layerButton is undoable, queryable, and editable.
Creates a layer bar button widget. This widget contains both the name of
the layer to which it refers and a color swatch indicating it's color
assignment. It is used primarily in the construction of the layerBar
and layer Editor window, being the widget used for each layer in the
respective lists.
In query mode, return type is based on queried flag.

Argument types |
Properties |
|
annotation(ann)
|
string
|
  
|
|
Annotate the control with an extra string value.
|
|
backgroundColor(bgc)
|
[float, float, float]
|
|
|
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.
When setting backgroundColor, the background is automatically
enabled, unless enableBackground is also specified with a false
value.
|
|
changeCommand(cc)
|
script
|
|
|
Set the command to call on a change of any kind.
|
|
color(cl)
|
[float, float, float]
|
|
|
Layer color, specified with normalized real numbers in R, G,
B space.
|
|
command(c)
|
script
|
|
|
Set the command to call on a single click.
|
|
current(cr)
|
boolean
|
|
|
Set this button to display as the current layer. The current
layer is the one which the user has the option of adding all newly
created objects into. NB: Setting the layer button to this state
has no effect on the actual current layer.
|
|
defineTemplate(dt)
|
string
|
|
|
Puts the command in a mode where any other flags and arguments 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.
|
|
docTag(dtg)
|
string
|
|
|
Add a documentation flag to the control. The documentation flag
has a directory structure.
(e.g., -dt render/multiLister/createNode/material)
|
|
doubleClickCommand(dcc)
|
script
|
|
|
Set the command to call on a double click.
|
|
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 CTRL and
SHIFT. Possible values are 0 == No modifiers, 1 == SHIFT, 2 == CTRL,
3 == CTRL + 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'")
|
|
enable(en)
|
boolean
|

enableKeyboardFocus(ekf)
|
boolean

If enabled, the user can navigate to the control with the tab key and select values with the keyboard or mouse.
This flag would typically be used to turn off focus support from controls that get it by default, like Edit and List controls.
If disabled, text in text fields can still be selected with the mouse but cannot be copied (except on Linux when "Middle Click Paste" is enabled).
|

parent layout is unmanaged, or if the control's window is
invisible or iconified.
