The CloseWindow command element closes a window in a running Maplet application.

A window is a Maplet application element. A window should not be thought of as a Maplet application, but rather as one element within a Maplet application. A Maplet application can contain more than one window. Each window can contain many elements that control the layout and function of the window.

A CloseWindow element cannot contain other elements.

A CloseWindow element can be contained in a Maplet element; in an equation for the onapprove, oncancel, onchange, onclick, ondecline, or onstartup option for an element; or wrapped in an Action element as a parameter in an element that accepts an onchange or onclick option without an equation.

The following table describes the control and use of the CloseWindow element options.

An x in the I column indicates that the option can be initialized, that is, specified in the calling sequence (element definition).

An x in the R column indicates that the option is required in the calling sequence.

An x in the G column indicates that the option can be read, that is, retrieved by using the Get tool.

An x in the S column indicates that the option can be written, that is, set by using the SetOption element or the Set tool.

The opts argument can contain one or more of the following equations that set Maplet application options.

window = reference to Window element (name or string)

The reference to the window to be closed.

Note: In the Standard Worksheet, RunWindow displays a window and sets its parent to be the window that is currently running and enabled. If there are no other windows running, then the window does not have a parent. CloseWindow closes a window and also closes its child windows. In the Command-line interface, RunWindow displays a window, but it does not set a parent.  CloseWindow closes a window. For more information, see compatibility.
