用户界面Java GUI GridBagLayout如何在一列中容纳三个组合框？

Question

我正在使用Eclipse，用Java编程，在学校项目中使用GridBagLayout manager

目前看来是这样的

我想把三个组合框（MM，DD，YYYY）放在一列中（与accNoT和其他组合框对齐），但我不知道怎么做 我试图修补weightx或weighty，但我什么也没做

这是该部分的代码

c.fill = GridBagConstraints.HORIZONTAL;
//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 0;
c.ipadx = 50;
pane.add(accNoT, c);

c.fill = GridBagConstraints.HORIZONTAL;
//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 1;
pane.add(cellNoT, c);



c.fill = GridBagConstraints.HORIZONTAL;
c.weighty = 0.3;
c.gridx = 1;
c.gridy = 2;
pane.add(monthBox, c);

c.fill = GridBagConstraints.HORIZONTAL;
c.weighty = 0.3;

c.gridx = 2;
c.gridy = 2;
pane.add(dayBox, c);

c.fill = GridBagConstraints.HORIZONTAL;
c.weighty = 0.3;
c.gridx = 3;
c.gridy = 2;
pane.add(yearBox, c);

c.fill = GridBagConstraints.HORIZONTAL;
//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 3;
pane.add(planList, c);

我在图片中添加了一些文字，这样就不会有点混乱了 另外，我正在关注https://docs.oracle.com/javase/tutorial/uiswing/layout/gridbag.html 我只是修改了他们的例子

到目前为止，除了试图找出权重x和y之外，我还做了些什么，到目前为止我还不明白 我将DD和YYYY组合框放在不同的列中 然后我将一些gridWidth设置为accNoT等于2，但它不起作用，DD只是消失了

回答：非常感谢用户85421//////

正如user85421在评论中所说，添加gridwidth 三个组合框应该是1，其余的应该是3

代码

  c.fill = GridBagConstraints.HORIZONTAL;

//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 0;
c.ipadx = 50;
c.gridwidth = 3;
pane.add(accNoT, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 1;
c.gridwidth = 3;

pane.add(cellNoT, c);



c.fill = GridBagConstraints.HORIZONTAL;


c.gridx = 1;
c.gridy = 2;
c.gridwidth = 1;

pane.add(monthBox, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weighty = 0.3;

c.gridx = 2;
c.gridy = 2;
c.gridwidth = 1;
pane.add(dayBox, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weighty = 0.3;
c.gridx = 3;
c.gridy = 2;
c.gridwidth = 1;
pane.add(yearBox, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 3;
c.gridwidth = 3;
pane.add(planList, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 4;
c.gridwidth = 3;
pane.add(adjT, c);

c.fill = GridBagConstraints.HORIZONTAL;

//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 5;
c.gridwidth = 3;
pane.add(eUsageT, c);

c.fill = GridBagConstraints.HORIZONTAL;
//c.weightx = 0.5;
c.gridx = 1;
c.gridy = 6;
c.gridwidth = 3;
pane.add(prevBAT, c);

////THIRD COLUMN//////////////////////////////////////////
c.fill = GridBagConstraints.HORIZONTAL;
//c.weightx = 0.5;
c.gridx = 4;
c.gridy = 1;
c.gridwidth = 3;
pane.add(monPLR, c);

结果

是的，它看起来很可怕，但至少三个组合框适合一列

您可能会注意到在“第三列”部分 网格=4 这是因为yyy组合框的gridy=3
