一、介绍
1、The QScrollArea class provides a scrolling view onto another widget.
2、A scroll area is used to display the contents of a child widget within a frame. If the widget exceeds the size of the frame, the view can provide scroll bars so that the entire area of the child widget can be viewed.
二、示例
1、代码
//
QScrollArea *sa_div; /* 画面滑动创建 /* 滑动区域 */
sa_div = new QScrollArea(wd_preview);
sa_div->setWidget(wd_previewDiv);
sa_div->resize(wdMainWidth * 4/5, wdMainHeight);
sa_div->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff); /* 隐藏滑动条 */
sa_div->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
//
