Hi, I'm developing a plug-in in which I would like to edit the symbol levels for controlling rendering order of the vector layer symbology. With this code I can switch the symbol levels feature on and off, and the GUI confirms it: >>> renderer = qgis.utils.iface.activeLayer().rendererV2() >>> renderer.setUsingSymbolLevels(True) >>> renderer.usingSymbolLevels() True >>> renderer.setUsingSymbolLevels(False) >>> renderer.usingSymbolLevels() False However, I haven't figured out how to set the value of the individual levels... The QgsFeatureRendererV2 class doesn't seem to have appropriate methods. There's also this class: QgsSymbolV2LevelItem (QgsSymbolV2 *symbol, int layer) But I'm not sure if it relates to the above levels or to symbol layers (something different). Any help greatly appreciated. Thanks, Jorge ________________________________________ Jorge Gil Research Associate Bartlett School of Graduate Studies
