Synopsis

channelBox [flags] [boxName]

This command creates a channel box, which is sensitive to the active list. It displays certain attributes (channels) of the last node on the active list, and provides a two-way connection to keep the widget up to date.

Return value

string (the name of the new channel box)

Long name (short name)[argument types]Properties
-query (-q) query
Puts the command in query mode so that it will return the value of the specified flag.
-edit (-e) edit
Puts the command in edit mode so that it will change the values of the specified flags
-exists (-ex) create
Returns true|false depending upon whether the specified object exists. Other flags are ignored.
-defineTemplate (-dt) stringcreate
Puts a command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template.
-useTemplate (-ut) stringcreate
Will force the command to use a command template other than the current one.
-parent (-p) stringcreate
The parent layout for this control.
-enable (-en) booleanquerycreateedit
The enable state of the control. By default, this flag is set to true and the control is enabled. Specify false and the control will appear dimmed or greyed-out indicating it is disabled.
-width (-w) intquerycreateedit
The width of the control. The control will attempt to be this size if it is not overruled by parent layout conditions.
-height (-h) intquerycreateedit
The height of the control. The control will attempt to be this size if it is not overruled by parent layout conditions.
-visible (-vis) booleanquerycreateedit
The visible state of the control. A control is created visible by default. Note that a control's actual appearance is also dependent on the visible state of its parent layout(s).
-isObscured (-io) query
Return whether the control can actually be seen by the user. The control will be obscured if its state is invisible, if it is blocked (entirely or partially) by some other control, if it or a parent layout is unmanaged, or if the control's window is invisible or iconified.
-manage (-m) booleanquerycreateedit
Manage state of the control. An unmanaged control is not visible, nor does it take up any screen real estate. All controls are created managed by default.
-numberOfPopupMenus (-npm) query
Return the number of popup menus attached to this control.
-popupMenuArray (-pma) query
Return the names of all the popup menus attached to this control.
-preventOverride (-po) booleanquerycreateedit
If true, this flag disallows overriding the control's attribute via the control's right mouse button menu.
-annotation (-ann) stringquerycreateedit
Annotate the control with an extra string value.
-backgroundColor (-bgc) float float floatcreateedit
The background color of the control. The arguments correspond to the red, green, and blue color components. Each component ranges in value from 0.0 to 1.0. (Windows only flag)
-docTag (-dt) querycreateedit
Add a documentation flag to the control. The documentation flag has a directory structure like hierarchy. Eg. -dt render/multiLister/createNode/material
-dragCallback (-dgc) stringcreateedit
Adds a callback that is called when the middle mouse button is pressed. The callback is of the form:

global proc string[] callbackName(string $dragControl, int $x, int $y, int $mods)

The proc returns a string array that is transferred to the drop site. By convention the first string in the array describes the user settable message type. Controls that are application defined drag sources may ignore the callback. $mods allows testing for the key modifiers CTL and SHIFT. Possible values are 0 == No modifiers, 1 == SHIFT, 2 == CTL, 3 == CTL + SHIFT.

-dropCallback (-dpc) stringcreateedit
Adds a callback that is called when a drag and drop operation is released above the drop site. The callback is of the form:

global proc callbackName(string $dragControl, string $dropControl, string $msgs[], int $x, int $y, int $type)

The proc receives a string array that is transferred from the drag source. The first string in the msgs array describes the user defined message type. Controls that are application defined drop sites may ignore the callback. $type can have values of 1 == Move, 2 == Copy, 3 == Link.

