<![CDATA[QPixmap::grabWindow how to grab mouse cursor ?]]>Sometimes need mouse cursor to point out the position of the screen.
But the way below can not grab mouse cursor.

QPixmap pixmap = QPixmap::grabWindow(QApplication::desktop()->winId());

hi
Can you try
QPoint p = QCursor::pos();
that is global mouse pos. not mapped to local coors for a widget.

#include <QApplication>
#include <QStandardPaths>
#include <QWidget>
#include <QScreen>
#include <QClipboard>
#include <QDateTime>
#include <QPainter>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QWidget *widget = new QWidget;
    QScreen *screen = QGuiApplication::primaryScreen();
    QPixmap pixmap = screen->grabWindow(0);
    QPixmap pixmap_mouse(":/mouse.png");
    QPainter painter(&pixmap);
    painter.drawPixmap(widget->cursor().pos(),pixmap_mouse);
    QApplication::clipboard()->setPixmap(pixmap, QClipboard::Clipboard);
    QDateTime time = QDateTime::currentDateTime();
    QString filename = time.toString("yyyyMMddhhmmss") + ".jpg";
    QString path = QStandardPaths::standardLocations(QStandardPaths::DesktopLocation).first() + "/" + filename;
    pixmap.save(path,0,100);
    return 0;
}

QPixmap pixmap = QPixmap::grabWindow(QApplication::desktop()->winId());
QPixmap pixmap_mouse(":/mouse.png");
QPainter painter(&pixmap);
painter.drawPixmap(300,200,pixmap_mouse);

But still can not get system mouse position.

hi
I dont think you can return a pixmap for the system cursors.
Its only if you constructed a custom one using
QCursor::QCursor(const QPixmap &pixmap, int hotX = -1, int hotY = -1)
As far as I know.

QPixmap pixmap = QPixmap::grabWindow(QApplication::desktop()->winId());
QPainter painter(&pixmap);
painter.drawPixmap(500,500,QCursor(Qt::ArrowCursor).pixmap());

That's not the goal of grabWindow, however what you can do is draw the point of interest on the pixmap you get.
