There are two file dialog widgets inside Tix: the TixFileSelectDialog (figure 5-2) is similar to the FileSelectionDialog widget in Motif; TixExFileSelectDialog (figure 5-3) looks like its conunterpart in MS Windows. Both widgets let the user navigate through the file system directories and select a file.
One advanced feature of both types of file selection boxes is they use ComboBoxes to store the files, directories and patterns the user has selected in the past. If the user wants to select the same files again, he can simply open the ComboBoxes and click on his past inputs. This saves a lot of keystrokes and is especially useful when the user needs to switch among several files or directories.
