GWT Linechart options

由 给你一囗甜甜゛ 提交于 2020-01-11 10:14:13
问题 I need to set different line width to different series in a chart. This can be done using the series option here http://code.google.com/intl/sv-SE/apis/chart/interactive/docs/gallery/linechart.html#Configuration_Options . However this option is not available in GWT which leads to my question. I could: Write a wrapper for GWT. http://code.google.com/p/gwt-google-apis/wiki/VisualizationNewWrapper Use the Options.set(...) method. http://gwt-google-apis.googlecode.com/svn/javadoc/visualization/1

Debugging in GWT Super Dev Mode?

由 本小妞迷上赌 提交于 2020-01-11 02:31:46
问题 So far, debugging in GWT super dev mode seems to be a real pain. If there are any errors, there is no stack trace, just a cryptic message given in the chrome console. Is there a way to get all errors to print a stack trace, like in the dev mode? I already have source maps on I believe, since if I go to Sources in Chrome's dev tools, I can see the source code of my java classes. 回答1: GWT.setUncaughtExceptionHandler lets you set an exception handler, which will handle all exceptions. You can

五分钟让你彻底了解TDD、ATDD、BDD&RBE

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 实践测试驱动开发（TDD） 在 目前比较流行的敏捷开发模式（如极限编程、Scrum方法等）中，推崇“ 测试驱动开发 （Test Driven Development，TDD）”——测试在先、编码在后的开发实践。TDD有别于以往的“先编码、后测试”的开发过程，而是在编程之前，先写测试脚本或设计测试用例。TDD在敏捷开发模式中被称之为“ 测试优先的编程 （test-first programming）”，而在IBM Rational统一过程（Rational Unified Process，RUP）中被称为“ 测试优先的设计 （test-first design）”。所有这些，都在强调“ 测试先行 ”，使得开发人员对所做的设计或所写的代码有足够的信心，同时也有勇气进行设计或代码的快速重构，有利于快速迭代、持续交付。 重构的前提就是测试就绪（testing is ready），在这样的前提下，重构的风险就很低，否则就有比较高的风险。 TDD具体实施过程，可以看作两个层次，如图1所示： 在代码层次，在编码之前写测试脚本，可以称为单元测试驱动开发（Unit Test Driven Development，UTDD） 在业务层次，在需求分析时就确定需求（如用户故事）的验收标准，即验收测试驱动开发（Acceptance

GWT-RPC vs HTTP Call - which is better?

问题 I am evaluating if there is a performance variation between calls made using GWT-RPC and HTTP Call. My appln services are hosted as Java servlets and I am currently using HTTPProxy connections to fetch data from them. I am looking to convert them to GWT-RPC calls if that brings in performance improvement. I would like to know about pros/cons of each... Also any suggestions on tools to measure performance of Async calls... [A good article on various Server communication strategies which can be
