pymel.core.windows.optionMenuGrp¶

optionMenuGrp(*args, **kwargs)¶

All of the group commands position their individual controls in columns starting at column 1. The layout of each control (ie. column) can be customized using the -cw/columnWidth, -co/columnOffset, -cat/columnAttach, -cal/columnAlign, and -adj/adjustableColumnflags. By default, columns are left aligned with no offset and are 100 pixels wide. Only one column in any group can be adjustable. This command creates a pre-packaged collection of label text, option menu and an extra label. Both the label and extra label are optional. Subsequent calls to the menuItem command will place them in the option menu. When adding menu items to the option menu after the initialization step, use the name of the options menu itself. See the example below for more details. Note that commands attached to menu items will not get called. Use the -cc/changedCommandflag to be notified when the user changes the value of the option menu.

Modifications:

• returns an empty list when the result is None for flags: (query and (itemListLong or itemListShort))

docTag / dtg		unicode
	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 dragControlvalue 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 dragControlvalue 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		bool
	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		bool
	Enables the background color of the control.
exists / ex		bool
	Returns whether the specified object exists or not. Other flags are ignored.
extraLabel / el		unicode
	If present on creation this specifies that there will be an extra label to the right of the option menu. Sets the string to be the extra label text.
fullPathName / fpn		bool
	Return the full path name of the widget, which includes all the parents
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.
isObscured / io		bool
	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.
itemListLong / ill		bool
	Returns the long names of the items.
itemListShort / ils		bool
	Returns the short names of the items.
label / l		unicode
	If present on creation this specifies that there will be a label to the left of the option menu. Sets the string to be the label text.
manage / m		bool
	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.
noBackground / nbg		bool
	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.
numberOfItems / ni		bool
	Returns the number of items.
numberOfPopupMenus / npm		bool
	Return the number of popup menus attached to this control.
parent / p		unicode
	The parent layout for this control.
popupMenuArray / pma		bool
	Return the names of all the popup menus attached to this control.
preventOverride / po		bool
	If true, this flag disallows overriding the control’s attribute via the control’s right mouse button menu.
rowAttach / rat		int, unicode, int
	Arguments are : column, attachment type, offset. Possible attachments are: top | bottom | both. Specifies attachment types and offsets for the entire row.
select / sl		int
	Selects an item by index. The first item is 1.
useTemplate / ut		unicode
	Force the command to use a command template other than the current one.
value / v		unicode
	Select an item by value. Also, returns the text of the currently selected item.
visible / vis		bool
	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.
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. Flag can have multiple arguments, passed either as a tuple or a list.
