Member Function Documentation

◆ Animate()

virtual Bool Animate	(	const CTrack *	track,
		const CAnimInfo *	info,
		Bool *	chg,
		void *	data
	)		const

virtual

Called during redraw or whenever Cinema 4D wants to evaluate the animation track.

Note: All times are given with respect to time curves for instance, so time might not be the same as doc->GetTime().; This function is called in a thread context. See the important information about threading.

Parameters

[in]	track	Equal to `static_cast<CTrack*>->Get()`. Provided for speed and convenience. Cinema 4D owns the pointed track.
[in]	info	The animation parameters. It is the responsibility of each track plugin to interpolate the values in info correctly.
[out]	chg	If not nullptr, set it to true if the value has changed due to the animation.
[out]	data	If not nullptr, the animated value should not be applied to the object, but assigned to this parameter instead.

Returns: true if the track was animated successfully, otherwise false.

◆ GuiMessage()

virtual Int32 GuiMessage	(	CTrack *	track,
		const BaseContainer &	msg,
		BaseContainer &	result
	)

virtual

Called to process GUI messages e.g. for drag-and-drop, drawing etc. Private.

See also: GeDialog::Message for more information.

Parameters

[in]	track	Equal to `static_cast<CTrack*>->Get()`. Provided for speed and convenience. Cinema 4D owns the pointed track.
[in]	msg	The message container.
[in,out]	result	The message result container.

Returns: The GUI message return value.

◆ Draw()

virtual Bool Draw	(	CTrack *	track,
		GeClipMap *	map,
		const BaseTime &	clip_left,
		const BaseTime &	clip_right
	)

virtual

Called to draw additional stuff, e.g. like the sound track draws a sound wave.

Note: Called when GetHeight() returns a positive height for the track of the sequence.; This function is called in a thread context. See the important information about threading.

Parameters

[in]	track	Equal to `static_cast<CTrack*>->Get()`. Provided for speed and convenience. Cinema 4D owns the pointed track.
[out]	map	The clip map to draw to. Cinema 4D owns the pointed clip map.
[in]	clip_left	The left time clipping.
[in]	clip_right	The right time clipping.

Returns: true if the track was drawn successfully, otherwise false.

◆ GetHeight()

virtual Int32 GetHeight ( const CTrack * track ) const

virtual

Called to get the height to draw additional data for the sequence in the timeline, e.g. the sound wave of a sound track.
The default value is 0, which means no additional data.

Parameters

[in] track Equal to static_cast<CTrack*>->Get(). Provided for speed and convenience. Cinema 4D owns the pointed track.

Returns: The extra height of the track in pixels.

◆ FillKey()

virtual Bool FillKey	(	CTrack *	track,
		BaseDocument *	doc,
		BaseList2D *	bl,
		CKey *	key
	)

virtual

Called to fill a newly created key with default values for object bl.

Parameters

[in]	track	Equal to `static_cast<CTrack*>->Get()`. Provided for speed and convenience. Cinema 4D owns the pointed track.
[in]	doc	The document. Cinema 4D owns the pointed document.
[in]	bl	The object of the key. Cinema 4D owns the pointed object.
[out]	key	The key to fill. Cinema 4D owns the pointed key.

Returns: true if the key was filled successfully, otherwise false.

◆ TrackInformation()

virtual Bool TrackInformation	(	CTrack *	track,
		BaseDocument *	doc,
		CKey *	key,
		maxon::String *	str,
		Bool	set
	)

virtual

Called to set (set=true) or get (set==false) information for a track at the current time (key==nullptr) or at a specified key. The information to get/set is available in str. The information is shown in the UI for example when hovering over a value.

Parameters

[in]	track	Equal to `static_cast<CTrack*>->Get()`. Provided for speed and convenience. Cinema 4D owns the pointed track.
[in]	doc	The active document. Cinema 4D owns the pointed document.
[in]	key	The key that the information concerns or nullptr if the information concerns `doc->GetTime()`. Cinema 4D owns the pointed key.
[in,out]	str	The string to get/set.
[in]	set	true if the information should be set, otherwise false if it should be retrieved.

Returns: true if the track information was get/set successfully, otherwise false.

◆ KeyMessage()

		CKey *	node,
		Int32	type,
		void *	data
