Actually .. I think there's still an annoying lifetime issue here. parent_ could
be a destroyed NativeWindow at this point :/

You could add a WidgetObserver (if it is non-null)... but that kinda defeats the
point of the refactor.

I think an alternative might be to create the widget with
CreateBrowserModalDialogViews in the constructor. Then override
DialogDelegate::OnClosed() in ExtensionUninstallDialogDelegateView, which calls
dialog_->ExtensionUninstallCanceled().

Then Show() should be:

  if (view)
    view_->GetWidget()->Show();


But if you go this route, I think you will still need that `refresh icon` call.
Maybe wait for the DialogDelegate experts to weigh in :)


Part of me is even thinking a nicer solution would just be to scrap the
uninstall dialog code completely and just make "uninstall" another sub-type of
the "install" dialog that doesn't show permissions and has different buttons.

Opened crbug.com/397396 to track this and added a todo.

[tapted, 2014/07/24 07:09:55]

nit: not stuff you're adding, but it's really confusing having `icon` (an
ImageSkia), and `icon_` (an ImageView). Perhaps rename the ImageSkia `icon`
argument to `image`

[sashab, 2014/07/24 08:02:14]

Np, agreed, this was confusing me earlier. Done.
