I am creating my very first QGIS plugin using two combo boxes - one to select a layer and the other to select a field.
Whilst the layer selection feature seems to work, the field name combo box is not updated when a new layer is selected.
My code is as follows...
self.dlg.comboBox.clear() self.dlg.comboBox_2.clear() layers = self.iface.legendInterface().layers() layer_list =  for layer in layers: layer_list.append(layer.name()) self.dlg.comboBox.addItems(layer_list) selectedLayerIndex = self.dlg.comboBox.currentIndex() selectedLayer = layers[selectedLayerIndex] fields = [field.name() for field in selectedLayer.pendingFields() ] self.dlg.comboBox_2.addItems(fields)
Does anyone happen to know how I can accomplish this?
