特性文档编制

column : index

This property holds the value used to match the column value of model elements.

delegate : 组件

This property holds the delegate to use if this choice matches the model item.

index : index

This property holds the value used to match the index value of model elements. This is effectively an alias for row .

roleValue : string

This property holds the value used to match the role data for the role provided by DelegateChooser::role .

row : index

This property holds the value used to match the row value of model elements. With models that have only the index property (and thus only one column), this property should be intended as an index, and set to the desired index value.

注意： Setting both row and index has undefined behavior. The two are equivalent and only one should be used.
