How to use QCoreApplication::postEvent to inject synthetic input events

Question

I\'m injecting Keyboard and Mouse events which are comming over the network into my Qt Application and use QCoreApplication::postEvent for this. The mouse coord

Answer 1

I would suggest posting some code as according to the documentation the signature is:

void QCoreApplication::postEvent ( QObject * receiver, QEvent * event ) [static]

Have you tried giving a pointer to the corresponding QObject as the receiver argument?

(edit: note that QWidget inherits QObject)

Answer 2

Here is the Answer that was added to the Question:

I now use the following which works fine (Many thanks to Dusty Campbell):

QPoint pos(x, y);
QWidget *receiver = QApplication::widgetAt(pos);
if (receiver) {
    QMouseEvent *event = new QMouseEvent(type, receiver->mapFromGlobal(pos),
        mouse_button, mouse_buttons, Qt::NoModifier);
    QCoreApplication::postEvent(receiver, event);
}

Answer 3

Can you use QApplication::widgetAt() to find the correct widget at the position and then post to that?

QPoint pos(x, y);
QMouseEvent *event = new QMouseEvent(type, pos, mouse_button, mouse_buttons,  Qt::NoModifier);
QWidget *receiver = QApplication::widgetAt(pos);
QCoreApplication::postEvent(receiver, event);

I wouldn't expect that you would have to do this for the key events though. They should be sent to the focused widget (QApplication::focusWidget()).

Unfortunately, I haven't tested any of this.
