ScrollEvent

public ScrollEvent(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

getDirection

public int getDirection()

Extracts the direction of a scroll event.

Gibt zurück:

the scroll direction of @event

getUnit

public int getUnit()

Extracts the scroll delta unit of a scroll event.

The unit will always be %GDK_SCROLL_UNIT_WHEEL if the scroll direction is not
%GDK_SCROLL_SMOOTH.

Gibt zurück:

the scroll unit.

isStop

public boolean isStop()

Check whether a scroll event is a stop scroll event.

Scroll sequences with smooth scroll information may provide
a stop scroll event once the interaction with the device finishes,
e.g. by lifting a finger. This stop scroll event is the signal
that a widget may trigger kinetic scrolling based on the current
velocity.

Stop scroll events always have a delta of 0/0.

Gibt zurück:

%TRUE if the event is a scroll stop event

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
