滚动RichEdit没有它的焦点 [英] Scrolling RichEdit without it having focus

问题描述

在添加行后，我需要滚动一个RichEdit到最后。我有这个RichEdit在一个单独的形式，我不想得到焦点。我经常提出解决方案：

  RichEdit.Lines.Add（someText）; 
 RichEdit.SelStart：= RichEdit.GetTextLen; 
 SendMessage（RichEdit.handle，EM_SCROLLCARET，0，0）; 
  

但这对我来说不起作用。然而，当我使用 RichEdit.SetFocus; 调用 SendMessage 之前，我集中了RichEdit，它的工作原理很好。但是，这个应用程序遗失了我的其他需求。

我正在使用XE2。谢谢

解决方案

这是我做的：

  SendMessage（RichEdit.Handle，WM_VSCROLL，SB_BOTTOM，0）; 
  

I need to scroll a RichEdit to the very end after a line is added. I have this RichEdit in a separate form, that I don't want to get focus at all. I tried often suggested solution:

RichEdit.Lines.Add(someText);
RichEdit.SelStart:=RichEdit.GetTextLen;
SendMessage(RichEdit.handle, EM_SCROLLCARET, 0, 0);

But this doesn't work for me. However, when I focus the RichEdit before calling the SendMessage using RichEdit.SetFocus; it works just fine. That, however, ruins my other needs for the app.

I'm using XE2. Thanks

解决方案

This is what I do:

SendMessage(RichEdit.Handle, WM_VSCROLL, SB_BOTTOM, 0);
