rendering

问题 Came across this strange result today trying to render a list of objects as JSON in Grails 2.0.4...(i know i'm gonna regret asking this on account of something right under my nose... updated 5/26, my prediction was correct, see below :-)) This works fine; the JSON renders correctly in the browser... def products = [] //ArrayList of Product objects from service def model = (products) ? [products:products] : [products:"No products found"] render model as JSON ..so why doesn't this shortened

问题 I`ve got a mysterious problem with my custom JTable and a custom TableRenderer. In 95%-99,99% it works perfectly, but sometimes the renderer just stops doing his job, and leaves a portion of the table (which is inside a JScrollPane) blank. The problem case looks like that: In all other cases, and after a slight resize of the window, the Table look like that: Now both columns has a TextAreaCellRenderer associated to, which works as follows: public class TextAreaCellRenderer extends JTextArea

问题 How to do a column level render in datatable in jsf without using ajax? For example, First column having a Drop down menu selection. Based on the selection, I need to enable button in the second column. Can any one help me on this. 回答1: If by "column level render" you mean "a way to rerender a single column in table" then the answer is - you can't. Browsers do not allow this. You would need to rerender each td in a colimn separately. If you just mean "change some parts of the table on the fly

问题 I do not really understand the way I'm suppose to render a side-scroller? How do I know what to render when my character move? What kind of positionning should I use for the characters? I hope my question is clear 回答1: The easiest way i've found to do it is have a characterX and characterY variable [integer or float, whatever you want] Then have a cameraX and cameraY variable. Every object in the scene is drawn at theObjectX-cameraX, theObjectY-cameraY... CameraX/CameraY are tweened by a

问题 I wonder why I have a very bad rendering when I use the Painters custom renderer in figure Export Setup? Look at this image which has used OpenGL: and this one, which has used Painters. What the hell is going on here? 回答1: There's a bug in 2014b-2015a. The easiest way to fix this is to upgrade to 2015b or newer. I had a workaround where I used matlab2tikz but that took a bit of work for my application. I don't believe there to be a workaround that can create .png files from Matlab that works

问题 Long story short With knp-snappy-bundle I can't generate a header in the PDF, while I can actually generate a footer. Is it a bug, a feature, or I'm doing something wrong? Details 1. Environment I'm testing the knp-snappy-bundle , I've also installed the wkhtmltopdf binary from h4cc . This is part of my composer.json : "h4cc/wkhtmltopdf-amd64": "^0.12.3", "knplabs/knp-snappy-bundle": "^1.5", The resulting binary of wkhtmltopdf says this: $ vendor/bin/wkhtmltopdf-amd64 --version wkhtmltopdf 0

问题 I'm looking forward to implement a LookAt( forward, up ) method where: Vector3 forward = eyePosition - targetPosition; Vector3 up; I've seen some implementations over the web, but analizing the code, I've found potencial misbehaviors... I list them from easiest to hardest: 1) This won't work if UP is a zero vector. 2) This won't work if FORWARD is a zero vector. 3) This won't work if UP and FORWARD are parallels. ... So.. How should this method correctly be implemented? Here is a code example

问题 I am trying to find the best way to export a complex vector graphic (i.e., an architectural plan, weighing in at several megabytes uncompressed) for optimal display on the web – and I wonder, if the generally recommended SVG 1.1 option in Illustrator is the best choice. From what I've learned so far, Scalable Vector Graphics Tiny 1.2 specification ... used to have limited viewer support , but not anymore. has no effect on file size; best way to reduce it is by shaving off unnecessary decimals

问题 I can't understand what is "rendering a view". I'm reading Zend Framework manual and there are a lot of usage of this term. Automatically rendering views: This helper takes care of injecting the view object into the controller, as well as automatically rendering views. Disable rendering for a view: You can also simply disable rendering for an individual view render() renders a view script. render() renders a view script. Render that template in the subdirectory Passing a value for $action
