Olá Manuel, First save the style (using the GUI or using PyQGIS) as a qml file.
To apply the style to another layer (use the Python console to test the code): 1) Select the other layer you want to apply the style 2) Run the PyQGIS code: l = iface.activeLayer() l.loadNamedStyle('/home/manuel/awesome.qml') l.triggerRepaint() Good luck!
