Description Diego Gaustein 2012-02-08 11:07:05 EET

Hi. In PySide 1.0.9 I could do

widgets = dict()

class FormLoader(QUiLoader):
  def createWidget(self, className, parent=None, name=""):
  obj = super(FormLoader, self).createWidget(className, parent, name)
  self.widgets[name] = obj
  return obj

and then set properties on the loaded form. Now, using HEAD, I get

Traceback (most recent call last):
  File "...", line 158, in ...
    self.loader.widgets[...].setProperty(...)
RuntimeError: Internal C++ object (PySide.QtGui.QLineEdit) already deleted.

Thanks.

I had to go back to an older version in order to continue development. 1.1.0
also suffers from this bug, while it works alright in 1.0.9.
Cheers.

I believe this bug is duplicate of bug #1060, which is fixed in 1.1.0.

It seems to have reocurred. Someone else reported the same bug #1138, and it
has a patch.

I reported bug #1138 :) It relates to case when you override other than
createWidget() methods (like createLayout() and possible createAction(),
createActionGroup() etc). Can you provide complete example on which bug
reproduces?

Comment 5 Diego Gaustein 2012-02-09 14:14:10 EET

The example in the first comment is pretty much a test case. I build a
dictionary of widgets, and then try to access them: the c++ objects had already
been deleted. I reverted to 1.0.9 and I am no longer having this issue.

Working example

Diego,

I can't reproduce this bug according to your description. See attached example
that works for me in PySide 1.1.0.
