Method Detail
-
isAvailable
public boolean isAvailable()
Description copied from class:AbstractTableLoadDialog
The default implementation returns true.- Specified by:
isAvailable
in interfaceTableLoadDialog
- Overrides:
isAvailable
in classAbstractTableLoadDialog
- Returns:
- true iff this dialogue may be able to do something useful
-
configure
public void configure(StarTableFactory tfact, javax.swing.Action submitAct)
Description copied from interface:TableLoadDialog
Provides some configuration which must be performed before use. This method should be called beforeTableLoadDialog.getQueryComponent()
is called.The
tfact
argument provides a table factory which resembles the one to be used for generating tables. Although this factory should not in general be used or retained, since the one presented later to the TableLoader should be used instead, it can be interrogated for known table formats etc.The
submitAct
argument sets the action which when invoked will causeTableLoadDialog.createTableLoader()
to be called. Its setEnabled method can be called to reflect readiness, and it can be added as a listener to dialogue-specific events which indicate that a selection has been made.- Specified by:
configure
in interfaceTableLoadDialog
- Overrides:
configure
in classAbstractTableLoadDialog
- Parameters:
tfact
- representative table factorysubmitAct
- action for load submission
-
createQueryComponent
protected java.awt.Component createQueryComponent()
Description copied from class:AbstractTableLoadDialog
Constructs the query component used by this dialogue. Called only once (lazily).- Specified by:
createQueryComponent
in classAbstractTableLoadDialog
- Returns:
- query component
-
createTableLoader
public TableLoader createTableLoader()
Description copied from interface:TableLoadDialog
Returns a new object which specifies how table loading is to be performed. The actions performed by the returned object will presumably be determined by the state at call time of this dialogues GUI component.If the dialogue is not in a suitable state, either return null, or, if you want to provide more detailed information about what's wrong, throw a RuntimeException with an informative message.
- Returns:
- new table loader object
