|phoenix_title| **wx.dataview.DataViewValueAdjuster**
==========================================================================================================================================
This class can be used with :meth:`wx.dataview.DataViewRenderer.SetValueAdjuster` to customize rendering of model values with standard renderers.
Can be used to change the value if it is shown on a highlighted row (i.e. in selection) which typically has dark background. It is useful in combination with :ref:`wx.dataview.DataViewTextRenderer` with markup and can be used e.g. to remove background color attributes inside selection, as a lightweight alternative to implementing an entire :ref:`wx.dataview.DataViewCustomRenderer` specialization.

# Markup renderer that removes bgcolor attributes when in selection
class DataViewMarkupRenderer(wx.dataview.DataViewTextRenderer):
def __init__(self):
super(DataViewMarkupRenderer, self).__init__()
self.EnableMarkup()
self.SetValueAdjuster(DataViewMarkupRenderer._Adjuster())

def MakeHighlighted(self, value):
pos = value.find(" bgcolor=\"")
if pos != -1:
pos2 = s.find('"', pos + 10)
value = value[:pos] + value[pos2+1:]
