About the List Box Directory Example
This example uses a list box to display the files in a folder. When the user
double clicks a list item, one of the following happens:
• Iftheitemisafile,theGUIopensthefileappropriatelyforthefiletype.
• If the item is a folder, the GUI reads the contents of that folder into the
list box.
• If the item is a single dot (.), the GUI updates the display of the current
folder.
• If the item is two dots (..), the GUI changes to the parent folder (one level
up) and populates the list box with the contents of that folder.
The following figure illustrates the GUI.
