Build Identifier: 1 I wrote a demo to put a swt into canvas. In windows ,it is OK and could show two buttons. import org.eclipse.swt.*; import org.eclipse.swt.awt.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.widgets.*; public class SWTInAWT { public static void main(String[] args) { java.awt.Frame frame = new java.awt.Frame("AWT Frame"); java.awt.Button button = new java.awt.Button("AWT Button"); frame.add(button, java.awt.BorderLayout.NORTH); java.awt.Canvas canvas = new java.awt.Canvas(); frame.add(canvas, java.awt.BorderLayout.CENTER); frame.addNotify(); Display display = new Display(); Shell shell = SWT_AWT.new_Shell(display, canvas); shell.setLayout(new FillLayout()); Button swtButton = new Button(shell, SWT.PUSH); swtButton.setText("SWT Button"); frame.setBounds(20, 20, 300, 300); shell.layout(); frame.setVisible(true); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } } 2 when I run it in linux Redhat 5 EL, it will throwException.
