GraphicalDisplayRenderer activeItem information is not available to subclasses

[clarencelocke]

What happened?

The GraphicalDisplayRenderer.activeItem ivar is inaccessible to subclasses, making it impossible to perform differential rendering of the item. There should be some mechanism (e.g., const MenuItem* getActiveItem() const or bool isActiveItem(const MenuItem* menuItem) const that can provide this information.

Version

• I have checked that I am using the latest version of the library.

What environment are you seeing the problem in?

My mistake... it looks like the hasFocus property is what I needed.. But it is still inaccessible.

Thanks for the follow-up. Two things:

1. activeItem is now exposed through new public accessors in fix: make GraphicalDisplayRenderer subclassable #433 — getActiveItem() and isActiveItem(const MenuItem*) — which should let you do differential rendering of the active item in your subclass.

2. Regarding your comment about hasFocus: in the latest master it is a protected member of MenuRenderer, so your GraphicalDisplayRenderer subclass can read this->hasFocus directly inside overridden methods such as drawItem. This is already on master and will ship with the next release.
