This is an abstract base class for any elements of a drag and drop form.
This class overrides mime type handling to be able to work with the drag and drop attribute editor.
int verticalStretch() const
Returns the vertical stretch factor for the element.
DnDTreeItemData(Type type, const QString &name, const QString &displayName, const QColor &backgroundColor=QColor())
@ WidgetType
In the widget tree, the type of widget.
int horizontalStretch() const
Returns the horizontal stretch factor for the element.
void setCollapsed(bool collapsed)
For group box containers sets if this group box is collapsed.
void setVerticalStretch(int stretch)
Sets the vertical stretch factor for the element.
void setHorizontalStretch(int stretch)
Sets the horizontal stretch factor for the element.
bool collapsed() const
For group box containers returns if this group box is collapsed.
