ColorHighlighter on JXTreeTable - Change selection

2019-02-25 21:50发布

I'm using an JXTreeTable with several ColorHighlighters to change the background color of the rows that include a specific value.

If a row is selected, the color will change to SelectionBackground.

Is it possible to change the selection background color based on the predicates or color highlighters without an complete new renderer?

EDIT: If a row is selected and has an highlighting, ther should be another background color as on a row where is no highlighting.
