Sorry, here's the original e-mail in plain text:
Hi,
I've discovered some very strange behaviour when trying to
delete a QWidget from a QGridLayout. The following code demonstrates
this behaviour:
from PyQt4 import QtGui
import sys
app = QtGui.QApplication(sys.argv)
grid_layout = QtGui.QGridLayout()
grid_layout.addWidget(QtGui.QWidget())
item = grid_layout.takeAt(0)
item.deleteLater()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'QWidgetItem' object has no attribute 'deleteLater'
This makes no sense to me whatsoever. Firstly, why is it returning
a QWidgetItem when I inserted a QWidget to begin with? Secondly, every
Qt object derives from QObject, and deleteLater() is a method of
QObject, so that method should exist. Additional info:
Python 2.7.6 (default, Mar 22 2014, 22:59:56)
[GCC 4.8.2] on linux2
Not exactly, QLayoutItem or QSpacerItem doesn't inherits of QObject.
As I've sayed in my precedent post, you must use
item.widget().deleteLater().
