Find custom View with bot [message #1845043]

Hi,
We have custom class extended from org.eclipse.jface.viewers.TreeWiewer and we need to test it. How can I get this widget with SWTBot? I tried this way:

 Display.getDefault().asyncExec(() -> {
           CustomTreeViewer customTreeViewer = bot.widget(WidgetMatcherFactory.widgetOfType(CustomTreeViewer.class));
            
        });

but "CustomTreeViewer.class" is underlined in red and the message says
Quote:

Required type:Class<T>
Provided: Class<PropertyTreeViewer>
reason: no instance(s) of type variable(s) exist so that PropertyTreeViewer conforms to Widget

So the question is there any opportunity to do this with bot?
Thanks in advance!

Hi Дарья,

This is failing because a TreeViewer is not a Widget. As far as I know it is not possible to access the TreeViewer from SWTBot.

You can however access the Tree that is returned by TreeViewer.getTree() using SWTBotTree.

If you have no other choice, you might be able to get a reference to the CustomTreeViewer for tests by storing it inside the Tree's data within your application, using setData()/getData() perhaps with a key. It's a bit hackish though.
