C++ QStackedWidget::setFont方法代码示例

/*
 *  Exposure bracketing page.
 *
 *  Purpose:
 *  1. selecting best shot, and
 *  2. increase dynamic range (HDR).
 *
 *  For both of these purposes, it is best to maintain a fixed aperture,
 *  focal distance, focal length, ISO setting, subject distance, and white
 *  balance. That means Manual mode or Av mode, and no auto ISO, no auto
 *  white balance, no auto focus (or turn off auto focus once focus has
 *  been achieved when setting up the shot) and use a tripod if available
 *  (turn off image stabilization).
 *
 *  For purpose 2, want to take the frames as quickly as the exposure can
 *  be adjusted between images (to minimize movement of the subject).
 *  For static subjects, the exposure is usually adjusted by altering the
 *  shutter speed. For dynamic subjects, the exposure can be adjusted by
 *  altering the ISO (not yet implemented, but if shooting RAW this can
 *  be done in post-processing).
