Check or Un-check a Menu Item

A menu item which was registered as being “checkable” can have its check state changed from IMenuManager using the following code: 

// The physical path of the menu item, indicating it's path hierarchy.
string[] menuPath = new[] { "_View", "_Fullscreen" };
 
// The checked state of the menu item.
bool isChecked = true;
 
menuManager.SetIsEnabled(isChecked, menuPath);
