Member Function Documentation

handleInputEvent()

GUI::EventResult ImFusion::LabelingManipulator::handleInputEvent ( const GUI::InputEvent & event, const GUI::View & view )

overridevirtual

This function is called by sources of input events in order to dispatch them to the handlers.

In case there are more than one InputEventHandlers dispatchers are intended call this function consecutively until the first handler indicates to stop by returning a result where EventResult::stopPropagation() is true.

Implements ImFusion::GUI::ViewObject::EventHandler.
