看得出来它是在JDT UI里面定义的，l合了jdt text editor template ?Java开头的category 和custom editor template如SWT开头的category。对于我来说QSWT/Draw2d/Plugin的大量重复性代码就可以通过q个来完成了。将模板的代码插入到~辑器有两种ҎQ一U是直接拖拽到编辑器中，另一U是输入写入?execute"Q按Contxt Assist快捷?一般ؓCtrl+Space)?br />
除此之外QTemplates Viewq可以维护template比如add/remove。Template的gXML字串存放?metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.jdt.ui.prefs文g的org.eclipse.jdt.ui.text.custom_templates?br /> 起初我以为Template View好像q没有提供什么NB功能Q在Window->Preferences->Java->-Editor->Templates可以做同L事情Q但E微看了一下代码，发现我错了：
Templates View是PageBookViewQ意味着它跟Properties View/Outline View一P可以Ҏ不同的Editor来显CZ同的PageQ比如上图JDT是JavaTemplatesPageQ如果编写一个DSL Editor需要用到Templates ViewQ承AbstractTemplatesPageQ然后在Editor的getAapter()q回pageQ看Java EditorCZQ?br />
public class CompilationUnitEditor extends JavaEditor implements IJavaReconcilingListener {
public Object getAdapter(Class required) {
if (SmartBackspaceManager.class.equals(required)) { if (getSourceViewer() instanceof JavaSourceViewer) { return ((JavaSourceViewer) getSourceViewer()).getBackspaceManager();
} } if (ITemplatesPage.class.equals(required)) { if (fTemplatesPage == null) fTemplatesPage= createTemplatesPage(); return fTemplatesPage; } return super.getAdapter(required); protected JavaTemplatesPage createTemplatesPage() { return new JavaTemplatesPage(this); }}当然Q大部分Z需要写editorQ我们可以在自己的插仉通过使用扩展Ҏorg.eclipse.ui.editors.templates扩展JDT TemplateQ比如我在GEF目里面加入了GEF TemplateQ这L写讨厌的EditPart/EditPolicy/Command可以少些好多代码?br />
W一张图片看到的swt template是在上图所C的default-swttemplates.xml里面定义好了的?br />
最后想告诉q大Eclipse爱好者的是QEclipse SDK写的代码真工_果然是协作的l晶Q整一个代码宝库，Ҏ不用?strong>代码大全?)?

即在GMF? DiagramAction也是取得是鼠标点击paste时的位置Q而不是之前右键单d现contxt menu的位|。这?strong>“定点”关键是在选择paste之前右键单击的位|已l被C了，q且对context menu中所有对位置敏感的action都有效，比如merge, duplicate{?br />
下面分三步完成：
1 定义一个接口，为所有位|敏感action提供位置信息
public interface ILocationWare {
void setLocation(int x,int y);
}
void setLocation(int x,int y);
}
2 注册一个listener到GEF editor的context menuQ提供位|记忆，q个是关键?/strong>

private IMenuListener listener = new IMenuListener(){

public void menuAboutToShow(IMenuManager manager) {
Control canvas = getViewer().getControl();
Point cursor_location = canvas.getDisplay().getCursorLocation();
Point relative_canvas = canvas.toControl(cursor_location);
setItemLocation(manager,relative_canvas);
}
private void setItemLocation(IMenuManager manager, Point relative_canvas) {
IContributionItem[] items = manager.getItems();
for (int i =0; i < items.length; i++)
{
IContributionItem item = items[i];
if (item instanceof ActionContributionItem)
{
IAction host_action = ((ActionContributionItem)item).getAction();
if (host_action instanceof ILocationWare)
((ILocationWare)host_action).setLocation(relative_canvas.x, relative_canvas.y);

editor = lv;
addMenuListener(listener);
}
.
.
.
@Override
public void dispose() {
removeMenuListener(listener);
super.dispose();
}
}
原理是右键单击后，context menu的listener已经C了鼠标在graphicalviewer control(一般ؓFigureCanvas)叛_位置Qƈ告知l所有context menu中对位置敏感的action?br />

public class PasteAction extends SelectionAction implements ILocationWare {
private Point location = new Point(10,10);
private boolean contextTrigged=false;
public PasteAction(LivingEditor part) {
super(part);
}
@Override
public void run() {
//some operations depend on location
}
@Override
public void setLocation(int x, int y) {

}
@Override

super.init();

ISharedImages workbench_images = PlatformUI.getWorkbench().getSharedImages();
setImageDescriptor(workbench_images.getImageDescriptor(ISharedImages.IMG_TOOL_PASTE));
setDisabledImageDescriptor(workbench_images.getImageDescriptor(ISharedImages.IMG_TOOL_PASTE_DISABLED));
}
}
private Point location = new Point(10,10);
private boolean contextTrigged=false;
public PasteAction(LivingEditor part) {
super(part);

//some operations depend on location

setImageDescriptor(workbench_images.getImageDescriptor(ISharedImages.IMG_TOOL_PASTE));
setDisabledImageDescriptor(workbench_images.getImageDescriptor(ISharedImages.IMG_TOOL_PASTE_DISABLED));

q种解决同样适用于GMF的DiagramAction?DiagramAction也是Action的子c?

]]>1 用maven创徏一个web project
mvn archetype:create -DgroupId=com.lifesting -DartifactId=test -DarchetypeArtifactId=maven-archetype-webapp
2 补全某些目录
cd test\src
mkdir main\java
mkdir test\resources
mkdir test\java
3 修改pom文gQ在生成eclipse目的时候maven eclipse plugin使用此配|?br /> 在project/build下面插入
<plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-eclipse-plugin</artifactId> <configuration> <projectnatures> <java.lang.String>com.genuitec.eclipse.j2eedt.core.webnature</java.lang.String> <java.lang.String>org.eclipse.jdt.core.javanature</java.lang.String> </projectnatures> <outputDirectory>src/main/webapp/WEB-INF/classes</outputDirectory> </configuration> </plugin> </plugins> facelet-- com.genuitec.eclipse.jsf.faceletsnature

IProject project = ResourcesPlugin.getWorkspace().getRoot().getProject("test"); try { String[] natures = project.getDescription().getNatureIds(); for (String nature :natures) System.out.println(nature); } catch (CoreException e) { e.printStackTrace(); }outputDirectory主要是告诉maven eclipse plugin~译输出在什么位|，默认在target/classes下面Qweb目不同Q应该放在src/main/webapp/WEB-INF/classes 才能够被MyEclipse package到服务器?br />

5 在MyEclipse中将test project 导入到workspaceQMyEclipse通过projectNature识别到test是一个MyEclipse web projectQ它会在目目录下生成一?mymetadata文g。再关闭MyEclipseQ这么做的原因是因ؓ默认MyEclipse的webRoot不可配置?br />
6 修改MyEclipse下面?mymetadata文gQ比如我的test目文g内容?br />
<?xml version="1.0" encoding="UTF-8"?><project-module type="WEB" name="test" id="myeclipse.1207117121765" j2ee-spec="1.4" archive="test.war"> <attributes> <attribute name="webrootdir" value="/WebRoot" /> </attributes></project-module><?xml version="1.0" encoding="UTF-8"?><project-module type="WEB" name="test" id="myeclipse.1207117121765" context-root="/test"" j2ee-spec="1.4" archive="test.war"> <attributes> <attribute name="webrootdir" value="/src/main/webapp" /> </attributes></project-module>可以看到Q增加的一?context-root="/test" 表示web的上下文为test.
