尽管具有默认的“与”谓词，但ViewerFilter上还是一个“或”谓词？

Question

I am developing a RCP application which contains a TreeViewer and I want to activate multiple filters on it that should work with the "OR" predicates, for example :

A
|--B
|--|--redColor
|--|--blueColor
|--C
|--|--greenColor

I have a filter to show the redColor and a filter to show the greenColor . but when activating these two filters together, nothing is displayed.

My filter class extends the ViewerFilter class

您必须制作一个内部具有“或”条件的ViewerFilter，而不是两个单独的过滤器。
