phoenix_title wx.dataview.DataViewValueAdjuster

This class can be used with 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 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 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())

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

New in version 4.1/wxWidgets-3.1.1.
