0java结构办理器-borderlayout

0安装NetBeans IDE 8.1

0iReport安装java打印

工具/原料

  • netbeans
  • java

方式/步骤

  1. 1

    新建一个java项目。

    0java结构办理器-borderlayout

  2. 2

    新建一个类，取名jframe2。

  3. 3

    打开jframe2.java这个文件，把代码点窜为：

    public class jframe2 extends javax.swing.JFrame{

        public jframe2(){

            buju();

        }

        private void buju(){

       

        }

        public static void main(String[] arg){

        }

    }

  4. 4

    界说用到的变量。

  5. 5

    在buju这个方式中初始化变量：new 类。

  6. 6

    关头代码：

    this.getContentPane().setLayout(new java.awt.GridBagLayout());

    窗口结构设为GridBagLayout

    gridBagConstraints.gridx = 0;结构0列

    gridBagConstraints.gridy = 0;结构0行

    gridBagConstraints.gridwidth=1;     几多列

    gridBagConstraints.gridheight=1;    几多行

    gridBagConstraints.weightx=1;   分派程度空间

    gridBagConstraints.weighty=1;    分派垂直空间

    gridBagConstraints.fill=java.awt.GridBagConstraints.HORIZONTAL填充，程度，垂直，

    gridBagConstraints.insets = new java.awt.Insets(5, 5, 5, 5);外侧空间

  7. 7

    buju方式中完整代码：

     java.awt.GridBagConstraints gridBagConstraints;

    添加main方式中代码：

    java.awt.EventQueue.invokeLater(new Runnable(){

                @Override

                public void run(){

                    new jframe2().setVisible(true);

                }

            });
