As far as I know, the InputDialog is to be used when you need to fill
up exactly one value. Here is the class I wrote for me - it gets
Properties object on input. However, you may re-write it to get i.e.
Hashtable. And no validators now.
import java.util.Enumeration;
import java.util.Hashtable;
import java.util.Properties;
import org.eclipse.jface.dialogs.Dialog;
import org.eclipse.jface.dialogs.IDialogConstants;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
public class DynamicPropertyDialog extends Dialog {
private Properties properties;
private Hashtable controls;
public Properties getProperties() {
return properties;
}
public DynamicPropertyDialog(Shell parentShell, Properties props) {
super(parentShell);
this.properties = props;
this.controls = new Hashtable();
}
protected void okPressed() {
Enumeration keys = this.properties.keys();
while (keys.hasMoreElements()) {
String key = (String) keys.nextElement();
Text text = (Text) controls.get(key);
this.properties.setProperty(key, text.getText());
}
super.okPressed();
}
protected void createButtonsForButtonBar(Composite parent) {
super.createButtonsForButtonBar(parent);
if (this.controls == null || this.controls.size() == 0)
return;
Text first = (Text) controls.values().toArray()[0];
first.selectAll();
}
protected Control createDialogArea(Composite parent) {
Composite contentsComposite = new Composite(parent, SWT.NONE);
contentsComposite.setLayout(new GridLayout(2, false));
GridData gridData = new GridData(GridData.FILL_HORIZONTAL,
GridData.FILL_VERTICAL, true, true);
gridData.widthHint = convertHorizontalDLUsToPixels(IDialogConstants.
MINIMUM_MESSAGE_AREA_WIDTH);
contentsComposite.setLayoutData(gridData);
Enumeration keys = this.properties.keys();
while (keys.hasMoreElements()) {
String key = (String) keys.nextElement();
String value = this.properties.getProperty(key);
Label lbl = new Label(contentsComposite, SWT.NONE);
lbl.setText(key);
Text text = new Text(contentsComposite, SWT.BORDER);
text.setLayoutData(new GridData(GridData.GRAB_HORIZONTAL
| GridData.HORIZONTAL_ALIGN_FILL));
text.setText(value);
this.controls.put(key, text);
}
return contentsComposite;
}
}

I have been using wizards because they sized better than dialogs..
