map Point to instance of Class TimeMap.

flags The flags indicate the keys to operate on. One or more of the following values:

TRACK_DOSEL
Selected keys only.

TRACK_DOALL
All the keys, ignore their selection state.

TRACK_SLIDEUNSEL
Slide unselected keys to the right. Keys are slid by the amount the last key was transformed.

TRACK_RIGHTTOLEFT
Enumerate right to left. If TRACK_SLIDEUNSEL is set, keys will slide to the left.

TRACK_DOSUBANIMS
Sub-Animatables keys as well.

TRACK_DOCHILDNODES
Child Nodes keys as well

TRACK_MAPRANGE
The range, if not locked to first and last key, should be mapped as well.

CoreExport int HitTestTrack	(	TrackHitTab &	hits,
		Rect &	rcHit,
		Rect &	rcTrack,
		float	zoom,
		int	scroll,
		DWORD	flags
	)

virtual

Remarks: This method is called to determine which keys lie within the rcHit rectangle. Keys that are hit are added to the hits table.

Parameters

hits	The table of TrackHitRecords to update. Each key that lies within the hit rectangle (is hit) should be added to this table. It is up to the plug-in to define a scheme that allows it to identify its hits using the data members of Class TrackHitRecord. Also see Class Tab for methods to add to the table.
rcHit	This is the region that was selected for hit testing. This may be a small rectangle about the mouse pick point, or a larger rectangle if the user selected by window.
rcTrack	This is the entire rectangular region of the track.
zoom	The is the time zoom factor.
scroll	This is the time scroll factor.
flags	One or more of the following value: HITTRACK_SELONLY Selected only. HITTRACK_UNSELONLY Unselected only. HITTRACK_ABORTONHIT Abort hit testing on first hit. HITCURVE_TESTTANGENTS Hit test curve tangents.

Returns: One of the following values:

TRACK_DONE
This indicates the track was hit tested.

TRACK_DORANGE
This indicates that the system will handle hit testing to the range bar for the item. For example a node returns this value because it does not have any keys. Therefore it just lets the user hit test the range bar. In general, anything that is not a leaf controller will not implement this method and return the default. The system will then simply hit test the range bar.

TRACK_ASKCLIENT
If a plug-in returns this value then the anim's client will be given a chance to paint the track in Track View. If a client returns this value then the method PaintSubTrack() will be called.

Default Implementation:: { return TRACK_DORANGE; }

Reimplemented from Animatable.

CoreExport int PaintTrack	(	ParamDimensionBase *	dim,
		HDC	hdc,
		Rect &	rcTrack,
		Rect &	rcPaint,
		float	zoom,
		int	scroll,
		DWORD	flags
	)

virtual

Remarks: This method is called to display the item in the track view. If an item needs to draw itself in a special fashion, it implements this method to do so. For example, a sound plug-in may draw its waveform using this method. If an item does not need to draw itself, the default implementation may be used. This draws the range bar for the item.

Note: When drawing something to appear in Track View, a developer should not do any clipping of their own. 3ds Max will take care of all clipping itself.

Parameters

dim	The dimension for the parameter of this track.
hdc	The handle of the device context.
rcTrack	The entire rectangle of the inside of the track.
rcPaint	This is the rectangular region that needs to be repainted - the invalid region.
zoom	The time zoom factor.
scroll	The time scroll factor.
flags	One or more of the following values which are filters for controllers with more than one curve: DISPLAY_XCURVE DISPLAY_YCURVE

Note: RGB controllers interpret X as red, Y as green, and Z as blue. DISPLAY_ZCURVE

Returns: One of the following values:

TRACK_DONE
Indicates the track was painted.

TRACK_DORANGE
Indicates the system should draw the range bars for the item.

TRACK_ASKCLIENT
Indicates the anim's client will be given a chance to paint the track in Track View. See Animatable::PaintSubTrack() which will be called to do this.

