问题 I'm implementing a TextFormField with the maxLines attribute set to 3. How can I make the TextFormField scroll down once the user starts with his fourth line? At the moment the cursor is just not visible anymore until the user scrolls down by hand. Is there a way to do this automatically?

问题 I'm trying to do something very simple: I have two buffers in Vim, one with source code (B1), another one with a text file a.txt (B2). The source code in B1 is run with a custom shortcut in Vim, filling a.txt with text. I want Vim to automatically scroll B2 every time it updates, even if my cursor is in B1.

问题 Thank you for looking, I am creating a chat application. It works for the most part. The only thing I have a problem with is the scrolling.

So I think best way is to auto scroll down to the bottom as soon as the view is updated. Is there an easy way to do that? like in layout maybe? Thanks again

问题 Using VS2010 and .NET 4.0 with C# and WinForms: I always want a Vertical Scrollbar to show for my panel as a disabled scrollbar (when it's not needed, and a enabled one when it can be used. So it's like a hybrid AutoScroll. I've tried using VScrollBars but I can't figure out where to place them to make this work. Essentially I've got a user control that acts as a "Document" of controls, its size changes so when using auto-scroll it works perfectly. The scrollbar appears when the usercontrol

问题 I am using RichTextBox control for displaying application logs. I am updating control once a second with a few calls of RichTextBox::AppendText method.

I have tried following solution to my problem: int pos = tb_logs.SelectionStart; tb_logs.AppendText("log message"); tb_logs.SelectionStart = pos; This does not go
