hello i have create a layer filter Expression to get specific results query
from my layer and i add this results in list widget using pyqt.
my Expression and my add to list widget work fine(i take correct ids numbers
in the print and i see that ids in list widget).
but if i want to zoom feature using double click signal in list widget then
i take zoom
in the wrong features(features where my Expression is False).Any idea where
i have wrong in my code and to take wrong features zoom?
my code :
__init__
self.connect(self.ui.listWidget, SIGNAL("itemDoubleClicked (QListWidgetItem
*)"), self.Zoomt)
my filter :
def myfilter(self):
layer =
QgsMapLayerRegistry.instance().mapLayersByName("mylayrt")[0]
request = QgsFeatureRequest().setFilterExpression('"name" =
\'{0}\''.format(myname))
for feature in layer.getFeatures(request):
print str(feature.attribute("myid"))
self.ui.listWidget.addItem(str(feature.attribute("myid")))
result print :
1
42
43
44
45
96
111
304
458
508
579
602
606
646
that is ids add correct in list widget (14 ids).
zoom button .
def Zoomt(self):
Vl_Gs =
QgsMapLayerRegistry.instance().mapLayersByName("mylayer")[0]
Vl_Gs.removeSelection
Vl_Gs.setSelectedFeatures([self.ui.listWidget.currentRow()])
self.mapCanvas.zoomToSelected(Vl_Gs)
zoom ids (take first 14 from my layer) :
0
1
2
3
4
5
6
7
8
9
10
11
12
13
14
is len number is correct but the ids zoom is wrong,why?
