Member Function Documentation

void PG_ColorSelector::PG_ColorBox::eventBlit (  SDL_Surface *  srf, const PG_Rect &  src, const PG_Rect &  dst )  [protected, 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_ThemeWidget. Definition at line 65 of file pgcolorselector.cpp. References PG_Widget::DrawHLine(), PG_Widget::DrawVLine(), PG_ThemeWidget::eventBlit(), PG_Point::x, and PG_Point::y.

bool PG_ColorSelector::PG_ColorBox::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_MessageObject. Definition at line 42 of file pgcolorselector.cpp. References GetBaseColor(), GetParent(), PG_Widget::ScreenToClient(), PG_MessageObject::SetCapture(), and PG_Widget::Update().

bool PG_ColorSelector::PG_ColorBox::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_MessageObject. Definition at line 55 of file pgcolorselector.cpp. References PG_MessageObject::ReleaseCapture().

bool PG_ColorSelector::PG_ColorBox::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 14 of file pgcolorselector.cpp. References GetBaseColor(), GetParent(), PG_Rect::my_height, PG_Rect::my_width, PG_Widget::ScreenToClient(), PG_Widget::Update(), PG_Point::x, and PG_Point::y.

PG_ColorSelector* PG_ColorSelector::PG_ColorBox::GetParent (   )  [inline]

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 15 of file pgcolorselector.h. References PG_Widget::GetParent(). Referenced by eventMouseButtonDown(), and eventMouseMotion().
