一个系统包含的操作都是很多的，这里我总结一下我使用过的三类操作
1.一类是标准的系统内置的操作，可以直接使用的操作，下面从左到右依次是打开透视图，打开快速视图，打开视图，打开视图操作
2.一类是自定义的普通的操作类，任何时候它都可以看到（并不代表它一定是可以触发的），一般可以将之同时设置到菜单栏和工具栏
例如这里的打开导航视图和打开搜索视图的工具栏操作按钮3.另一个类是操作的代理类，它可以绑定到某一个特定的编辑器Editor上（EditorAction），或者是视图View上（ViewAction），它一般是不可复用的，它只是针对某个特定的对象
例如这里的Edit菜单项，它只在右侧出现了病人信息管理时才有实例一：标准操作，这些内容在ApplicationActionBarAdvisor 类中都有定义，因为这个类就是专门用来定义Action的
这些操作的实现一般都是，首先通过ActionFactory创建，然后注册这个action（注：打开视图列表的action不用注册，注册会报错）
// 定义“打开透视图”操作
perspectiveAction = ActionFactory.OPEN_PERSPECTIVE_DIALOG.create(window);
register(perspectiveAction);
perspectiveAction = ActionFactory.OPEN_PERSPECTIVE_DIALOG.create(window);
register(perspectiveAction);

实例二：继承自Action类的OpenPatientInfoViewAction操作，其他的类似的操作还有OpenNavigatorViewAction类等等
操作Action中一般都会有一个IWorkbenchWindow window引用，然后在构造方法中初始化，设置text和image
主要方法就是run，执行对应的操作
package com.yinger.patientims.actions;
import org.eclipse.jface.action.Action;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.ui.IWorkbenchWindow;
import com.yinger.patientims.Activator;
import com.yinger.patientims.util.PluginUtil;
//自定义的action
public class OpenPatientInfoViewAction extends Action {
private final IWorkbenchWindow window;
public OpenPatientInfoViewAction(IWorkbenchWindow window){
this.window = window;
//设置菜单项文本，并给该菜单项添加快捷键以及键绑定
this.setText("&PatientInfo@Ctrl+P");
//工具栏上提示性信息
this.setToolTipText("Open PatientInfo View");
//添加工具栏图形按钮
this.setImageDescriptor(Activator.getImageDescriptor("/icons/User.ico"));
}
public void run(){
if (window!=null) {
try {
//打开视图
window.getActivePage().showView(PluginUtil.PatientInfoView_ID);
} catch (Exception e) {
//创建错误对话框
MessageDialog.openError(window.getShell(), "Error", "Error in opening view :"+e.getLocalizedMessage());
}
}
}
}
import org.eclipse.jface.action.Action;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.ui.IWorkbenchWindow;
import com.yinger.patientims.Activator;
import com.yinger.patientims.util.PluginUtil;
//自定义的action
public class OpenPatientInfoViewAction extends Action {
private final IWorkbenchWindow window;
public OpenPatientInfoViewAction(IWorkbenchWindow window){
this.window = window;
//设置菜单项文本，并给该菜单项添加快捷键以及键绑定
this.setText("&PatientInfo@Ctrl+P");
//工具栏上提示性信息
this.setToolTipText("Open PatientInfo View");
//添加工具栏图形按钮
this.setImageDescriptor(Activator.getImageDescriptor("/icons/User.ico"));
}
public void run(){
if (window!=null) {
try {
//打开视图
window.getActivePage().showView(PluginUtil.PatientInfoView_ID);
} catch (Exception e) {
//创建错误对话框
MessageDialog.openError(window.getShell(), "Error", "Error in opening view :"+e.getLocalizedMessage());
}
}
}
}
实例三：添加病人信息的操作Action
在扩展中添加一个editorActions扩展，新建一个editorContributor，然后新建一个menu，再添加一个action
注意editorContributor的targetID属性，这个是很有用的，用于指定是只有在这个editor有效时才会有action有效的！
指定的ActionDelegate类，动作代理类
package com.yinger.patientims.editors.editorActionDelegate;
import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.jface.wizard.WizardDialog;
import org.eclipse.swt.widgets.Display;
import org.eclipse.ui.IEditorActionDelegate;
import org.eclipse.ui.IEditorPart;
import com.yinger.patientims.sigleton.PatientFactory;
import com.yinger.patientims.wizards.AddPatientInfoWizard;
/**
* 编辑器动作的代理类
*
* 具体的设置在plugin.xml文件中
* 设置了action在菜单栏，工具栏的位置，以及要调用的动作代理类（也就是本类）
* 它不是一个action，但是作用相当于一个action，它可以关联到一个编辑器
* 当这个编辑器editor激活时，相应的动作action就会呈现出来，具体的执行操作还是在这里实现的
*
* TODO:内有一个IEditorPart对象，但是具体的作用？
*
*/
public class PatientEditorActionDelegate implements IEditorActionDelegate {
private IEditorPart editorPart;
@Override
public void run(IAction action) {
//创建自定义的向导
AddPatientInfoWizard wizard = new AddPatientInfoWizard();
//注意：每次打开向导页面时都要对PatientFactory的instance进行设置，不然会出现紊乱
PatientFactory.setInstance(null);
//显示向导对话框
WizardDialog dialog = new WizardDialog(Display.getDefault().getShells()[0], wizard);
//设置对话框大小
dialog.setPageSize(-1, 150);//注意：高度要足够的大
//打开
dialog.open();
// editorPart.getEditorInput().
}
@Override
public void selectionChanged(IAction action, ISelection selection) {
}
@Override
public void setActiveEditor(IAction action, IEditorPart targetEditor) {
this.editorPart = targetEditor;
}
}
import org.eclipse.jface.action.IAction;

AddPatientInfoWizard wizard = new AddPatientInfoWizard();
//注意：每次打开向导页面时都要对PatientFactory的instance进行设置，不然会出现紊乱
PatientFactory.setInstance(null);
//显示向导对话框
WizardDialog dialog = new WizardDialog(Display.getDefault().getShells()[0], wizard);
//设置对话框大小
dialog.setPageSize(-1, 150);//注意：高度要足够的大

}
@Override
public void selectionChanged(IAction action, ISelection selection) {
}
@Override
public void setActiveEditor(IAction action, IEditorPart targetEditor) {
this.editorPart = targetEditor;
}
}
这里的添加新的病人信息操作和上节中的那个Action的run方法是一样的，只是这样让用户多了一个选择，他可以选择菜单栏中的选项进行操作
