pymel.core.windows.scriptedPanel¶

scriptedPanel(*args, **kwargs)¶

This command will create an instance of the specified scriptedPanelType. A panel is a collection of UI objects (buttons, fields, graphical views) that are grouped together. A panel can be moved around as a group within the application interface, and torn off to exist in its own window. The panel takes care of maintaining the state of its UI when it is relocated, or recreated. A scripted panel is a panel that is defined in MEL, with all of the required callbacks available as MEL proc’s.

Flags:

Long Name / Short Name		Argument Types	Properties
control / ctl		bool
	Returns the top level control for this panel. Usually used for getting a parent to attach popup menus. CAUTION: panels may not have controls at times. This flag can return if no control is present.
copy / cp		unicode
	Makes this panel a copy of the specified panel. Both panels must be of the same type.
createString / cs		bool
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
	Attaches a tag to the Maya panel.
editString / es		bool
exists / ex		bool
	Returns whether the specified object exists or not. Other flags are ignored.
init / init		bool
	Initializes the panel’s default state. This is usually done automatically on file -new and file -open.
isUnique / iu		bool
	Returns true if only one instance of this panel type is allowed.
label / l		unicode
	Specifies the user readable label for the panel.
menuBarVisible / mbv		bool
	Controls whether the menu bar for the panel is displayed.
needsInit / ni		bool
	(Internal) On Edit will mark the panel as requiring initialization. Query will return whether the panel is marked for initialization. Used during file -new and file -open.
parent / p		unicode
	Specifies the parent layout for this panel.
popupMenuProcedure / pmp		script
	Specifies the procedure called for building the panel’s popup menu(s). The default value is buildPanelPopupMenu. The procedure should take one string argument which is the panel’s name.
replacePanel / rp		unicode
	Will replace the specified panel with this panel. If the target panel is within the same layout it will perform a swap.
tearOff / to		bool
	Will tear off this panel into a separate window with a paneLayout as the parent of the panel. When queried this flag will return if the panel has been torn off into its own window.
tearOffCopy / toc		unicode
	Will create this panel as a torn of copy of the specified source panel.
type / typ		unicode
	This flag specifies the type of scripted panel to create.
unParent / up		bool
	Specifies that the panel should be removed from its layout. This (obviously) cannot be used with query.
useTemplate / ut		unicode
	Force the command to use a command template other than the current one. Flag can have multiple arguments, passed either as a tuple or a list.
