RCP添加一个编辑器视图
RCP提供专门的编辑器视图，里面内置了很多编辑器的专用用户，如果修改后，视图中名称显示命名，提示已修改要进行保存。
1、plugin.xml中添加视图view扩展点，和org.eclipse.ui.editors扩展点
2、添加以下3个编辑器相关的类
A、JSEditor
package myviewrcp2.editors;
import org.eclipse.core.runtime.IProgressMonitor;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.ModifyEvent;
import org.eclipse.swt.events.ModifyListener;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Text;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IEditorSite;
import org.eclipse.ui.PartInitException;
import org.eclipse.ui.part.EditorPart;
public class JSEditor extends EditorPart{
//对应plugin.xml指定的id
public static final String ID = "myviewrcp2.editors.JSEditor";
private Text text;
//编辑器中的内容是否被修改的标志
private boolean bDity = false;
public JSEditor() {
super();
}
//编辑器关闭时，保存编辑器内容时所调用的方法
@Override
public void doSave(IProgressMonitor monitor) {
// TODO Auto-generated method stub
try {
monitor.beginTask("保存文件....", 100);
for(int i= 0;i<10 && monitor.isCanceled();i++) {
Thread.sleep(500);
monitor.worked(10);
double d = (i + 1)/10d;
monitor.subTask("已完成"+d * 100 + "%");//显示任务状态
}
monitor.done();
if(monitor.isCanceled()) {
throw new InterruptedException("取消保存");
}
}catch(InterruptedException e) {
e.printStackTrace();
}
}
//另存为调用的方法
@Override
public void doSaveAs() {
// TODO Auto-generated method stub
}
//初始化编辑器
@Override
public void init(IEditorSite site, IEditorInput input) throws PartInitException {
// TODO Auto-generated method stub
this.setSite(site);//设置site
this.setInput(input);//设置输入的IEditorInput 对象
this.setPartName(input.getName()); //设置编辑器上方显示的名称
}
//判断是否被修改过
@Override
public boolean isDirty() {
// TODO Auto-generated method stub
return bDity;
}
//是否允许保存
@Override
public boolean isSaveAsAllowed() {
// TODO Auto-generated method stub
return true;
}
//创建编辑器中的控件
@Override
public void createPartControl(Composite parent) {
// TODO Auto-generated method stub
text = new Text(parent,SWT.NONE);
//当文本框修改时，设定内容被修改过
text.addModifyListener(new ModifyListener() {
@Override
public void modifyText(ModifyEvent arg0) {
// TODO Auto-generated method stub
if(!isDirty()) {
setDirty(true); //设置修改
//更改编辑器的状态
firePropertyChange(IEditorPart.PROP_DIRTY);
}
}
});
}
//设置焦点
@Override
public void setFocus() {
// TODO Auto-generated method stub
text.setFocus();
}
public void setDirty(boolean b) {
bDity = b;
}
}
B、JsEditorContributor
package myviewrcp2.editors;
import org.eclipse.jface.action.Action;
import org.eclipse.jface.action.IMenuManager;
import org.eclipse.jface.action.IToolBarManager;
import org.eclipse.jface.action.MenuManager;
import org.eclipse.ui.ISharedImages;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.part.EditorActionBarContributor;
public class JsEditorContributor extends EditorActionBarContributor{
private Action action1;
private Action action2;
public JsEditorContributor() {
super();
makeActions();
}
public void makeActions() {
action1 = new Action() {
public void run() {
}
};
action1.setText("Action 1");
action1.setToolTipText("Action 1 tooltip");
//action1.setImageDescriptor(PlatformUI.getWorkbench().getSharedImages().getImageDescriptor(ISharedImages.IMG_DEF_VIEW));
action2 = new Action() {
public void run() {
}
};
action2.setText("Action 2");
action2.setToolTipText("Action 2 tooltip");
//action2.setImageDescriptor(PlatformUI.getWorkbench().getSharedImages().getImageDescriptor(ISharedImages.IMG_OBJS_WARN_TSK));
}
//创建菜单
@Override
public void contributeToMenu(IMenuManager menuManager) {
MenuManager editMenu = new MenuManager("编辑器菜单");
editMenu.add(action1);
editMenu.add(action2);
menuManager.add(editMenu);
}
//覆盖父类的方法，创建工具栏
@Override
public void contributeToToolBar(IToolBarManager toolBarManager) {
toolBarManager.add(action1);
toolBarManager.add(action2);
}
}
C、JsEditorInput
package myviewrcp2.editors;
import org.eclipse.jface.resource.ImageDescriptor;
import org.eclipse.ui.IEditorInput;
import org.eclipse.ui.IPersistableElement;
public class JsEditorInput implements IEditorInput{
//输入字符
private String input;
public JsEditorInput(String input) {
this.input = input;
}
//返回与该输入相关的类的对象
@Override
public <T> T getAdapter(Class<T> arg0) {
// TODO Auto-generated method stub
return null;
}
//是否将编辑器保存在最近访问记录中
@Override
public boolean exists() {
// TODO Auto-generated method stub
return true;
}
//输入内容的图标
@Override
public ImageDescriptor getImageDescriptor() {
// TODO Auto-generated method stub
return null;
}
//输入信息的名称
@Override
public String getName() {
// TODO Auto-generated method stub
return input;
}
//是否可以持久化该编辑器
@Override
public IPersistableElement getPersistable() {
// TODO Auto-generated method stub
return null;
}
//设置编辑器标签中显示提示信息
@Override
public String getToolTipText() {
// TODO Auto-generated method stub
return input;
}
}
3、添加了一个打开编辑器的视图类OpenEditorView
package myviewrcp2.views;
import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.List;
import org.eclipse.ui.IWorkbenchPage;
import org.eclipse.ui.PartInitException;
import org.eclipse.ui.part.ViewPart;
import myviewrcp2.editors.JSEditor;
import myviewrcp2.editors.JsEditorInput;
public class OpenEditorView extends ViewPart{
public static final String ID = "myviewrcp2.views.OpenEditorView";
public List list;
public OpenEditorView() {
super();
}
@Override
public void createPartControl(Composite parent) {
// TODO Auto-generated method stub
list = new List(parent,SWT.NONE);
list.add("Editor");
list.add("MutiPage Editor");
list.add("Form Editor");
list.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(SelectionEvent e) {
String select = list.getSelection()[0];
//获得当前激活IWorkbenchPage对象
IWorkbenchPage page = getViewSite().getWorkbenchWindow().getActivePage();
if(select.equals("Editor")) { //如果选中“Editor”项
//创建输入的内容对象
JsEditorInput editor = new JsEditorInput(select);
try {
//打开该编辑器
page.openEditor(editor, JSEditor.ID);
}catch(PartInitException ee) {
ee.printStackTrace();
}
}
}
});
}
@Override
public void setFocus() {
// TODO Auto-generated method stub
list.setFocus();
}
}
4、修改透视图显示
5、效果
