Hi,

I've found another SWT_AWT bridge problem. I've created an AWT frame using
the SWT_AWT bridge and added a JPanel to it.
On this I've changed the cursor type, but it seems to be some problems with
this. The cursor appears only after resizing and only in a limited area
instead on the entire window.
I've tested the same snippet without the SWT_AWT bridge and works fine.
The snippet was tested using the vm from JDK 1.4.2_08-b03 and SWT version
3.123 on Windows 2000.

Below is the snippet:

import java.awt.CardLayout;
import java.awt.Cursor;
import java.awt.Frame;

import javax.swing.JPanel;
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());

System.getProperties().list(System.out);

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) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (UnsupportedLookAndFeelException e) {
e.printStackTrace();
}

JPanel panel = new JPanel(true);

panel.setCursor(new Cursor(Cursor.CROSSHAIR_CURSOR));

frame.add(panel);
frame.setLayout(new CardLayout());
frame.pack();


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

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


Best regards,
Boby

I entered the following bug report and added you to the CC:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=95540

In the future, if you find a bug, it is best to track the resolution with a
bug report rather than a newsgroup posting.

I believe you need to create a Panel, not a JPanel as a child of the Frame.
See the Javadoc for new_Frame().

Not only do you need a Panel as the first child, if you want to put
Swing components in it and have them function properly you need a
RootPaneContainer as well. Note that Javasoft did not write a standalone
RootPaneContainer.
