Synopsis

optionMenu [-annotation string] [-backgroundColor float float float] [-changeCommand script] [-defineTemplate string] [-docTag string] [-dragCallback script] [-dropCallback script] [-enable boolean] [-enableBackground boolean] [-exists] [-fullPathName string] [-height int] [-isObscured] [-itemListLong] [-itemListShort] [-label string] [-manage boolean] [-numberOfItems] [-numberOfPopupMenus] [-parent string] [-popupMenuArray] [-preventOverride boolean] [-select int] [-useTemplate string] [-value string] [-visible boolean] [-visibleChangeCommand script] [-width int] [string]

optionMenu is undoable, queryable, and editable.

Return value

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

Flags

Long name (short name)	Argument types	Properties
-exists(-ex)
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.
-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.
-visible(-vis)	boolean
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).
-visibleChangeCommand(-vcc)	script
Command that gets executed when visible state of the control changes.
-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.
-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.
-numberOfPopupMenus(-npm)
Return the number of popup menus attached to this control.
-popupMenuArray(-pma)
Return the names of all the popup menus attached to this control.
-preventOverride(-po)	boolean
If true, this flag disallows overriding the control's attribute via the control's right mouse button menu.
-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.
-enableBackground(-ebg)	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'")
-fullPathName(-fpn)	string
Return the full path name of the widget, which includes all the parents
-changeCommand(-cc)	script
Adds a callback that is called when a new item is selected. The MEL script will have the newly selected item's value substituted for #1. For Python, the callback should be a callable object which accepts one argument, which is the newly selected item's value.
-itemListShort(-ils)
The short names of the menu items.
-itemListLong(-ill)
The long names of the menu items.
-label(-l)	string
The optional label text to the left of the popup menu.
-numberOfItems(-ni)
The number of menu items.
-select(-sl)	int
The current menu item. The argument and return value is 1-based. Note that the current menu item can only be set if it is enabled. -alwaysCallChangeCommand Sets whether the change command is called when the same item is selected in the list. By default, this option is false.
-value(-v)	string
The text of the current menu item.

Flag can appear in Create mode of command	Flag can appear in Edit mode of command
Flag can appear in Query mode of command	Flag can be used more than once in a command.
