  • iPhone: scale UIView about a specific point

    - by Greg Maletic
    I want to animate the scaling down of a UIView, but not about its center: about a different point. As a shot in the dark, I tried translating the view, scaling, then translating back, using a series of CGAffineTransforms. But it doesn't work: it still scales about the center. Anyone know how to do this? Thanks very much.

  • Making a JQuery tooltip retrieve a new value every time the mouse moves.

    - by Micheal Smith
    As i am developing an application that makes use of a tooltip that will display a different value when the user moves the mouse. The user mouses over a table cell and the application then generates a number, the further right the cursor moves in the cell, the higher the value increases. I have created a tooltip that runs and when the cursor mouses over the cell, it does indeed show the correct value. But, when the i move the mouse, it does not show the new value but just the older one. I need to know how to make it update everytime the mouse moves or the value of a variable changes, Any ideas for the problem? <table> <tr id="mon_Section"> <td id="day_Title">Monday</td> <td id="mon_Row"></td> </tr> </table> Below is the document.ready function that calls my function: $(document).ready(function() { $("#mon_Row").mousemove(calculate_Time); }); Below is the function: <script type="text/javascript"> var mon_Pos = 0; var hour = 0; var minute = 0; var orig = 0; var myxpos = 0; function calculate_Time (event) { myxpos = event.pageX; myxpos = myxpos-194; if(myxpos<60) { orig = myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=60 && myxpos<120) { orig=myxpos; $('#mon_Row').attr("title", orig); } if (myxpos>=120 && myxpos<180) { orig=myxpos; $('#mon_Row').attr("title", orig); Inside the function is the code to generate the tooltip: $('#mon_Row').each(function() { $(this).qtip( { content: { text: false }, position: 'topRight', hide: { fixed: true // Make it fixed so it can be hovered over }, style: { padding: '5px 15px', // Give it some extra padding name: 'dark' // And style it with the preset dark theme } }); }); I know that a new value is being assigned to the cells title attribute because it will display inside the standard small tooltip that a browser will display. The JQuery tooltip will not grab the new value and display it, only the variables initial value when it was called.

  • Make html footer occupy the rest of the body

    - by w0rldart
    So I am trying to code the footer of my web app of it occupies the rest of the body's height. Picture: http://img1.uploadscreenshot.com/images/orig/3/8906151296-orig.png Notice the light area beneath the dark area, the dark area should occupy all of it. Some of my html code: <body> .... <footer> <hr> <ul id="footerContainer"> <li class="right"> <ul> <li> <a href="" class="family-filter">Filtro Fami....</a> </li> </ul> </li> </ul> </footer> <script>...</script> </body></html> CSS: .... #footerContainer {width: 90%; min-width: 525px; margin: 0 auto; position: relative;} .... footer hr{ border: 0; height: 30px; background: url('../imgs/footer-top.png') repeat-x scroll; } footer { background: url('../imgs/footer-bg.png') repeat scroll bottom; height: 100%; display: block; margin: 0 auto; padding: 0; overflow: auto; } #footerContainer {margin: 0 auto; position: relative;} #footerContainer li { display: inline;} #footerContainer li .right {float: right;} #footerContainer li a {} Any suggestions? Update1: This is what happens: http://img1.uploadscreenshot.com/images/orig/3/8906391235-orig.png when I set html,body { width: 100%; height: 100%; margin: 0; padding: 0; } Update2: http://awesomescreenshot.com/0382hf1ff Zoom out and in at this page: line25.com/wp-content/uploads/2010/blog-design-coded/demo/… and check the footer area, that's how I need it work on my layout.

  • Visual marker when moving rows on DataGridView

    - by BlueRaja
    Users drag rows up and down in my DataGridView. I have the dragging logic down-pat, but I'd like there to be a dark marker indicating where the row will be placed after I let go of the mouse. (I've seen this in 1000 places before, but can't seem to find an example right now) Does anyone know how I'd go about doing this? Is this built-in, or would I have to draw my own marker (if so, how do I do that)? Thanks!

  • Does anyone know a light Vim scheme which makes coding more readable and pleasant?

    - by janoChen
    I know a lot of nice dark schemes for Vim which makes coding more readable and pleasant such as ir_black, wombat, zenburn. Its weird but I haven't seen so many popular light themes (white background). Does anyone knows a light Vim scheme which makes code more readable and pleasant to see? (that makes code less confusing to distinguish, something like Visual studio's default scheme?)

  • How to enable iPhone auto lock during MPMoviePlayer playback?

    - by obiwahn
    When I play a video with MPMoviePlayerController in my app my iPhone does not auto lock (tested OS 3.0 & 3.1.2). However, the application.idleTimerDisabled = NO, so this setting is not affected by MPMoviePlayerController. How can I get my iPhone to sleep normally (e.g. after 3 min screen dims, then goes dark) when my app is running and playing a video?

  • How to use JavaScript to measure how bright a users monitor is ?

    - by HankV
    I've noticed that the brightness of computer monitors drastically varies between computers. As such, this changes the look of web pages greatly. Is there a way to use JavaScript to automatically detect how bright (or dark) a users monitor is so that I can adjust my web page colors accordingly? UPDATE Please note that I do not want manual user involvement. I want this detection to be automatic so that users don't realize I dynamically change the color palette automatically based on the brightness/darkness of their monitor.

  • Checking up remotely on Website Usage

    - by Raj More
    A client of mine has a pure HTML website that was built in the dark ages - they want me to find where their users are coming from, how many individual users there are, etc. They want to know if the site is being used enough for them to invest the money into renovating it. I am remote from their site and do not have access to their web server. Is there something like ComScore for small sites that I can go into to check their usage statistics?

  • Is there better documentation then the original OpenAL docs? [closed]

    - by mystify
    OpenAL is such a huge thing, and the documentation doesn't tell what values are acceptable for properties. That's really bad. I'm using the document: "OpenAL_Programmers_Guide.pdf" Whenever I look up a property I'm left in the dark what value might be ok. For example, take AL_PITCH. What value? Maybe someone wrote a better one? Or is there something like a wiki place with more details?

  • Console output spits out Chinese(?) characters

    - by a_person
    This is a real shot in the dark, however maybe someone had a similar issue. Some console apps are being invoked by either SQL Server 2008, or Autosys (job schedule) under Windows Server 2008; output results of execution are being saved into .txt files. Every so often, with no definite pattern as far as I can tell saved output is displayed as a series of what I presume are Chinese characters. Have anyone encountered phenomenon above?
