Function documentation

PointerEventSource Magnum::Platform::AndroidApplication::PointerMoveEvent::source() const

Pointer event source.

Can be used to distinguish which source the event is coming from in case it's a movement with both pointer() and pointers() being empty.

Containers::Optional<Pointer> Magnum::Platform::AndroidApplication::PointerMoveEvent::pointer() const

Pointer type that was added or removed from the set of pressed pointers.

Use pointers() to query the set of pointers pressed in this event. This field is is non-empty only in case a mouse button was pressed in addition to an already pressed button, or if one mouse button from multiple pressed buttons was released. If non-empty and pointers() don't contain given Pointer value, the button was released, if they contain given value, the button was pressed.

Pointers Magnum::Platform::AndroidApplication::PointerMoveEvent::pointers() const

Pointer types pressed in this event.

Returns an empty set if no pointers are pressed, which happens for example when a mouse is just moved around.

bool Magnum::Platform::AndroidApplication::PointerMoveEvent::isPrimary() const

Whether the pointer is primary.

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

Long Magnum::Platform::AndroidApplication::PointerMoveEvent::id() const

Pointer ID.

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

Vector2 Magnum::Platform::AndroidApplication::PointerMoveEvent::position() const

Position.

May return fractional values if the touch hardware has sub-pixel precision. Use Math::round() to snap them to the nearest window pixel.

Vector2 Magnum::Platform::AndroidApplication::PointerMoveEvent::relativePosition() const

Position relative to the previous touch event.

May return fractional values if the touch hardware has sub-pixel precision. Use Math::round() to snap them to the nearest window pixel. Unlike Sdl2Application, Android APIs don't provide relative position directly, so this is calculated explicitly as a delta from previous move event position.
