Hi,

I'm using the SWT_AWT bridge to create an AWT frame. On this frame I've
created a JScrollPane and added a custom scrollable Label to this pane. The
problem is that when I push the ALT key down I get the following stacktrace:

java.lang.NullPointerException

Anyone could help me ?

Can you enter a bug report with the code? Thanks.

Hi Steve,

I wrote a snippet to introduce a bug report and found out that this
exception is generated only if I set the look and feel to system LF.

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClass Name());


Bellow is the snippet:

import java.awt.Frame;

import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;

import org.eclipse.swt.SWT;
import org.eclipse.swt.awt.SWT_AWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class SWTAWTTest {
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new FillLayout());

Composite container = new Composite(shell, SWT.EMBEDDED);
container.setLayout(new FillLayout());

Frame frame = SWT_AWT.new_Frame(container);

try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClass Name());
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (UnsupportedLookAndFeelException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

shell.pack();
shell.open();

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

If you still think that this is a SWT_AWT bridge problem I will enter a bug
report with this snippet attached to it.

Thanks and regards,
Boby
