scrollbar

问题 I have multiple Tkinter listboxes that I have scrolling together using a single scrollbar, but I'd ALSO like them to scroll together for mousewheel activity over any of the listboxes. How to do this? My current code is based on the last pattern discussed here: http://effbot.org/tkinterbook/listbox.htm It works fine when using only the scrollbar, but the listboxes scroll independently when the mousewheel is used. 回答1: Solve the problem pretty much the same way as you did to connect the two

问题 I have this HTML structure: <div id="body"> <div id="head"> <p>Dynamic height without scrollbar</p> </div> <div id="content"> <p>Dynamic height with scrollbar</p> </div> <div id="foot"> <p>Fixed height without scrollbar</p> </div> </div> I want to have the three parts inside the main part (#body) without overflow. So I need a scroll bar in the middle part. I tried this CSS: #content{ border: red solid 1px; overflow-y: auto; } And this: #content{ border: red solid 1px; overflow-y: auto; height

问题 Okay I'm using jQuery and currently getting max value of scrollbar doing this: var $body = $('body'); $body.scrollLeft(99999); // will give me the max value since I've overshot var max_value = $body.scrollLeft(); // returns 300 $('body').scrollLeft(0); When I try this: $body[0].scrollWidth I just get the actual width of the contents - 1580 I'm thinking there has to be a better way I'm forgetting. EDIT To clarify, I also tried $(window).width() and $(document).width() which gave me 1280 and

问题 I've looked through questions here and articles all over the internet, but haven't found yet solution that would satisfy my requirements. So now in 2017, is there an elegant way to have a <table> that would: be written in html+css (no js) have fixed header (not scrollable; not sticky) have scrollable <tbody> (scrollbar may be always visible) header and body would handle resizing properly and not mess alignment of the <thead> columns and the <tbody> columns would not use nested tables or

问题 Background I've made a library that shows a fast-scroller for RecyclerView (here, in case anyone wants), and I want to decide when to show and when to hide the fast-scroller. I think a nice decision would be that if there are items that aren't shown on the screen (or there are a lot of them that do not appear), after the RecyclerView finished its layout process, I would set the fast-scroller to be visible, and if all items are already shown, there is no need for it to be shown. The problem I

问题 I am using the following code which is working when the scroll bar reaches the botttom, if($(window).scrollTop() == $(document).height() - $(window).height()){ I however want that the ajax is fired when i reached 70% of the scroll not 100. 回答1: Provided your current check is firing when scrolled to the page's bottom, you can try some basic arithmetics: if ($(window).scrollTop() >= ($(document).height() - $(window).height())*0.7){ //where 0.7 corresponds to 70% --^ Make sure to add a check to

问题 I need to design this scrollbar for all my scrollpanes : With Java Swing. I am using Netbeans IDE. What is the simplest solution ? Thank you very much. Regards 回答1: You can customize the look of a Swing component by setting a custom UI . In the case of a scroll pane's scroll bar, you do scrollPane.getVerticalScrollBar().setUI(new MyScrollBarUI()); where MyScrollBarUI is derived from javax.swing.plaf.basic.BasicScrollBarUI . To do this for all scroll bars (not only in JScrollPane instances),

问题 In IE10, the scrollbar is not always there... and when it appears it comes on as an overlay... It's a cool feature but I would like to turn it off for my specific website as it is a full screen application and my logos and menus are lost behind it. IE10: CHROME: Anyone know a way of always having the scrollbar fixed in position on IE10? overflow-y:scroll doesn't seem to work! it just puts it permanently over my website. It may be bootstrap causing the issue but which part I have no idea! see
