An Integrated Development Environment with Visualizations for Improving Software Comprehensibility

jGRASP Accessibility

Current and Future WCAG Compliance

jGRASP 2.1.0 Beta 9 and higher is fully WCAG 2.1 Level AA compliant, based on our automated testing and to the best of our knowledge. A final release should be available by the end of May.

We will continue to improve accessibility, in ways specified by the WCAG and in other ways.

Notable Accessiblity Features

If you find a problem with any accessibility features of jGRASP or with the content of the jgrasp.org website, please let us know.

UI Scaling

The entire interface - fonts, icons, and much of the spacing - is globally scalable. The global scale can be accessed through "Settings" > "Font", through the key combinations Ctrl/Cmd-plus, Ctrl/Cmd-minus, Ctrl/Cmd-zero, or by holding down Ctrl or Cmd and Shift while scrolling the mouse wheel.

Individual editing, message, and many visualization windows can be scaled separately using "Settings" > "CSD Window Settings" > "Workspace", "Project", or "File" > "Font" or "Font Size", through the key combinations Ctrl/Cmd-Shift-plus, Ctrl/Cmd-Shift-minus, Ctrl/Cmd-Shift-zero, or by holding down Ctrl or Cmd and while scrolling the mouse wheel.

Toolbar icons can be scaled separately using "View" > "Toolbar Icon Size".

Colors and Contrast

The Look&Feel can be selected through "Settings" > "Look And Feel / Theme". A high contrast dark theme and dark themes with enhanced focus visibility are available. This and editing window colors can be set using "Settings" > "Colors". The themes with enhanced focus visibility correct a problem with the Java Metal L&F, where for some UI element types no focus indication is shown unless a sub-element is selected.

Assistive Technologies

The ui of the jGRASP IDE is implemented mainly in Java Swing. The Swing ui components implement appropriate parts of the Java Accessibility API. As of jGRASP version 2.1.0 Beta 9, all custom components and visualizations also implement relevant portions of this API.

On Windows, assistive technologies communicate with the Java Accessibility API through the Java Access Bridge, which is included with Java but not enabled by default. Numerous screen readers and other assistive technology tools support the Java Access Bridge.

On macOS, Java Accessibility API communication access is built-in. The VoiceOver screen reader included with macOS and other macOS compatible screen readers work with jGRASP.

On Linux, Java Accessibility API communication access is built-in to most popular desktop environments, and accessibility tools are included with most distributions.

Other Accessibility Settings

jGRASP 2.1.0 uses F6 and Shift-F6 for block keyboard navigation. This will cycle through main sections of the UI, and enables faster keyboard navigation than Tab navigation alone.

In jGRASP 2.1.0, turning on "Settings" > "Desktop" > "Navigation Information Label" will enable a message bar that shows important keyboard navigation key combinations for the component that has keyboard focus. If you are a keyboard-only user or heavily use keyboard navigation, we suggest turning this on until you are familiar with the keyboard navigation.

In jGRASP 2.1.0, turning on "Settings" > "Desktop" > "Focus Indicator Popup" will cause a small popup to display briefly at the location of the component with keyboard focus, whenever keyboard focus changes. This can help to identify the focused component, especially if you are using a Look&Feel with subtle focus indications.

Tooltips can be made persistent using "Settings" > "Desktop" > "Persistent Tooltips".

Flashing cursors can be turned off globally using "Settings" > "Desktop" > "Blinking Cursors".
