win32: simulate a click without simulating mouse movement?

Question

I\'m trying to simulate a mouse click on a window. I currently have success doing this as follows (I\'m using Python, but it should apply to general win32):

Answer 1

This doesn't answer the question, but it does solve my problem:

win32api.ClipCursor((x-1,y-1,x+1,y+1))
win32api.SetCursorPos((x,y))
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTDOWN| \
                     win32con.MOUSEEVENTF_ABSOLUTE,0,0)
win32api.mouse_event(win32con.MOUSEEVENTF_LEFTUP| \
                     win32con.MOUSEEVENTF_ABSOLUTE,0,0)
win32api.ClipCursor((0,0,0,0))

The result is that any movements I'm making won't interfere with the click. The downside is that my actual movement will be messed up, so I'm still open to suggestions.

Answer 2

Try WindowFromPoint() function:

POINT pt;
    pt.x = 30; // This is your click coordinates
    pt.y = 30;

HWND hWnd = WindowFromPoint(pt);
LPARAM lParam = MAKELPARAM(pt.x, pt.y);
PostMessage(hWnd, WM_RBUTTONDOWN, MK_RBUTTON, lParam);
PostMessage(hWnd, WM_RBUTTONUP, MK_RBUTTON, lParam);
