= Window Corner Radius Example =

Demonstrates setting rounded corners on a Qt window.



The main window contains a spin box for the radius and a button that creates a new sub window. The radius is applied with QtOhosExtras::setWindowCornerRadius() immediately before the new window is shown.

<syntaxhighlight lang="cpp">

             auto *newWindow = new QWidget(window);
             newWindow->setWindowFlags(Qt::Window);
             newWindow->setWindowTitle(QLatin1String("OHOS corner radius window"));
             newWindow->resize(QSize{300, 300});
             QtOhosExtras::setWindowCornerRadius(newWindow, spinbox->value());

             newWindow->show();

</syntaxhighlight>

'''Note: '''The radius has to be applied before the window is shown, and the target must be a sub or floating window (for example created with the [https://doc.qt.io/qt-5/qt.html#WindowType-enum Qt::Window] flag or marked with QtOhosExtras::setShowWindowAsFloatWindowHint()). Negative values are rejected.
