An example of using the TixFileSelectDialog widget is in figure 5-1
. At line 1, we create a TixFileSelectDialog widget and set
  the title of the dialog to ``Select A File'' using the 
-title  option. We also use the 
-command option to specify that the
  procedure 
selectCmd should be called when the user has selected a
  file. 
selectCmd will be called with one parameter, the filename
  selected by the user. When the TixFileSelectDialog widget is created, it
  is initially not shown on the screen. Therefore, at line 3, we call its
  
popup widget command to place the widget on the screen.
 tixFileSelectDialog .file -title "Select A File" -command selectCmd.file subwidget fsbox config -pattern "*.txt" -directory /usr/info
.file popup
proc selectCmd {filename} {
    puts "You have selected $filename"
}
