Unview - Function Summary

Summary:

Closes window views, except main view.

Usage:

unview

Refinements:

/all - Close all views, including main view

/only - The only refinement.

face - Close a single view (must be: object)

Description:

The UNVIEW function is used to close a window previously opened with the VIEW function. By default, the last window that has been opened will be closed. To close a specific window, use the /only refinement and specify the window's face (that which was returned from a layout, for example). All windows can be closed with the /all refinement.

The example below opens a window that displays a Close button. Clicking on the button will evaluate the UNVIEW function and the window will be closed.

view layout [button "Close" [unview]]

Note that the VIEW function will not return until all windows have been closed. (Use VIEW/new to return immediately after the window is opened.)

The next example will open two windows, then use UNVIEW/only to close each one separately.

out1: layout [button "Close 2" [unview out2]] out2: layout [button "Close 1" [unview out1]] view/new out1 view/new out2 do-events

You could have closed both windows with the line:

unview/all
