pymel.core.context.scriptCtx

scriptCtx(*args, **kwargs)

This command allows a user to create their own tools based on the selection tool. A number of selection lists can be collected, the behaviour of the selection and the selection masks are fully customizable, etc. The command is processed prior to being executed. The keyword “$Selection#” where # is a number 1 or greater specifies a selection set. The context can specify several selection sets which are substituted in place of the $Selection# keyword in the form of a Mel string array. Items that are specific per set need to be specified in each set, if they are going to be specified for any of the sets. See examples below. In addition, in order to specify the type of selection you need to be making, any of the selection type flags from “selectType” command can be used here.

Flags:

Long name (short name)		Argument Types	Properties
allComponents (alc)		bool
allObjects (alo)		bool
animBreakdown (abd)		bool
animCurve (ac)		bool
animInTangent (ait)		bool
animKeyframe (ak)		bool
animOutTangent (aot)		bool
baseClassName (bcn)		unicode
	This string will be used to produce MEL function names for the property sheets for the tool. For example, if “myScriptTool” was given, the functions “myScriptToolValues” and “myScriptToolProperties” will be used for the property sheets. The default is “scriptTool”.
byName (bn)		unicode, int
camera (ca)		bool
cluster (cl)		bool
collisionModel (clm)		bool
controlVertex (cv)		bool
cumulativeLists (cls)		bool
	If set, the selection lists will be cumulative. For example, the second list will contain all the items from the first list, the third all the items from the second list etc. Make sure your script specified above takes that into account. Relevant if there is more than one selection set.
curve (c)		bool
curveKnot (ck)		bool
curveOnSurface (cos)		bool
curveParameterPoint (cpp)		bool
dimension (dim)		bool
dynamicConstraint (dc)		bool
edge (eg)		bool
editPoint (ep)		bool
emitter (em)		bool
enableRootSelection (ers)		bool
	If set, the items to be selected are at their root transform level. Default is false.
exists (ex)		bool
exitUponCompletion (euc)		bool
	If set, completing the last selection set will exit the tool. Default is true.
expandSelectionList (esl)		bool
	If set, the selection lists will expand to have a single component in each item. You probably want this as a default, otherwise two isoparms on the same surface will show up as 1 item. To ensure that components on the same object are returned in the order in which they are selected, use the selectPref -trackSelectionOrder oncommand in your -toolStartscript to enable ordered selection, then restore it to its original value in your -toolFinishscript.
facet (fc)		bool
field (fi)		bool
finalCommandScript (fcs)		script
	Supply the script that will be run when the user presses the enter key and the context is completed. Depending on the number of selection sets you have, the script can make use of variables string $Selection1[], $Selection2[], ...
fluid (fl)		bool
follicle (fo)		bool
forceAddSelect (fas)		bool
	If set to true, together with -setAutoToggleSelection (see below) on the first selection set, causes the first selection after the computation of the previous result to be “shift” selection, unless a modifier key is pressed. Default is false. Flags for each selection set. These flags are multi-use.
hairSystem (hs)		bool
handle (ha)		bool
history (ch)		bool
hull (hl)		bool
ignoreInvalidItems (iii)		bool
	If you have multiple selection sets, the state of the selection set is recorded at the time you “complete it”. You could then delete some of the items in that list and end up with invalid items in one or more of your selection sets. If this flag is set, those items will be detected and ignored. You will never know it happened. Its as if they were never selected in the first place, except that your selection set now does not have as many items as it may need. If this flag is not set, you will get a warning and your final command callback script will likely not execute because of an error condition.
ikEndEffector (iee)		bool
ikHandle (ikh)		bool
image1 (i1)		unicode
image2 (i2)		unicode
image3 (i3)		unicode
imagePlane (ip)		bool
implicitGeometry (ig)		bool
isoparm (iso)		bool
joint (j)		bool
jointPivot (jp)		bool
lastAutoComplete (lac)		bool
	True if auto complete is set for the last selection set, false otherwise. Mostly used for query, but if present in conjuction with -sac/setAutoComplete flag, -sac flag takes precedence.