Default Implementation:: { return TRACK_DORANGE; }

Reimplemented from Animatable.

CoreExport void SelectKeys	(	TrackHitTab &	sel,
		DWORD	flags
	)

virtual

Remarks: This method is called to select or deselect a set of keys identified by the TrackHitTab and the specified flags.

Parameters

sel The table of track hit records. See Class TrackHitRecord and Class Tab. Note the following: typedef Tab<TrackHitRecord> TrackHitTab;

flags Either SELKEYS_SELECT, SELKEYS_DESELECT, or a combination of SELKEYS_CLEARKEYS and SELKEYS_CLEARCURVE will be specified.

One or more of the following values:

SELKEYS_SELECT
The keys should be selected.

SELKEYS_DESELECT
The keys should be deselected.

SELKEYS_CLEARKEYS
All keys should be deselected.

SELKEYS_CLEARCURVE
All keys on the function curve should be deselected.

SELKEYS_FCURVE
Indicates that we are operating on the keys of a function curve, and not of a track.

Default Implementation:: {}

Reimplemented from Animatable.

CoreExport void SelectKeyByIndex	(	int	i,
		BOOL	sel
	)

virtual

Remarks: This method is available in release 2.0 and later only.

This method is called to set the selected state of the key whose index is passed.

Parameters

i	The key to select or deselect.
sel	TRUE to select the key; FALSE to deselect it.

Default Implementation:: {}

Reimplemented from Animatable.

CoreExport int NumSelKeys ( )

virtual

Remarks: Returns the number of selected keys.

Default Implementation:: {return 0;}

Reimplemented from Animatable.

CoreExport void FlagKey ( TrackHitRecord hit )

virtual

Remarks: This method is called to have the plug-in flag or mark a specific key identified by the TrackHitRecord.

As an example, when the user goes to move a selection set of keys in the Track View, a yellow marker is drawn. To move the group of keys, the user clicks on a single one. The system needs to track this one key as it is moved, and needs a way to identify it. This method is called so the developer can flag this key as the one that was selected. This is needed because the Track View doesn't know anything about a specific controllers ordering of keys and thus cannot refer to it by index.

The system will call GetFlagKeyIndex() (described below) to retrieve the index of the key that was flagged.

Parameters

hit	The hit record that the controller gave the Track View in the first place to identify the hit. Thus this is enough information to identify the key. See Class TrackHitRecord.

Default Implementation:: {}

Sample Code:: template <class KT>

void GenMorphCont<KT>::FlagKey(TrackHitRecord hit)

{

int n = keys.Count();

for ( int i = 0; i < n; i++ ) {

keys[i].ClearFlag(KEY_FLAGGED);

}

assert(hit.hit>=0&&hit.hit<(DWORD)n);

keys[hit.hit].SetFlag(KEY_FLAGGED);

}

Reimplemented from Animatable.

CoreExport int GetFlagKeyIndex ( )

virtual

Remarks: Returns the index of the key that is flagged, or -1 if no keys are flagged. See the method above.

Default Implementation:: {return -1;}

Sample Code:: template <class KT>

int GenMorphCont<KT>::GetFlagKeyIndex()

{

int n = keys.Count();

for ( int i = 0; i < n; i++ ) {

if (keys[i].TestFlag(KEY_FLAGGED)) {

return i;

}

}

return -1;

}

Reimplemented from Animatable.

CoreExport BOOL IsAnimated ( )

inlinevirtual

Remarks: Returns TRUE if this animatable actually has animation; otherwise FALSE. This method is recursive, so for example, if you call node->IsAnimated() it will return TRUE if any aspect of the node is animated; otherwise it will return FALSE.

Default Implementation:: The default implementation returns TRUE if a child anim has animation.

Reimplemented from Animatable.

185 {return TRUE;}

CoreExport void EditTrackParams	(	TimeValue	t,
		ParamDimensionBase *	dim,
		const MCHAR *	pname,
		HWND	hParent,
		IObjParam *	ip,
		DWORD	flags
	)

virtual

Remarks: This method is called for the plug-in to put up a modal dialog and let the user edit the tracks parameters for the selected keys. This function should not return until the user has completed editing at which time any windows that were created should be destroyed. Unlike BeginEditParams() and EndEditParams() this interface is modal.

Parameters

t	This time represents the horizontal position of where the user right clicked to bring up the modal edit track parameters dialog. See the flags below for when this parameter is valid.
dim	The parameter dimension. See Class ParamDimensionBase.
pname	The name of the parameter as given by the client.
hParent	This is the parent window that should be used to create any dialogs.
ip	An interface pointer available for calling functions in 3ds Max.
flags	One or more of the following values: EDITTRACK_FCURVE The user is in the function curve editor. EDITTRACK_TRACK The user is in one of the track views. EDITTRACK_SCENE The user is editing a path in the scene. EDITTRACK_BUTTON The user invoked by choosing the properties button. In this case the time parameter is NOT valid. EDITTRACK_MOUSE The user invoked by right clicking with the mouse. In this case the time parameter is valid.

Default Implementation:: {}

Reimplemented from Animatable.

CoreExport int TrackParamsType ( )

inlinevirtual

Remarks: This method returns a value that indicates how the track parameter editing is invoked.

Returns: One of the following values:

TRACKPARAMS_NONE

Has no track parameters. If this is returned then EditTrackParams() will not be called.

TRACKPARAMS_KEY

Entered by right clicking on a selected key. This should be used if the dialog provides parameters for the entire controller (for example as the Noise controller's dialog does).

TRACKPARAMS_WHOLE

Entered by right clicking anywhere in the track. This should be used if the dialog will represent the selection of keys (as a key info type dialog does).

Default Implementation:: {return TRACKPARAMS_NONE;}

Reimplemented from Animatable.

187 {return TRACKPARAMS_KEY;}

Definition: TrackFlags.h:165

CoreExport BOOL SupportTimeOperations ( )

inlinevirtual

Remarks: If an anim supports time operations in the track view (cut, copy, paste, etc.), it should implement this method to return TRUE. When it is FALSE the user cannot select blocks of time in the anim's track.

Default Implementation:: {return FALSE;}

Reimplemented from Animatable.

188 {return TRUE;}

CoreExport IOResult Save ( ISave * isave )

virtual

Called for saving data.

Called by the system to allow the plugin to save its data.

Parameters

isave - This pointer may be used to call methods to write data to disk. See the section on Loading and Saving Plug-in Data for an overview of the load/save process.

Returns

The default implementation is return IO_OK.

IO_OK means the result was acceptable, with no errors.
IO_ERROR This should be returned if an error occurred.

Reimplemented from ReferenceMaker.

CoreExport IOResult Load ( ILoad * iload )

virtual

Called for loading data.

Called by the system to allow the plug-in to load its data. See the section on Loading and Saving Plug-in Data for an overview of the load - save process.

Parameters

iload - This interface pointer may be used to call methods to read data from disk.

Returns

The default implementation is return IO_OK.

IO_OK means the result was acceptable, with no errors.
IO_ERROR This should be returned if an error occurred.

Reimplemented from ReferenceMaker.

CoreExport void DeleteThis ( )

virtual

Deletes an instance of this class.

3ds Max calls this method when it needs to delete a plugin object (an instance of a class derived from Animatable). Similarly, plugins that need to delete instances of an Animatable or a class directly derived from it via an Animatable pointer, should call this method instead of calling directly operator delete. Following these rules will ensure that the same memory manager is used to allocate and deallocate the object. The default implementation of this method deletes the object. Plugin instances that never need to be deleted from the heap can overwrite this method to do nothing.

