[Qgis-developer] Including style on a Qgis plugin

[Xavier Barnada]

Hi,

Sorry y hadn't been enought specific. The problem was on the images URLs.

I fixed it with this function:

    def fix_qml_rel_urls(self, url):
        """
        Replaces the QML URLs with plugin relative URLs

        :return:
        """

        plugin_dir = os.path.dirname(os.path.realpath(__file__))
        with open(url, 'r') as fd:
            data = fd.read()
        f = etree.fromstring(data)
        for r in f.xpath('//qgis/renderer-v2/symbols/symbol/layer/prop[@k="
name"]'):
            val = r.get('v')
            parent = r.getparent()
            parent.remove(r)
            rel_url = os.path.join(plugin_dir, val)
            r.set('v', rel_url)
            parent.append(r)

        t = etree.tostring(f, pretty_print=True)

        tmp_url = tempfile.NamedTemporaryFile(suffix='.qml', delete=False)

        tmp_url.write(t)
        tmp_url.close()
        return tmp_url.name

I'm sure that this don't work on all the types of symbols but perhaps is
useful for someone
After patch the style I loaded it.

Best reggards.
