• How to change ScrollView's position after touch?

  - by Matt

  I'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp. I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list? Thanks!

• Android 2.1 address bar causes change in viewport dimensions

  - by davehumyo

  Hi, I have a page that has a 100% width and height div in it (all surrounding elements are sized accordingly so that it does actually achieve 100% width and height). Below that div I have a second div with a fixed height. In mobile safari and blackberry everything is fine, when the page loads the dimensions are applied correctly (the top div filling the viewport) and the user can scroll down to reveal the second div. Android 2.1 also applies the dimensions correctly, but with an added quirk; when the user scrolls down and removes the address bar from the page, the dimensions of the div are recalculated to fill the viewport, causing the content to jump. Ideally I would like the dimensions of the div to remain static when the page is scrolled, but remain 100% so that it will fill the viewport regardless of device size or orientation. Does anyone know of any way to disable this recalculation? Thanks for any help you can provide.

• mootools 1.1.1 scrollto element with class name ... anything like jquery?

  - by dtour

  I get the impression mootools will do this, but in a roundabout way. I am working with livevalidation script. What I want to achieve is when the from runs and errors are generated then the page will scroll to the first error found. This will be outputted as: <span class=" LV_validation_message LV_invalid">Can't be empty!</span> with jquery I could do the following: $.scrollTo($('span.LV_invalid:1')); I get the feeling in mootools I have to first find the position of the first span with class LV_invalid then pass this to the scrollTo function or is there a much simpler solution?

• iphone dev - how to catch exception 'NSRangeException'

  - by Brian

  In my app I try to scroll a UITableView to the top once after I updated the content of the table. However, under some circumstance, my table is EMPTY. So I got the following exception: Terminating app due to uncaught exception 'NSRangeException', reason: '-[UITableView scrollToRowAtIndexPath:atScrollPosition:animated:]: row (0) beyond bounds (0) for section (0).' how can I catch this exception? I tried NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; if (indexPath != nil) { [EventTable scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES]; } but it doesn't catch the exception because indexPath is not nil.

• HTML table with fixed cells size

  - by misha-moroshko

  I have an HTML table which has equally divided rows and columns. I would like each cell to be of a fixed size, say 40px width and 30px height. When I change the size of the browser window, the cells size changes also. How can I prevent it ? I would expect to see the scroll bars if browser's window become too small. Is that right to set the height and the width of the cell in pixels ? Thanks !

• jQuery colorbox plugin isn't loading inline content

  - by Summer

  Hi, I'm trying to use the jQuery colorbox plugin to show a little warning when a warning icon is clicked. Check out the problem: - Go to http://dev.imagineelection.com/browse/zip/10011 - Click on one of the warning icons (scroll down to see one). See how the colorbox that pops up is empty? I've tried to isolate the problem: - If you click "View Source" -- the div id="address-alert" is in there - If you click "View Generated Source" (for example, with Firefox Web Developer plugin) -- the div id="address-alert" has been taken out, but it has not been replaced inside the new div id="cboxCurrent" that colorbox has put at the top of the page The jQuery call I'm doing is: if (jQuery().colorbox) { $(".warning-class").colorbox({width:"50%", inline:true, href:"#address-alert"}); } What is going on? Why won't the inline content work?

• Cell Dequeue problem when table inside another table's cell content view

  - by Shailesh Kanzariya

  I am using two table views (Main Table and Sub Table), one table inside other's cell. I am adding Sub Table in Main Table's cell content view. I am also using different Cell Identifier for both table cells. Now, issue is : When - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath is called, very first time cell of Main Table is generated and when I scroll up/down they all are just dequeued, so it is expected and standard behavior and working fine. But, cell of Sub Table is getting created/allocated every time. It is not dequeued as it should be. I guess, its happening because Sub Table is part of Main Table's Cell Content view. But not sure and don't know how to resolve it. Can somebody help me to find the solution?

