C++ (Cpp) QWindow::isVisible Examples

Example #1

File: qplatformscreen.cpp Project: venkatarajasekhar/Qt

/*!
    Return the given top level window for a given position.

    Default implementation retrieves a list of all top level windows and finds the first window
    which contains point \a pos
*/
QWindow *QPlatformScreen::topLevelAt(const QPoint & pos) const
{
    QWindowList list = QGuiApplication::topLevelWindows();
    for (int i = list.size()-1; i >= 0; --i) {
        QWindow *w = list[i];
        if (w->isVisible() && w->geometry().contains(pos))
            return w;
    }

    return 0;
}
