Python QtCore.QModelIndex Beispiele

Beispiel #1

	def parent(self, index):
		if not index.isValid():
			return QtCore.QModelIndex()

		childItem = index.internalPointer()
		parentItem = childItem.parent()

		if parentItem == self.rootItem:
			return QtCore.QModelIndex()

		return self.createIndex(parentItem.row(), 0, parentItem)

Beispiel #2

	def index(self, row, column, parent):
		if not self.hasIndex(row, column, parent):
			return QtCore.QModelIndex()

		if parent is None or not parent.isValid():
			parentItem = self.rootItem
		else:
			parentItem = parent.internalPointer()

		childItem = parentItem.child(row)
		if childItem:
			return self.createIndex(row, column, childItem)
		else:
			return QtCore.QModelIndex()
