Class IKeyControl, Class Interface.

Description:

The track bar offers a quick way to manipulate keyframes for selected objects. Keys are displayed on the track bar just like they are in Track View. Developers are able to manipulate the track bar using this class. There is a method of class Interface which returns a pointer to an instance of this class:

ITrackBar* GetTrackBar().

All methods of this class are Implemented by the System.

Member Function Documentation

SetVisible()

virtual void SetVisible ( BOOL  bVisible )

pure virtual

Remarks

Sets the visibility of the track bar to on or off.

Parameters:

BOOL bVisible

TRUE to make visible; FALSE to hide.

IsVisible()

virtual BOOL IsVisible ( )

pure virtual

Remarks

Returns TRUE if the track bar is visible; otherwise FALSE.

SetFilter()

virtual void SetFilter ( UINT  nFilter )

pure virtual

Remarks

The track bar shows keys for all parametric animation as well as transforms. This method sets the filter used which determines which keys are shown in the track bar.

Parameters:

UINT nFilter

One of the following values:

TRACKBAR_FILTER_ALL

Specifies to show all keys.

TRACKBAR_FILTER_TMONLY

Specifies to show transform keys only.

TRACKBAR_FILTER_CURRENTTM

Specifies to only show keys for the currently active transform (move, rotate or scale).

TRACKBAR_FILTER_OBJECT

Specifies to show keys for the controllers assigned anywhere in the pipeline to be included in the TrackBar key-display. This is essentially the modifiers and the base objects for the selected nodes (no transforms or materials).

TRACKBAR_FILTER_MATERIAL

Specifies to show keys for the controllers assigned anywhere for the selected nodes material - all controllers in the whole material tree will be included in the track bar display.

GetFilter()

virtual UINT GetFilter ( )

pure virtual

Remarks

Returns the filter value which determines which keys are shown in the track bar. See the list specified in the method above for details.

GetNextKey()

virtual TimeValue GetNextKey ( TimeValue  tStart, BOOL  bForward  )

pure virtual

Remarks

This method returns the time of the next key given a start time and a flag which indicates if the search should proceed forward or backwards. This is similar to the behavior of Animatable::GetNextKeyTime().

Parameters:

TimeValue tStart

Specifies the time to start looking for the next key.

BOOL bForward

TRUE to return the time of the next key; FALSE for the previous key.

Returns

The time of the next (or previous) key.

RedrawTrackBar()

virtual void RedrawTrackBar ( bool  bForce = false )

pure virtual

Remarks

Redraws the Track Bar if required an optionally forces a redraw (even if not known to be required).

Parameters:

bool bForce = false

Pass true to force a redraw; false to only redraw if 3ds Max deems it required.

SetShowFrames()

virtual void SetShowFrames ( bool  b )

pure virtual

Remarks

Controls the visibility of frame numbers in the Track Bar.

Parameters:

bool b

Pass true to show frame numbers; false to turn them off.

GetShowFrames()

virtual bool GetShowFrames ( )

pure virtual

Remarks

Returns true if frame numbers are visible in the Track Bar; false if not.

SetShowAudio()

virtual void SetShowAudio ( bool  b )

pure virtual

Remarks

Controls the visibility of the audio track.

Parameters:

bool b

Pass true to show the audio track; false to turn it off.

GetShowAudio()

virtual bool GetShowAudio ( )

pure virtual

Remarks

Returns true if the audio track is displayed; false if it is not.

SetShowSelectionRange()

virtual void SetShowSelectionRange ( bool  b )

Remarks

Controls if the selection range bar is visible or not.

Parameters:

bool b

Pass true to display the selection range bar; false to turn it off.

GetShowSelectionRange()

virtual bool GetShowSelectionRange ( )

pure virtual

Remarks

Returns true if the selection range bar is visible; false if it is not.

SetSnapToFrames()

virtual void SetSnapToFrames ( bool  b )

pure virtual

Controls the snap to frames setting.

Parameters:

bool b

Pass true to turn it on; false to turn it off.

GetSnapToFrames()

virtual bool GetSnapToFrames ( )

pure virtual

Remarks

Returns true if snap to frames is on; false if it is off.

SetKeyTransparency()
