You get the cursor position by calling GetCursorPos.
POINT p;
if (GetCursorPos(&p))
{
//cursor position now in p.x and p.y
}
This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.
if (ScreenToClient(hwnd, &p))
{
//p.x and p.y are now relative to hwnd's client area
}
You hide and show the cursor with ShowCursor.
ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again
You must ensure that every call to hide the cursor is matched by one that shows it again.
My guess for downvote is, GetCursorPos retrieves screen coordinates while the question asked explicitly for window coordinates.
ScreenToClient/MapWindowPointsis missing from your answer.What happens if the hiding and showing calls are not matched? Does it leave the cursor hidden even after the windows/program is closed?
If you're working with OpenGL like I was when I found this, you might find GetClientRect(HWND, LPRECT) as useful as I found this when you are flipping the mouse y coord. Cheers
