TTkTreeWidgetItem

class TTkTreeWidgetItem(*args, parent: TTkTreeWidgetItem | None = None, expanded: bool = False, hidden: bool = False, icon: str | TTkString = '', childIndicatorPolicy: ChildIndicatorPolicy = ChildIndicatorPolicy.DontShowIndicatorWhenChildless, **kwargs)

Bases: TTkAbstractItemModel

The TTkTreeWidgetItem class provides an item for use with the :py:class:’TTkTree’ convenience class.

Tree widget items are used to hold rows of information for tree widgets. Rows usually contain several columns of data, each of which can contain a TTkString label and an icon or a TTkWidget.

Items are usually constructed with a parent that is TTkTreeWidgetItem (for items on lower levels of the tree). For example, the following code constructs a top-level item to represent cities of the world, and adds a entry for Oslo as a child item:

cities = TTkWidgetItem(["Cities"])
osloItem = TTkWidgetItem(["Oslo"], parent=cities)

or

cities = TTkWidgetItem(["Cities"])
osloItem = TTkWidgetItem(["Oslo"]
cities.addChild(osloItem)
