have four kinds of specializationd: normal function pointer, pointer to member function, pointer to const member function and functors. Qt中的断言函数有两个: (1) void Q_ASSERT ( bool test ) 当test为假时打印出警告信息。 示例: // File: div.cpp #include int divide(int a, int b) { Q_ASSERT(b != 0); return a / b; } (2) void Q_ASS ### Qt 5: 1114 ### This needs to be removed for next releases of Qt. It is a workaround for vc++ because: 1115 ### Qt exports QPolygon and QPolygonF that inherit QVector and: 1116 ### QVector respectively.

This solves compiler warnings about variables and functions that were unused in release mode because they were only used in assertions.

Qt assert

As before, the QTEST_MAIN() macro expands to a simple main() method that runs all the test functions, and since both the declaration and the implementation of our test class are in a .cpp file, we also need to include the generated moc file to make Qt's introspection work. 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. When I attempt to run the project I get this error: ASSERT failure in QList::at: "index out of range", file c:\qt\qt5.3.0\5.3\msvc2013_64\include\qtcore\qlist.h, line 479 If the Q_ASSERT are in Qt, you need to fix the problems ASAP anyway, because you cannot rely on the outcome. Q_ASSERT is used when there is an unrecoverable situation.

The Q_FOREACH () and foreach () macros implement Qt's foreach loop. The Q_INT64_C () and Q_UINT64_C () macros wrap signed and unsigned 64-bit integer literals in a platform-independent way.

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. As I tell my students when I deliver Qt trainings: mastering the usage of model/view classes and functions is mandatory knowledge, any non-trivial Qt application is going to be data-driven, with the data coming from a model class.

The Q_ASSERT () and Q_ASSERT_X () enables warning messages of various level of refinement. The Q_FOREACH () and foreach () macros implement Qt's foreach loop. The Q_INT64_C () and Q_UINT64_C () macros wrap signed and unsigned 64-bit integer literals in a platform-independent way.
