BOOL HitTest	(	IObjParam *	ip,
		HWND	hWnd,
		ViewExp *	vpt,
		IPoint2	m,
		int	flags
	)		[virtual]

Search for all occurrences

Remarks:

This method is called whenever the pick mode needs to hit test.

Parameters:

IObjParam *ip

An interface pointer available to call functions defined by 3ds Max.

HWND hWnd

The window handle.

ViewExp *vpt

An interface pointer that may be used to call methods associated with the viewports.

IPoint2 m

Point to check in screen coordinates.

int flags

Scene and Node Hit Testing Flags.

Returns:

Return TRUE if something was hit; otherwise FALSE.

Sample Code:

// This implementation use the Interface::PickNode method

// to perform the hit test.

        {
            return ip->PickNode(hWnd,m,&thePickFilt)? TRUE:FALSE;
        }

Implements PickModeCallback.

BOOL Pick	(	IObjParam *	ip,
		ViewExp *	vpt
	)		[virtual]

Search for all occurrences

Remarks:

This method is called when the user picks something.

Parameters:

IObjParam *ip

An interface pointer available to call functions defined by 3ds Max.

ViewExp *vpt

An interface pointer that may be used to call methods associated with the viewports. The vpt should have the result of the hit test in it.

Returns:

Return TRUE to end the pick mode; FALSE to stay in the pick mode. Note that returning TRUE will set the command mode to MOVE. When a plug-in is in the create branch, setting the command mode to move ends the creation process.

Implements PickModeCallback.

void EnterMode

(

IObjParam *

ip

)

[virtual]

Search for all occurrences

Remarks:

Called when the mode is entered. The developer may provide any pre-processing here.

Parameters:

IObjParam *ip

An interface pointer available to call functions defined by 3ds Max.

Reimplemented from PickModeCallback.

void ExitMode

(

IObjParam *

ip

)

[virtual]

Search for all occurrences

Remarks:

Called when the mode is exited. The developer may provide any post-processing here.

Parameters:

IObjParam *ip

An interface pointer available to call functions defined by 3ds Max.

Reimplemented from PickModeCallback.

HCURSOR GetHitCursor

(

IObjParam *

ip

)

[virtual]

Search for all occurrences

Remarks:

Called to get the hit test cursor to use.

Returns:

The handle of the hit test cursor.

Default Implementation:

{return NULL;}

Reimplemented from PickModeCallback.

BOOL Filter

(

INode *

node

)

[virtual]

Search for all occurrences

Remarks:

This method should return TRUE if the node passed is an acceptable hit and FALSE otherwise.

Parameters:

INode *node

The node to test.

Returns:

Return TRUE if this is an acceptable hit, FALSE otherwise.

Implements PickNodeCallback.

PickNodeCallback* GetFilter

(

)

[inline, virtual]

Search for all occurrences

Remarks:

This method is called if the user hits the H key while in your pick mode. You can provide a filter to filter the name list. See Class PickNodeCallback.

Returns:

A pointer to an instance of PickNodeCallback.

Default Implementation:

{return NULL;}

Reimplemented from PickModeCallback.

{return this;}

BOOL RightClick	(	IObjParam *	ip,
		ViewExp *	vpt
	)		[inline, virtual]

Search for all occurrences

Remarks:

This method is called when the user right-clicks or presses ESC.

Parameters:

IObjParam *ip

An interface pointer available to call functions defined by 3ds Max.

ViewExp *vpt

An interface pointer that may be used to call methods associated with the viewports. The vpt should have the result of the hit test in it.

Returns:

TRUE to end the pick mode, FALSE to continue picking.

Default Implementation:

{ return FALSE; }

Reimplemented from PickModeCallback.

{ UNUSED_PARAM(ip); UNUSED_PARAM(vpt); return TRUE;}
