  • matplotlib - write TeX on Qt form

    - by race1
    I'd like to add some TeX text to my Qt form, like label - just text, no graph, no lines, no borders, just TeX. I thought something like this: render TeX to bitmap and then place that bitmap on form, e.g. into QLabel. Or even better - use some backend, add it to form and use something tex_label.print_tex(<tex code>). Seems matplotplot has TeX parsers, but I can't figure out how to use them... Thanks.

  • IE6 and IE7 Input padding CSS

    - by Podlsk
    I have input boxes with a height of 25 pixels. In Firefox, Safari and IE8 automatically vertically align the text of it in the middle correctly. However in IE6 and IE7 the text is aligned to the top. How may I resolve this? Adding padding-top increased the total height of the input as I have explicitly declared its height. I don't wish to use browser specific CSS. Thanks.

    - by Shawson
    Hi All, I'm hoping someone can help me with this as I'm at a loss. I'm trying to simply load a plain text file into a page at runtime using jquery- everything works fine in IE8 (8.0.7600.16385), Firefox 3.6.3, however in Google Chrome 5.0.375.55 the "data" comes back as nothing- i get an empty alert box. This is the code i'm using; <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Animation Test</title> <script type="text/javascript" language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> $(document).ready(function () { $.ajax({ url: 'level1.txt', success: function (data) { alert(data); }, async: true, type: 'GET' }); }); </script> </head> <body> <canvas id="canvas" width="640" height="480"> Unsupported Browser </canvas> </body> </html> The file I'm loading in is a plain text file containing this; Central Cavern 100 O.........1.C....C...........1.O O................1.............O O..............................O O..............................O O......................B1..B...O O=============~~~~=~~~~========O O.............................1O O===...........................O O............A..OOO.B..........O O====...<<<<<<<<<<<<<<<<<<<<...O O............................==O O..............................O O..........B........OOO.....===O O....===============...........O O%............................XO O==============================O (Yes- it's the first level from Manic Miner! I'm making a javascript version using the html5 canvas to get my head around using it.)

What is the right way to add the button icons? As in my code I had to add it two times, once: $( "#user-form" ) .button() .click(function() { $(this).effect("transfer",{ to: $("#form") }, 1500); $( "#form" ).dialog( "open" ); ... and $(".files, .email, .event, .map").click(function(){ ... Could this code be improved further? I don't seem to be able to get the "transfer" effect to work correctly in a modal. I added: , close: function() { $(this).effect("transfer",{ to: $("#user-form") }, 1500); } to the $( "#form" ).dialog({ How would you go about in getting the "transfer" to work nicely when you open and close the dialog box?

    - by Mrgreen
    Is there any way to convert a PDF to Word document via code? I'm aware of several online sites that will do it however we cannot use them due to security concerns. Opening the PDF in Adobe, copying all of the text and pasting into Word will not work as all of the text ends up jumbled around the place. Is there any kind of utility that might accomplish converting PDF to Word (or rtf)?
