Behaviour for processing object state changes.

Member Enumeration Documentation

◆ MultitouchType_t

enum CGUIMultitouchBehaviour::MultitouchType_t

enum for gesture type

Enumerator
MT_SCALE	scaling
MT_SCROLL	scrolling

Constructor & Destructor Documentation

◆ CGUIMultitouchBehaviour()

CGUIMultitouchBehaviour::CGUIMultitouchBehaviour	(	const MultitouchType_t &	eType,
		const eC_Bool &	bKeepCenter,
		const eC_Value &	vFactor
	)

Constructor

Parameters

eType	type of gesture
bKeepCenter	if true the center of the object will be retained
vFactor	factor for gesture

Member Function Documentation

◆ DoScale()

virtual eC_Bool CGUIMultitouchBehaviour::DoScale ( const eC_Value & vDelta )

protectedvirtual

Slot for handling scaling-events will be called if a gesture has been detected which results in scaling

Parameters

vDelta delta for span (radius of circle around touches)

Returns: True If the event has been handled.
false Else.

Reimplemented from CGUIBehaviour.

◆ DoScroll()

virtual eC_Bool CGUIMultitouchBehaviour::DoScroll	(	const eC_Value &	vAbsX,
		const eC_Value &	vAbsY,
		const eC_Value &	vDelta,
		const eC_Bool &	bModifierActive
	)

protectedvirtual

Called when the mouse wheel was scrolled

Parameters

vAbsX	X-position of the mouse in screen coordinates
vAbsY	Y-position of the mouse in screen coordinates
vDelta	number of pixels for scroll
bModifierActive	if true the scroll modifier is active (e.g. left/right instead of up/down)

Returns: True If the event has been handled.
false Else.

Reimplemented from CGUIBehaviour.

◆ GetFactor()

eC_Value CGUIMultitouchBehaviour::GetFactor ( ) const

Get the factor used for scaling and scrolling

Returns: factor

◆ GetKeepCenter()

eC_Bool CGUIMultitouchBehaviour::GetKeepCenter ( ) const

Get if the object should keep its center

Returns: true if center will be kept

◆ GetType()

MultitouchType_t CGUIMultitouchBehaviour::GetType ( ) const

Get the current set type of processing

Returns: the type

◆ ReadFromStream()

virtual void CGUIMultitouchBehaviour::ReadFromStream ( )

virtual

Reads all attributes from streaming file. This method is called by CGUIFactoryManager after one of the registered factories has created an instance of this class.

Reimplemented from CGUIStreamableObject.

◆ SetFactor()

void CGUIMultitouchBehaviour::SetFactor ( const eC_Value & vFactor )

Set the factor for scaling and scrolling

Parameters

vFactor the factor used for scaling and scrolling for scaling this factor will be multiplied with the delta movement for scrolling this factor is the number of pixels the object is moved

◆ SetKeepCenter()

void CGUIMultitouchBehaviour::SetKeepCenter ( const eC_Bool & bKeepCenter )

Set the keep center position when resizing the object

Parameters

bKeepCenter if true the object will keep its center position

◆ SetType()

void CGUIMultitouchBehaviour::SetType ( const MultitouchType_t & eType )

Set the type of processing, either scaling or scrolling

Parameters

eType scaling or scrolling

◆ WriteToStream()

virtual void CGUIMultitouchBehaviour::WriteToStream ( const eC_Bool bWriteClassID = false )

virtual

Writes all attributes to the streaming file. A CGUIStreamWriter has to be initialized first.

Parameters

bWriteClassID This flag is used to select if writing of command class ID, leading and trailing tags is performed.

Reimplemented from CGUIStreamableObject.
