如何使用MFC CScrollbar控件?
我已将水平 CScrollBar 控件放到对话框中。你到底怎么用它?
我尝试将手柄移至右侧,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 Google 上找不到任何有帮助的示例 - 所有滚动条引用似乎都指使用视图类等,但这不是我想要做的。
我想做的就是移动手柄并收到一些描述的通知消息,我该怎么做(请问)?
I have dropped a horizontal CScrollBar control onto a dialog box. How on earth do you use it??
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.
All I want to do is move the grip and get a notification message back of some description, how do I do that (please)?

对于任何想知道的人,您需要自己处理 WM_HSCROLL/WM_VSCROLL 消息..并在收到 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.
