From the accessibility guidelines at: http://www.ibm.com/able/guidelines/software/accesssoftware.html section 4.2 says: Use color as an enhancement, not as the only way to convey information or indicate an action. However the Visualiser colours stripes according to the corresponding aspect. An alternative is needed to satisfy the above requirement, such as text labels, or a dithering pattern perhaps. A good way to test this would be to take a project such as the Spacewar example and display it in the Visualiser, then print a screenshot in black and white, and then see if each aspect can be identified.
Implemented in Build 1.3.0.20050805143319 for Eclipse 3.1. Here is how it works: Colours for different types of visualiser stripe are assigned in the usual way, dependant on the colour palette selected in the Visualiser Preferences Drawing Options Tab. If the 'Patterns' option is selected, a Boolean field in the VisualiserPreferences class is set to true and the PatternVisualiserPalette is used. The PatternVisualiserPalette extends the DefaultVisualiserPalette which means that calls to retrieve colour information return results as if the DefaultPalette were selected. This means that returning to view with patterns after viewing with the AJDT Palette for example, will result in the same patterns being used for the same stripes. When stripes are painted, a condition is added as to whether to fill the stripe with colour as usual or have the designated pattern tiled across them. This uses the Boolean field set in the VisualiserPreferences class. This tiling of patterns relies on the PatternVisualiserRenderer. This takes the stripe and the colour associated with the stripe. If the colour is recognised, the allocated pattern from the mapping is used. If the colour is not recognised, the next pattern in the predefined list is used. If all predefined patterns have been used, a random pattern is generated. Once the correct pattern has been determined a call is made to setBackgroundPattern on the stripe. There is currently no Eclipse 3.0 release because SWT only added support for patterns in eclipse 3.1 and so the Pattern class and the fillShapeWithPattern method are missing in 3.0.
