fullyQualifiedName(channel=- 1) string

Returns the fully-qualified name of the knob within the node. This can be useful for expression linking.

Parameters

channel – Optional parameter, specifies the channel number of the sub-knob (for example, channels of 0 and 1 would refer to the x and y of a XY_Knob respectively), leave blank or set to -1 to get the qualified name of the knob only.

Returns

The string of the qualified knob or sub-knob, which can be used directly in expression links.

getAuthorMode() Integer.

Returns the authoring mode currently set on the knob. This is a unique string identifier of the option, which is also used for serialisation and deserialisation. It is not meant to change,thus one can rely on it. :return: The string identifier of the current authoring mode set.

getAuthorModes() List.

Returns the names of the authoring modes of the knob if the knob is an authoring knob, otherwise an empty list. :return: The names of the authoring modes of the knob if the knob is an authoring knob, otherwise an empty list. This is a list of strings.

getDerivative()

Return derivative at time ‘t’ for channel ‘c’.

getFlag(f) Bool.

Returns whether the input flag is set. :param f: Flag. :return: True if set, False otherwise.

getIntegral()

Return integral at the interval [t1, t2] for channel ‘c’.

getKeyIndex()

Return keyframe index at time ‘t’ for channel ‘c’.

getKeyList()

Get all unique keys on the knob. Returns list.

getKeyTime()

Return index of the keyframe at time ‘t’ for channel ‘c’.

getNthDerivative()

Return nth derivative at time ‘t’ for channel ‘c’.

getNumKeys()

Return number of keyframes for channel ‘c’.

getValue()

Return value at the current frame for channel ‘c’.

getValueAt()

Return value at time ‘t’ for channel ‘c’.

hasExpression(index=- 1) bool

Return True if animation at index ‘index’ has an expression. :param index: Optional index parameter. Defaults to -1 if not specified. This can be specified as a keyword parameter if desired. :return: True if has expression, False otherwise.

isAnimated()

Return True if channel ‘c’ is animated.

isKey()

Return True if there is a keyframe at the current frame for channel ‘c’.

isKeyAt()

Return True if there is a keyframe at time ‘t’ for channel ‘c’.

label() label.
Returns

label.

name() name.
Returns

name.

node() nuke.Node

Return the node that this knob belongs to. If the node has been cloned, we’ll always return a reference to the original. :return: The node which owns this knob, or None if the knob has no owner yet.

removeKey()

Remove key for channel ‘c’. Return True if successful.

removeKeyAt()

Remove key at time ‘t’ for channel ‘c’. Return True if successful.

setAnimated()

Set channel ‘c’ to be animated.

setAuthorMode(authorMode) None.

Sets the authoring mode on the knob. This accepts both the unique string identifier, which is also used for serialisation and deserialisation, or index of the option for convenience. These values are not meant to change, thus one can rely on them. :param authorMode: The string identifier or index of the authoring mode. :return: None.

setEnabled(enabled) None.

Enable or disable the knob. :param enabled: True to enable the knob, False to disable it.

setExpression(expression, channel=- 1, view=None) bool

Set the expression for a knob. You can optionally specify a channel to set the expression for.

Parameters
  • expression – The new expression for the knob. This should be a string.

  • channel – Optional parameter, specifying the channel to set the expression for. This should be an integer.

  • view – Optional view parameter. Without, this command will set the expression for the current view theinterface is displaying. Can be the name of the view or the index.

Returns

True if successful, False if not.

setFlag(f) None.

Logical OR of the argument and existing knob flags. :param f: Flag. :return: None.

setLabel(s) None.
Parameters

s – New label.

Returns

None.

setName(s) None.
Parameters

s – New name.

Returns

None.
