Hello All,
First off I'm quite the newbie when it comes to developing PyQGIS plugins so hopefully this post makes sense... I'm creating a vector layer using the memory provider. Layer consists of polygons and everything is working great. I'm now attempting to tailor the appearance of the symbols. Following the advice in this post (http://lists.osgeo.org/pipermail/qgis-developer/2011-April/013772.html) I successfully created just an outline (i.e. no fill): props = { 'color_border' : '255,0,0,255', 'style' : 'no', 'style_border' : 'solid' } s = QgsFillSymbolV2.createSimple(props) vl.setRendererV2( QgsSingleSymbolRendererV2( s ) ) This is close to what I'd like but I notice that when selecting features the selected features become filled which is not what I'd like. Manually adjusting the properties via the "Symbol properties" dialog I discovered that by selecting "Outline: Simple line" from the "Symbol layer type" pulldown provides the functionality I desire. When selecting features the color of the outline changes while remaining un-filled. Looking at the resulting entry in symbology-ng-style.xml shows the following: <symbol outputUnit="MM" alpha="1" type="fill" name="Dash Foo"> <layer pass="0" class="SimpleLine" locked="0"> <prop k="capstyle" v="square"/> <prop k="color" v="0,85,0,255"/> <prop k="customdash" v="5;2"/> <prop k="joinstyle" v="bevel"/> <prop k="offset" v="0"/> <prop k="penstyle" v="dash"/> <prop k="use_custom_dash" v="0"/> <prop k="width" v="0.37"/> </layer> </symbol> I haven't had any luck in figuring out how to get the proper combination of type="fill" while using "SimpleLine". I also noticed that if I follow the example in the PyQGIS Cookbook to display the complete list of types for a QgsSymbolV2.Fill none of the "Outline: <foo>" types from the dialog pulldown are listed: myRegistry = QgsSymbolLayerV2Registry.instance() for item in myRegistry.symbolLayersForType(QgsSymbolV2.Fill): ... print item CentroidFill LinePatternFill PointPatternFill SVGFill SimpleFill Any advice on how to replicate the "Outline: Simple line" symbology will be greatly appreciated! Thanks, -- Dan
