Question

I have tried an example using SashForm in Linux.
Its displaying well if I use FillLayout for my Shell.
but SashForm and its contents are not displayed if
I use GridLayout for Shell.
I have given my code below.
Please help me in this issue.
Thanks in advance
import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.Panel;
import org.apache.batik.swing.JSVGCanvas;
import org.eclipse.swt.*;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.custom.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
public class SashTest {
public static void main (String [] args) {
final Display display = new Display ();
Shell shell = new Shell(display);
shell.setLayout (new GridLayout(1,true));
GridData data = new GridData(GridData.FILL_BOTH);
Composite comp = new Composite(shell, SWT.EMBEDDED|SWT.BORDER);
comp.setLayout(new FillLayout());
comp.setLayoutData(data);
SashForm sashForm = new SashForm(comp,SWT.HORIZONTAL|SWT.EMBEDDED|SWT.BORDER);
sashForm.setLayout(new FillLayout(SWT.HORIZONTAL));
Composite ctreeComp= new Composite(sashForm,SWT.BORDER);
ctreeComp.setLayout(new FillLayout());
Tree cTree = new Tree(ctreeComp, SWT.SINGLE | SWT.BORDER);
for(int i=0;i TreeItem items = new TreeItem(cTree, SWT.NULL);
items.setText("Treeitem "+i);
Composite cgComp = new Composite(sashForm, SWT.BORDER|SWT.EMBEDDED);
cgComp.setLayout(new FillLayout());
sashForm.setWeights(new int[]{20,80});
//Setting up canvas for rendering process wise communication graphs
Frame pcFrame = SWT_AWT.new_Frame(cgComp);
Panel cPanel = new Panel(new BorderLayout());
pcFrame.add(cPanel);
cPanel.add(new JSVGCanvas());
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
display.dispose ();
}

Mario,
Open Source drivers for our DAQ products are developed by the Comedi project. It should be noted that these drivers may not contain the full functionality of the NI-DAQ driver available for E Series devices under the various Windows and Mac operating systems.
For information regarding the Comedi Project please see http://stm.lbl.gov/comedi. Support for the Comedi drivers is available through the Comedi mailing list. Please contact the Comedi mailing list for questions regarding this Open Source driver.