• Create custom launchers in GNOME 3

  - by hochl

  I'm using Debian testing, and I have been switched to GNOME 3 by the Debian update yesterday. I'm not very comfortable with the UI. I wanted to customize everything like I had it with GNOME 2, but I simply couldn't find any way to change preferences like I'm used to. I've digged some, but all answers I could find did not help me achieve my goals. So please, if anyone knows the solution to this I'd be thankful: 1) I want several launchers that launch terminals, with different arguments and different coloring/title. I have searched everything and there seems to be no menu, no right-click, nothing which is standard in any UI I know. How can I create several launchers in this bar on the left side that launch the same application, just with different parameters? With GNOME 2 this was a piece of cake. 2) I want to switch between different terminals using ALT-TAB. Right now, I'm always just getting to the same, already-opened terminal. When I open two terminals by simply creating the second one by issuing xterm &, I still get one Terminal entry with ALT-TAB, and I have to navigate with cursor keys or mouse wheel to select one of the two xterminals. Instead, I want to open a new terminal when I click the quick launch terminal icon from the bar on the left side of the screen and navigate through them like on KDE/GNOME 2/Windows/any reasonable UI. Can this be done? 3) Is there a trick to make bluetooth devices work like on GNOME 2? Right now, my BT keyboard won't pair anymore, which, as you can imagine, makes me pretty angry. and, if anything fails: 4) How can I switch back to GNOME 2 again? :-) Honestly, who did design this? What were they smoking? I feel like I'm not allowed to do anything except start one of any application that has an icon and just with the default parameters. That can't be true, right? I feel massively restrained by this stuff :(

• How to make some simple GUI controls?

  - by daniels

  I need to make a DirectX or OpenGL app and i will need a custom GUI for that. I think a button, a input text box, a list box (that will need a scroll bar as there will be more items that can fit on the screen) and a slider control will be enough. I know about CeGUI framework but i just don't like it, way too many XML files for my taste. My question is where should i start in learning how to do this custom GUI controls, are there any tutorial available or any material that could get me started? I haven't done a GUI contol myself before.

• Python doctests / sphinx : style guide, how to use those and have a readable code ?

  - by Sébastien Piquemal

  Hi ! I love doctests, it is the only testing framwork I use, because it is so quick to write, and because used with sphinx it makes such great documentations with almost no effort... However, very often, I end-up doing things like this : """ Descriptions ============= bla bla bla ... >>> test 1 bla bla bla + tests tests tests * 200 lines = poor readability of the actual code """ What I mean is that I put all my tests with documentation explanations on the top of the module, so you have to scroll stupidly to find the actual code, and this is quite ugly (in my opinion). However, I think that the doctests should still stay in the module, because you should be able to read them while reading the source code. So here comes my question : sphinx/doctests lovers, how do you organize your doctests, such as the code readability doesn't suffer ?

• Just when I thought my site was working right, it screws up in IE7

  - by John

  I thought I'd done quite well, my site passed XHTML1.0 strict validation and worked flawlessly in IE6 as well as looking fine in IE8 & Chrome. I glibly thought that it it worked in IE6 & 8, IE7 was bound to be OK. But on checking I see one of my has a scrollbar in IE7, the seems about 200% as wide as it should be... the content is fine but you can scroll the whole . 2 separate pages have this issue, a 3rd does not, even though all pages use the same layout template - the main difference on the 2 that break is a floated div. Are there known issues specifically in this area with IE7? Or do I have to embarrass myself by posting a link to the site?

• iOS iPad Master Detail template can't interact with detail view

  - by CraigularB

  I have an iPad app generated from the Master-Detail template in XCode. The iPad Storyboard has under the Detail View Controller a View that holds a ScrollView which holds an ImageView. In the DetailViewController.m file I added the following code to allow the ScrollView to move and zoom the image: -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.comicImage; } This works great on the iPhone (it's a universal app) but not the iPad; I can scroll and zoom the image on the iPhone no problem, but on the iPad it's like the ScrollView isn't responding to the touches, and I can't figure out how to pass the touches on to the ScrollView. I've already deactivated the popover controller from appearing with a right swipe like this: self.splitViewController.presentsWithGesture = NO; How do I make it so the user can interact with the ScrollView in the DetailViewController?

• How can I implement lazy loading on a page with 500+ images?

  - by Fedor

  I basically have a booking engine unit results page which must show 40 units and per each unit there's 1 large image of the first thumbnail and an X number of accompanying thumbnail images. I've been using the jquery lazy load plugin, but it's not thorough enough ( I'm invoking it on DOM Ready ), plus it doesn't really work in IE ( 50% of the clients use IE so it's a big issue ). What I think I really need to do is not really spit out the image but a fake element such as a span, and possibly modify my code such that if the user views the span, render it into an image element. <span src="/images/foo.gif"> The booking engine relies on JS so I think I might be forced to just rely on ajaxifying all the thumbnails and have event handlers on window scroll, etc in order for the page to be "usable" and load at an average time ( 2-3 seconds instead of 5-30s on high speed DSL/Cable ). I'd appreciate any examples or ideas.

