我想使用GridBagLayout在Java中创建GUI。这就是我最终想要的:
因此,我遵循了我在互联网上找到的一些说明,这是我写的代码:
Panel panel = new Panel();
panel.setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
gc.fill = GridBagConstraints.BOTH;
gc.insets = new Insets(5, 5, 5, 5);
gc.weightx = 7;
gc.weighty = 7;
panel.add(new JLabel("title"), gc, 0, 0, 2, 1);
panel.add(new JButton("button 1"), gc, 2, 0, 1, 1);
panel.add(new JButton("button 2"), gc, 3, 0, 1, 1);
panel.add(new JButton("button 3"), gc, 4, 0, 1, 1);
panel.add(new JButton("button 4"), gc, 5, 0, 1, 1);
panel.add(new JButton("button 5"), gc, 6, 0, 1, 1);
panel.add(new JLabel("subtitle"), gc, 0, 1, 7, 1);
panel.add(new JButton("list"), gc, 0, 2, 2, 4);
panel.add(new JButton("button"), gc, 0, 6, 1, 1);
panel.add(new JButton("button"), gc, 1, 6, 1, 1);
panel.add(new JButton("table"), gc, 2, 2, 5, 5);
我的功能添加:
public void add(Component component, GridBagConstraints constraints, int x, int y, int width, int height) {
constraints.gridx = x;
constraints.gridy = y;
constraints.gridwidth = width;
constraints.gridheight = height;
this.add(component, constraints);
}
但是,最后我有这个:
如您所见,该表根本不占用5个单元格,并且该列表不占用4个单元格。有谁知道它为什么会这样?谢谢。
答案 0 :(得分:1)
如果添加:
,它应该有用 constraints.weightx = (double) width / 7.0;
constraints.weighty = (double) height / 7.0;
添加方法。
