示例#1

文件： GlueMapWindow.cpp 项目： 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
}
