Hi,I am developing an "Editor" where i have added widgets in the using
SWT/JFace..When i proceeded with adding "menus" a strange thing is
happening..The window is showing only the menu with the 1 item i
added..but after resizing the window its showing the other widgets.like if
i MAXIMIZE it or RESIZE it with the MOUSE..
Please help me out of this situation..
I have used FormLayout to set the layout.
I am also sending the code along with this document..
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FormAttachment;
import org.eclipse.swt.layout.FormData;

import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.MenuItem;
import org.eclipse.swt.widgets.TabFolder;
import org.eclipse.swt.widgets.TabItem;
public class EditorTry4 extends ApplicationWindow
{
public EditorTry4()
{
super(null);
}
protected Control createContents(Composite parent)
{
getShell().setText("Graphical Custom Editor ");
getShell().setBounds(100,100,380,500);
int i;
GroupandTabfolder2 GT = new GroupandTabfolder2(parent);
return parent;
}
public static void main(String args[])
{
EditorTry4 ET4 = new EditorTry4();
ET4.setBlockOnOpen(true);
ET4.open();
Display.getCurrent().dispose();
}
}
class GroupandTabfolder2 extends Composite
{
public GroupandTabfolder2(Composite parent)
{
super(parent,SWT.NONE);
FormLayout layout = new FormLayout();
setLayout(layout);
