[Win32] For a Text field with SWT.Verify-listener the Shift+Del shortcut does not work any more

[tmssngr]

Describe the bug
Normally, the legacy shortcut Shift+Del cuts text in a text field on Windows. This works fine by default until you add a SWT.Verify listener to the Text control.

To Reproduce
Run this snippet:

import org.eclipse.swt.*;
import org.eclipse.swt.layout.*;
import org.eclipse.swt.widgets.*;

public class TextTest {

	public static void main(String[] args) {
		final Display display = new Display();
		final Shell shell = new Shell(display);
		shell.setLayout(new GridLayout(1, false));
		final Text text = new Text(shell, SWT.SINGLE | SWT.BORDER);
		text.setLayoutData(new GridData(SWT.FILL, SWT.TOP, true, false));
		text.setText("Hello World");
		text.setSelection(6, text.getCharCount());
/*
		text.addListener(SWT.Verify, event -> {
			System.out.println("verify called");
		});
*/

		shell.setSize(400, 100);
		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}
		display.dispose();
	}
}

on Windows and press Shift+Del. "World" will be cut. Now uncomment the SWT.Verify listener and run again. Now Shift+Del does not cut any more.

Expected behavior
Shift+Del should work regardless of the SWT.Verify listener.

Environment:

1. Select the platform(s) on which the behavior is seen:

• • All OS
• • Windows
• • Linux
• • macOS

2. Additional OS info (e.g. OS version, Linux Desktop, etc)
   Tried on Windows 11.

And not just when a verify listener is added to the Text control. It can happen when a Text control is in a wizard or dialog. For example, the Text fields in Eclipse's Preferences pages.

Edit - I was mistaken. Ignore above.

Does not happen in RCP when there is a custom Command for that key binding (default):

reproducable in Large File Associations preferences:

@jukzi Do these text fields contain an SWT.Verify listener?

[jukzi]

yes
