I need to implement a way so that the page should auto-scroll down to the Hash i.e. api-doc but somehow it's not auto-scrolling on page load (very first time). I tried a workaround which is like this componentDidUpdate(){ let id = this.props.history.location.hash.replace("#", ""); let element = document

Automatically scroll multiline TextFormField when it extends the maxLines attribute

廉价感情. 提交于 2020-04-10 09:33:12
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? This behaviour is actually featured in the flutter_gallery app in the 'Text fields' example. Just type a long text to the 'Live story' input until it reaches the fourth line. The important parts of my code

Vim automatic scroll buffer

China☆狼群 提交于 2020-01-15 08:09:31
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. So, I just want that the buffer B2 to behave the way tail -f does. Doing this with ConqueTerm is not an option, since buffer B2 can be a preview buffer from other plugin. 回答1: In general,

Android: auto scrolling down the EditTextView for chat apps

醉酒当歌 提交于 2020-01-13 11:45:52
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. I use EditText to publish the new message from the server. by method msg = msg + "\n" + newMsg EditText.setText(msg) I need to make the new text that is under the old text visible as soon as it comes. 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

How to force vertical scrollbar always be visible from AutoScroll in WinForms?

对着背影说爱祢 提交于 2020-01-10 03:47:07
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

Disabling RichTextBox autoscroll

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. What is really annoying for me is that cursor keeps scrolling to the last line of text. Its very uncomfortable in situation when user needs to analyze logs that are at the beginning. 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
