Hi,
I'm trying to update the provided TabbedPanel to be able to provide a new
CSS style to each tab so I can control the color of each tab.
I tried subclassing TabbedPanel and adding this method:
@Override
protected void onBeforeRender() {
super.onBeforeRender();
// get each tab and add a style
for (int i = 0; i < getTabs().size(); i++) {
Component tab = get("tabs-container:tabs:" + i);
tab.add(new AttributeAppender("class", true, new Model("tab"+i),
" "));
}
}
This doesn't work (Null Pointer) because this method gets called before the
actual tabs are added. I tried using onAfterRender(). This time the tabs
exist, but I can't modify the hierarchy during rendering.
Is there a way I can accomplish what I want without forking the TabbedPanel
class?
Thanks for your help,
Erik
