Hello,
At the moment i need provide the possibility to add new tab dynamically.
The UI pattern that i would like to provide is equals to the firefox “Open a new tab” option - A button, with
+
caption, at the end of all tab captions.
Maybe when this button was clicked, an event may be fired… something like…
public void getNewTabComponent(Event event) {
if (canAddNewtab()) {
return createMayNewComponentTab();
}
return null;
}
Best regards
I didn’t worked with the TabSheet yet… but if it have a listenner you can make a tab with “+” and when you click it, you create a new tab and show it… I will try that latter ok!?

Hello Flavio,
At the moment, i made my own TabSheetPlus… and it is in sync with your sugestion.
public abstract class TabSheetPlus extends TabSheet {
private CssLayout plusTab;
private Component lastTab;
protected abstract Component getNewTabComponent();
public TabSheetPlus() {
plusTab = new CssLayout();
plusTab.setCaption("+");
addComponent(plusTab);
addListener(new TabSheet.SelectedTabChangeListener() {
public void selectedTabChange(SelectedTabChangeEvent event) {
Component selectedTab = getSelectedTab();
if (selectedTab.getCaption() != null && selectedTab.getCaption().equals("+")) {
setSelectedTab((lastTab != null ? lastTab : getComponentIterator().next()));
Component newTabComponent = getNewTabComponent();
if (newTabComponent != null) {
addTab(newTabComponent);
setSelectedTab(newTabComponent);
}
} else {
lastTab = selectedTab;
}
}
});
}
@Override
public Tab addTab(Component c, String caption, Resource icon) {
removeComponent(plusTab);
Tab tab = super.addTab(c, caption, icon);
super.addTab(plusTab, plusTab.getCaption(), null);
return tab;
}
Thanks!
One option would be to use Henrik’s
DetachedTabs
component.

It also a good idea to add a feature request ticket to the trac, so that there’s some official reference to this request. It might of course get turned down, but at least someone’s have to make a descision.
