• IE Problem: Jagged Scrolling and Dragging Inside Large Viewport

  - by br4inwash3r

  My site is a single page website with a very large "canvas" size. and to navigate around the site i'm using jquery scrollTo and jquery Dragscrollable plugin. in IE 7 & 8 the scrolling/dragging movement is very jagged. at first i thought it was my script or some other plugin that's causing this. but after i stripped down everything it's still the same. i've tried a few tips i've found around here. but none is really working for me. i know i should be asking this question to the plugin developers. i did.. i just thought maybe you guys have some other solution for this issue. here's the URL to the demo site: http://satuhati.com/bare/template/ really appreciate any help u can give :) thx..

• iOS CollectionView with horizontal paging instead of vertical scrolling

  - by Nico Griffioen

  I'm working on a project for a client. It's an iPad pdf reader. The client wants a collection view, but instead of scrolling vertically, he wants it to use a page control. It's pretty hard to explain, but what I basically want is all the PDFs on the device in a grid, like on the iBooks app. When that grid overflows, I want to use a page control to display the extra elements on a second page (like in the weather app). My thoughts on this were: - Create a page control with one page. - On that page, create a UICollectionView. - If the number of elements is greater than 9 add a page to the page control and add another UICollectionView, until there are enough pages to display all elements. However, this seems horribly inefficient, so my question is if there's a better way to do this.

• Displaying/scrolling through heaps of pictures in the browser

  - by user347256

  I want to be able to browse through heaps of images in the browser, fast. THe easy way (just load 2000 images and scroll) slows down the scrolling a lot, assumedly because there's too much images to be kept in memory. I'd love to hear thoughts on strategies to be able to quickly scroll through 10000s of images (as if you were on your desktop) in the browser. What would expected bottlenecks be? How to address them? How to fake things so that the user experience is still good? Examples in the wild?

• ScrollViewr around expanders not scrolling automatically when expander is expanded - silverlight 3

  - by Sil

  I have several expanders inside a ScrollViewer in a fixed sized ChildWindow. The problem is when each expander expanded,the scroll will not scrolling down automatically and as a result,some of the items in the bottom will get hidden and we have to manually scroll down to see them. I saw some posts like the following link but I guess my situation is different because the children inside expanders will not get focused and I need to do something when the expander is expanded. http://stackoverflow.com/questions/1225318/how-can-i-make-the-silverlight-scrollviewer-scroll-to-show-a-child-control-with-f I am just wondering if there is a slution for that- and also would like to know if this problem is solved in silverlight 4. Thanks in advance for any help. Sil.

• 2D Engine scrolling on OpenGL via hardware?

  - by drudru

  hi, I'm using OpenGL as the bottom end for a 2D tiling engine. When everything is 2D, it is simple to optimize certain issues. For example, scrolling. If I know a certain section of the screen needs to scroll off the bottom, then I can just blit over that portion. I'm evening moving more than 1 pixel at a time. Without explicit hardware support (think old nintendo hw), this requires a lot of pixel writes. An on chip bitblt would be the next best thing. Essentially, I'm looking at how I can optimize my GL calls to use VRAM texture renders as efficient hardware blits. Is it possible to have GL scroll the framebuffer, or should I just resign myself to double-buffering and re-rendering an entire scene for each frame? Thx

• Prevent auto scrolling when clicking tab anchor

  - by JohnCrossy

  On my page I have some tabs that I've added some javascript so when they're clicked the page loads the tab's anchor URL instead of simply changing the view with AJAX, but I now want to stop the browser from auto scrolling to the anchor location. Having done some research, I'm pretty sure I just need to add a couple of lines so that when clicked it returns false or prevents default but, being a noob, I've no idea where to put them!?! I know it's cheeky, but if any answers could include the full script (ie. the below) with the solution, that way I'll understand better and hopefully learn some valuable lessons also :) Here's the code I'm using: jQuery( function() { jQuery('.ui-tabs').bind( 'tabsselect', function( e, ui ) { window.location.hash = ui.tab.hash }); });

• Length of text that can just fit into one screen without scrolling

  - by KailZhang

  I find some iphone book apps have such feature: One screen one page of text without scrolling. The text can just fit into the whole screen with linebreaks and indentations. I'm curious of how to implement this. How could I decide the length of text that just fit into the screen. And also, given the whole text, I can calculate out the number of pages. If this is not possible to be done on iPhone(runtime?), then is it possible to process the text before storing it in app? I mean I calculate how many pages I need(how to split the raw text), probably how many lines per page.

