gridLayout(*args, **kwargs)

This layout arranges children in a grid fashion where every cell in the grid is the same size. You may specify the number of rows and columns as well as the width and height of the grid cells.

Flags:

Long name (short name)		Argument Types	Properties
allowEmptyCells (aec)		bool
	Specify true if you want free positioning of the children in the layout and potentially leaving empty cells between children. Set to false if you want the children to always be packed together. The default is true.
annotation (ann)		unicode
	Annotate the control with an extra string value.
autoGrow (ag)		bool
	Specify true if you want the grid layout size to grow as children are added. For example, if the grid layout has 2 columns and 2 rows then adding a fifth child will cause the grid to expand to 3 rows if this flag is true, otherwise the grid will remain the same size and the new child will be hidden from view until you expand the size of the grid using the appropriate flags. The default is true.
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.
cellHeight (ch)		int
	A positive non-zero integer value indicating the height of cells in the grid layout.
cellWidth (cw)		int
	A positive non-zero integer value indicating the width of cells in the grid layout.
cellWidthHeight (cwh)		int, int
	Two positive non-zero integer values for indicating the width and height, respectively, of the cells in the grid layout.
childArray (ca)		bool
	Returns a string array of the names of the layout’s immediate children.
columnsResizable (cr)		bool
	Specify true if you want the number of columns to adjust according to the width of the layout. Set to false if you want the number of columns to remain fixed when the width of the layout is changed. The default is false.
defineTemplate (dt)		unicode
	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.
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 “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)		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 true|false depending upon whether the specified object exists. Other flags are ignored.
fullPathName (fpn)		unicode
	Return the full path name of the widget, which includes all the parents
gridOrder (go)		bool
	As opposed to the childArray flag, the gridOrder flag returns the children of the grid Layout in the order they are diplayed in the window.
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.
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.
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.
numberOfColumns (nc)		int
	A positive non-zero integer value indicating the number of columns in the grid layout.
numberOfPopupMenus (npm)		bool
	Return the number of popup menus attached to this control.
numberOfRows (nr)		int
	A positive non-zero integer value indicating the number of rows in the grid layout.
numberOfRowsColumns (nrc)		int, int
	Two positive non-zero integer values for the number of rows and columns, respectively, in the grid layout.
parent (p)		unicode
	The parent layout for this control.
popupMenuArray (pma)		bool
	Return the names of all the popup menus attached to this control.
position (pos)		unicode, int
	Specify the name of a child control in the grid layout along with a 1-based integer value indicating the desired position of the child. Positions increase from left to right within a row and then wrap around to the next row increasing from top to bottom. For example, a grid layout with 3 columns and 2 rows has 6 visible positions where 1, 2 and 3 occupy the first row and 4, 5 and 6 occupy the second.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
preventOverride (po)		bool
	If true, this flag disallows overriding the control’s attribute via the control’s right mouse button menu.
useTemplate (ut)		unicode
	Force 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.
