Relative Mouse Mode
setRelativeMouseMode :: (Functor m, MonadIO m) => Bool -> m () Source
Sets the current relative mouse mode.
When relative mouse mode is enabled, cursor is hidden and mouse position will not change. However, you will be delivered relative mouse position change events.
Throws SDLException on failure.
getRelativeMouseMode :: MonadIO m => m Bool Source
Check if relative mouse mode is enabled.
Mouse and Touch Input
data MouseButton Source
Constructors
| ButtonLeft | |
| ButtonMiddle | |
| ButtonRight | |
| ButtonX1 | |
| ButtonX2 | |
| ButtonExtra !Int | An unknown mouse button. |
data MouseDevice Source
Identifies what kind of mouse-like device this is.
Mouse State
getMouseLocation :: MonadIO m => m (Point V2 CInt) Source
Retrieve the current location of the mouse, relative to the currently focused window.
getMouseButtons :: MonadIO m => m (MouseButton -> Bool) Source
Retrieve a mapping of which buttons are currently held down.
Warping the Mouse
data WarpMouseOrigin Source
warpMouse :: MonadIO m => WarpMouseOrigin -> Point V2 CInt -> m () Source
Move the current location of a mouse pointer. The WarpMouseOrigin specifies the origin for the given warp coordinates.
Cursor Visibility
cursorVisible :: StateVar Bool Source
Get or set whether the cursor is currently visible.
This StateVar can be modified using $= and the current value retrieved with get.
See SDL_ShowCursor and SDL_HideCursor for C documentation.
Cursor Shape
activeCursor :: StateVar Cursor Source
Get or set the currently active cursor. You can create new Cursors with createCursor.
This StateVar can be modified using $= and the current value retrieved with get.
See SDL_SetCursor and SDL_GetCursor for C documentation.
Arguments
| :: MonadIO m | |
| => Vector Bool | Whether this part of the cursor is black. Use |
| -> Vector Bool | Whether or not pixels are visible. Use |
| -> V2 CInt | The width and height of the cursor. |
| -> Point V2 CInt | The X- and Y-axis location of the upper left corner of the cursor relative to the actual mouse position |
| -> m Cursor |
Create a cursor using the specified bitmap data and mask (in MSB format).
freeCursor :: MonadIO m => Cursor -> m () Source
Free a cursor created with createCursor and createColorCusor.
See SDL_FreeCursor for C documentation.
Create a color cursor.
See SDL_CreateColorCursor for C documentation.
