Ok, I tried to help out here by creating a trivial example, but I seem
to have a problem of my own! Here is the example:
==================================================
from PyQt4 import QtCore, QtGui
class MainWindow(QtGui.QMainWindow):
def __init__(self):
super(MainWindow, self).__init__()
self.textEdit1 = QtGui.QPlainTextEdit()
self.textEdit1.setPlainText("Text Editor #1")
self.textEdit2 = QtGui.QPlainTextEdit()
self.textEdit2.setPlainText("Text Editor #2")
self.setCentralWidget(self.textEdit1)
self.createActions()
self.createToolBars()
def createActions(self):
self.edit1Act = QtGui.QAction(QtGui.QIcon(), "&Editor-1",
self, shortcut=QtGui.QKeySequence.New,
statusTip="", triggered=self.centralizeEdit1)
self.edit2Act = QtGui.QAction(QtGui.QIcon(),"&Editor-2",
self, shortcut=QtGui.QKeySequence.Open,
statusTip="", triggered=self.centralizeEdit2)
def createToolBars(self):
self.fileToolBar = self.addToolBar("Central Widget Control")
self.fileToolBar.addAction(self.edit1Act)
self.fileToolBar.addAction(self.edit2Act)
def centralizeEdit1(self):
self.setCentralWidget(self.textEdit1)
def centralizeEdit2(self):
self.setCentralWidget(self.textEdit2)
if __name__ == '__main__':
import sys
app = QtGui.QApplication(sys.argv)
mainWin = MainWindow()
mainWin.show()
sys.exit(app.exec_())
================================================
When I run this, it correctly sets Text Edit #1 as Central Widget.
Pressing "Editor-2" button correctly changes the Central
Widget to Text Edit #2, however, when I press "Editor-1" button to
restore Text Edit #1 to Central Widget I get:
RuntimeError
"underliying C/C++ object has been deleted"
Any clues as to what I'm doing wrong??? Thanks - jamie
