Member Function Documentation
◆ elementById()
| QObject * Zbl::ZxItem::elementById | ( | const QString & | id | ) |
Obtain the element node from this node model that has the specified id attribute.
- Parameters
-
id the id value of the desired element (attribute must have type xs:ID)
- Returns
- the ZxItem object corresponding to the ID value or NULL if no model items were present in the sequence.

◆ getLocalName()
| const QString Zbl::ZxItem::getLocalName | ( | ) |
◆ getRootNode()
| QObject * Zbl::ZxItem::getRootNode | ( | ) |
Obtain the root node from the node model that contains this node.
- Returns
- the ZxItem object for this model's root node.

determine if this item is null
Definition at line 73 of file ZxItem.cpp.
◆ registerType()
|
static |
Registers ZxItem as a QML type.
Definition at line 40 of file ZxItem.cpp.
