QTreeWidgetItem Class Reference |
Constant | Value |
---|---|
QTreeWidgetItem::ShowIndicator | 0 |
QTreeWidgetItem::DontShowIndicator | 1 |
QTreeWidgetItem::DontShowIndicatorWhenChildless | 2 |
This enum was introduced in Qt 4.3.
This enum describes the types that are used to describe tree widget items.
Constant | Value | Description |
---|---|---|
QTreeWidgetItem::Type | 0 | The default type for tree widget items. |
QTreeWidgetItem::UserType | 1000 | The minimum value for custom types. Values below UserType are reserved by Qt. |
You can define new user types in QTreeWidgetItem subclasses to ensure that custom items are treated specially; for example, when items are sorted.
