hasState()

bool gnash::SWF::ButtonRecord::hasState

(

Button::MouseState

st

)

const

Check if this ButtonRecord has a DisplayObject for a particular state.

Parameters

state

The Button::MouseState to test for.

Returns

Whether the ButtonRecord should be used for that Button::MouseState.

instantiate()

DisplayObject * gnash::SWF::ButtonRecord::instantiate	(	Button *	button,
		bool	name = true
	)		const

Create a DisplayObject from a ButtonRecord.

Parameters

name	Whether the created DisplayObject requires its own instance name.
button	The button to which the DisplayObject will belong.

Returns

A new DisplayObject. This should never be 0.

read()

bool gnash::SWF::ButtonRecord::read	(	SWFStream &	in,
		TagType	t,
		movie_definition &	m,
		unsigned long	endPos
	)

Read a ButtonRecord from the SWF stream.

Return true if we read a record; false if this is a null

Parameters

endPos

Last stream offset available for a valid read

readRGBTransform()

void gnash::SWF::ButtonRecord::readRGBTransform ( SWFStream &  in )

inline

Read an RGB SWFCxForm for this record.

Cxform is stored in a different tag for SWF2 Buttons (DEFINEBUTTON tag)

References gnash::key::m, read(), gnash::readCxFormRGB(), and gnash::key::t.

valid()

bool gnash::SWF::ButtonRecord::valid ( ) const

inline

Return true if the ButtonRecord is valid.

A ButtonRecord is invalid if it refers to a DisplayObject which has not been defined.
