你如何使用 MFC CScrollbar 控件? [英] How do you use MFC CScrollbar controls?

问题描述

我已将水平 CScrollBar 控件拖放到对话框中.你到底是怎么用它的??

I have dropped a horizontal CScrollBar control onto a dialog box. How on earth do you use it??

我尝试将手柄向右移动，但它直接跳回左侧.所以我想我可能需要设置范围.我调用了 SetScrollRange(0, 100)，它仍然做同样的事情.我在谷歌上找不到任何有帮助的例子——所有滚动条引用似乎都是指使用视图类等，但这不是我想做的.

I tried moving the grip to the right and it jumped straight back to the left.. so I figured I may need to set the range. I called SetScrollRange( 0, 100 ) and it still does the same thing. I can't find any examples on Google that help - all scrollbar references seem to refer to using the view class etc etc but thats not what I want to do.

我想要做的就是移动手柄并收到一条包含一些描述的通知消息，我该怎么做(请)?

All I want to do is move the grip and get a notification message back of some description, how do I do that (please)?

推荐答案

想知道的，需要自己处理WM_HSCROLL/WM_VSCROLL消息..收到SB_THUMBPOSITION消息时自己调用SetScrollPos().

For anybody that wants to know, you need to handle the WM_HSCROLL/WM_VSCROLL messages yourself.. and call SetScrollPos() yourself when receiving the SB_THUMBPOSITION messages.