• Enable vertical scrolling on textarea

  - by Hozefa

  I have a textarea that I want to enable vertical scrolling. When I exceed the height of the textarea, it increases in size. The scroll bar does not appear. I want that a vertical scroll bar appears and the users are not able to resize the text area as well. I searched online and tried solutions posted, but none seem to work. Demo: http://jsfiddle.net/hozefa/8fv6e/ CSS: #imageURLId{ font-size: 14px; font-weight: normal; resize: none; overflow-y: scroll; } HTML: <label for="aboutDescription" id="aboutHeading">About</label> <textarea rows="15" cols="50" id="aboutDescription" style="resize: none;"></textarea> <a id="imageURLId" target="_blank">Go to HomePage</a>

• WPF DataGrid does not scoll on drag

  - by Greg R

  I have a strange problem with a WPF DataGrid from WPF Toolkit. The scrollbars appear correctly when the number of rows grows, and the scrolling works when you press up or down arrows on the scrollbar. The problem comes in when I try to drag the scrollbar on the datagrid. My page has a scroll viewer around it. When I click and drag the scrollbar on the grid, it scrolls the page scroller instead. If the scrollbar does not apear on the page, there grid still does not scroll. Is there a workaround for this??? Would really appreciate some help with this issue! For example, in this case if the page is < 280, it scrolls on drag. But drag scrolling does not work on the grid. <ScrollViewer ScrollViewer.IsDeferredScrollingEnabled="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" > <DockPanel> <dg:DataGrid HorizontalScrollBarVisibility="Auto" SelectionMode="Single" CanUserAddRows="False" CanUserDeleteRows="False" CanUserResizeColumns="False" CanUserSortColumns="False" AutoGenerateColumns="False" RowHeaderWidth="17" ItemsSource="{Binding Path=OrderSearchVm}" IsReadOnly="True" MaxHeight="280" DockPanel.Dock="Top"> <dg:DataGrid.Columns> <dg:DataGridTextColumn Width="75" Header="Date" Binding="{Binding Path=OrderDate}" > <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Type" Binding="{Binding Path=OrderType}" Width="45"/> <dg:DataGridTextColumn Header="Shipping Name" Binding="{Binding Path=ShipToName}" Width="115"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="Shipping Address " Binding="{Binding Path=ShipToAddress}" Width="160"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> <dg:DataGridTextColumn Header="E-Mail" Binding="{Binding Path=Email}" Width="140"> <dg:DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <Setter Property="TextWrapping" Value="Wrap" /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> </dg:DataGrid.Columns> </dg:DataGrid> </DockPanel> </ScrollViewer>

• scrolling lags in emacs 23.2 with GTK

  - by mefiX

  Hey there, I am using emacs 23.2 with the GTK toolkit. I built emacs from source using the following configure-params: ./configure --prefix=/usr --without-makeinfo --without-sound Which builds emacs with the following configuration: Where should the build process find the source code? /home/****/incoming/emacs-23.2 What operating system and machine description files should Emacs use? `s/gnu-linux.h' and `m/intel386.h' What compiler should emacs be built with? gcc -g -O2 -Wdeclaration-after-statement -Wno-pointer-sign Should Emacs use the GNU version of malloc? yes (Using Doug Lea's new malloc from the GNU C Library.)

• Coda-Slider Problem in ie7, need to remove horizontal scrollbar

  - by Mike

  Hello, I am having a big issue with coda-slider and ie7. The horizontal scrollbar is unwanted and I cannot figure out how to remove it. Since coda-slider works as one long scrolling div, I could see why this is happening, however, in all other broswers, including ie8, there is no horizonal scroll. Looking through the web there are alot of sites saying "overflow-x:hidden" will work on the body selector in css, however this has not solved the issue. the site is at http://www.clearcreativegroup.com/clear3/index.html Any help would be greatly appreciated.

• Horizontal scroll winforms listview

  - by tempy

  Anyone know if its possible to enable horizontal scrolling ONLY in a windows forms listview (viewmode set to large icons). What I want to do is make a listview whose height is sufficient to only show one row of icons, and I don't want to have multiple rows. Just one very long row that a user would have to scroll horizontally to get to out-of-range icons. If I make the listview scrollable then it automatically makes multiple rows and puts in a vertical scrollbar, which I don't want. Thanks in advance!

• Android Layout: Display as much ImageViews as possible without scrolling

  - by Toni4780

  I am working on an app which should display several same size images on the screen. But it should only display only so much images as possible without offering scrolling. E.g. On a "big" tablet it could display 10x10 Imageviews (screen is large, so there is much space for pictures) On a "big" phone there might be enough space to display 6x6 ImageViews, so it should only display a 6x6 array of images. On a small phone there is propably only space for 4x4 ImageViews, so it should only display this. How can I make this in Android? I know about "layout-large", ... but if i make a special fixed xml-layout for a "large" device, it would not fit all devices correct. E.g. a Galaxy Nexus is a "normal" device and so is a Nexus One, but there would be at least be space for one or two more imageview rows on a Galaxy Nexus than on a Nexus One. So do I have to measure in code somehow how big the resolution is and display some TableRows accordingly? Or is there a special way how I can manage this?

