So I have a QTableWidget which I want to have a context menu on. The context menu actions slots need to work differently depending on where I click the context menu at. So initially I was using the currentIndex method to get the appropriately selected cell. However I want to react differently if the context menu is brought up in the empty space around my cells. So then I moved to using rowAt and columnAt along with the QCursor.pos() that the context menu appeared at. The problem is the values from these two methods disagree. It seems like somehow the rowAt and columnAt are using the bottom right hand side of the cursor to map there position instead of the top left. The code below demonstrates my problem. If you right click and select current position from the menu it should print out two indices one from each method. What am I doing wrong?


Qt Code: 
  1. from PyQt4 import QtGui, QtCore
  2. import sys
  3.  
  4.  
  5. class Test(QtGui.QTableWidget):
  6.     def __init__(self):
  7.         super(Test, self).__init__(5,5)
  8.         self.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
  9.         self.customContextMenuRequested.connect(self.ctxMenu)
  10.  
  11.     def ctxMenu(self):
  12.         menu = QtGui.QMenu(self)        
  13.         a = QtGui.QAction("Current Cell", self)
  14.         menu.addAction(a)
  15.         a.triggered.connect(self.contextCurPos)
  16.         self.cursor_zero = QtGui.QCursor.pos()
  17.         menu.exec_(QtGui.QCursor.pos())
  18.  
  19.     def contextCurPos(self):
  20.         pos = self.mapFromGlobal(self.cursor_zero)
  21.         col = self.columnAt(pos.x())
  22.         row = self.rowAt(pos.y())
  23.         print('Map From Cursor    %d, %d' % (row, col))
  24.         model_idx = self.model().createIndex(row, col) 
  25.  
  26.         model_idx = self.currentIndex()
  27.         print('From Current Index %d, %d' % (model_idx.row(), model_idx.column()))
  28.         print('\n')
  29.  
  30. app = QtGui.QApplication(sys.argv)
  31. x = Test()
  32. x.show()
  33. sys.exit(app.exec_())
