Hello,
I'm encountering a strange problem when drawing a group widget and trying to
include/embed other widgets on, those widgets do not display. Why ??
Here is a code sample:
------------------------------------------------------------ ------------------------------------------------------------ -------------------------------
import org.eclipse.swt.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
/**
* @author admin
*
* TODO To change the template for this generated type comment go to
* Window - Preferences - Java - Code Style - Code Templates
*/
public class testGroup1
{
private static boolean internalCall;
public static void main(String[] argc)
{
Display display = new Display();
Shell shell = new Shell(display);
internalCall = true;
GridLayout layout = new GridLayout(3, false);
layout.makeColumnsEqualWidth = true;
layout.marginHeight = 10;
layout.marginWidth = 10;
shell.setLayout(layout);
Label lblName = new Label(shell, SWT.NONE);
lblName.setText("Name");
GridData grid1 = new GridData();
grid1.horizontalSpan = 1;
lblName.setLayoutData(grid1);
Text text = new Text(shell, SWT.BORDER);
GridData grid2 = new GridData(GridData.FILL_HORIZONTAL);
grid2.horizontalSpan = 2;
text.setLayoutData(grid2);
Group group = new Group(shell, SWT.SHELL_TRIM);
group.setText("Group 1");
GridData grid3 = new GridData(GridData.FILL_BOTH);
grid3.horizontalSpan = 3;
group.setLayoutData(grid3);
//----------------------------------------------------------
// Next two controls (widgets) are not appearing. Why ??
//----------------------------------------------------------
Label one = new Label(group, SWT.LEFT);
one.setText("Name");
Text two = new Text(group, SWT.BORDER);
shell.setSize(400, 400);
shell.pack();
shell.open();
while(!shell.isDisposed()){
if(display.readAndDispatch())
display.sleep();
}
if(internalCall) display.dispose();
}
}

You didn't set a layout on your group:
Group group = new Group(shell, SWT.SHELL_TRIM);
group.setText("Group 1");
GridData grid3 = new GridData(GridData.FILL_BOTH);
grid3.horizontalSpan = 3;
group.setLayoutData(grid3);
group.setLayout(new anyLayout());
