问题 Using: Rails 3.2.11 & Ruby 1.8.7 I am having some serious problem trying to make label_tag output html.

How can I make label text scale-able in Winforms application

阅读更多关于 How can I make label text scale-able in Winforms application

问题 I am looking for a way to make text in a label scale-able to it fit in entire parent container. The one way I can think of is to get the container size on window re-size and then increase or decrease font size accordingly, but that would limit its possibilities. Wondering if there is a better way of doing this, that may work more like an anchor property in Winforms application. 回答1: I knew the answer is hidden somewhere in graphic object and paint event, playing around with these 2 keywords

来自Ray：恭喜各位！你们已经通过宣传 ios feast 提前解锁了第一个有关IOS6的教程。目前这份教程只是我们的新书 iOS 6 By Tutorials 里面某个章节的精简版。这份教程由同样著作过 iOS Apprentice Series 的Matthijs Hollemans 完成，开始体验吧! 这份教程由IOS 教程小组的组员 Matthijs Hollemans 发布， Matthijs 既是一位经验丰富的IOS程序员又是一名资深老到的界面设计者。. 在这系列教程的第一部分你见识到了旧的“struts-and-springs” 模式不能简单的解决所有的用户界面布局问题。新的IOS 6特征是一种解决方案，但因为这个技术是如此的有效，它使用起来还是有点小棘手的。在这系列教程的第二部分也是最后一部分, 你将继续学习constraint的概念以及如何运用他们! 大胆尝试constraint 也许你已经注意在canvas里面到有些T型状对象看上去比其他的要粗一点。这些加粗的，我们称之为 user constraints ，你删除它们后的效果和删除细的是不同的。当你删除一个 user constraints ，Interface Builder经常会自动在删除的地方放置一个不可删除的constraint来代替之。我马上就会讲到为什么会这样。在文档概要图中，user

阅读更多关于 Using CSS to switch left/right position of and in IE7+

I have a form comprising a sequence of <label> , <input> pairs (one per line) as follows: <ol style="list-style: none;"> <li class="normal"> <label>Channel Name</label> <input type="text"> </li> <li class="reversed"> <label>Subscribe to this channel</label> <input type="checkbox"> </li> </ol> I'm looking for a pure-CSS way to modify the second line to display the <input> checkbox to the left of the <label> (i.e. exchange their order without modifying the HTML). The following simple rule works perfectly in Firefox, Chrome, Safari, Opera, IE8+... li.reversed input { float: left; } ... but it

D3.js force layout - edge label placement/rotation

阅读更多关于 D3.js force layout - edge label placement/rotation

问题 I'm pretty new with D3.js, and I've been playing around with force layout. One of the things I tried was placing labels on links. One way of doing it is by appending svg:text and manually calculating translate & rotate , which works fine with straight lines. But, in case when link is a svg:path (e.g. arc), this doesn't work as expected. In these cases, svg:textPath is suggested solution. In this demo, you can see a simple implementation of adding labels to links through svg:textPath . The

Extending GWT's Widget Class

阅读更多关于 Extending GWT's Widget Class

I'm making a new class called 'Cell' which extends the GWT Widget class. The purpose of this class is to be a cell in a spreadsheet -- it therefore must be able to switch between being a GWT Label object and a GWT TextBox object. The only way that I can think of doing this is by making Cell extend Widget and include a private Widget called 'cell' which I can store the current Label or TextBox object with. Like so... public class Cell extends Widget { private Widget cell; ... } Unfortunately, this solution is not ideal because if I want Cell to fully operate like a Widget, I will have override
