Description
With the code
class Widget : public QWidget { protected: bool event(QEvent *e) override { if (e->type() == QEvent::WinIdChange) { if (const auto win_handle = windowHandle()) QWindowsWindowFunctions::setHasBorderInFullScreen(win_handle, true); } return QWidget::event(e); } }; WWidget widget; widget->setWindowState(Qt::WindowFullScreen); widget->showMinimized();
the window will not become full screen when unminimized on Windows, or rather that will not be the state the QWidget::windowState() returns after being unminimized. If QWindowsWindowFunctions::setHasBorderInFullScreen() is not used, it works as expected.
A more elaborate example that demonstrates the issue is attached as fullscreen.cc.
