Class SelectionAdapterFileDialog<T>

java.lang.Object

org.eclipse.swt.events.SelectionAdapter

org.pentaho.di.ui.core.events.dialog.SelectionAdapterFileDialog<T>

All Implemented Interfaces:

EventListener, org.eclipse.swt.events.SelectionListener, org.eclipse.swt.internal.SWTEventListener

Direct Known Subclasses:

SelectionAdapterFileDialogText, SelectionAdapterFileDialogTextVar

public abstract class SelectionAdapterFileDialog<T>
extends org.eclipse.swt.events.SelectionAdapter

This adapter class opens up the VFS file dialog, where the primary goal is to select a file. This adapter class provides default implementations for the methods described by the SelectionListener interface. Classes that wish to deal with SelectionEvents can extend this class and override only the methods which they are interested in. example use: Dialog.java wbFilename.addSelectionListener( new SelectionAdapterFileDialogTextVar( log, wFilename, transMeta, new SelectionAdapterOptions( SelectionOperation.FILE, new FilterType[] { FilterType.TXT, FilterType.CSV, FilterType.ALL }, FilterType.TXT ) ) ); Side effect: wFilename#setText() will be called with chosen file.
