JButtons in JTable cell change shape on row selection
I have a single cell (column) per row based table and the cell is a panel with 2 buttons on it. TableCellRenderer and TableCellEditor are implemented correctly to allow render and edit the cell. But when i click the row or even the button, the shape of the buttons change. It looks like the size of the button shrinks to fit the button text. Please see the attached images.
If I set a preferred size of the buttons then the size doesn't seem to change but the button text shift towards right. Below is the code of the table cell panel. Running this panel from a main in the same class like shown below dosn't show this behavior. This behavior is only visible when using this panel as a cell in the single column table row. Don't know which property of what to set/change.

Adding a sample code to help reproduce the problem. Run the main in the NewJFrame1 class to see the issue. Uncomment and Run the main in the TableRowPanel1 private class to see the default correct working. If i use the table cell panel component directly in a JFrame it works fine. But same component used as table cell via an editor shows the problem. Really need help with this please.:

Solution
According to the source code, the border inset of the table cell editor is 0 according to the FlatBorder specification.
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)
Any ideas about how to rectify this?
Make the cell editor panel hierarchy three or more levels.
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);
}
}
or override FlatBorder#isCellEditor(Component c) method to always return 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);
