Member Function Documentation

◆ addContainer()

QTreeWidgetItem * QgsAttributesDnDTree::addContainer ( QTreeWidgetItem *  parent,
const QString &  title,
int  columnCount 

Definition at line 1009 of file qgsattributesformproperties.cpp.

◆ addItem()

QTreeWidgetItem * QgsAttributesDnDTree::addItem ( QTreeWidgetItem *  parent,
QgsAttributesFormProperties::DnDTreeItemData  data,
int  index = -1,
const QIcon &  icon = QIcon() 

Adds a new item to a parent.

If index is -1, the item is added to the end of the parent's existing children. Otherwise it is inserted at the specified index.

◆ dragMoveEvent()

void QgsAttributesDnDTree::dragMoveEvent ( QDragMoveEvent *  event)

Is called when mouse is moved over attributes tree before a drop event.

Used to inhibit dropping fields onto the root item.
