qt做的分页控件
如何使用
创建
Pagination必须基于一个QWidget创建否则会引发错误。
Pagination* pa new Pagination(QWidget*);设置总页数
Pagination需要设置一个总的页数来初始化页码。
pa-SetTotalItem(count);设置可选的每页数量
可以通过传给Pagination一个整形数组来设置每页显示的条目数。
int args[4] {1, 100, 200, 300};
pa-SetItemPerPage(args, 4);刷新配置参数
当上面参数设置完成后需要调用一次Refresh来刷新配置。
pa-Refresh();获取当前页数的变化
当Pagination当前的页码发生变化时会产生一个PageChanged信号原型如下
void PageChanged(int nPage);其中nPage代表要跳转的页数。
获取每页条目数的变化
当Pagination的每页数量发生变化时会产生一个NumberPerPageChanged信号原型如下
void NumberPerPageChanged(int nCount);其中nCount表示最新的每页条目数量。 #include pagination.h
