Getting+setting cursor pos relative to window client area

SDL Development
1

I know this:

Code:

SDL_GetRelativeMouseState(&mouse.x, &mouse.y);

But how do I change that to be relative to the top,left corner of the window’s client area?

And how do I set the cursor position then?

2

Oh,

SDL_WarpMouseInWindow(SDL_Window* window,
int x,
int y)

But how do I set the cursor pos?

3

I see now that SDL_WarpMouseInWindow SETS the cursor pos within the window. Now the only thing I need to know is how to get the top,left corner of a window’s client area.

(0, 0)

I mean relative to the desktop/entire screen.

SDL_GetRelativeMouseState(&mouse.x, &mouse.y); gets mouse position relative to (0,0) of the entire screen, right?

Now how do I turn that into relative to the (0,0) of the window’s client area?

No, relative to the window.
Relative to the screen - what would be absolute then?Am 05.06.2014 22:59, schrieb polyfrag:

Oh, okay. But how does it know which window, since there might be more than one?

The mouse focus is only associated with one window at a time. SDL_GetMouseFocus will tell you which one (if any.)On Jun 5, 2014, at 8:14 PM, polyfrag wrote:
