Detailed Description

A proxy for a class descriptor.

Plug-ins do not need to work directly with this class. When a plug-in DLL is defer loaded, the plug-in classes it exposes are represented by instances of this class. When the DataClassDesc instance does not have enough information to query out a request from client code, it will load the plug-in DLL which exposes the actual ClassDesc the DataClassDesc is a proxy for. From that point on, the actual ClassDesc instance is used. When a DataClassDesc instance is replaced by a full class descriptor, inside of ClassDirectory::AddClass then a notification is sent:

BroadcastNotification(NOTIFY_CLASSDESC_REPLACED, &cdr);

NOTIFY_CLASSDESC_REPLACED

#define NOTIFY_CLASSDESC_REPLACED

Provides a notification that a ClassDesc is being replaced by another one.

Definition: notify.h:548

BroadcastNotification

CoreExport void BroadcastNotification(int code)

Overwrites ClassDesc::IsPublic()

Implements ClassDesc.

◆ Create()

virtual CoreExport void* Create ( BOOL loading = FALSE )

virtual

3ds Max calls this method when it needs a pointer to a new instance of the plug-in class.

For example, if 3ds Max is loading a file from disk containing a previously used plug-in (procedural object, modifier, controller, etc...), it will call the plug-in's Animatable::Create() method. The plug-in responds by allocating a new instance of its plug-in class. See the Advanced Topic section on Memory Management for more details.

Parameters

loading This parameter is a flag indicating if the class being created is going to be loaded from a disk file. If the flag is TRUE, the plug-in may not have to perform any initialization of the object because the loading process will take care of it. See the Advanced Topics section on Loading and Saving Plug-in Data for more information.

Note: If this parameter is TRUE, developers must initialize their references to NULL. Otherwise 3ds Max may crash.

3ds Max provides a default plug-in object creation process. Many plug-ins fit this form. When the system is about to create an instance of the plug-in object it calls a method BaseObject::GetCreateMouseCallBack().This method returns a callback object whose proc() method handles the mouse input during its creation phase. Most of the work is then handled by the system. The procedural sphere is an example of this type of plug-in. Certain plug-ins may have special creation needs however. The target camera is an example of such a plug-in. Because it needs to create two nodes in the scene (the camera and the target) it requires a custom creation process. To support these plug-ins the following two methods are provided. They allow the plug-in to manage the creation process themselves. See Object Creation Methods for more details.

Implements ClassDesc.

◆ BeginCreate()

virtual CoreExport int BeginCreate ( Interface * i )

virtual

The custom creation process of the plug-in object is handled by this method.

For example, a plug-in can create a custom command mode and push it on the command stack to handle the creation process.

Important Note: A plug-in that doesn't want to participate in the standard object creation mechanism using CreateMouseCallBack must push a CommandMode on the stack in this method and remove it in EndCreate(). This is true even if the plug-in doesn't do anything inside the mode. A mode has to be pushed on the stack and then later popped off otherwise a crash will occur (if the default implementation of this method is not used). For more details on object creation see the Advanced Topics section Object Creation Methods.

Parameters

i	An interface pointer the plug-in may use to call functions in 3ds Max.

Returns: To use the default creation process (the system implementation for this method) return 0; Return nonzero if the plug-in implements this method.

Reimplemented from ClassDesc.

◆ EndCreate()

virtual CoreExport int EndCreate ( Interface * i )

virtual

The termination of the custom creation process is managed by the implementation of this method.

For example, the plug-in could remove a custom command mode from the command stack. See the Advanced Topics section on Object Creation Methods for more details.

Parameters

i	An interface pointer the plug-in may use to call functions in 3ds Max.

Returns: To use the system implementation for this method return 0; Return nonzero if the plug-in implements this method.

Reimplemented from ClassDesc.

Reimplemented from ClassDesc.

◆ HasClassParams()

virtual CoreExport BOOL HasClassParams ( )

virtual

If a plug-in class has default parameters that it needs to allow the user to edit, TRUE should be returned and EditClassParams() and ResetClassParams() should be implemented.

Otherwise return FALSE (the default).

Reimplemented from ClassDesc.

◆ EditClassParams()

virtual CoreExport void EditClassParams ( HWND hParent )

virtual

If the user picks the class from the list this method is called.

The plug-in should put up a modal dialog that allows the user to edit the plug-ins default parameters. The plug-in should not return until the user has finished editing the parameters.

Parameters

hParent The parent window handle.

Reimplemented from ClassDesc.

◆ ResetClassParams()

virtual CoreExport void ResetClassParams ( BOOL fileReset = FALSE )

virtual

When the user executes File / Reset or presses the 'Reset to Factory Settings...' button in the File / Preferences...

/ Animation tab / Controller Defaults section this method is called. The plug-in can respond by resetting itself to use its default values.

Parameters

fileReset When TRUE, the user has performed a File / Reset operation. When FALSE, the user is in the Preferences... dialog doing a reset controller defaults operation.

Reimplemented from ClassDesc.

◆ NumActionTables()

virtual CoreExport int NumActionTables ( )

virtual

These functions return keyboard action tables that plug-ins can use.

Reimplemented from ClassDesc.

◆ GetActionTable()

virtual CoreExport ActionTable* GetActionTable ( int i )

virtual

Returns a pointer to the specified action table.

Note: Ownership of the ActionTable is transferred to 3ds Max when this function is called, and it should not be deleted by the plug-in.

Parameters

i	The zero based index of the table to return.

See also: ActionTable

Reimplemented from ClassDesc.

◆ IsManipulator()

virtual CoreExport BOOL IsManipulator ( )

virtual

Returns TRUE if the class implements a manipulator object; otherwise FALSE.

Reimplemented from ClassDesc.

◆ CanManipulate()

virtual CoreExport BOOL CanManipulate ( ReferenceTarget * hTarget )

virtual

The method returns true if the class is a manipulator and it manipulates the given base object, modifier or controller.

When starting "Manipulate" mode, this is called on selected nodes for the base object, all modifiers, the TM controller and the position, rotation and scale controllers, if the TM controller is a PRSController.

Parameters

hTarget A pointer to a reference target.

Reimplemented from ClassDesc.

◆ CanManipulateNode()

virtual CoreExport BOOL CanManipulateNode ( INode * pNode )

virtual

Returns TRUE if the manipulator applies to the given node; otherwise FALSE.

This method can be used to indicate that the manipulator works on a part of an object that is not covered by BOOL CanManipulate(ReferenceTarget* hTarget) such as the visibility controller of a node.

Parameters

pNode The INode to check.

Reimplemented from ClassDesc.

◆ CreateManipulator() [1/2]

virtual CoreExport Manipulator* CreateManipulator	(	ReferenceTarget *	hTarget,
		INode *	pNode
	)

virtual

Creates a manipulator object When a manipulator returns TRUE to CanManipulate(ReferenceTarget* hTarget), the system calls this version of CreateManipulator() to create an instance of the manipulator.

Parameters

hTarget	- The ReferenceTarget for which a manipulator is requested
pNode	- The node that the manipulator needs to manipulate (know about)

Returns: - Pointer to the newly created manipulator, or NULL if the creation failed.
Manipulator* BendManipClassDesc::CreateManipulator(ReferenceTarget* hTarget, INode* node) {

if (hTarget->ClassID() != Class_ID(BENDOSM_CLASS_ID, 0))

return NULL;

return (new BendManip((SimpleMod2*)hTarget, node));

◆ CreateManipulator() [2/2]

virtual CoreExport Manipulator* CreateManipulator ( INode * pNode )

virtual

Creates a manipulator object.

When a manipulator returns TRUE to CanManipulateNode(INode* pNode), the system calls this version of CreateManipulator() to create an instance of the manipulator.

Parameters

pNode - The node that the manipulator needs to manipulate (know about)

Returns: - Pointer to the newly created manipulator, or NULL if the creation failed.

Reimplemented from ClassDesc.

◆ NeedsToSave()

virtual CoreExport BOOL NeedsToSave ( )

virtual

Returns TRUE if there is data associated with the class that needs to be saved in the 3ds Max file.

If this is so, implement the Save() and Load() methods below. If there is no class data to save return FALSE.

Reimplemented from ClassDesc.

◆ Save()

virtual CoreExport IOResult Save ( ISave * isave )

virtual

If NeedsToSave() returns TRUE then this method should be implemented to save the data associated with the class.

Parameters

isave A pointer that may be used to call methods to save data to disk.

Returns: IO_OK if the save was successful; otherwise IO_ERROR.

Reimplemented from ClassDesc.

◆ Load()

virtual CoreExport IOResult Load ( ILoad * iload )

virtual

If NeedsToSave() returns TRUE then this method should be implemented to load the data associated with the class.

Parameters

iload A pointer that may be used to load data from a file.

Returns: IO_OK if the load was successful; otherwise IO_ERROR.

Reimplemented from ClassDesc.

◆ InitialRollupPageState()

virtual CoreExport DWORD InitialRollupPageState ( )

virtual

This method returns a DWORD which is used to initialize the rollup state in both the create branch and the modify branch.

The semantics are different, however for these two cases. Whenever the rollups are created in the create branch, their state will be that specified by this method. In the modify branch, the first time an object of this type is modified the state will be that of this method, but after that it will remain what it was last set to.

Returns: The bits of this DWORD set indicate the corrresponding rollup page is closed. The zero bit corresponds to the plug-ins first rollup, the first bit is the second rollup, etc. The value 0x7fffffff is returned by the default implementation so the command panel can detect this method is not being overridden, and just leave the rollups as is.

Reimplemented from ClassDesc.

◆ InternalName()

virtual CoreExport const MCHAR* InternalName ( )

virtual

Returns a string which provides a fixed, machine parsable internal name for the plug-in.

This name is used by Scripting Engines. MAXScript uses this name (if not null) as (one of) the global variable name(s) holding the MAXClass value which exposes this class.

Reimplemented from ClassDesc.

◆ HInstance()

virtual CoreExport HINSTANCE HInstance ( )

virtual

Returns the DLL instance handle of the plug-in.

This is used so that string resources can be loaded by the ParamBlock2 system.

Reimplemented from ClassDesc.

virtual CoreExport bool UseOnlyInternalNameForMAXScriptExposure ( )

virtual

Returns true if only the InternalName is to be used for MAXScript exposure.

For older plugins that did not previously implement InternalName but now do, MAXScript still needs to expose the plugin using the ClassName. But new plugins can be exposed using only the InternalName.

Reimplemented from ClassDesc.

This method is called by the plug-in from its Animatable::EndEditParams() method. The parameters passed to that method are simply passed along to this method.

Parameters

ip	The interface pointer passed to the plug-in.
obj	Points to the plug-in class calling this method.
flags	The flags passed along to the plug-in in Animatable::EndEditParams().
prev	The pointer passed to the plug-in in Animatable::EndEditParams().

◆ InvalidateUI()

virtual CoreExport void InvalidateUI ( ParamBlockDesc2 * pbd )

virtual

Invalidates the user interface for the rollup or dialog managed by the specified descriptor.

This will cause the controls in that rollup to be redrawn.

Parameters

pbd	Points to the parameter block 2 descriptor whose corresponding UI is invalidated.

Reimplemented from ClassDesc.

◆ GetRsrcString()

virtual CoreExport const MCHAR* GetRsrcString ( INT_PTR id )

virtual

Returns a pointer to the string from the resource string table.

Parameters

id	The resource ID.

Note: if the resource ID value is 0, a blank string is returned. If the resource ID value cannot be found, the string ">>> @!&*# <<<" is returned.

Reimplemented from ClassDesc.

◆ MakeAutoParamBlocks()

virtual CoreExport void MakeAutoParamBlocks ( ReferenceMaker * owner )

virtual

automatic ParamBlock construction

Reimplemented from ClassDesc.

◆ NumParamMaps()

virtual CoreExport int NumParamMaps ( )

virtual

access automatically-maintained ParamMaps, by simple index or by associated ParamBlockDesc

Reimplemented from ClassDesc.

◆ GetParamMap() [1/2]

virtual CoreExport IParamMap2* GetParamMap ( int i )

virtual

Returns a pointer to the nth parameter map2.

Parameters

i	The zero based index of the parameter map2 to return.

Reimplemented from ClassDesc.

◆ GetParamMap() [2/2]

virtual CoreExport IParamMap2* GetParamMap ( ParamBlockDesc2 * pbd )

virtual

Returns a pointer to the parameter map2 whose descriptor is passed.

Parameters

pbd	Points to the parameter block2 descriptor.

Reimplemented from ClassDesc.

◆ SetUserDlgProc()

virtual CoreExport bool SetUserDlgProc	(	ParamBlockDesc2 *	pbd,
		ParamMap2UserDlgProc *	proc = `NULL`
	)

virtual

maintain user dialog procs on automatically-maintained ParamMaps

Reimplemented from ClassDesc.

◆ GetUserDlgProc()

virtual CoreExport ParamMap2UserDlgProc* GetUserDlgProc ( ParamBlockDesc2 * pbd )

virtual

Returns a pointer to the parameter map 2 user dialog proc (if any) for the specified descriptor.

Parameters

pbd	Points to the parameter block 2 descriptor.

Returns: See Class ParamMap2UserDlgProc.

Reimplemented from ClassDesc.

◆ DrawRepresentation()

virtual CoreExport bool DrawRepresentation	(	COLORREF	bkColor,
		HDC	hDC,
		Rect &	rect
	)

virtual

Class can draw an image to represent itself graphically...

Reimplemented from ClassDesc.

◆ NumInterfaces()

virtual CoreExport int NumInterfaces ( )

virtual

Returns the number of function publishing interfaces maintained by the class descriptor.

Reimplemented from ClassDesc.

◆ GetInterfaceAt()

virtual CoreExport FPInterface* GetInterfaceAt ( int i )

virtual

Returns the nth function publishing interface.

Reimplemented from ClassDesc.

◆ GetInterface() [1/2]

virtual CoreExport FPInterface* GetInterface ( Interface_ID id )

virtual

Returns a pointer to the function publishing interface whose ID is specified.

Parameters

id	The inteface ID.

Reimplemented from ClassDesc.

◆ GetInterface() [2/2]

virtual CoreExport FPInterface* GetInterface ( const MCHAR * name )

virtual

Returns a pointer to the function publishing interface whose name is specified.

Parameters

name	The name of the interface.

Reimplemented from ClassDesc.

◆ AddInterface()

virtual CoreExport void AddInterface ( FPInterface * fpi )

virtual

Adds the specified interface to the list maintained by this class descriptor.

Parameters

fpi	Points to the interface to add.

Reimplemented from ClassDesc.

◆ ClearInterfaces()

virtual CoreExport void ClearInterfaces ( )

virtual

Deletes all the interfaces maintained by the class descriptor.

Reimplemented from ClassDesc.

◆ SubClassID()

virtual CoreExport Class_ID SubClassID ( )

virtual

This method can be used for further categorizing plugins.

If a plugin has sub-plugins (like light > shadows, particles > operators), this method can be used to differentiate them. sub-plugins can be derived from ReferenceTarget but return a particular class ID published by the parent plugins SDK headers. Then parent plugin can get a list of all reference targets whose SubClassID matches the published SubClassID.

Reimplemented from ClassDesc.

◆ Execute()

virtual CoreExport INT_PTR Execute	(	int	cmd,
		ULONG_PTR	arg1 = `0`,
		ULONG_PTR	arg2 = `0`,
		ULONG_PTR	arg3 = `0`
	)

virtual

This function is maintained so the 3ds Max SDK can be extended without breaking backwards compatibility.

The behavior of this function depends on the cmd parameter:

I_EXEC_CTRL_BYPASS_TREE_VIEW - Returning 1 will hide a controller in track view.
I_EXEC_GET_SOA_STATE - The arg1 parameter is expected to be a bool*. The bool gets set to true or false depending whether sub-obj anim is or not enabled for that object type. Returns TRUE if the arg1 is set successfully, otherwise FALSE.
I_EXEC_EVAL_SOA_TIME - The arg1 parameter is expected to be a TimeValue* The TimeValue gets set appropriately, depending on whether sub-obj animation is allowed of not for that object type. Returns TRUE if the arg1 is set successfully, otherwise FALSE.
