Text.getSelectionText() [message #640002]

I implemented a right cick context menu on a Text widget for copy using Javascript, but I found a problem in the text selection.

The getSelectionText method of the Text widget returns the selected text shifted 2 chars to the right. For example, if the text is "Hello world" and the selected text is "Hello", the getSelectionText method will return "llo W".

I tried using the setFocus() before getSelectionText but it did not help. Using the debugger I can see that the x and y are incorrect in the Text widget.

Did anyone had that problem too?

This is for sure a bug. In Mozilla Forefox the getSelectionText method returns the correct text. The problem exists only in IE.

Hi Daniel,
I can't reproduce it with current CVS HEAD and Controls Demo -> Text Tab
under IE8 (Windows 7). Could you provide more information about the RAP
and IE versions used.
A snippet to reproduce it will help too.
Best,
Ivan

I'm using IE version 8.0.7600.16385 on Windows 7, and org.eclipse.rap.ui version 1.3.1.20100915-2301

I have a single widget in my view (Text). I created a context menu on that Text widget (not the view). One of the Action is called Copy and here what it does

String x = text.getSelectionText();
System.out.println(x);

Hi Daniel,
I can't reproduce it with RAP 1.3.1 either. Please file a bugzilla with
a self-running snippet to reproduce it.
Thanks,
Ivan

The bug exists only when you append an end of line to the Text widget. For example use text.append("This is a test line\r\n"); and then System.out.println(text.getSelectionText());

You can use the following to reproduce the problem. For example select the "test" word in the view, right click, select Copy. The output is "st li" instead of "test". If you want I can send you my test plug-in that recreates this problem.

This is the SampleView.java

package test.get.selection.views;

import org.eclipse.jface.action.MenuManager;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Menu;
import org.eclipse.swt.widgets.Text;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.actions.ActionFactory;
import org.eclipse.ui.actions.RetargetAction;
import org.eclipse.ui.part.ViewPart;

import test.get.selection.ActionCopy;
import test.get.selection.Activator;

public class SampleView extends ViewPart 
{
    public static final String ID = "test.get.selection.views.SampleView"; //$NON-NLS-1$

    private Text text;

    private RetargetAction actionCopyRetarget;
    private ActionCopy actionCopy;


    @Override
    public void createPartControl(Composite parent)
    {
        text = new Text(parent, SWT.MULTI | SWT.H_SCROLL | SWT.V_SCROLL | SWT.READ_ONLY);
        text.append("This is a test line\r\n");
       
        createActions();

        MenuManager menuManager = new MenuManager("ConsolePopupMenu"); //$NON-NLS-1$
        menuManager.setRemoveAllWhenShown(false);

        menuManager.add(actionCopyRetarget);
        menuManager.update(true);

        Menu menu = menuManager.createContextMenu(parent);
        text.setMenu(menu);
    }

    @Override
    public void setFocus()
    {
    }

    private void createActions()
    {

        IWorkbenchWindow window = Activator.getDefault().getWorkbench().getActiveWorkbenchWindow();

        actionCopyRetarget = (RetargetAction) ActionFactory.COPY.create(window);
        actionCopy = new ActionCopy(text);
        this.getViewSite().getActionBars().setGlobalActionHandler(actionCopyRetarget.getId(), actionCopy);
    }

}

and this is the ActionCopy.java

package test.get.selection;

import org.eclipse.jface.action.Action;
import org.eclipse.swt.widgets.Text;

public class ActionCopy extends Action
{

    private final static String ACTION_ID = "test.get.selection.copyAction"; //$NON-NLS-1$

    private Text text;

    public ActionCopy(Text text)
    {
        this.text = text;
        setId(ACTION_ID);
    }

    @Override
    public void run()
    {
        System.out.println(text.getSelectionText());
    }

    public void setEnabled()
    {
        setEnabled(text.getSelectionCount() > 0);
    }

}

Hi Daniel,
I can reproduce it with your snippet and IE8 under Windows 7. Please
file a bugzilla to track the progress on this issue. Please attach this
code to the bug.
Thanks,
Ivan
