Did you disable textBox1? This should not just be happening for free.
Setting enablement and focus while the error dialog is up should not be a
problem, the snippet below does it. Does the snippet work for you? And,
which platform and swt version are you using?
public static void main(String[] args) {
final Display display = new Display();
final Shell shell = new Shell(display);
shell.setLayout(new GridLayout());
final Text text1 = new Text(shell, SWT.SINGLE);
final Text text2 = new Text(shell, SWT.SINGLE);
shell.pack();
shell.open();
text2.setFocus();
text1.setEnabled(false);
display.timerExec(2222, new Runnable() {
public void run() {
final Shell child = new Shell(shell);
child.setLayout(new FillLayout());
Button button = new Button(child, SWT.PUSH);
button.setText("Push");
button.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
text1.setEnabled(true);
text1.setFocus();
child.dispose();
}
});
child.pack();
child.open();
while (!child.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
}
});
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}
