How to autoscroll to the end of RichEdit?

问题

I never needed to use the TRichEdit before, always used TMemo.

I'd like RichEdit autoscrolling to the end when I add text like TMemo. See how it looks after you add some data:

As you can see, the scroll bar remains at the top, but I'd like it stayed at the bottom as I added text.

I've 'googled' for solutions but I couldn't find a good and reliable one.

回答1:

Try this code

RichEdit1.SetFocus;
RichEdit1.SelStart := RichEdit1.GetTextLen;
RichEdit1.Perform(EM_SCROLLCARET, 0, 0);

Here is much easier and fast solution:

In OnChange event handler just:

SendMessage(RichEdit1.handle, WM_VSCROLL, SB_BOTTOM, 0);

回答3:

In short, you need to place the cursor at the end, or send code to scroll down.

Have you tried

Richedit1.SelStart :=RichEdit1.GetTextLength();
SendMessage(RichEdit1.handle, EM_SCROLLCARET,0,0);
