JAVA事件处理的常用写法

******事件处理的常用写法******

//内部匿名类
list.addSelectionListener(new SelectionListener(){
//程序代码
});

//内部类
SelctionListener listener = new SelctionListener(){
public void widgetSelected(SelectionEvent e){
}

public void widgetDefaultSelected(SelectionEvent e){
}
};

Button button = new Button(shell,SWT.NONE);
button.addSelectionListener(listener);

//list.addSelectionListener(listener);
//list.removeSelectionListener(listener);

//实现接口的类
public class MyListener implements SelectionListener{
public void widgetSelected(SelectionEvent e){}
public void widgetDefaultSelected(SelectionEvent e){}

};

Button button = new Button(shell,SWT.NONE);
button.addSelectionListener(new MyListener());

//继承的类的方法
public class MyAdapter extends SelectionAapter{
public void widgetSelected(SelectionEvent e){
}
public void widgetDefaultSelected(SelectionEvent e){
}
};

Button button = new Button(shell,SWT.NONE);
button.addSelectionListener(new MyAdapter());
