Selecting text in multiple Text widgets simultaneously with SWT.MULTI style - can I stop this? [message #494772]

I've added several Text widgets to a Composite, each Text widget has the SWT.MULTI style.
On Windows, as well as allowing the Text to span multiple lines, and for selection to span multiple lines, it also allows you to select text in multiple Text widgets simultaneously. However, only the last selection is copied.For comparison, Linux/GTK only permits a selection in one Text.

See attached for example.

Does anyone know if this behavior is by design, and in any case how to work around it?

Fine.... don't let me attach this then Sad

---------------------------

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.RowLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

/**
* Interactive test to demonstrate multiply selected text boxes.
*/
public class MultipleSelectedTextBoxes {

public static void main(final String[] args) {
final Shell shell = new Shell();
shell.setSize(100, 300);
shell.setLayout(new RowLayout(SWT.VERTICAL));
new Text(shell, SWT.MULTI).setText("selectMe\nselectMe");
new Text(shell, SWT.MULTI).setText("selectMeToo\nselectMeToo");

shell.layout();
shell.open();

final Display d = shell.getDisplay();
while (!d.isDisposed()) {
if (!d.readAndDispatch()) {
d.sleep();
}
}
}

}

Hi,

This is logged as https://bugs.eclipse.org/bugs/show_bug.cgi?id=216666 .
Reading the report, it's believed that this is native behaviour, but there
aren't other native apps sited to prove/disprove this. If you're able to
find a native app that demonstrates that this behaviour is wrong then please
add a comment to the report with it, and it may serve as a catalyst for
investigating this further.

The only workaround I can think of is to add focus in/out listeners to the
Texts and clear/set the selection when needed.