• jQuery ui datepicker positioning problem when scrolling down webpage

  - by Remnant

  I have a webpage that uses multiple instances of the jQuery ui datepicker. My webpage will display ~80 records which extends beyond a single screenshot. <% foreach (var record in Model) { %> <div class="recordname"><%=record.name%></div> <%=Html.TextBox("DateTimePicker", null, new { @class = "date-pick" } )%> // <-- additional html here --> <% } %> I have set the defaults of my datepicker as follows: $(".date-pick").each(function() { $(this).datepicker({ dateFormat: 'dd M yy', showOn: 'button', buttonImage: '/Images/datepickericon.png', buttonImageOnly: true }); }); When the page first loads, if I click any datepicker icon that is visible on screen (i.e. without scrolling) then the datepicker appears as expected. However, if I scroll down the page and then click a datepicker icon, the datepicker does not appear in the screen window but is instead rendered right back near the top of the screen. Any ideas how to solve this? I am using: IE7 asp.net mvc jquery.ui.datepicker.js (UI/API/1.8/Datepicker)

• How to hide the vertical scroll bar in a .NET ListView Control in Details mode

  - by Adam Haile

  I've got a ListView control in Details mode with a single column. It's on a form that is meant to only be used with the keyboard, mostly with the up/down arrows for scrolling and enter to select. So I don't really need to have the scroll bars and would just like them to not show for a cleaner look. However, when I set the ListView.Scrollable property to false, I can still move the selected item up and down, but as soon as it moves to an item not currently in view, the list won't move to show that item. I've tried using EnsureVisible to programmatically scroll the list, but it does nothing when in this mode. Is there any way to manually move the list up and down to scroll, but without having the scrollbar present?

• iPhone: Having trouble figuring out how to scroll a UITableView with custom UITextField cells automa

  - by Gordon Fontenot

  Ok, I know this seems like a duplicate question, but don't think it is. I actually have this implemented already (thanks to this SO question), but it seems sluggish. I am willing to tweak it a bit, but I ran across a demo app by AboutObjects that seems to have exactly the right functionality with absolutely no code doing it. I have looked through their demo code dozens of times, and I can't figure out what they are doing that I am not. The code to look at is in their iPhone Development Tutorials section, and is called "Editable TableView" (2nd from the bottom). There are a couple of questions on the forums on that site asking how they got the functionality, but there is no answer (other than "It's a built in function"). Does anyone have any clue as to why their UITableView would implement the input scrolling by default (including being able to scroll the view manually when the keyboard pops up, which I cannot get to work)?

• How to get CEdit to scroll properly?

  - by CSharperWithJava

  I have a CEdit control that's used to display a diagnostics output. Sometimes the data overflows the screen size, so naturally I set the Vertical Scroll property to true (MFC dialog editor). But then, when I tried to scroll the text that was in the window before isn't cleared and the new text is written over it. The result is a big mess of everything I have scrolled past. I've looked for a draw background property or something similar that will erase everything in the window while scrolling (before redrawing the new data). Any suggestions?

Why is this the case?

• How to retarget the scroll wheel in VB.Net?

  - by Orborde

  I have a form in VB.Net with Autoscroll enabled and several ComboBoxes within it. When I click on a ComboBox, I can use the mouse wheel to scroll through options, but I cannot deselect the ComboBox (by clicking off it on a blank portion of the parent form) in order to return to scrolling the parent form. This makes navigation in the form annoying, as I instinctively click off the control and flip the scroll wheel, causing the ComboBox to change selections instead of moving the parent form. Is there a way to make this work in the intuitive way I expect it to, or do I have some conceptual confusion that makes this the wrong question to ask?

• jQuery: detecting reaching bottom of scroll doesn't work, only detects the top! :(

  - by Jack Webb-Heller

  Hi folks! So basically my problem is a seemingly simple one. You can see it in action at http://furnace.howcode.com (please note that data is returned via Ajax, so if nothing happens give it a few moments!). What's MEANT to happen, is in the second column when you reach the bottom of scrolling, the next 5 results are returned. But what actually happens is it only returns the 5 results when you hit the TOP of the scroll area. Try it: scroll down, nothing happens. Scroll back up to the top, the results are returned. What's going wrong? Here's my code I'm using: $('#col2').scroll(function(){ if ($('#col2').scrollTop() == $('#col2').height() - $('#col2').height()){ loadMore(); } }); loadMore(); is the function that gets the data and appends it. So what's going wrong here? Thanks for your help! Jack

• GDI fast scroll

  - by genesys

  Hi! I use GDI to create some custom textwidget. I draw directly to the screen, unbuffered. now i'd like to implement some fast scrolling, that simply pixelshifts the respective part of the framebuffer (and only redraws the newly visible lines). I noticed that for example the rich text controls does it like this. If i use some GDI drawing functions to directly draw to the framebuffer, over a rich text control, and then scroll the rich text, it will also scroll my drawing along with the text. so i assume the rich text simply pixelshifts it's part of the framebuffer. I'd like to do the same, but don't know how to do so. Can someone help? (independant of programming language)) thanks!
