Detailed Description

Context class for tutorial state machine.

Each state represents one panel in the tutorial Tutorial assumptions:

  1. Dealing with multiple curves is postponed until the end of the tutorial.

Member Function Documentation

void TutorialStateContext::requestDelayedStateTransition ( TutorialState  tutorialState)

Request a transition to the specified state from the current state.

A timer is used. This assumes TutorialStateContext is NOT on the stack - probably since an external event (mouse click, ...) resulted in a callback to the current state

Definition at line 86 of file TutorialStateContext.cpp.

87 {
88  LOG4CPP_INFO_S ((*mainCat)) << "TutorialStateContext::requestDelayedStateTransition";

90  m_requestedState = tutorialState;
91 
92  m_timer->start ();
93 }
#define LOG4CPP_INFO_S(logger)

void TutorialStateContext::requestImmediateStateTransition ( TutorialState  tutorialState)

Request a transition to the specified state from the current state.

The transition is delayed until the current state is off the stack to prevent stack corruption errors. This assumes TutorialStateContext is on the stack to finish the transition after execution returns from the state

Definition at line 95 of file TutorialStateContext.cpp.

96 {
97  LOG4CPP_INFO_S ((*mainCat)) << "TutorialStateContext::requestImmediateStateTransition";

TutorialDlg & TutorialStateContext::tutorialDlg ( )

Access to tutorial dialogs and its scene.
