Hi,
After the update on M3 (previously I had M1) is my DoubleClickListener on
TableViewer unreachable in Internet Explorer. In Firefox does the same
listener very good. Can anyone see the same behavior?
Here is my code:
tableViewer.addDoubleClickListener(new IDoubleClickListener()
{
public void doubleClick(DoubleClickEvent arg0)
{
doubleClickAction.run();
}
});
the expression "doubleClickAction.run()" is never reached in IE.
Regards,
Nikolai

Hallo Rüdiger,
I have reproduced it with ControlsDemo. This has what with FormToolkit to
do.
Here my code (sorry, if it is too large):
1)
--------------------------------------
--------------------------------------
a new class TableViewerTabDoubleClick:
--------------------------------------
package org.eclipse.rap.demo.controls;
import java.util.ArrayList;
import org.eclipse.jface.viewers.DoubleClickEvent;
import org.eclipse.jface.viewers.IDoubleClickListener;
import org.eclipse.jface.viewers.IStructuredContentProvider;
import org.eclipse.jface.viewers.ITableLabelProvider;
import org.eclipse.jface.viewers.LabelProvider;
import org.eclipse.jface.viewers.TableViewer;
import org.eclipse.jface.viewers.Viewer;
import org.eclipse.swt.SWT;
import org.eclipse.swt.custom.CTabFolder;
import org.eclipse.swt.custom.ScrolledComposite;
import org.eclipse.swt.graphics.Image;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.ui.forms.widgets.FormToolkit;
public class TableViewerTabDoubleClick extends ExampleTab {
private static final class Person {
String firstName;
String lastName;
int age;
public Person(final String firstName, final String lastName,
final int age) {
this.firstName = firstName;
this.lastName = lastName;
this.age = age;
}
public String toString() {
return firstName + " " + lastName + " " + age;
}
}
private static final class PersonContentProvider implements
IStructuredContentProvider {
Object[] elements;
public Object[] getElements(final Object inputElement) {
return elements;
}
public void inputChanged(final Viewer viewer, final Object oldInput,
final Object newInput) {
if (newInput == null) {
elements = new Object[0];
} else {
java.util.List personList = (java.util.List) newInput;
elements = personList.toArray();
}
}
public void dispose() {
// do nothing
}
}
private static final class PersonLabelProvider extends LabelProvider
implements ITableLabelProvider {
public Image getColumnImage(final Object element, final int columnIndex)
{
return null;
}
public String getColumnText(final Object element, final int columnIndex)
{
Person person = (Person) element;
String result;
switch (columnIndex) {
case 0:
result = person.firstName;
break;
case 1:
result = person.lastName;
break;
case 2:
result = String.valueOf(person.age);
break;
default:
result = "";
break;
}
return result;
}
}
private Table table;
private TableViewer viewer;
private final java.util.List persons = new ArrayList();
private ScrolledComposite scrolledComposite;
private FormToolkit formToolkit;
public TableViewerTabDoubleClick(final CTabFolder topFolder) {
super(topFolder, "TableViewerDoubleClick");
}
private void initPersons() {
persons.clear();
persons.add(new Person("Rögn\"íy&", "Hövl<, the char tester", 1));
persons.add(new Person("Paul", "Panther", 1));
persons.add(new Person("Karl", "Marx", 2));
persons.add(new Person("Sofia", "Loren", 3));
persons.add(new Person("King", "Cool", 4));
persons.add(new Person("Albert", "Einstein", 5));
persons.add(new Person("Donald", "Duck", 6));
persons.add(new Person("Mickey", "Mouse", 7));
persons.add(new Person("Asterix", "", 8));
persons.add(new Person("Nero", "", 9));
persons.add(new Person("Elvis", "Presley", 10));
}
protected void createStyleControls(final Composite parent) {
createStyleButton("MULTI", SWT.MULTI);
createStyleButton("VIRTUAL", SWT.VIRTUAL);
}
protected void createExampleControls(final Composite parent) {
parent.setLayout(new GridLayout(2, false));
GridData gridData = new GridData();
gridData.grabExcessHorizontalSpace = true;
gridData.verticalAlignment = GridData.FILL;
gridData.grabExcessVerticalSpace = true;
gridData.horizontalAlignment = GridData.FILL;
scrolledComposite = new ScrolledComposite(parent, SWT.V_SCROLL
| SWT.H_SCROLL);
scrolledComposite.setExpandHorizontal(true);
scrolledComposite.setExpandVertical(true);
scrolledComposite.setAlwaysShowScrollBars(false);
scrolledComposite.setLayoutData(gridData);
scrolledComposite.setLayout(new GridLayout());
initPersons();
table = getFormToolkit().createTable(scrolledComposite, SWT.NONE);
initColumnProperties();
table.setHeaderVisible(true);
table.setLinesVisible(true);
viewer = new TableViewer(table);
viewer.setContentProvider(new PersonContentProvider());
viewer.setLabelProvider(new PersonLabelProvider());
viewer.setInput(persons);
viewer.addDoubleClickListener(new IDoubleClickListener() {
public void doubleClick(DoubleClickEvent event) {
System.out.println("double-click");
}
});
scrolledComposite.setContent(table);
registerControl(scrolledComposite);
}
private FormToolkit getFormToolkit() {
if (formToolkit == null) {
formToolkit = new FormToolkit(Display.getCurrent());
}
return formToolkit;
}
private void initColumnProperties() {
TableColumn firstNameColumn = new TableColumn(table, SWT.NONE);
firstNameColumn.setText("First Name");
firstNameColumn.setWidth(170);
firstNameColumn.setMoveable(true);
TableColumn lastNameColumn = new TableColumn(table, SWT.NONE);
lastNameColumn.setText("Last Name");
lastNameColumn.setWidth(100);
lastNameColumn.setMoveable(true);
TableColumn ageColumn = new TableColumn(table, SWT.NONE);
ageColumn.setText("Age");
ageColumn.setWidth(80);
ageColumn.setMoveable(true);
}
}
-----------------------------------------------------
-----------------------------------------------------
End 1)
2.)
One new row in ControlsDemo.java after new TableViewerTab( topFolder ):
-----------------------------------------------------
-----------------------------------------------------
new TableViewerTabDoubleClick( topFolder ),
---------------------------------------------------
--------------------------------------------------
End 2)
3.) you need a plugin dependence in org.eclipse.rap.demo project to
org.eclipse.rap.ui.forms
--------------------------------------------------
---------------------------------------------------
end 3)
The code in createExampleControls method is the same as in my application
Attention:
if you replace
table = getFormToolkit().createTable(scrolledComposite, SWT.NONE);
with
table = new Table(scrolledComposite, SWT.NONE);
the doubleclick listener works in IE and FF.
with FormToolkit only in FF
regards,
Nikolai

Hi Nikolai,
thanks for the hint. Now I can reproduce what you described.
It is caused by the call to setForeground and/or setBackground that
takes place when using the FormToolkit to create the Table.
Would you file a bugzilla so that we can track progress on this issue?
Cheers,
Rüdiger
