Hello all,
I have run into a problem with my application. I need to be able to restore
the hierarchy as it is after I clear it and repopulate the list.
My current solution is to run through the items in the treewidget and
gather the list of indexes like so. I then iterate through the tree once it
has been cleared and repopulated and try to match up the indexes with the
old list:
It does not work, I believe that the indexes are changed on the refresh for
each item which is problematic, is there any way to keep the index of each
consistent?
I have come across persistent indexes but that is for QAbstractModel and I
am using QtreeWidget, I am unsure if the underlying model o fmy treewidget
is a QAbstractModel and if I can use persistent indexes.
def refreshWidget(self, filePath, xmlTree, displayWidget, fileType):
saveState = self.saveWidgetState(displayWidget)
config.uiViewCleared = True
displayWidget.clear()
config.uiViewCleared = False
self.xmlI_O.setUpTree(filePath, xmlTree, displayWidget,
fileType)
self.loadWidgetState(displayWidget, saveState)
def saveWidgetState(self, displayWidget):
print displayWidget.selectionModel()
expandedIndexes = {}
it = QtGui.QTreeWidgetItemIterator(displayWidget)
while it.value():
itemIndex = displayWidget.indexFromItem(it.value(), 0)
expandedItem = displayWidget.isItemExpanded(it.value())
expandedIndexes.update({itemIndex: expandedItem})
it += 1
return expandedIndexes
def loadWidgetState(self, displayWidget, expandedIndexes):
it = QtGui.QTreeWidgetItemIterator(displayWidget)
while it.value():
toExpand = [i for i in expandedIndexes if i ==
displayWidget.indexFromItem(it.value(),0)]
print "toExpand", toExpand
shouldExpand = expandedIndexes.get(toExpand[0])
if shouldExpand == True:
if not displayWidget.isItemExpanded(it.value()):
print "to expand", it.value().text(0)
displayWidget.expandItem(it.value())
it += 1
Cheers!
Ben
