Generate mouse events using Qt framework

Question

I am using Qt framework and I would like to generate mouse events outside my application window.

So far I managed to move the mouse pointer using:

QGuiApplication::overrideCursor()->setPos(x,y);

How can I also generate left mouse button click, middle button click, right button click and mouse wheel movement?

Answer 1

A few years ago i wrote a drivers for GUI testing (for mouse and keyboard). Drivers are developed for Windows, Linux and MacOS X. You can look at here. There is a OS depended MouseDriver implementation for Windows. Also you can see other implementations. This is a open source project, you can use it code for free.

Answer 2

There's no way to do that with Qt. Use APIs specific for your target platform.

Answer 3

Addition to first answer. For example in Windows:

Click:

mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP,x,y,0,0);

Wheel:

mouse_event(MOUSEEVENTF_WHEEL, 0, 0, WHEEL_DELTA, NULL);

Use also qt macros:

#ifdef Q_WS_X11
//Linux
#endif
#ifdef Q_WS_WIN
//Windows
#endif
#ifdef Q_WS_MACX
//Mac
#endif
