vaadin 7 layout click doesn't work - vaadin7

Question

I've created MainGameTab which extends TabSheet.
In constructor I create layouts and add them as tabs. I wanted to add right click event to the layout
mainLayout.addLayoutClickListener(new LayoutClickListener() {
private static final long serialVersionUID = 1871942396979048283L;
#Override
public void layoutClick(LayoutClickEvent event) {
if (event.getButton() == MouseButton.RIGHT) {
TextQuestUi.getCurrent().addWindow(new CharacterSheet(c));
}
}
});
this.addTab(mainLayout, "Game");
CharacterSheet is a class, that extends Window
public class CharacterSheet extends Window {
But when I click on tab - I've got basic right click items for browser instead of new window.
What's the problem?
My MainGameTab looks like this
public MainGameTab() {
final Player c = new Player();
c.setName("Hero");
c.setLevel(100);
Skill skill = new Skill();
skill.setName("Help from heaven");
skill.setEffect("Full recover health");
c.addSkill(skill);
Stat stat = new Stat();
stat.setName("Attack");
stat.setValue(50);
c.addStat(stat);
HorizontalLayout mainLayout = new HorizontalLayout();
mainLayout.addLayoutClickListener(new LayoutClickListener() {
private static final long serialVersionUID = 1871942396979048283L;
#Override
public void layoutClick(LayoutClickEvent event) {
if (event.getButton() == MouseButton.RIGHT) {
TextQuestUi.getCurrent().addWindow(new CharacterSheet(c));
}
}
});
this.addTab(mainLayout, "Game");
HorizontalLayout logLayout = new HorizontalLayout();
this.addTab(logLayout, "Log");
}
And I add it in UI
#Override
protected void init(VaadinRequest request) {
this.setContent(new MainGameTab());
}

I'll suggest you to use one of the existing Vaadin addons. See here
Or, I am assuming that you're probably looking for getButton() in ItemClickEvent - something like this:
t.addListener(new ItemClickListener() {
public void itemClick(ItemClickEvent event) {
if (event.getButton()==ItemClickEvent.BUTTON_RIGHT) {
// Right mouse button clicked, do greatThings!
}
}
});
