channelBox is undoable, queryable, and editable.
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.
Note: when setting the color of attribute names, that color is only valid
for its current Maya session; each subsequent session will display the default
color for the attribute name(s) listed in the Channel Box. Any subsequent
attributes that are added to the Channel Box will be affected by prior
regular expressions in their current Maya session.
In query mode, return type is based on queried flag.

Argument types |
Properties |
exists(ex)
|
boolean
|
|
|
Returns true|false depending upon whether the
specified object exists. Other flags are ignored.
|
|
defineTemplate(dt)
|
string
|
|
|
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)
|
string
|
|
|
Force the command to use a command template other than
the current one.
|
|
parent(p)
|
string
|
|
|
The parent layout for this control.
|
|
enable(en)
|
boolean
|
|
|
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)
|
int
|
|
|
The width of the control. The control will attempt to
be this size if it is not overruled by parent layout conditions.
|
|

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)
|
boolean
|

to the red, green, and blue color components. Each component ranges
in value from 0.0 to 1.0.
When setting backgroundColor, the background is automatically
enabled, unless enableBackground is also specified with a false
value.
|
|
noBackground(nbg)
|
boolean
|
|
|
Clear/reset the control's background.
Passing true means the background should not be drawn at all, false means the background should be drawn. The state of this flag is inherited by children of this control.

|
boolean
|
|
|
Enables the background color of the control.
|
|
docTag(dtg)
|
string

Add a documentation flag to the control. The documentation flag
has a directory structure like hierarchy.
Eg. -dt render/multiLister/createNode/material
|
|
dragCallback(dgc)
|
script
|
|
|
Adds a callback that is called when the middle mouse button
is pressed. The MEL version of 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.
In Python, it is similar, but there are two ways to specify the callback. The
recommended way is to pass a Python function object as the argument. In that
case, the Python callback should have the form:
def callbackName( dragControl, x, y, modifiers ):
The values of these arguments are the same as those for the MEL version above.
The other way to specify the callback in Python is to specify a string to be
executed. In that case, the string will have the values substituted into it
via the standard Python format operator. The format values are passed in a
dictionary with the keys "dragControl", "x", "y", "modifiers". The
"dragControl" value is a string and the other values are integers (eg the
callback string could be "print '%(dragControl)s %(x)d %(y)d %(modifiers)d'")
|
|
dropCallback(dpc)
|
script
|
|
|
Adds a callback that is called when a drag and drop
operation is released above the drop site. The MEL version of 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.
In Python, it is similar, but there are two ways to specify the callback. The
recommended way is to pass a Python function object as the argument. In that
case, the Python callback should have the form:
def pythonDropTest( dragControl, dropControl, messages, x, y, dragType ):
The values of these arguments are the same as those for the MEL version above.
The other way to specify the callback in Python is to specify a string to be
executed. In that case, the string will have the values substituted into it
via the standard Python format operator. The format values are passed in a
dictionary with the keys "dragControl", "dropControl", "messages", "x", "y",
"type". The "dragControl" value is a string and the other values are integers
(eg the callback string could be
"print '%(dragControl)s %(dropControl)s %(messages)r %(x)d %(y)d %(type)d'")

|
|
niceNames(nn)
|
boolean
|
|
|
Controls whether the attribute names will be displayed in
a more user-friendly, readable way. When this is on, the longNames

either long or short, according to the longNames flag.
Default is on. Queried, returns a boolean.
|
|
attributeEditorMode(aem)

execute(exe)
|
[string, boolean]
|
|
|
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)
|
string
|
|
|
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)
|
[string,...]
|
|
|
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)
|
string
|
|
|
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)
|
boolean
|
|
|
causes the channel box to take over the keyboard focus, if it can.
|
|
hyperbolic(hyp)
|
boolean

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)
|
float
|
|
|
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)
|
boolean
|
|
|
Controls whether or not the namespace of an object is displayed
if the object is not in the root namespace.
|
|
attrColor(ac)
|
[float, float, float]
|
|
|
Controls the foreground text color of specific attribute names. This
text coloring also depends on the node name choice for the nodeRegex flag.
Arguments correspond to the red, green, and blue color components.
Each component ranges in value from 0.0 to 1.0. If attrRegex is
unspecified then it will assume a value of "*" for a regular expression.
The same idea simultaneously applies to the flag nodeRegex.
Note: nodes that are renamed will have their node name coloring be affected
in the channel box.
|
|
attrBgColor(bc)
|
[float, float, float]
|
|
|
Controls the background text color of specific attribute names. As with the foreground
option, this text coloring also depends on the node name choice for the nodeRegex flag.
Arguments correspond to the red, green, and blue color components.
Each component ranges in value from 0.0 to 1.0. If attrRegex is
unspecified then it will assume a value of "*" for a regular expression.
The same idea simultaneously applies to the flag nodeRegex.
Note: nodes that are renamed will have their node name coloring be affected
in the channel box.
|
|
nodeRegex(nr)
|
string
|
|
|
Specifies a valid regular expression to specify which node names should
(potentially) have their attributes selected for foreground text coloring.
If nodeRegex is unspecified then it will assume a value of "*' for a
regular expression. The same idea simultaneously applies to the flag
attrRegex. The attrColor flag is required to be specified.
Note: this regular expression will be treated as though it were case-insensitve
Note: nodes in namespaces have regular expressions applied as though those
nodes weren't in namespaces
|
|
attrRegex(ar)
|
string
|
|
|
Specifies a valid regular expression to specify which attribute names
should be selected for foreground text coloring. If attrRegex is
unspecified then it will assume a value of "*" for a regular expression.
The same idea simultaneously applies to the flag nodeRegex.
The attrColor flag is required to be specified.
Note: this regular expression will be treated as though it were case-insensitve
|
|
update(u)
|
boolean
|
|
|
This flag can be used to force an update of the channel box display, for
example after changing a display preference.
|
|
attrFilter(af)
|
string
|
|
|
Specifies the name of an itemFilter object to be placed on the channel box.
This filters the attributes displayed. A filter of "0" can be used to reset the
filter.

|
This flag can be used to specify whether or not the container is drawn at the
top of the channel box when a node in the container is selected.
|
|
Flag can have multiple arguments, passed either as a tuple or a list.
