如何在vaadin中关闭窗口?

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?

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.
