Checking Tree Items

[rcraddock]

Hi,

I'm trying to write a check that there are only certain items displayed in my Tree View, but I'm having trouble accessing the underlying Tree.

I have a TreeItemLocator that gets me to the top of the branch I wish to check, and I'm sure I can get the children once I have the actual TreeItem, I juts can't make the leap from the Locator to the actual widget in this case.

I'm sure it must be something to do with WidgetReferences, and that I'm just having a bad Monday morning

Thanks,

Richard

Something like this should work:

Code: Select all

IWidgetReference ref = (IWidgetReference)ui.find(new TreeItemLocator(...));
final TreeItem item = (TreeItem)ref.getWidget();

With the tree item in hand, you should be able to get at the tree like this:

Code: Select all

Tree tree = item.getParent();

and it's children like so:

Code: Select all

TreeItem[] items = tree.getItems();

Do note that you'll have to be mindful to access the widgets on the UI thread (and not the test thread). In other words, wrap the above in a runnable passed to the display something like this:

Code: Select all

Display.getDefault().syncExec(new Runnable() {
   public void run() {
      Tree tree = item.getParent();
      TreeItem[] items = tree.getItems();
      ...
   }
});

Finally, what are you trying to assert? Perhaps we can help you craft a custom condition?

Hope this helps.
