如何为Jlabel提供布局管理器？ [英] How Do I Give Jlabel A Layout Manager?

问题描述

如何为Jlable容器提供布局管理器？我尝试这样设置：

How do i give a Jlable container a layout manager? I tried to set it this way :

lab1=new JLabel(new GridLayout(1,1,15,15));

但它说这个构造函数是未定义的。任何人都可以帮我这个吗？

But it says this constructor is undefined. Can anyone help me with this?

推荐答案

下面的代码片段创建了GridLayout对象及其管理的组件。





GridLayout experimentLayout = new GridLayout（0,2）;



...



compsToExperiment.setLayout（experimentLayout）;



compsToExperiment.add（新JButton（按钮1））;

compsToExperiment.add（新JButton（按钮2））;

compsToExperiment.add（新JButton（按钮3））;

compsToExperiment.add （新JButton（长命名按钮4））;

compsToExperiment.add（新JButton（5））;



或



GridLayout experimentLayout = new GridLayout（0,2）;





compsToExperiment.setLayout（experimentLayout）;

lab1 = new JLabel（MyLabel）;

compsToExperiment.add（lab1）;

The code snippet below creates the GridLayout object and the components it manages.


GridLayout experimentLayout = new GridLayout(0,2);

...

compsToExperiment.setLayout(experimentLayout);

compsToExperiment.add(new JButton("Button 1"));
compsToExperiment.add(new JButton("Button 2"));
compsToExperiment.add(new JButton("Button 3"));
compsToExperiment.add(new JButton("Long-Named Button 4"));
compsToExperiment.add(new JButton("5"));

or

GridLayout experimentLayout = new GridLayout(0,2);


compsToExperiment.setLayout(experimentLayout);
lab1=new JLabel("MyLabel");
compsToExperiment.add(lab1);