Note: See the method ClassDesc::Create() for details on how Max allocates plugin objects.; See ReferenceMaker::DeleteMe() and ReferenceTarget::MaybeAutoDelete() for information on how plugin instances are deleted by the system.

Remarks: See Memory Management.

Receives and responds to messages.

A plugin which makes references must implement a method to receive and respond to messages broadcast by its dependents. This is done by implementing NotifyRefChanged(). The plugin developer usually implements this method as a switch statement where each case is one of the messages the plugin needs to respond to. The Method StdNotifyRefChanged calls this, which can change the partID to new value. If it doesn't depend on the particular message& partID, it should return REF_DONTCARE.

For developer that need to update a dialog box with data about an object you reference note the following related to this method: This method may be called many times. For instance, say you have a dialog box that displays data about an object you reference. This method will get called many time during the drag operations on that object. If you updated the display every time you'd wind up with a lot of 'flicker' in the dialog box. Rather than updating the dialog box each time, you should just invalidate the window in response to the NotifyRefChanged() call. Then, as the user drags the mouse your window will still receive paint messages. If the scene is complex the user may have to pause (but not let up on the mouse) to allow the paint message to go through since they have a low priority. This is the way many windows in 3ds Max work.

Parameters

changeInt	- This is the interval of time over which the message is active. Currently, all plug-ins will receive FOREVER for this interval, with the exception of REFMSG_FLAGDEPENDENTS notifications. In that case, changeInt.Start() is the timepoint to perform the dependency test.
hTarget	- This is the handle of the reference target the message was sent by. The reference maker uses this handle to know specifically which reference target sent the message.
partID	- This contains information specific to the message passed in. Some messages don't use the partID at all. See the section List of Reference Messages for more information about the meaning of the partID for some common messages.
message	- The message parameters passed into this method is the specific message which needs to be handled.
propagate	- If called through ReferenceMaker::NotifyDependents(), the value of 'propagate' passed to it. Used if calling NotifyDependents() from within NotifyRefChanged().

Returns: The return value from this method is of type RefResult. This is usually REF_SUCCEED indicating the message was processed. Sometimes, the return value may be REF_STOP. This return value is used to stop the message from being propagated to the dependents of the item.

Implements ReferenceMaker.

195 {return REF_SUCCEED;}

REF_SUCCEED

The operation succeeded.

CoreExport RefTargetHandle Clone ( RemapDir & remap )

virtual

This method is used by 3ds Max to clone an object.

See also: CloneRefHierarchy(), class RemapDir This method is called by 3ds Max to have the plugin clone itself. The plug-in's implementation of this method should copy both the data structure and all the data residing in the data structure of this reference target. The plugin should clone all its references as well. Also, the plug-in's implementation of this method must call BaseClone(). In order for classes derived from this class to clone cleanly, the Clone method should just create the new instance, and then call an implementation of BaseClone that clones the references and copies any other necessary data. For example:
class MyDerivedPlugin

: public MyBasePlugin

{

const int MY_REFERENCE = 1;

ReferenceTarget* Clone(RemapDir& remap)

{

ReferenceTarget* result = new MyDerivedPlugin();

BaseClone(this, result, remap);

return result;

}

void BaseClone(ReferenceTarget* from, ReferenceTarget* to, RemapDir& remap)

{

if (!to || !from || from == to)

return;

MyBasePlugin::BaseClone(from, to, remap);

to->ReplaceReference(MY_REFERENCE, remap->CloneRef(from->GetReference(MY_REFERENCE)));

}

};

This method should not be directly called by plug-ins. Instead, either RemapDir::CloneRef() or CloneRefHierachy() should be used to perform cloning. These methods ensure that the mapping from the original object to the clone is added to the RemapDir used for cloning, which may be used during backpatch operations

Note: See the remarks in method BaseClone() below.

Parameters

remap - A RemapDir instance used for remapping references during a Clone.

Returns: A pointer to the cloned item.

Reimplemented from ReferenceTarget.
