Function documentation

bool Magnum::Platform::Sdl2Application::PointerEvent::isPrimary() const

Whether the pointer is primary.

Useful to distinguish among multiple pointers in a multi-touch scenario. See Touch input in SDL2 for more information.

Long Magnum::Platform::Sdl2Application::PointerEvent::id() const

Pointer ID.

Useful to distinguish among multiple pointers in a multi-touch scenario. See Touch input in SDL2 for more information.

Vector2 Magnum::Platform::Sdl2Application::PointerEvent::position() const

Position.

For mouse input the position is always reported in whole pixels. For Pointer::Finger the events may be reported with a subpixel precision, use Math::round() to snap them to the nearest pixel. Note that, unlike the SDL_TouchFingerEvent, which is normalized in the range, the position for touch events is in the same coordinate system as mouse events.

Int Magnum::Platform::Sdl2Application::PointerEvent::clickCount() const

Click count.

For Pointer::Finger is always 1.

Sdl2Application::Modifiers Magnum::Platform::Sdl2Application::PointerEvent::modifiers()

Keyboard modifiers.
