q: is this used in desktop aura?

[pkotwicz, 2014/10/01 14:45:03]

It is not used in desktop aura, but it makes sense to have this for consistency

[oshima, 2014/10/01 17:26:55]

If it's not used, I'd recommend to add TODO instead of adding dead code.
I'll defer to sky@ tho.

Depends upon what you mean by used. kCanMinimizeKey will be used to the same
extend kCanMaximizeKey is used. It's nice to propagate the value to the
underlying window in case someone queries it outside of the widget API.

   content_window_->SetProperty(aura::client::kCanResizeKey,
                                GetWidget()->widget_delegate()->CanResize());
   desktop_window_tree_host_->SizeConstraintsChanged();
