Hello,
I am trying to use a HorizontalPanel for a navigation bar that I am
building with a loop. The code looks like this:
<code>
HorizontalPanel navigation = new HorizontalPanel();
int count = 0;
for (final String name : artists.keySet()) { // artists is an
instance of a LinkedHashMap<String, Object>
count++;
// create the link
Anchor link = new Anchor(name, "");
if (artists.size() == count) {
link.addStyleName("last");
}
link.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
/// ...
}
});
// add to navigation
navigation.add(link);
}
</code>
If there is only 1 item in the list of artists it works, however if
there is another one added nothing shows up. I tried debugging it in
eclipse and the only thing odd (when i inspected navigation) is that
the text in navigation>children>array>[1]=Anchor (id=474) shows up red
(where [0]=Anchor (id=470) shows up black). Also the size property of
the children says 2 but is also in red.
The toString() of navigation shows the table with the 2 anchors
properly added, just doesnt show up on the page.
Also, I am new to GWT so any suggestions on code improvement for
accomplishing the above would be appreciated.
Thanks!
