Member Function Documentation

bool PG_ScrollBar::ScrollButton::eventMouseButtonDown (  const SDL_MouseButtonEvent *  button  )  [protected, virtual]

Overridable Eventhandler for a SDL_MouseButtonEvent message. This handler is called when a mouse button is pressed. The default implementation returns 'false' which indicates that this message is not processed by this object. Parameters: button  SDL_MouseButtonEvent message Returns: Notifies the message pump if this message is processed by this object or it should be routed to the next message receiver. Reimplemented from PG_Button. Definition at line 333 of file pgscrollbar.cpp. References PG_Button::eventMouseButtonDown(), PG_Application::GetEventSupplier(), and PG_Widget::ScreenToClient().

bool PG_ScrollBar::ScrollButton::eventMouseButtonUp (  const SDL_MouseButtonEvent *  button  )  [protected, virtual]

Overridable Eventhandler for a SDL_MouseButtonEvent message. This handler is called when a mouse button is released. The default implementation returns 'false' which indicates that this message is not processed by this object. Parameters: button  SDL_MouseButtonEvent message Returns: Notifies the message pump if this message is processed by this object or it should be routed to the next message receiver. Reimplemented from PG_Button. Definition at line 406 of file pgscrollbar.cpp. References PG_Button::eventMouseButtonUp(), and GetParent().

bool PG_ScrollBar::ScrollButton::eventMouseMotion (  const SDL_MouseMotionEvent *  motion  )  [protected, virtual]

Overridable Eventhandler for a SDL_MouseMotionEvent message. This handler is called when mouse movement is detected. The default implementation returns 'false' which indicates that this message is not processed by this object. Parameters: motion  SDL_MouseMotionEvent message Returns: Notifies the message pump if this message is processed by this object or it should be routed to the next message receiver. Reimplemented from PG_MessageObject. Definition at line 274 of file pgscrollbar.cpp. References GetParent(), GetPosFromPoint(), PG_Button::GetPressed(), PG_Widget::MoveWidget(), PG_Rect::my_height, PG_Rect::my_width, PG_ScrollBar::position, PG_ScrollBar::VERTICAL, PG_Point::x, and PG_Point::y.

PG_ScrollBar * PG_ScrollBar::ScrollButton::GetParent (   )  [protected]

Get the parentwidget of a widget. Returns: a pointer to the parentwidget or NULL if there is no parentwidget Reimplemented from PG_Widget. Definition at line 345 of file pgscrollbar.cpp. References PG_Widget::GetParent(). Referenced by eventMouseButtonUp(), eventMouseMotion(), and GetPosFromPoint().
