getComposite

public Composite getComposite()

Description copied from interface: IUserInputWidget

Returns composite that is encapsulated in this object.

Returns:

composite where all controls are placed.

getNames

public List<QName> getNames()

Returns names of actually selected attributes. On error, function sets error message and returns null.

Returns:

list of names, or null if fillData() fails.

getValues

public List<String> getValues()

Returns text values of attributes. On error, function sets error message and returns null.

Returns:

fillData

protected void fillData()

Fills the _names, _values lists and the _namespaces set. The tab control must not yet be disposed.

If any combobox does not have name selected then function fails - it sets both lists to null and exits, returning non-null error message. If any attribute has illegal value, then function sets error message and fails.

getMessages

public ValidityMessages getMessages()

Description copied from interface: IUserInputWidget

Checks if data contained in the widget are correct. Contains error/info/warning messages that occured during last data change.

Returns:

null if data is correct, or instance of ValidityMessages if there is error, warning or info message.

public void setState(Object state)

Description copied from interface: IUserInputWidget
