看了AnchorLayout布局,发现它是一个很不错的布局,但是遇到个问题,看代码先。
import com.cloudgarden.layout.AnchorConstraint;
import com.cloudgarden.layout.AnchorLayout;
import Javax.swing.JPanel;
import javax.swing.WindowConstants;
import javax.swing.SwingUtilities;
public class NewJFrame extends javax.swing.JFrame {
private JPanel jPanel4;
private JPanel jPanel1;
/**
* Auto-generated main method to display this JFrame
*/
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
NewJFrame inst = new NewJFrame();
inst.setLocationRelativeTo(null);
inst.setVisible(true);
}
});
}
public NewJFrame() {
super();
initGUI();
}
private void initGUI() {
try {
AnchorLayout thisLayout = new AnchorLayout();
getContentPane().setLayout(thisLayout);
setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
{
jPanel1 = new JPanel();
getContentPane().add(jPanel1, new AnchorConstraint(1, 905, 1001, 0, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL, AnchorConstraint.ANCHOR_REL));
jPanel1.setPreferredSize(new java.awt.Dimension(557, 330));
}
pack();
this.setSize(400, 400);
} catch (Exception e) {
//add your error handling code here
e.printStackTrace();
}
}
}
红色部分数字为编辑区域的千分比,后面的 AnchorConstraint.ANCHOR_REL、AnchorConstraint.ANCHOR_ABS、AnchorConstraint.ANCHOR_NONE分别为相对、绝对、没有(这个是猜的)位置,分别对应前面的数字。