• Paging a UIScrollView with a large PDF

  I try to create a simple UIScrollView with paging. And I want to be able to scroll through a large PDF document, but this gives me some problems... I tried the following options: Convert all the PDF pages to UIImages at startup, this works, but is very slow on start Manually drawing the PDF page in the drawRect, but yet again this was slow... And I prefer not to load everything at startup but to do it during the usage. Did anyone did this recently? Can't seem to find a nice example project. Thnx! Jelle

• Cannot move ckeditor 4 selection to beginning

  - by Gary Hillerson

  I've been exploring numerous solutions in stackoverflow and elsewhere to try to get ckeditor 4 to scroll to the top after I've programmatically added a number of pages to it, using CKEditor's InsertHtml function. After adding my html, which looks fine, I want to position the cursor at the beginning. Here's one of a variety of things I've tried without success: function MoveCaretToStart(myEditor) { var range = new CKEDITOR.dom.range( editor.document ); range.selectNodeContents(editor.document.getBody()); range.moveToElementEditStart(range.root); // also tried range.collapse(true); range.select(); } ... MoveCaretToStart(CKEDITOR.instances['myEditor']); // which already has contents in it This doesn't throw any errors, but also doesn't move the cursor position (it remains at the end of the doc). I thought this one would be easy, but it sure hasn't been. Any help appreciated.

• Basic javascript function

  - by McDan Garrett

  I have this function working <script type="text/javascript"> $(window).scroll(function() { if ($(window).scrollTop() == $(document).height() - $(window).height()) { $('div#loadmoreajaxloader').show(); $.ajax({ url: "loadmore.php?wall=<?php echo $wall; ?>&lastid=" + $(".postitem:last").attr("id"), success: function(html) { if (html) { $("#postswrapper").append(html); $('div#loadmoreajaxloader').hide(); } else { $('div#loadmoreajaxloader').html('<center><font color="white">No more posts to show.</font></center>'); } } }); } }); </script> But I need to have the same stuff happening (on IOS Devices), but instead of it happening when the browser reaches the loadmoreajaxeloader div, I simply need it to happen on an onclick event on a link. Thanks heaps. Tried to add code but didn't format so here it is http://pastebin.com/p2VUqZff

• tableView resize problem when pushing another view while keyboard is showing

  - by Rollin_s

  I have a tableview controller under a navigation controller. Some of my table cells contain text fields, so when I tap on them, a keyboard will show up and automatically resize (shrink) the bounds of my tableview. The bounds is then restored when the keyboard is dismissed programmatically by calling resignFirstResponder on my text field. Some of my cells would push a new view controller into the view stack when tapped on, so I first resign my current textfield before pushing the view controller: - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (currentEditingTextField != nil) { [currentEditingTextField resignFirstResponder]; currentEditingTextField = nil; } return indexPath; } The problem is when I navigate back to my table view, the bounds of the tableview is sized as if the keyboard is still there. I know this because the scroll indicator only reaches right above where the keyboard was and there is empty view space below the table view. Anybody experienced this and know of a solution? Thanks

• jQuery > reset popup window 's x and y relative to icon that launched the window

  - by Scott B

  I have a jQuery jPicker colorpicker that is bound to an input text field and opens onclick of a small picker.gif icon. The problem I'm having is that (1) The colorpicker that opens does not appear to be positioned according to the x/y position of the picker.gif (it opens far away from the click point) and (2) The colorpicker does not seem to be aware of the viewport's scroll position (the top of the colorpicker is partially hidden at the top of the window). I'd like to use jQuery to reposition the colorpalette (1) Based on the x/y position of the input that its bound to and (2) reset it's top position based on the viewport's visible Y position. Here is the script where I am creating a new jPicker and binding it to my input text fields for header and sidebar... $('#myHeaderColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } ); $('#mySidebarColor').jPicker ( {}, function(color) { $(this).val(color.get_Hex()); }, function(color) { $(this).val(color.get_Hex()); } );
