C++ (Cpp) UpdateScreenAngle Examples

Example #1

File: GlueMapWindow.cpp Project: CnZoom/XcSoarPull

void
GlueMapWindow::QuickRedraw()
{
  UpdateScreenAngle();
  UpdateProjection();
  UpdateMapScale();
  UpdateScreenBounds();

#ifndef ENABLE_OPENGL
  /* update the Projection */

  ++ui_generation;

  /* quickly stretch the existing buffer into the window */

  scale_buffer = 2;
#endif

  Invalidate();

#ifndef ENABLE_OPENGL
  /* we suppose that the operation will need a full redraw later, so
     trigger that now */
  draw_thread->TriggerRedraw();
#endif
}

Example #2

File: GlueMapWindow.cpp Project: macsux/XCSoar

void
GlueMapWindow::FullRedraw()
{
  UpdateDisplayMode();
  UpdateScreenAngle();
  UpdateProjection();
  UpdateMapScale();

#ifdef ENABLE_OPENGL
  invalidate();
#else
  draw_thread->TriggerRedraw();
#endif
}
