The GetFile(opts) calling sequence displays a file dialog that allows the user to choose a file.  The value returned is the string corresponding to the chosen file.  If a file is not selected, an exception is raised.

The GetFile sample Maplet worksheet describes how to write a Maplet application that behaves similarly to this routine by using the Maplets[Elements] package.

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

approvecaption = string or symbol

The text that appears on the button that is clicked to select the file. By default, the value is Open.

filefilter = string or symbol

The extension of the files that display.  By default, the value is "*", that is, all files are shown. It can also be used with other extensions, for example, "mws", "m", or "mpl".

filterdescription = string or symbol

A description of the filefilter. By default, the value is the value of the option filefilter.

title = string or symbol

Specifies the Maplet application title.  By default, the title is Get File.
