Public Methods   Animator () virtual  ~Animator () virtual void  load_key (const char *key, const char *value) int  setAnimationMin (double)   Sets the value that the animation begins at and returns to after the end of a loop. int  setAnimationMax (double)   Sets the maximum value the animation will reach before ending. int  setAnimationStep (double)   Sets the step of each animation. int  setAnimationSpeed (int)   Sets the speed between each frame in the animation in milliseconds ( 1000 ms = 1 sec ). double  getAnimationMin () const   Returns the value that the animation begins at and returns to after the end of a loop. double  getAnimationMax () const   Returns the maximum value the animation will reach before ending. double  getAnimationStep () const   Returns the step of each animation. int  getAnimationSpeed () const   Returns the speed of the graph in milliseconds. void  setAnimationFrame (double n)   Sets the value of the the animator to the given number. double  animatorValue () const   Subclasses should use this function to get the current stage of the animation in order to produce the animation. void  play ()   Begins to play the animation and will loop until pause() or stop() is called. void  stop ()   Stops a playing animation and resets the current animator value to the minimum. void  pause ()   Stops a playing animation, but unlike stop(), the current animator value remains what is was. void  saveAsMovie ()   Save the complete animation as a movie. bool  displayAnimatorValue () void  setDisplayAnimatorValue (bool b) Protected Methods virtual void  nextFrameReady ()=0   Classes that implement this class need to implement this function. void  nextFrame ()   This function should be called after every timer timeout. void  initializeAnimator (QObject *)   Call this function before using the animation interface. bool  isSaving () const Detailed Description This class provides an interface for animating a graph. Author: Fungmeista Note: Because the QTimer class uses signals/slots, subclasses currently must include a slotNextFrame() slot that calls this class's nextFrame() function. The Animator class itself cannot contain signals/slots, because this would require it to be a QObject subclass. If it were a QObject subclass, QObject subclasses would not be able to inherit it ( Multiple inheritance clashes ). This is an instance when using callbacks would be better than signals/slots... anyways, I'm looking for other workarounds :-) Also, don't forget to call initialize() before using this class. Definition at line 37 of file animator.h. Member Function Documentation void Animator::initializeAnimator (  QObject *    )  [protected]   Call this function before using the animation interface. It should be given a pointer to this class's subclass. This function connects the timeout() signal of the QTimer class used to the slotNextFrame() slot of the given class. Definition at line 39 of file animator.cpp. virtual void Animator::nextFrameReady (    )  [protected, pure virtual]   Classes that implement this class need to implement this function. This function is called everytime the next frame is ready and the subclass should implement an animation with it Implemented in ExpressionGraph, and GLExpressionGraph. Referenced by nextFrame(), setAnimationFrame(), and stop(). void Animator::pause (    )    Stops a playing animation, but unlike stop(), the current animator value remains what is was. Calling play() will continue the animation from where it left off. Definition at line 84 of file animator.cpp. References play(). void Animator::saveAsMovie (    )    Save the complete animation as a movie.
