Detailed Description

template<typename DerivedRenderApp>
class vcl::BlockerEventDrawer< DerivedRenderApp >

Special EventDrawer class for the case where the drawer can request to block the event propagation.

A drawer that inherits from this class can request to block the event propagation, and (if requested) the event will not be propagated to the other drawer arguments of the RenderApp class.

All the event functions of this class return a boolean value. If the function returns true, the DerivedRenderApp will block event propagation to other drawers; otherwise, the event is propagated to the other drawers.

Template Parameters

DerivedRenderApp

The type of the derived RenderApp class.
