我的MFC应用程序中有CListCtrl
。当我从服务器收到一些通知时,需要更新列表。当列表上的操作较少时,通知较少时,更新列表的效果非常好。但是在负载很重的情况下,列表控制反过来应用程序会冻结。
我知道在批量更新的情况下更新单独线程中的UI项目,但在这种情况下,我有任何顺序和任何卷中的通知,我需要以我的主线程的方式处理没有被阻止。
如果有人在遇到此问题之前请为此案例提出建议。
答案 0 :(得分:1)
您可以将所有更新放入队列中。然后在OnIdle函数中从队列到控件执行有限数量的更新。当GUI消息队列为空时,将调用OnIdle。它可以做20个更新,然后返回。主线程将处理任何GUI输入,完成后它将再次调用OnIdle。通过这种方式,您可以在保持GUI活动的同时延迟并展开更新。
答案 1 :(得分:0)
我有类似的情况并使用Timer解决了它。只有当计时器勾选时,才能更新ListCtrl。
