    • setBackgroundSelectionColor

      public void setBackgroundSelectionColor(Color newColor)
      Overrides this method to ensure that the new background selection color is not a GColorUIResource. Some Look and Feels will ignore color values that extend UIResource, choosing instead their own custom painting behavior. By not using a UIResource, we prevent the Look and Feel from overriding this renderer's color value.
      Overrides:
      setBackgroundSelectionColor in class DefaultTreeCellRenderer
      Parameters:
      newColor - the new background selection color

    • setBackgroundNonSelectionColor

      public void setBackgroundNonSelectionColor(Color newColor)
      Overrides this method to ensure that the new background non-selection color is not a GColorUIResource. Some Look and Feels will ignore color values that extend UIResource, choosing instead their own custom painting behavior. By not using a UIResource, we prevent the Look and Feel from overriding this renderer's color value.
      Overrides:
      setBackgroundNonSelectionColor in class DefaultTreeCellRenderer
      Parameters:
      newColor - the new background non-selection color

    • fromUiResource

      protected Color fromUiResource(Color color)
      Checks and converts any GColorUIResource to a GColor
      Parameters:
      color - the color to check if it is a UIResource
      Returns:
      either the given color or if it is a GColorUIResource, then a plain GColor instance referring to the same theme color property id.
