目前我想使用带有gridbaglayout的JPanel来显示表结构,但我在设计时遇到了一些麻烦。
我的数据存储在节点结构中(从xml文档解析)。在我的代码中,如果节点有一组其他节点(递归方法showGroupField),我每次都会创建一个新面板。我还有一个创建gridbagconstraint的方法,它给了我一个表结构。问题是当一个新面板添加到主面板时,它会粘贴在gridbaglayout的第一列,而不是使用主面板的整个宽度。有谁知道如何解决这个问题?非常感谢!
这就是我现在所拥有的:
这就是我想要的:
代码:
package view;
import domain.NodeInfo;
public class InputScreen {
...
public InputScreen(Node parentNode){
this.parentNode = parentNode;
nodeInfo = new NodeInfo();
}
public void initiateInputScreen() {
mainFrame = new JFrame("Front-End Generator");
mainFrame.setSize(1000,1000);
contentPanel = new JPanel();
inputPanel = new JPanel();
makeContentPanel();
mainFrame.setContentPane(contentPanel);
mainFrame.pack();
mainFrame.setLocationRelativeTo(null);
mainFrame.setVisible(true);
mainFrame.setResizable(false);
}
private void makeContentPanel() {
contentPanel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
contentPanel.setLayout(new BorderLayout(5,5));
makeInputPanel();
contentPanel.add(inputPanel, BorderLayout.CENTER);
}
private void makeInputPanel() {
inputPanel.setBorder(BorderFactory.createTitledBorder("Inputs"));
inputPanel.setLayout(new GridBagLayout());
inputPanel.add(new JLabel(nodeInfo.getNodeInformation(parentNode)), createGbc(0, 0));
inputPanel.add(showGroupField(parentNode.getFirstChild()), createGbc(0,1));
}
private JPanel showGroupField(Node node) {
int count = 0;
JPanel tmpPanel = new JPanel(new GridBagLayout());
tmpPanel.setBorder(BorderFactory.createTitledBorder("Test"));
NodeList listNode = node.getChildNodes();
for(int i=0; i<listNode.getLength(); i++){
if(nodeInfo.isGroupField(listNode.item(i))){
tmpPanel.add(showGroupField(listNode.item(i)), createGbc(0, count));
count++;
}else{
tmpPanel.add(new JLabel("Test"), createGbc(0, count));
tmpPanel.add(new JTextField(20), createGbc(1, count));
count++;
}
}
return tmpPanel;
}
private GridBagConstraints createGbc(int x, int y){
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = x;
gbc.gridy = y;
gbc.gridwidth = 1;
gbc.gridheight = 1;
gbc.anchor = (x==0) ? GridBagConstraints.WEST : GridBagConstraints.EAST;
gbc.fill = (x==0) ? GridBagConstraints.BOTH : GridBagConstraints.HORIZONTAL;
gbc.insets = (x==0) ? new Insets(5,0,5,5) : new Insets(5,5,5,0);
gbc.weightx = (x==0) ? 0.1 : 1.0;
gbc.weighty = 1.0;
return gbc;
}
}
答案 0 :(得分:0)
尝试将inputPanel
添加到WEST
位置。
contentPanel.add(inputPanel, BorderLayout.WEST);
