Visual Disabilities

Follow these guidelines to make your application more accessible to people with visual disabilities:

• Do not hardcode application colors.

• Do not hardcode graphic attributes such as line, border, and shadow thickness. These attributes should scale with font size.

• Do not hardcode font sizes and styles.

• Provide descriptive names for all widgets. In particular, include descriptive names in your application code for widgets that do not display labels on the screen; for example, palette items or icons. This often enables screen-reading software to provide descriptive information to blind users.
