Hi Luiz. <br><br>You can get the orderer list of layers from QgsMapCanvas class:<br><br>
<meta name="qrichtext" content="1"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css">
p, li { white-space: pre-wrap; }
</style>
<p style="margin: 0px; text-indent: 0px;"></p><div style="margin-left: 40px;"><i>canvas = qgis.utils.iface.mapCanvas()<br>for i in range( canvas.layerCount() ):</i></div><p style="margin: 0px; text-indent: 0px;"></p><p style="margin: 0px 0px 0px 40px; text-indent: 0px;">
<i> ly = canvas.layer( i ) <br></i></p><p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><i> print <a href="http://ly.name">ly.name</a>(), ly.getLayerID()</i></p><p></p><br>I don't know if there's another method but I guess the QgsLegendInterface class (added in v.1.4) [1] will provide some useful methods to play with legend layers and groups.<br>
<br>Meanwhile (v.1.4) you can get the group names:<br><br>
<meta name="qrichtext" content="1"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><style type="text/css">
p, li { white-space: pre-wrap; }
</style>
<p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><i>legend = qgis.utils.iface.legendInterface()</i></p><p style="margin: 0px; text-indent: 0px;"></p><p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><i>for group in legend.groups():</i></p>
<p style="margin: 0px 0px 0px 40px; text-indent: 0px;"><i> print group</i></p><p></p><br>Germán<br><br>-------------------------<br>[1] <a href="http://doc.qgis.org/head/classQgsLegendInterface.html">http://doc.qgis.org/head/classQgsLegendInterface.html</a><br>

Hi all,<br>
<br>
I am making the python plugin and need show layers in QTreeWidget with same order show in Legend/Layer.<br>
<br>
The list of layers by :<br>
layerRegistry = core.QgsMapLayerRegistry.instance()<br>
it is not same order by Legend.<br>
<br>
I have success get list of layer's name by find the QTreeWidget with name 'Legend':<br>
### getDocWidgetLegend<br>
def getDocWidgetLegend():<br>
widget = None<br>
lst = qgis.utils.iface.mainWindow().children()<br>
for item in lst:<br>
if type(item) == QtGui.QDockWidget and item.objectName().compare('Legend') == 0:<br>
widget = item<br>
return widget<br>
### getMapLegend<br>
def getMapLegend(widgetLegend):<br>
widget = None<br>
for item in widgetLegend.children():<br>
if item.objectName().compare('theMapLegend') == 0:<br>
widget = item<br>
return widget<br>
### Use functions<br>
widgetLegend = getDocWidgetLegend()<br>
treeLegend = getMapLegend(widgetLegend)<br>
### End scripts<br>
<br>
The problem is when the have same layer's name in Legend, i don't know how take exact source.<br>
<br>
The other method is read the entries in project:<br>
project = core.QgsProject.instance()<br>
<br>
I don´t know how get entries in tag Legend in project:<br>
Example QGis project file:<br>
<!DOCTYPE qgis PUBLIC '<a href="http://mrcc.com/qgis.dtd" target="_blank">http://mrcc.com/qgis.dtd</a>' 'SYSTEM'><br>
<qgis projectname="" version="1.5.0-Trunk" ><br>

<legend><br>
<legendlayer open="true" checked="Qt::Checked" name="CB2B-HRC_20091228" ><br>
<filegroup open="true" hidden="false" ><br>
<legendlayerfile isInOverview="0" layerid="CB2B_HRC_2009122820100117201817718" visible="1" /><br>
</filegroup><br>
</legendlayer><br>
....<br>
<br>
I would like how use "project.entryList()" to take values of all layerid's.<br>
<br>
Do someone know how to solve it?<br>
<br>
Thank you Luiz<br>
<br>
