shelfButton is undoable, queryable, and editable.

This command creates an iconTextButton that is designed to be on the shelf. The button contains a command that can be drag'n'dropped.

Return value

In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
-align(-al)	string
The label alignment. Alignment values are "left", "right", and "center". By default, the label is aligned "center". Currently only available when -st/style is set to "iconAndTextCentered".
-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.
-command(-c)	script
Command executed when the control is pressed.
-commandRepeatable(-rpt)	boolean
Set if the MEL command specified in the command flag should be repeatable or not. The "g" key, by default, is the shortcut to repeat the last executed command.
-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.
-disabledImage(-di)	string
Image used when the button is disabled. Image size must be the same as the image specified with the i/image flag. This is a Windows only flag.
-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
Command executed when the control is double clicked.
-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
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.
-enableBackground(-ebg)	boolean
Enables the background color of the control.
-enableCommandRepeat(-ecr)	boolean
This flag only affects menu items to which a command can be attached. Specify true and the command may be repeated by executing the command repeatLast. This flag is true by default for all items except for option box items.
-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).
-exists(-ex)
Returns whether the specified object exists or not. Other flags are ignored.
-flat(-fla)	boolean
Sets whether the control will be a flat button (0 false, 1 true).
-flexibleWidthType(-fwt)	int
This flag is used to have the shelf button have a wider or thinner width. The valid values are: Standard = 1, Custom = 2, Automatic = 3. The Standard type will resize, keeping the aspect ratio, to 32x32 pixels. The Automatic type will adjust the button width to make sure wide images are used properly. The Custom type will allow the user to choose the desired width for the icon. Default value is 3.
-flexibleWidthValue(-fwv)	int
This flag is only useful when the Custom flexibleWidthType is chosen. The value is a width in pixels.
-flipX(-fx)	boolean
Is the image flipped horizontally?
-flipY(-fy)	boolean
Is the image flipped vertically?
-font(-fn)	string
The font for the text. Valid values are "boldLabelFont", "smallBoldLabelFont", "tinyBoldLabelFont", "plainLabelFont", "smallPlainLabelFont", "obliqueLabelFont", "smallObliqueLabelFont", "fixedWidthFont" and "smallFixedWidthFont".
-fullPathName(-fpn)
Return the full path name of the widget, which includes all the parents.
-handleNodeDropCallback(-hnd)	script
Specify a script callback which is called when a node is dropped on the control. The name of the node being dropped will be passed to the function (python callable) or appended to the end (script) to form the command to be executed.
-height(-h)	int
The height of the control. The control will attempt to be this size if it is not overruled by parent layout conditions.
-highlightColor(-hlc)	float float float
The highlight 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.
-highlightImage(-hi)	string
Highlight image displayed while the cursor is over the control. Image size must be the same as the image specified with the -i/image flag. This is a Windows only flag.
-image(-i)	string
If you are not providing images with different sizes then you may use this flag for the control's image. If the "iconOnly" style is set, the icon will be scaled to the size of the control.
-image1(-i1)	string
First of three possible icons. The icon that best fits the current size of the control will be displayed.
-image2(-i2)	string
Second of three possible icons. The icon that best fits the current size of the control will be displayed.
-image3(-i3)	string
Third of three possible icons. The icon that best fits the current size of the control will be displayed.
-imageOverlayLabel(-iol)	string
A short string, up to 6 characters, representing a label that will be displayed on top of the image.
-isObscured(-io)
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.
-label(-l)	string
The text that appears in the control.
-labelEditingCallback(-lec)	script
Specify a callback which is called after the user double clicks the label of the control to give it a new label. The new label string will be passed to the callback.
-labelOffset(-lo)	int
The label offset. Default is 0. Currently only available when -st/style is set to "iconAndTextCentered".
-manage(-m)	boolean
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.
-marginHeight(-mh)	uint
The number of pixels above and below the control content. The default value is 1 pixel.
-marginWidth(-mw)	uint
The number of pixels on either side of the control content. The default value is 1 pixel.
-menuItem(-mi)	string string
Creates menu items for this button by passing in arguments for the menu item label and command for each item. These should be passed as strings: "label" "command" for each use of this flag in the command.
-menuItemPython(-mip)	int
This flag is used to specify that a menu item is in Python. The integer value is the index of the menuItem that is modified by this flag. This is 0 based, so it corresponds to the (index+1)th occurrence of the /-mi/-menuItem flag.
-menuItemWithOptionBox(-mio) 2023	string string string
Creates menu items that include an option box. Arguments passed to the flag are "label" "comand" "option box command";
-noBackground(-nbg)	boolean

-noDefaultPopup(-ndp)
Disable the default popup menus.
-numberOfPopupMenus(-npm)
Return the number of popup menus attached to this control.
-overlayLabelBackColor(-olb)	float float float float
The RGBA color of the shadow behind the label defined by imageOverlayLabel. Default is 50% transparent black: 0 0 0 .5
-overlayLabelColor(-olc)	float float float

-scaleIcon(-sic)
For "textOnly" and "iconOnly" style, this flag has no effect. For other styles, if the flag is specified, the icon will be scaled to the size of the control.
-selectionImage(-si)	string
Image displayed while the control is selected. Image size must be the same as the image specified with the -i/image flag. This is a Windows only flag.
-sourceType(-stp)	string
Sets the language type for the command script. Can only be used in conjunction with the c/command or dcc/doubleClickCommand flags. Valid values are "mel" (enabled by default), and "python".
-statusBarMessage(-sbm)	string
Extra string to display in the status bar when the mouse is over the control.
-style(-st)	string
The draw style of the control. Valid styles are "iconOnly", "textOnly", "iconAndTextHorizontal", "iconAndTextVertical", and "iconAndTextCentered". (Note: "iconAndTextCentered" is only available on Windows). If the "iconOnly" style is set, the icon will be scaled to the size of the control.
-useAlpha(-ua)	boolean
Is the image using alpha channel?
-useTemplate(-ut)	string
Forces the command to use a command template other than the current one.
-version(-ver)	string
