Mouse wheel event structure (event.wheel.*)

Available Since: This struct is available since SDL 3.2.0.

Fields

type_: SDL_EventType

< SDL_EVENT_MOUSE_WHEEL

reserved: Uint32

timestamp: Uint64

< In nanoseconds, populated using SDL_GetTicksNS()

windowID: SDL_WindowID

< The window with mouse focus, if any

which: SDL_MouseID

< The mouse instance id in relative mode or 0

x: f32

< The amount scrolled horizontally, positive to the right and negative to the left

y: f32

< The amount scrolled vertically, positive away from the user and negative toward the user

direction: SDL_MouseWheelDirection

< Set to one of the SDL_MOUSEWHEEL_* defines. When FLIPPED the values in X and Y will be opposite. Multiply by -1 to change them back

mouse_x: f32

< X coordinate, relative to window

mouse_y: f32

< Y coordinate, relative to window

integer_x: Sint32

< The amount scrolled horizontally, accumulated to whole scroll “ticks” (added in 3.2.12)

integer_y: Sint32

< The amount scrolled vertically, accumulated to whole scroll “ticks” (added in 3.2.12)
