int SDL_CaptureMouse | ( | SDL_bool | enabled | ) |
Capture the mouse, to track input outside an SDL window.
enabled | Whether or not to enable capturing |
Capturing enables your app to obtain mouse events globally, instead of just within your window. Not all video targets support this function. When capturing is enabled, the current window will get all mouse events, but unlike relative mode, no change is made to the cursor and it is not restrained to your window.
This function may also deny mouse input to other windows–both those in your application and others on the system–so you should use this function sparingly, and in small bursts. For example, you might want to track the mouse while the user is dragging something, until the user releases a mouse button. It is not recommended that you capture the mouse for long periods of time, such as the entire time your app is running.
While captured, mouse events still report coordinates relative to the current (foreground) window, but those coordinates may be outside the bounds of the window (including negative values). Capturing is only allowed for the foreground window. If the window loses focus while capturing, the capture will be disabled automatically.
While capturing is enabled, the current window will have the SDL_WINDOW_MOUSE_CAPTURE flag set.

Create a cursor, using the specified bitmap data and mask (in MSB format).
The cursor width must be a multiple of 8 bits.
The cursor is created in black and white according to the following:
data | mask | resulting pixel on screen |
0 | 1 | White |

1 | 0 | Inverted color if possible, black if not. |

Uint32 SDL_GetGlobalMouseState | ( | int * | x, |
int * | y | ||
) |
Get the current state of the mouse, in relation to the desktop.
This works just like SDL_GetMouseState(), but the coordinates will be reported relative to the top-left of the desktop. This can be useful if you need to track the mouse outside of a specific window and SDL_CaptureMouse() doesn't fit your needs. For example, it could be useful if you need to track the mouse while dragging a window, where coordinates relative to a window might not be in sync at all times.
x | Returns the current X coord, relative to the desktop. Can be NULL. |
y | Returns the current Y coord, relative to the desktop. Can be NULL. |

Retrieve the current state of the mouse.
The current button state is returned as a button bitmask, which can be tested using the SDL_BUTTON(X) macros, and x and y are set to the mouse cursor position relative to the focus window for the currently selected mouse. You can pass NULL for either x or y.
