1.性能

    a. ��用�~�存�q�程资源
       Window -> Preferences -> Internet -> Cache -> 选择Disable Caching
       �q�样在打开web.xml�{�文件时��׃��?Loading xmlns 之类的信息了

    b. ��用有效性验�?BR>       Window -> Preferences -> Validation -> 选择Deselect All
       可能有效性验证是个不错的功能�Q�不�q�有时候需要花的时间太长，有点受不了，基本上也不怎么需�?BR>    c. ��用启动eclipse时自动构�?BR>       Window -> Preferences -> Launching -> 不选择 Build before launching

2.个�h嗜好

在Eclipse安装SVN插�gSubclipse

bigseal — Mon, 15 Aug 2005 04:38:00 GMT

Eclipse 3.0/3.1

Subclipse releases for Eclipse 3.x are hosted at our update site. Add http://subclipse.tigris.org/update as an update site in Eclipse's update manager (which you can find in the Help menu).

The update site itself can be downloaded and used as a local update site as well. Simply unzip the site archive, and add the path as a new "Local Site" in the Eclipse update manager. You can also host your own internal Subclipse update site by placing the site on your own HTTP server (be sure to update site.xml appropriately).

We also provide instructions for installing Subclipse in Eclipse 3.x

Eclipse 2.1.3

Subclipse 0.9.3.3 is linked against Subversion 1.1.4. Binaries for Windows are included.

Development for this version of Eclipse is no longer active. There are no new releases planned.

Download the Eclipse 2.x version

Note�Q?/FONT>如果把文件直接unzip到eclipse的安装目下，在��用的时候会没有授权文�g文�g之类的错误�?BR>

an EMF-based implementation of the UML 2.0 metamodel for the Eclipse platform

bigseal — Fri, 15 Jul 2005 06:06:00 GMT

The UML2 project is an EMF-based implementation of the UML 2.0 metamodel for the Eclipse platform designed to support the development of modeling tools. Further objectives of the UML2 project are to provide a common XMI schema to facilitate interchange of semantic models, test cases as a means of validating the specification, and validation rules as a means of defining and enforcing levels of compliance. For more details see Getting Started with UML2

AWT相关——Graphics引用

bigseal — Wed, 13 Jul 2005 06:07:00 GMT

    有两�U�方法要用到对Graphi的引用，�q�两�U�就是传递一个对Graphi的引用，或返回对Graphics的引用�?BR>
   1 .传递一个对Graphi的引用是诸如 void paint(Graphics g)的方法，通过override该方法来辑ֈ�目的�?BR>

import java.awt.*;

public class SubPanel extends Panel{

    public void paint(Graphics g){
        g.setColor(Color.RED);
        g.drawString("subPanel",5,5);
    }
}

2.�q�回对Graphics的引用是诸如 Graphiics getGraphics() 的方法，直接引用�q�回的Grapchics�?BR>

import java.awt.*;

import java.awt.*;

public class SubPanel extends Panel {

    public void test() {
        Graphics g = getGraphics();
        if (g != null) {
            g.setColor(Color.RED);
            g.drawString("subPanel", 5, 5);

    AWT是JFC�Q�Java基本�c�）的核心，为JFC的构成提供了以下的基本结构：

代理事�g模型

轻量构�g

剪脓板和数据传输

    Java抽象�H�口工具集有四个主要的类�Q�即�Q�构件类�Q�Component�Q�、容器类�Q�Container�Q�、图形类�Q�Graphics�Q�、和布局��理�c�（LayoutManager和LayoutMangager2�Q�。容器包含构�Ӟ��布局��理器确定容器内构�g的位�|�和形状。图形（Graphics�Q�类提供在构件中昄��文本框和囑�Ş的方法�?BR>
1.强制一个容器布�|�它的构�?BR>
    在�Q何时间给定的构�g都是有效�Q�valid�Q�或无效�Q�invalid�Q�的。无效的构�g需要被布置�Q�而有效的构�g不需要。访问一�?无效容器�Q�它的同位体已经产生�Q�的validate()引�v对容器layout()�Ҏ��的调用。��构�g无效的过�E�不仅��构�g自己变得无效�Q�而且也会使构件所在的容器变的无效�?BR>使构件无效的Component和Container�Ҏ��Q?BR>void Component.addNotify()
void Component.show() (invalidates parent container)
void Component.hide() (invalidates parent container)
void Component.reshap(int x,int y,int width,int height)

void Component.setBounds(int x,int y,int width,int height)
void Component.setLayout(LayoutManager)
void Container.add(Component)
void Container.remove(Component)
void Container.removeAll(Component)
void Container.setLayout(LayoutManager)
因此我们可以把希望重新布�|�的构�g讄��为无效，然后调用该构件父容器的validate()�Ҏ��卛_��?BR>
