This class determines if the window handle for these messages matches either the
handle for the
EngineDisplayForm
, which contains the entire editor interface, or
the
DisplayPanel
, which is a placeholder for the graphics display rendered by the
EditorHumanView
. If this were a message that occurred on another part of the edi-
tor, such as the game assets tree or the component editor,
PreFilterMessage()
would simply ignore the message.
One message that the C# editor application needs to trap is
WM_LBUTTONUP
. This
will call
EngineDisplayForm::SelectActor()
so that you can click directly on
the actor you are
interested in and have
its properties
show up in the
ActorPropertiesForm
.
