That is my problem, and why I ask if somebody know anything about this.
Because, normaly it append after a memory leak (in C/C++ and others), but in
python we do not manage our memory that's my problem.
Ok, here is a bit more of my code.
It's in my own model:
def addIndividu(self, index, lIndividu):
self.beginRemoveRows(
index,
self.rowCount(index),
self.rowCount(index))
# We add the data in the node
node = index.internalPointer()
dProblem = node.addIndividu(lIndividu)
if dProblem is not None and dProblem != {}:
wChapterSelection =
WindowChapterSelectionDialog.WindowChapterSelectionDialog() # <- We create
an instance of the window
# First we verify that all item have a valid type
if dProblem.get('undefied_type') is not None:
dUndef = dProblem.pop('undefied_type')
for typeIndividu in dUndef:
lChapter = dUndef[typeIndividu][0]
lIndividu = dUndef[typeIndividu][1]
for individu in lIndividu:
wChapterSelection.setWindow(typeIndividu, individu,
lChapter)
wChapterSelection.exec_() # <- HERE IS MY PROBLEM !!
: "bus error"
if wChapterSelection.Accepted ==
wChapterSelection.result():
goodChapter = wChapterSelection.getSelection()
goodChapter.addIndividu([individu])
The problem is steel there if I do something like:
def addIndividu(self, index, lIndividu):
self.beginRemoveRows(
index,
self.rowCount(index),
self.rowCount(index))
# We add the data in the node
node = index.internalPointer()
dProblem = node.addIndividu(lIndividu)
if dProblem is not None and dProblem != {}:
wChapterSelection = QtgGui.QDialog() # <- We create an instance
of the window
# First we verify that all item have a valid type
if dProblem.get('undefied_type') is not None:
dUndef = dProblem.pop('undefied_type')
for typeIndividu in dUndef:
lChapter = dUndef[typeIndividu][0]
lIndividu = dUndef[typeIndividu][1]
for individu in lIndividu:
wChapterSelection.exec_() # <- HERE IS MY PROBLEM !!
: "bus error"
if wChapterSelection.Accepted ==
wChapterSelection.result():
print "ok :)"
Thanks for your help
