FormToolkit working in a standalone SWT/Jface app? [message #467239] Thu, 26 January 2006 21:16 Go to next message

I tried to use the FormToolkit in a swt/jface app, because I didn't see any reason that it shoudn't work outside of the eclipse platform. I couldn't have it render any single widget. Does the formToolkit run on in ViewParts?

No, you can run it standalone. There is nothing special that needs to be done. Just ensure that, you have the composite and the layouts properly in place, else you will not see anything. Infact this goes with any control. To get started, it is better to use fill layout, I guess, and then use, ScrolledComposite with GridLayout.

Well, here is a code snippet to create a TEXT-BOX with <B>ScrolledComposite</B> and a <B>GridLayout</B>.
Few things to note, else you will not see anything:
- Shell <B>must</B> have a layout
- While using a <I>ScrolledComposite</I>, <code>setLayoutData(...), setMinWidth(...), setMinHeight(...), setExpandHorizontal(...) and setExpandVertical(...)</code> <B>must</B> be used.

<code>
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.ScrolledComposite;
import org.eclipse.swt.graphics.Point;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;
import org.eclipse.ui.forms.widgets.FormToolkit;

public class FormToolkitExample
{
&nbsp;public static void main(String[] args)
&nbsp;{
&nbsp; &nbsp;Display display = new Display();
&nbsp; &nbsp;Shell shell = new Shell( display );
&nbsp; &nbsp;shell.setLayout( new GridLayout( 1, false));

&nbsp; &nbsp;ScrolledComposite scrlComposite = new ScrolledComposite( shell, SWT.H_SCROLL | SWT.V_SCROLL);
&nbsp; &nbsp;GridLayout gridScrlComposite = new GridLayout( 1, false);
&nbsp; &nbsp;scrlComposite.setLayout( gridScrlComposite);
&nbsp; &nbsp;scrlComposite.setLayoutData( new GridData( GridData.FILL_BOTH));

&nbsp; &nbsp;Composite composite = new Composite( scrlComposite, SWT.NONE);
&nbsp; &nbsp;scrlComposite.setContent( composite);
&nbsp; &nbsp;GridLayout gridComposite = new GridLayout( 1, false);
&nbsp; &nbsp;composite.setLayout( gridComposite);
&nbsp; &nbsp;composite.setLayoutData( new GridData( GridData.FILL_BOTH));

&nbsp; &nbsp;FormToolkit formToolkit = new FormToolkit( display);
&nbsp; &nbsp;formToolkit.paintBordersFor( composite);

&nbsp; &nbsp;Text txtField = formToolkit.createText( composite, "", SWT.NONE );

&nbsp; &nbsp;Point p = composite.computeSize( SWT.DEFAULT, SWT.DEFAULT, true );
&nbsp; &nbsp;scrlComposite.setMinWidth( p.x );
&nbsp; &nbsp;scrlComposite.setMinHeight( p.y );

&nbsp; &nbsp;scrlComposite.setExpandHorizontal( true );
&nbsp; &nbsp;scrlComposite.setExpandVertical( true );

&nbsp; &nbsp;shell.pack();
&nbsp; &nbsp;shell.open();

&nbsp; &nbsp;while ( !shell.isDisposed() )
&nbsp; &nbsp;{
&nbsp; &nbsp; &nbsp;if ( !display.readAndDispatch() )
&nbsp; &nbsp; &nbsp; &nbsp;display.sleep();
&nbsp; &nbsp;}
&nbsp; &nbsp;display.dispose();
&nbsp;}
}
