Hi everybody, i'm having trouble with this code:

import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.ControlAdapter;
import org.eclipse.swt.events.ControlEvent;
import org.eclipse.swt.events.FocusEvent;
import org.eclipse.swt.events.FocusListener;

public class wdw
{
public static void main(String[] args) {
Display dis = new Display();
final Shell s = new Shell(dis);
s.setLayout(new GridLayout(1, false));
s.setSize(300, 200);
Text t1=new Text(s, SWT.BORDER);
t1.setTextLimit(20);

Text t2=new Text(s, SWT.BORDER);
t2.setTextLimit(20);

final FocusListener listener = new FocusListener() {
public void focusGained(FocusEvent event) { }
public void focusLost(FocusEvent event) {
MessageBox msgBox = new MessageBox(s, SWT.ICON_INFORMATION|SWT.OK);
msgBox.setMessage("focus lost");
msgBox.setText("Focus lost");
msgBox.open();
}
};

t1.addFocusListener(listener);

s.open();
while (!s.isDisposed()) {
if (!dis.readAndDispatch())
dis.sleep();
}
dis.dispose();
}

after focuslost event in t1 when I click on OK button in message box the control return to t2 widget but is impossible to write in it.
Is it a swt bug?

Thanks in advance

Hi,

I can reproduce this, but doesn't happen always.
I noticed that after clicking OK, when the mouse is moved over the shell, mouse cursor sometimes changes to ibeam instead of arrow. When you click on the shell or textbox so that the arrow cursor appears, you can start typing again.

This looks like a bug to me. Can you please open a bug report under SWT --> https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=SWT

Thanks,

Lakshmi P Shanmugam
