问题 I am trying to create a Custom Flex Component using the Flex Component framework: http://www.adobe.com/livedocs/flex/3/html/help.html?content=ascomponents_advanced_3.html. All good components allow you to define their dimensions using percentage values using: MXML: TextInput width="100%" or Actionscript at runtime: textinp.percentWidth = 100; My question is how do you implement percentage width/height in the measure() method of your custom component? More specifically, these percentages are

问题 I created my own MyScrollbarUI class to have a custom scrollbar look in my application. Now I have to do scrollPane.getHorizontalScrollBar().setUI(new MyScrollbarUI()); scrollPane.getVerticalScrollBar().setUI(new MyScrollbarUI()); on any ScrollPane I use. Is it somehow possible to tell Swing that it should use MyScrollbarUI on any scrollbar. Maybe via the UIManager ? 回答1: UIManager.put("ScrollBarUI", MyScrollbarUI.class.getName()); should do the trick. You need to have a public static

问题 I'm new to Flex and am porting a pure Flash/AS3 app to Flex 4.5 I've created a custom MXML component based on BorderContainer <?xml version="1.0" encoding="utf-8"?> <s:BorderContainer xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="160" height="140" > <s:Image id="_avatar" enableLoadingState="true" x="0" y="0" width="160" height="120" /> <s:Label id="_username" x="0" y="125" fontSize="12" fontWeight="bold" /

问题 I have been developing a number of components using TFrames and ModelMaker -- I've found the combination of visual design/development + inheritance + ModelMaker to be very compelling. I then register these TFrame descendants w/a registration unit, and they become full-fledges palette-based components from there. I'm using Delphi 2007. Early in my learning about the little "snags" of this process, I found that a number of the problems I would run into with TFrame descendants streaming
