Question

I have the following class in a file named SymbolManager.py:

from qgis.core import *

class SimbolManager:
  def __init__(self):
    self.initSymbols()

  def initSymbols(self):
    self.symbolMap = {}
    props = {'color': '0,0,200'}
    self.symbolMap['SimpleVertex'] = QgsMarkerSymbolV2.createSimple(props)

    props = {'width': '1', 'color': '0,0,255'}
    self.symbolMap['SimpleLine'] = QgsLineSymbolV2.createSimple(props)

  def getSymbolRenderer(self, name):
    symb = self.symbolMap[name]
    if symb is not None:
      return QgsSingleSymbolRendererV2(symb)
    return None

From a file in the same dir I’m trying to import SymbolManager this way:

from PyQt4 import QtCore, QtGui
from Ui_OsmNavigator import Ui_OsmNavigator

from PyQt4.QtCore import *
from PyQt4.QtGui import *
from qgis.core import *

import DbConnection

from SymbolManager import SymbolManager  // HERE IS THE PROBLEM

When I run the script, from inside QGIS it gives me the following error:

line 28, in
from SymbolManager import SymbolManager ImportError: cannot import name SymbolManager

What am I doing wrong?

Answer 1

Because your class isn’t called SymbolManager?

class SimbolManager: 
      ^^^^^^
