如何解决JTable 单元格中的 JButtons 在行选择时改变形状
我的每行表格都有一个单元格（列），该单元格是一个面板，上面有 2 个按钮。 TableCellRenderer 和 TableCellEditor 已正确实现以允许渲染和编辑单元格。但是当我单击行甚至按钮时，按钮的形状会发生变化。看起来按钮的大小缩小以适应按钮文本。请参阅所附图片。
如果我设置了按钮的首选大小，那么大小似乎没有改变，但按钮文本向右移动。下面是表格单元格面板的代码。从同一个类中的 main 运行此面板，如下所示，不会显示此行为。此行为仅在将此面板用作单列表格行中的单元格时才可见。不知道要设置/更改什么属性。

// infoButton.putClientProperty("JButton.buttonType","roundRect");
// scanButton.putClientProperty("JButton.buttonType","roundRect");
//
// infoButton.addActionListener((e) -> {
// log.info("info clicked");
// });

添加示例代码以帮助重现问题。运行 NewJFrame1 类中的 main 以查看问题。取消注释并运行 TableRowPanel1 私有类中的 main 以查看默认的正确工作。如果我直接在 JFrame 中使用表格单元格面板组件，它工作正常。但是通过编辑器用作表格单元的相同组件显示了问题。真的需要这方面的帮助。：

解决方法
根据源代码，根据FlatBorder规范，表格单元格编辑器的边框插入为0。
com/formdev/flatlaf/ui/FlatBorder.java
protected boolean isCellEditor( Component c ) {
return FlatUIUtils.isCellEditor( c );
}
@Override
public Insets getBorderInsets( Component c,Insets insets ) {
// ...
if( isCellEditor( c ) ) {
// remove top and bottom insets if used as cell editor
insets.top = insets.bottom = 0;
// ...
com/formdev/flatlaf/ui/FlatUIUtils.java
public static boolean isCellEditor( Component c ) {
// check whether used in cell editor (check 3 levels up)
关于如何纠正这个问题有什么想法吗？
将单元格编辑器面板的层次结构设为三个或更多级别。
class TableRowPanel1 extends JPanel {
protected final JButton jButton1 = new JButton("jButton1");
protected final JButton jButton2 = new JButton("jButton2");
public TableRowPanel1() {
super(new BorderLayout());
JPanel p2 = new JPanel(new FlowLayout(FlowLayout.LEADING));
p2.add(jButton1);
p2.add(jButton2);
JPanel p1 = new JPanel(new BorderLayout());
p1.add(p2);
add(p1);
}
}
或覆盖 FlatBorder#isCellEditor(Component c) 方法以始终返回 false。
class TableRowPanel1 extends JPanel {
protected final JButton jButton1 = new JButton("jButton1");
protected final JButton jButton2 = new JButton("jButton2");
public TableRowPanel1() {
super(new FlowLayout(FlowLayout.LEADING));
FlatBorder border = new FlatButtonBorder() {
@Override protected boolean isCellEditor(Component c) {
return false;
}
};
jButton1.setBorder(border);
jButton2.setBorder(border);
add(jButton1);
add(jButton2);
}
}
