C++ (Cpp) HandleStateChange Examples

Example #1

File: ICreature.cpp Project: Paltr/SeaBoom

 void ICreature::SetActionStateChangeHandler(const ActionStateChangedHandler& stateChangeHandler)
 {
   switch(m_ActionPrevState)
   {
     case IActionBase::State::INVALID:
     {
       break;
     }
     
     case IActionBase::State::PROCESSING:
     {
       HandleStateChange(IActionBase::State::CANCELED);
       break;
     }
     
     default:
     {
       HandleStateChange(IActionBase::State::FINISHED);
       break;
     }
   }
   
   m_ActionPrevState = IActionBase::State::PROCESSING;
   m_StateChangeHandler = stateChangeHandler;
 }

Example #2

File: Widget.cpp Project: Cruel/SFGUI

	// Do nothing if state wouldn't change.
	if( GetState() == state ) {
		return;
	}

	auto old_state = GetState();

	// Store the new state.
	m_state = state;

	auto emit_state_change = false;

	// If HandleStateChange() changed the state, do not call observer, will be
	// done from there too.
	if( GetState() != old_state ) {

		emit_state_change = true;
	}

	if( state == State::ACTIVE ) {
