I'm looking for draw HCURSOR in my window. The cursor has to be the real cursor from another window (HWND).
Here is my code:
GetCursorPos(&pos);
ScreenToClient(hwnd, &pos);
DrawIcon(hdcMemDC, pos.x, pos.y,GetCursor());
It draw a cursor on my window, but it's not the "real" Windows cursor. Example, when on another window i got a hand mouse icon, mine doesn't change.
So i would like to know if it's possible to handle the "real" cursor from a specified window (HWND) and draw it. Something like GetCursorOf(hwnd, &myCursorInfo)
would be cool.
This code will get the cursor of any window. It will then create a thread and that thread will constantly draw the cursor onto our window.
