file.  It implements the GtkFileChooser interface.  Visually, it is a
file name with a button to bring up a GtkFileChooserDialog.
The user can then use that dialog to change the file associated with
that button.  This widget does not support setting the "select-multiple"
property to TRUE. Create a button to let the user select a file in /etc
# Create a button to let the user select a file in /etc
button <- gtkFileChooserButton("Select a file", "open")
button$setCurrentFolder("/etc")
  
The GtkFileChooserButton supports the GtkFileChooserActions GTK_FILE_CHOOSER_ACTION_OPEN and GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
  PLEASE NOTE: The GtkFileChooserButton will ellipsize the label,
and thus will thus request little horizontal space.  To give the button
more space, you should call gtkWidgetSizeRequest,
gtkFileChooserButtonSetWidthChars, or pack the button in
such a way that other interface elements give space to the widget.gtkFileChooserButton is the result of collapsing the constructors of GtkFileChooserButton (gtkFileChooserButtonNew, gtkFileChooserButtonNewWithBackend) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.dialog [GtkFileChooser : *       : Write / Construct Only]GtkFileChooserDialog associated with the button.
