Cannot display icon on dynamically displaying tab...

[jcubeta]

SmartGWT version: v8.2p_2012-10-31/Pro Deployment (built 2012-10-31)

I have a tab in my application that hides or shows depending upon a condition. I also want to display an icon on this dynamic tab at times. However, I cannot seem to get this working. I've included some sample code that basically describes what I'm doing.

Note that, for the tabs that are permanent, I can display the icon just fine.

Any help would be greatly appreciated. Let me know if you have questions or need further information.

private TabSet tabs;

public void makeTabSet() {
   tabs = new TabSet();
   tabs.addTab(createTab("A", /* make A's panel */ ), 0);
   tabs.addTab(createTab("B", /* make B's panel */ ), 1);
   tabs.addTab(createTab("C", /* make C's panel */ ), 2);
}

private Tab createTab(String title, Canvas pane) {
   Tab t = new Tab(title);
   t.setID(title);
   t.setPane(pane);
   return t;
}

private void hideDynamicTab() {
   Tab t = tabs.getTab("B");
   tabs.updateTab(t, null);
   tabs.removeTab(t);
}

private void showDynamicTab() {
   Tab t = tabs.getTab("B");
   if (t == null) {
      tabs.addTab(createTab("B", /* make B's panel */ ), 1);
   }
}

private void showIconOnDynamicTab() {
   Tab t = tabs.getTab("B");
   t.setIcon("path/to/icon.png");
}

private void hideIconOnDynamicTab() {
   Tab t = tabs.getTab("B");
   t.setIcon(null);
}

Have an additional icon when a tab is closable currently requires adding the icon as HTML in the Tab's title - see this thread.

OK, I've made the following change to my code based on the suggestion in the other thread, but it still doesn't work:

private void showIconOnDynamicTab() {
   Tab t = tabs.getTab("B");
   t.setTitle("<span>" + Canvas.imgHTML("/path/to/icon.png") + " B</span>");
   // t.setIcon("path/to/icon.png");
}

private void hideIconOnDynamicTab() {
   Tab t = tabs.getTab("B");
   t.setTitle("B");
   // t.setIcon(null);
}

Can you elaborate on "doesn't work"?

[jcubeta]

The icon does not display.

tabSet.setTabTitle() is the appropriate way to change a tab's title after draw.

tabSet.setTabTitle(...) did the trick! Thank you!
