pymel.core.general.itemFilterAttr

itemFilterAttr(*args, **kwargs)

This command creates a named itemFilterAttr object. This object can be attached to editors, in order to filter the attributes going through them. Using union and intersection filters, complex composite filters can be created.

Flags:

Long name (short name)		Argument Types	Properties
byName (bn)		unicode
	The filter will only pass items whose names match the given regular expression string. This string can contain the special characters * and ?. ‘?’ matches any one character, and ‘*’ matches any substring.
byNameString (bns)		unicode
	The filter will only pass items whose names match the given string. This is a multi-use flag which allows the user to specify several strings. The filter will pass items that match any of the strings.
byScript (bs)		unicode
	The filter will run a MEL script named by the given string on each attribute name. Attributes will pass the filter if the script returns a non-zero value. The script name string must be the name of a proc whose signature is:global proc int procName( string $nodeName string $attrName )
classification (cls)		unicode
	Internal use only. Indicates whether the filter is a built-in or user filter. The string argument is one of “builtIn” | “user” | “other”.
dynamic (dy)		bool
exists (ex)		bool
hasCurve (hc)		bool
	The filter will only pass attributes that are driven by animation curves.
hasDrivenKey (hdk)		bool
	The filter will only pass attributes that are driven by driven keys
hasExpression (he)		bool
	The filter will only pass attributes that are driven by expressions
hidden (h)		bool
	The filter will only pass attributes that are hidden to the user
intersect (intersect)		unicode, unicode
	The filter will consist of the intersection of two other filters, whose names are the given strings. Attributes will pass this filter if and only if they pass both of the contained filters.
keyable (k)		bool
	The filter will only pass attributes that are keyable
listBuiltInFilters (lbf)		bool
	Returns an array of all attribute filters with classification “builtIn”.
listOtherFilters (lof)		bool
	Returns an array of all attribute filters with classification “other”.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
listUserFilters (luf)		bool
	Returns an array of all attribute filters with classification “user”.
negate (neg)		bool
	This flag can be used to cause the filter to invert itself, and reverse what passes and what fails.
parent (p)		unicode
	This flag is no longer supported.
published (pub)		bool
	The filter will only pass attributes that are published on the container.
readable (r)		bool
	The filter will only pass attributes that are readable (outputs)
scaleRotateTranslate (srt)		bool
	The filter will show only SRT attributes: scale, rotate, translate and their children
secondScript (ss)		unicode
	Can be used in conjunction with the -bs flag. The second script is for filtering whole lists at once, rather than individually. Its signature must be:global proc string[] procName( string[] $nodeName string[] $attrName )It should take in a list of attributes, and return a filtered list of attributes.
text (t)		unicode
	Defines an annotation string to be stored with the filter
union (un)		unicode, unicode
	The filter will consist of the union of two other filters, whose names are the given strings. Attributes will pass this filter if they pass at least one of the contained filters.
writable (w)		bool
	The filter will only pass attributes that are writable (inputs)

Derived from mel command maya.cmds.itemFilterAttr

Example:

import pymel.core as pm

import maya.cmds as cmds

#    Create a filter that will pass all the SRT (scale-rotate-translate)
#    attributes.
#
srtFilter = pm.itemFilterAttr('itemFilterAttr', scaleRotateTranslate=True)

#    Create a filter that will pass all the attributes driven by an
#    expression.
#
exprFilter = pm.itemFilterAttr(hasExpression=True)

#    Create a filter that will pass all the SRT attributes driven by an
#    expression (intersect two previous ones).
#
srtExprFilter = pm.itemFilterAttr(intersect=(srtFilter, exprFilter))

#    Delete the filters when done with them.
#
pm.delete( srtFilter, exprFilter, srtExprFilter )
