Detailed Description

Base class for widgets that deal with attribute associations.

Member Function Documentation

hasSelectedItem()

virtual bool smtk::extension::qtAssociationWidget::hasSelectedItem ( )

pure virtual

Return true if there are persistent objects selected.

This comes in handy when a parent group view changes tabs. With this you can prevent tab switching from changing selection state when returning to the view owning this widget

Implemented in smtk::extension::qtAssociation2ColumnWidget.

isValid()

virtual bool smtk::extension::qtAssociationWidget::isValid ( ) const

pure virtual

return true if the association information is valid.

Note that this not only can refer to the requirements related to the target attribute but also to requirements imposed by the View description such as requiring that all "appropriate" persistent objects be associated with an attribute of a specified type.

Implemented in smtk::extension::qtAssociation2ColumnWidget.