sculpt (sc)		bool
selectHandle (sh)		bool
setAllowExcessCount (sae)		bool
	If set, the number if items is to be interpreted as the minimum.
setAutoComplete (sac)		bool
	If set to true, as soon as the specified number of items is selected the tool will start the next selection set or run the command.
setAutoToggleSelection (sat)		bool
	If set to true, it is as if “shift” key is pressed when there are no modifiers pressed. That means that you get the “toggle select” behaviour by default. This only applies to the 3D view, and the selection done in the hypergraph, outliner or elsewhere is still a subject to the usual rules.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
setDoneSelectionPrompt (dsp)		unicode
	If setAutoComplete is not set (see below) this string will be shown as soon as the tool has enough items for a particular selection set. If this is not set, but is needed, the same string as set with -setSelectionPrompt flag will be used.
setNoSelectionHeadsUp (snh)		unicode
	Supply a string that will be shown as a heads up prompt when there is nothing selected. This must be set separately for each selection set.
setNoSelectionPrompt (snp)		unicode
	Supply a string that will be shown as help when there is nothing selected. This must be set separately for each selection set.
setSelectionCount (ssc)		int
	The number of items in this selection set. 0 means as many as you need until completion.
setSelectionHeadsUp (ssh)		unicode
	Supply a string that will be shown as a heads up prompt when there is something selected. This must be set separately for each selection set.
setSelectionPrompt (ssp)		unicode
	Supply a string that will be shown as help when there is something selected. This must be set separately for each selection set.

	Supply a string that will be used as a precursor to all the messages; i.e., the “name” of the tool.
toolCursorType (tct)		unicode
	Supply the string identifier to set the tool cursor type when inside of tool. The following are the valid ids: “create”, “dolly”, “edit”, “pencil”, “track”, “trackHorizontal”, “trackVertical”, “transformation”, “tumble”, “zoom”, “zoomIn”, “zoomOut”, “flyThrough”, “dot”, “fleur”, “leftArrow”, “question”, “doubleHorizArrow”, “doubleVertArrow”, “sizing”, “dollyIn”, “dollyOut”, “brush”, “camera”, “noAccess”, “input”, “output”, “leftCycle”, “rightCycle”, “rightExpand”, “knife”.

Derived from mel command maya.cmds.scriptCtx

Example:

import pymel.core as pm

# Simple example of "attach curve" tool created using scriptCtx. This tool
# prompts the user to select two curves to attach. As soon as two curves
# are selected, the attach is performed. It uses the selection type
# flag 'curveParameterPoint' from "selectType" command to specify the
# selection mask for this tool.

pm.scriptCtx( title='Attach Curve', totalSelectionSets=1, fcs="select -r $Selection1; performAttachCrv 0 \"\"", cumulativeLists=True, expandSelectionList=True, setNoSelectionPrompt='Select two curves close to the attachment points', setSelectionPrompt='Select a second curve close to the attachment point', setDoneSelectionPrompt='Never used because setAutoComplete is set', setAutoToggleSelection=True, setSelectionCount=2, setAutoComplete=True, curveParameterPoint=True )
# Result: u'scriptCtx1' #

# And a more complex example of fillet blend tool (two sets of any number
# of "surface curves").  Notice how the selection lists are passed as
# arguments to the callback function, performBlendGiven.

pm.scriptCtx( i1='birail3Gen.xpm', title='"Birail 3+ Tool', toolCursorType='edit', totalSelectionSets=2, cumulativeLists=True, expandSelectionList=True, fcs='select -r $Selection2; performBirail 0 3 \"birailThreePlusProfileContext\" ', setAutoToggleSelection=[True,True], setAutoComplete=[False, False], setSelectionCount=[0,2], nurbsCurve=[True,True], isoparm=[True,True], curveOnSurface=[True,True], surfaceEdge=[True,True], polymeshEdge=[True,True], setNoSelectionPrompt=['Select any number of profiles','Select two rails'], setSelectionPrompt=['Select additional profiles or hit ENTER', 'Select the second rail'], setDoneSelectionPrompt=['Profiles selected. Hit ENTER to start rail selection.', 'Rails selected. Hit ENTER to compute birail. '] )
# Result: u'scriptCtx2' #

# Here's Birail 3+ where you select any number of curves, then 2 rails:

pm.scriptCtx( i1='birail3Gen.xpm', title='"Birail 3+ Tool', toolCursorType='edit', totalSelectionSets=2, cumulativeLists=True, expandSelectionList=True, fcs='select -r $Selection2; performBirail 0 3 \"birailThreePlusProfileContext\" ', setAutoToggleSelection=[True,True], setAutoComplete=[False, False], setSelectionCount=[0,2], nurbsCurve=[True,True], isoparm=[True,True], curveOnSurface=[True,True], surfaceEdge=[True,True], polymeshEdge=[True,True], setNoSelectionPrompt=['Select any number of profiles','Select two rails'], setSelectionPrompt=['Select additional profiles or hit ENTER', 'Select the second rail'], setDoneSelectionPrompt=['Profiles selected. Hit ENTER to start rail selection.', 'Rails selected. Hit ENTER to compute birail. '] )
# Result: u'scriptCtx3' #

# userBirailContextCallback has "true" as the first argument, which suggests
# that $Selection2 contains all of $Selection1 items (as -cumulativeLists
# true is specified in the tool creation.)
