Starting the User Interface Editor

To start the user interface editor for variable user interfaces (vui):

Select a window in the experiment that contains a variable user interface.
In the Components menu, point to VUI window, and then select UI Developer Mode.
The user interface editor window opens in a reduced view consisting of a menu bar and a toolbar. The window title displays the variable user interface to which the window refers.
Edit the variable user interface.
To finish editing, open the File menu of the user interface editor and select Exit UI Developer mode.
If you have not saved changes in the variable user interface, a message appears. You can save or discard your changes, or cancel the action.
If you continue, the user interface window is closed.
