      Description

      Sending mouse events outside of a window is something that happens in real world scenarios: dragging a selection past the edge of the window to scroll a canvas, for example. As sending these events does actually work, there should be a way to ignore the unwanted warnings that testlib produces.

      hasMatch() returns true, but the test still fails:

      #include <QtTest>
      
      // add necessary includes here
      
      class Test : public QObject
      {
          Q_OBJECT
      
      public:
          Test();
          ~Test();
      
      private slots:
          void test_case1();
      
      };
      
      Test::Test()
      {
      
      }
      
      Test::~Test()
      {
      
      }
      
      void Test::test_case1()
      {
          QWindow window;
          window.resize(400, 400);
      
          // Start inside and drag outside (e.g. moving a selection to the edge of a
          // canvas should scroll the canvas).
          QTest::mousePress(&window, Qt::LeftButton, Qt::NoModifier, QPoint(200, 200));
      
          const QRegularExpression regex(".*Mouse event at .* occurs outside of target window.*");
          QVERIFY(regex.isValid());
      
          const QRegularExpressionMatch match(regex.match("Mouse event at 600, 600 occurs outside of target window (400x400)."));
          QVERIFY(match.hasMatch());
      
          QTest::ignoreMessage(QtWarningMsg, regex);
          QTest::mouseMove(&window, QPoint(600, 600));
      
          QTest::ignoreMessage(QtWarningMsg, regex);
          QTest::mouseRelease(&window, Qt::LeftButton, Qt::NoModifier, QPoint(600, 600));
      }
