C++ (Cpp) setCurrentCursor Examples

Example #1

// XXX: this is a mess!
void QMultiScreenCursor::move(int x, int y)
{
    const int oldIndex = qt_screen->subScreenIndexAt(pos);
    QScreenCursor::move(x, y); // updates pos
    const int newIndex = qt_screen->subScreenIndexAt(pos);

    if (!currentCursor && oldIndex != -1)
        setCurrentCursor(cursors.at(oldIndex));
    QScreenCursor *oldCursor = currentCursor;

    if (oldIndex != -1) {
        const QScreen *oldScreen = qt_screen->subScreens().at(oldIndex);
        if (newIndex == -1 || oldScreen->region().contains(pos)) {
            oldCursor->move(x, y);
            return;
        }
    }

    if (newIndex != -1) {
        QScreenCursor *newCursor = cursors.at(newIndex);
        newCursor->set(cursor, hotspot.x(), hotspot.y());

        if (oldCursor) {
            if (oldCursor->isVisible())
                newCursor->show();
            oldCursor->hide();
        }

        newCursor->move(x, y);

        setCurrentCursor(newCursor);
    }
}
