List Box Directory Reader

List Box Directory Reader
This example uses a list box to display the files in a directory. When the user
double clicks on a list item, one of the following happens:
• If the item is a file, the GUI opens the file appropriately for the file type.
• If the item is a directory, the GUI reads the contents of that directory into
the list box.
• If the item is a single dot (
.), the GUI updates the display of the current
directory.
• If the item is two dots (..), the GUI changes to the directory up one level and
populates the list box with the contents of that directory.
The following figure illustrates the GUI.
