词霸的关于Form上的制作人员列表怎样做的？(5分)

如题，是不是用timer刷新？嘿嘿，请大家帮忙

可以用TIMER 控件来实现！
当然做起来不会很难！
自己做做吧！

有现成的控件scrolltext
或在rxlib里有。

把全部信息放在一个Panel上，
然后在Timer里定时向上滚:
begin
...
with Paneldo
begin
//向上滚动
Top:=Top-5;
//滚到看不见
if Top+Height<-10 then
//再重新开始
Top:=0;
end;
...
end;

如此而已

对了, 以前有过一个问题memo构件向上逐步滚动, 没有答案, 谁能解答, 有分

蚯蚓的方法是可以的
我自己做了一个控件，大家看看。

如果要平滑而没有闪烁，就要对ScrollBox编程实现

cytown:
memo中内容滚动的问题在漳龙论坛上讨论过，
你可以问问cAkk知不知道

找到了，
Win32 API:
----------------------------
<B>EM_Scroll</B>:
wParam = (WPARAM) (INT) nScroll;
lParam = 0;
wParam取值及含义：
<B>SB_LineDown</B>:下滚一行
<B>SB_LineUp</B>:上滚一行
<B>SB_PageDown</B>:下翻一页
<B>SB_PageUp</B>:上翻一页
----------------------------
<B>EM_ScrollCaret</B>:
将光标所在位置滚动到可见区域
wParam = 0;
lParam = 0;
先用<B>EM_SetSel消息</B>或<B>SetSel方法</B>设置光标位置

谢谢各位帮忙，分少别见怪！

很明显，XDict中用的定时器滚动是ScrollBox。

时间太久，强制结束。 wjiachun
