如何在vaadin中关闭窗口? [英] How to close window in vaadin?

问题描述

我有类 MyCustomWindow，它从 vaadin 扩展了 Window (com.vaadin.ui).当您单击某个按钮时，MyCustomWindow 将显示.现在我想向这个窗口添加按钮，当你按下这个按钮时，它会关闭窗口.我有问题要使用什么来删除此窗口.我发现:

I have got class MyCustomWindow which extends Window (com.vaadin.ui) from vaadin. When you click some button MyCustomWindow will show. Now I would like to add button to this window and when you push this buton it will close the window. I have got problem what to use to remove this window. I have found:

Window w = getWindow();
getApplication().removeWindow(w);

或

Window w = this.findAncestor(Window.class);
w.close();

但它不起作用.我想使用this"从班级内部而不是外部移除窗口?类似的东西:

But it doesn't work. I would like to remove window from inside the class, not from outside, using "this"? Something like:

UI.getCurrent().removeWindow(this);

我正在使用 vaadin 7.你能帮我吗?

I am using vaadin 7. Can you help me?

推荐答案

您好，如果您想从单击侦听器内部关闭窗口，您可以执行以下两项操作之一:

Hello if you want to close the window from inside your click listener you can do one of the following two things:

yourButton.addClickListener(new Button.ClickListener() {
            @Override
            public void buttonClick(Button.ClickEvent event) {
                MyCustomWindow.this.close();
            }
        });

或者:

yourButton.addClickListener(new Button.ClickListener() {
            @Override
            public void buttonClick(Button.ClickEvent event) {
                closeMyCustomWindow();
            }
        });

private void closeMyCustomWindow(){
   this.close();
}

closeMyCustomWindow() 这个函数在 MyCustomWindow 类中.

closeMyCustomWindow() this function is inside the MyCustomWindow class.
