Windows C ++模拟单击管理

Question

I have a program in Qt5 Windows 10 where I simulate clicks (to help a friend with a disability with a special device). I use SendInput. The problem is that when I simulate a click to press a key on the Windows Virutal Keyboard (osk.exe), it does not work. In fact, it works but only if I run the program as administrator. However, I would like it to work even when the program is not run as admin.

Any suggestions ?

Qt has everything you need in order to simulate input, so you don't need to use SendInput

First, create a QMouseEvent and then call QCoreApplication::postEvent

The implementation would depend on what exactly you want to simulate, but your code would look something like this:

// Pos is the position of the click
QMouseEvent *me = new QMouseEvent(QEvent::MouseButtonPress, pos, Qt::LeftButton, Qt::LeftButton, Qt::NoModifier);

QCoreApplication::postEvent(reciever, me); // Where reciever is a QObject handling the event

EDIT : Another snippet worth trying:

#include <windows.h>

QApplication::desktop()->cursor().setPos(globalX,globalY);
mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 1, 1, 0, 0);