-precision (-pre) intqueryedit
Controls the number of digits to the right of the decimal point that will be displayed for float-valued channels. Default is 3. Queried, returns an int.
-longNames (-ln) booleanqueryedit
Controls whether long or short attribute names will be used in the interface. Note that this flag is ignored if the -niceNames flag is set. Default is short names. Queried, returns a boolean.
-niceNames (-nn) booleanqueryedit
Controls whether the attribute names will be displayed in a more user-friendly, readable way. When this is on, the longNames flag is ignored. When this is off, attribute names will be displayed either long or short, according to the longNames flag. Default is on. Queried, returns a boolean.
-attributeEditorMode (-aem) booleanqueryedit
Modifies what appears in the channel box for use in the attribute editor. Default is false. Queried, returns a boolean.
-enableLabelSelection (-els) booleanqueryedit
Enables the selection of attributes in the channelBox when used in conjunction with -attributeEditorMode. Default is false. Queried, returns a boolean.
-maxWidth (-mw) intqueryedit
An optional flag which is used to limit the width of the channelBox.
-maxHeight (-mh) intqueryedit
An optional flag which is used to limit the height of the channelBox.
-labelWidth (-lw) intqueryedit
An optional flag which is used to modify the width assigned to labels appearing in the channelBox.
-fieldWidth (-fw) intqueryedit
An optional flag which is used to modify the width assigned to fields appearing in the channelBox.
-showTransforms (-st) booleanqueryedit
Controls whether this control will display transform attributes only, or all other attributes. False by default. Queried, returns a boolean.
-mainObjectList (-mol) query
Returns a list of strings, the names of every object on the active list that is the same type as the object displayed in the top (main) section of the channel box.
-shapeObjectList (-sol) query
Returns a list of strings, the names of every shape associated with an object on the main object list that is of the same type as the object displayed in the middle (shape) section of the channel box.
-historyObjectList (-hol) query
Returns a list of strings, the names of every INPUT node associated with an object on the main object list that is of the same type as the node displayed in the INPUT section of the channel box.
-OutputObjectList (-ool) query
Returns a list of strings, the names of every OUTPUT node associated an object on the main object list that is of the same type as the node displayed in the OUTPUT section of the channel box.
-selectedMainAttributes (-sma) query
Returns a list of strings, the names of all the selected attributes in the top section of the channel box.
-selectedShapeAttributes (-ssa) query
Returns a list of strings, the names of all the selected attributes in the middle (shape) section of the channel box.
-selectedHistoryAttributes (-sha) query
Returns a list of strings, the names of all the selected attributes in the INPUT section of the channel box.
-selectedOutputAttributes (-soa) query
Returns a list of strings, the names of all the selected attributes in the OUTPUT section of the channel box.
-execute (-exe) string booleanedit
Immediately executes the command string once for every cell (or every selected cell, if the boolean argument is TRUE) in the channel box, for every matching selected object (ie, for every object would be affected if you changed a cell value.) Before the command is executed, "#A" is substituted with the name of the attribute, and "#N" with the name of the node, and "#P" with the full path name of the node.
-mainListConnection (-mlc) stringquerycreateedit
Specifies the name of a selectionConnection object which the editor will use as its source of content. The channel box will only display the (last) item contained in the selectionConnection object. If a NULL string ("") is specified, then the channel box will revert to its default behaviour of working on the active list.
-fixedAttrList (-fal) {"attrName1","attrName2",etc}querycreateedit
Forces the channel box to only display attributes with the specified names, in the order they are specified. If an empty list is specified, then the channel box will revert to its default behaviour of listing all keyable attributes.
-useManips (-mnp) stringquerycreateedit
When you click on a field or label in the channel box, the tool switches to a manipulator that can change that value if you drag in the 3d view. This flag controls the kind of manips. Allowed values are "none" (self-explanatory), "invisible" (you won't see anything, but dragging in the window will adjust any of the selected attributes), and "standard" (the same as invisible, except for scale, rotate, and translate, which will be represented by their usual manips.)
-takeFocus (-tf) edit
causes the channel box to take over the keyboard focus, if it can.
-hyperbolic (-hyp) booleanquerycreateedit
Determines whether or not the distance that the mouse has been dragged should be interpreted as a linear or hyperbolic function. The default is set to hyperbolic being false.
-speed (-spd) floatquerycreateedit
Controls the speed at which the attributes are changed based on the distance the mouse has been dragged. Common settings for slow/medium/fast are 0.1/1.0/10.0 respectively. The default is 1.0.
-showNamespace (-sn) booleanquerycreateedit
Controls whether or not the namespace of an object is displayed if the object is not in the root namespace.
