void GraphWidget::eventBlit (  SDL_Surface *  surface, const PG_Rect &  src, const PG_Rect &  dst )  [inline, virtual]

overridable eventhandler to blit the widget contents to the screen Parameters: surface  pointer to SDL_Surface to be blitted src  source rectangle (client coordinates) dst  destination rectangle (screen coordinates) Override this eventhandler to perform custom blitting behaviour (without drawing onto the widget surface). Reimplemented from PG_Widget. Definition at line 1384 of file cargodialog.cpp. References PG_Widget::ClientToScreen(), getBarHeight(), getPoint(), PG_Application::GetScreen(), PG_Rect::Height(), mapColor(), PG_Rect::Width(), Surface::Wrap(), PG_Point::x, xrange, PG_Point::y, and yrange.

bool GraphWidget::eventMouseButtonDown (  const SDL_MouseButtonEvent *  button  )  [inline, 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_MessageObject. Definition at line 1335 of file cargodialog.cpp. References click(), PG_Widget::ScreenToClient(), and PG_Point::x.

bool GraphWidget::eventMouseMotion (  const SDL_MouseMotionEvent *  motion  )  [inline, 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 1323 of file cargodialog.cpp. References click(), PG_Widget::ScreenToClient(), and PG_Point::x.

virtual int GraphWidget::getBarHeight (  int  bar  )  [inline, protected, virtual]

Reimplemented in MiningGraph. Definition at line 1320 of file cargodialog.cpp. Referenced by eventBlit().

virtual int GraphWidget::getPoint (  int  curve, int  x )  [inline, protected, virtual]

Definition at line 1347 of file cargodialog.cpp. References PG_Application::GetScreen(), PG_Widget::GetTransparency(), and PG_Color::MapRGBA(). Referenced by eventBlit().

void GraphWidget::setRange (  int  x, int  y )  [inline]

Definition at line 1355 of file cargodialog.cpp. References max(), xrange, and yrange. Referenced by MiningGraph::MiningGraph(), and ResearchGraph::ResearchGraph().
