[PyQt] Fwd: QStandardItem check state

[Jamie Riotto]

He,
Hopefully this helps:

from PyQt4.QtCore import *
from PyQt4.QtGui import *

import sys
from random import randint

class view(QListView):

   def __init__(self, parent=None):
       super(view, self).__init__(parent)

       model = QStandardItemModel()

       for n in range(10):
           item = QStandardItem('Item %s' % randint(1, 100))
           check = Qt.Checked if randint(0, 1) == 1 else Qt.Unchecked

           item.setCheckState(check)
           item.setCheckable(True)

           model.appendRow(item)

       self.setModel(model)
       self.show()

       model.itemChanged.connect(self.on_itemChanged)


   @pyqtSlot(QStandardItem)
   def on_itemChanged(self,  item):
       state = ['UNCHECKED', 'TRISTATE',  'CHECKED'][item.checkState()]
       print "Item with text '%s', is at state %s\n" % ( item.text(),  state)


if __name__ == '__main__':
   app = QApplication(sys.argv)
   widget = view()
   widget.show()


--------------------------------------------------------------
