Exercise 6-1. Working with Files

This exercise is meant to take what you have learned about file manipulation in Chapter 6 and integrate it with the widgets from previous chapters. The user interface for this exercise should include three widgets: GtkEntry, GtkFileChooserButton, and GtkButton.

The GtkEntry widget will allow the user to enter a single line of text that will be saved in a file on the system. The location of the file is chosen in the GtkFileChooserButton widget with an action of GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER. Lastly, the GtkButton widget will initiate the saving of the file when it is clicked. In the downloadable exercise solution, the text will be saved to a file named arbitrary_file at the selected location when the user clicks the button.
