How to increase scrollback buffer size in tmux?

How do I increase scrollback buffer size in tmux?

If I enter copy mode, the number of available scrollback lines (visible in upper right corner) is always below 2000. I tried to find a list of all tmux commands, but I can't find anything about scrollback size. For all I see the screen command for setting that option doesn't work with tmux.

Using tmux 1.8, Ubuntu 12.04 LTS, either konsole or gnome-terminal.

Maintain/Save/Restore scroll position when returning to a ListView

I have a long ListView that the user can scroll around before returning to the previous screen. When the user opens this ListView again, I want the list to be scrolled to the same point that it was previously. Any ideas on how to achieve this?

Check if a user has scrolled to the bottom

I'm making a pagination system (sort of like Facebook) where the content loads when the user scrolls to the bottom. I imagine the best way to do that is to find when the user is at the bottom of the page and run an ajax query to load more posts.

The only problem is I don't know how to check if the user has scrolled to the bottom of the page with jQuery. Any ideas?

I need to find a way to check when the user has scrolled to the bottom of the page with jQuery.

How to move screen without moving cursor in Vim?

I recently discovered Ctrl+E and Ctrl+Y shortcuts for Vim that respectively move the screen up and down with a one line step, without moving the cursor.

Do you know any command that leaves the cursor where it is but moves the screen so that the line which has the cursor becomes the first line? (having a command for the last line would be a nice bonus).

I can achieve this by manually pressing Ctrl+E (or Ctrl+Y) the proper number of times, but having a command that somehow does this directly would be nice.

Any ideas?

How do I automatically scroll to the bottom of a multiline text box?

I have a textbox with the .Multiline property set to true. At regular intervals, I am adding new lines of text to it. I would like the textbox to automatically scroll to the bottom-most entry (the newest one) whenever a new line is added. How do I accomplish this?

Prevent BODY from scrolling when a modal is opened

I want my body to stop scrolling when using the mousewheel while the Modal (from http://twitter.github.com/bootstrap) on my website (http://www.mysocialsync.com) is opened.

I've tried to call the piece of javascript below when the modal is opened but without success

$(window).scroll(function() { return false; });

AND

$(window).live('scroll', function() { return false; });

Please note our website dropped support for IE6, IE7+ needs to be compatible though.

        Random r = new Random();
        int i = r.nextInt(101);

Making a UITableView scroll when text field is selected

After a lot of trial and error, I'm giving up and asking the question. I've seen a lot of people with similar problems but can't get all the answers to work right.

I have a UITableView which is composed of custom cells. The cells are made of 5 text fields next to each other (sort of like a grid).

When I try to scroll and edit the cells at the bottom of the UITableView, I can't manage to get my cells properly positioned above the keyboard.

I have seen many answers talking about changing view sizes,etc... but none of them has worked nicely so far.

Could anybody clarify the "right" way to do this with a concrete code example?

How to scroll to specific item using jQuery?

I have a big table with vertical scroll bar. I would like to scroll to a specific line in this table using jQuery/Javascript.

Are there built-in methods to do this?

Here is a little example to play with.

div {
    width: 100px;
    height: 70px;
    border: 1px solid blue;
    overflow: auto;
}

<div>
    <table id="my_table">
        <tr id='row_1'><td>1</td></tr>
        <tr id='row_2'><td>2</td></tr>
        <tr id='row_3'><td>3</td></tr>
        <tr id='row_4'><td>4</td></tr>
        <tr id='row_5'><td>5</td></tr>
        <tr id='row_6'><td>6</td></tr>
        <tr id='row_7'><td>7</td></tr>
        <tr id='row_8'><td>8</td></tr>
        <tr id='row_9'><td>9</td></tr>
    </table>
</div>

Tricks for improving iPhone UITableView scrolling performance?

I have a uitableview that loads fairly large images in each cell and the cell heights vary depending on the size of the image. Scrolling performance is decent, but can sometimes be jerky.

I found these tips I found on the FieryRobot blog:

glassy-scrolling-with-uitableview

more-glassy-scrolling-with-uitableview

Does anyone have any tips for improving uitableview scrolling performance?

jquery-ui sortable | How to get it work on iPad/touchdevices?

How do I get the jquery-ui sortable feature working on iPad and other touch platforms? http://jqueryui.com/demos/sortable/

I tried to work with

event.preventDefault();
event.cancelBubble=true;
event.stopPropagation();

for the touchmove and the scroll event, but the only result was - as expected - that the page does not scroll any longer.

Any ideas? THX! EH!

Changing route doesn't scroll to top in the new page

I've found some undesired, at least for me, behaviour when the route changes. In the step 11 of the tutorial http://angular.github.io/angular-phonecat/step-11/app/#/phones you can see the list of phones. If you scroll to the bottom and click on one of the latest, you can see that the scroll isn't at top, instead is kind of in the middle.

I've found this in one of my apps too and I was wondering how can I get this to scroll to the top. I can do it mannually, but I think that there should be other elegant way to do this which I don't know.

So, is there an elegant way to scroll to the top when the route changes?

Thanks in advance!

How can I check if a scrollbar is visible?

Is it possible to check the overflow:auto of a div?

For example:

HTML

<div id="my_div" style="width: 100px; height:100px; overflow:auto;" class="my_class"> 
  * content
</div>

JQUERY

$('.my_class').live('hover', function (event)
{
    if (event.type == 'mouseenter')
    {
         if( ...  if scrollbar visible ? ... )
         {
            alert('true'):
         }
         else
         {
            alert('false'):
         }
    }

});

Sometimes is the content short (no scrollbar) and sometimes long (scrollbar visible).

Prevent scrolling of parent element?

I have a little "floating tool box" - a div with position:fixed; overflow:auto. Works just fine.

But when scrolling inside that box (with the mouse wheel) and reaching the bottom OR top, the parent element "takes over" the "scroll request" : The document behind the tool box scrolls.
- Which is annoying and not what the user "asked for".

I'm using jQuery and thought I could stop this behaviour with event.stoppropagation():
$("#toolBox").scroll( function(event){ event.stoppropagation() });

It does enter the function, but still, propagation happens anyway (the document scrolls)
- It's surprisingly hard to search for this topic on SO (and Google), so I have to ask:
How to prevent propagation / bubbling of the scroll-event ?

Edit:
Working solution thanks to amustill (and Brandon Aaron for the mousewheel-plugin here:
https://github.com/brandonaaron/jquery-mousewheel/raw/master/jquery.mousewheel.js

$(".ToolPage").bind('mousewheel', function(e, d)  
    var t = $(this);
    if (d > 0 && t.scrollTop() === 0) {
        e.preventDefault();
    }
    else {
        if (d < 0 && (t.scrollTop() == t.get(0).scrollHeight - t.innerHeight())) {
            e.preventDefault();
        }
    }
});
