Hi,
I am trying to create a multicolumn TreeBox where I want to change the background color to some of the cells. After creating the the TreeBoxNode I invoke the method setBackgroundColor but it seems to do nothing.
If I query the color of the background before changing it, it returns the value 0xFF000000 (when it should be 0xFFFFFFFF). After changing the background color backgroundColor() returns the value that I set, but the cell it is still drawn using a white background.
