eclipse插件练习二----Diglog的使用

DiglogSample类:
package com.example.myhello.actions;

import org.eclipse.jface.dialogs.Dialog;
import org.eclipse.jface.dialogs.IDialogConstants;
import org.eclipse.jface.window.IShellProvider;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Text;

public class DialogSample extends Dialog{

private String textValue = "我爱JAVA";
//将Text设为类变量，否则buttonPressed方法无法访问 private Text text;
private Text text;

protected DialogSample(Shell parentShell) {
super(parentShell);
// TODO Auto-generated constructor stub
}

protected Control createDialogArea(Composite parent) {
getShell().setText("标题");
//设置Dialog的标头
Text text = new Text(parent, SWT.BORDER);
//设置一个Text控件
text.setText("我爱JAVA");
//设置text中的内容
return parent;
}

protected int getShellStyle() {
return super.getShellStyle() | SWT.RESIZE | SWT.MAX;
}

}

SimpleAction类:
package com.example.myhello.actions;

import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.jface.window.IShellProvider;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.IWorkbenchWindowActionDelegate;
import org.eclipse.jface.dialogs.Dialog;
import org.eclipse.jface.dialogs.MessageDialog;

/**
* Our sample action implements workbench action delegate.
* The action proxy will be created by the workbench and
* shown in the UI. When the user tries to use the action,
* this delegate will be created and execution will be
* delegated to it.
* @see IWorkbenchWindowActionDelegate
*/
public class SampleAction implements IWorkbenchWindowActionDelegate {
private IWorkbenchWindow window;
/**
* The constructor.
*/
public SampleAction() {
}

/**
* The action has been activated. The argument of the
* method represents the 'real' action sitting
* in the workbench UI.
* @see IWorkbenchWindowActionDelegate#run
*/
public void run(IAction action) {
DialogSample dialog = new DialogSample(window.getShell());
dialog.open();
}

/**
* Selection in the workbench has been changed. We
* can change the state of the 'real' action here
* if we want, but this can only happen after
* the delegate has been created.
* @see IWorkbenchWindowActionDelegate#selectionChanged
*/
public void selectionChanged(IAction action, ISelection selection) {
}

/**
* We can use this method to dispose of any system
* resources we previously allocated.
* @see IWorkbenchWindowActionDelegate#dispose
*/
public void dispose() {
}

/**
* We will cache window object in order to
* be able to provide parent shell for the message dialog.
* @see IWorkbenchWindowActionDelegate#init
*/
public void init(IWorkbenchWindow window) {
this.window = window;
}
}

这是一个关于用Diglog类的例子,各个方面已经讲解得很清楚了,大家可以参考一下.有不明白的地方,可以留言给我
