pymel.core.windows.menuBarLayout¶
Create a layout containing a menu bar. The menu bar will appear and behave similar to any menu bar created with the ‘window -menuBar true’ command. Menus may be created with a menuBarLayout as their parent. Child controls are simply positioned to fill the menuBarLayout area beneath the menu bar consequently, some other layout should be used as the immediate child.
Flags:
Long Name / Short Name Argument Types Properties annotation / ann unicode 
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. childArray / ca bool
Returns a string array of the names of the layout’s immediate children. defineTemplate / dt unicode
Puts the 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. 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. 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. 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. menuArray / ma bool
Return a string array containing the names of the menus in the layout’s menu bar. menuBarVisible / mbv bool
Visibility of the menu bar. menuIndex / mi unicode, int
Sets the index of a specified menu. 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. numberOfChildren / nch bool
Returns in an int the number of immediate children of the layout. numberOfMenus / nm bool
Return the number of menus attached to the layout’s menu bar. 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. useTemplate / ut unicode
Forces the command to use a command template other than the current one. 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. Derived from mel command maya.cmds.menuBarLayout
