PyQt: Put multiple QTreeWidgetItems in QTreeWidget columns
I made a function that allows you to add an element to the tree (parent + child or children).
def addItemsToSummary(self, parent, text, checkable=False, expanded=True):
self.tabItems = []
self.tabParent.append(text)
self.item = QTreeWidgetItem(parent, [text])
lhs, rhs = self.item.text(0).split("=", 1)
self.nominalValue,_ = rhs.split(")", 1)
print(self.nominalValue)
self.val = re.findall('\w+', self.nominalValue)
print(self.val)
print(self.val[0])
print(self.val[1])
if checkable:
self.item.setCheckState(0, Qt.Unchecked)
else:
self.item.setFlags(self.item.flags() & ~Qt.ItemIsUserCheckable)
self.item.setExpanded(expanded)
self.addChildToSummary(self.item, ["Nominal value = ", self.val[0], self.val[1]])
self.addChildToSummary(self.item, ["Min =","",self.val[1]])
self.addChildToSummary(self.item, ["Max =","",self.val[1]])
self.addChildToSummary(self.item, ["Type = ", "float",''])
self.addChildToSummary(self.item, ["Relation =","",""])
if self.tabItems is not None:
self.tabAnalysis.append(self.tabItems)
return self.tabAnalysis, self.nominalValue
I made another function that allows you to add each child to an element (parent).
def addChildToSummary(self, parent, tab):
item1 = QTreeWidgetItem(parent, [tab[0]])
item2 = QTreeWidgetItem(parent, [tab[1]])
item3 = QTreeWidgetItem(parent, [tab[2]])
item2.setFlags(item2.flags() | Qt.ItemIsEditable)
self.tabChild.append((item1.text(0),item2.text(0),item3.text(0)))
print(item2.text(0))
self.tabItems.append([parent.text(0),(item1.text(0),item2.text(0),item3.text(0))])
return item1, item2, self.tabItems
I would like to know if it is possible to put each QTreeWidgetItem
in a column QTreeWidget
.
