I have a vector layer with a "Simple Marker" for the style. I see I can create Data Defined properties for both the colour and the outline colours.
In Python, I'm able to change the marker's base colour (for the data defined property), but I can't seem to find how to change the outline's colour.
Here's what I have:
symbols = layer.rendererV2().symbols() symbol = symbols expr = 'color_rgba(255,0,0,0)' symbol.symbolLayer(0).setDataDefinedProperty('color', expr) # I would expect this to work, but it doesn't symbol.symbolLayer(0).setDataDefinedProperty('outlineColor', expr)
