Constructor contents

To keep the GUI up-to-date with the application state and vice versa, you use keywords as targets of widgets. Keywords are defined as members of a form, and the form is passed to the dialog box as a dialog box constructor argument. For more information, see AFXKeywords. The following script shows how you can use keywords to construct a dialog box. Figure 1 shows the Graphics Options dialog box generated by the example script.
