Force stop edit cell in JTable on mouse click - swing

Question

How to force stop editing a cell in a JTable when the user clicks on any other component than the table itself?
Tried this but it didn't work...
myTable.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
... or this, which also does not work as expected
Component co = myTable.getEditorComponent();
if (co != null && !(co instanceof JComboBox)) {
co.addFocusListener(new java.awt.event.FocusAdapter() {
public void focusLost(java.awt.event.FocusEvent evt) {
TableCellEditor tce = myTable.getCellEditor();
if (tce != null) {
tce.stopCellEditing(); // should accept partial edit
}
}
});
}
Having a button with an action listener attached to it makes it possible to force stop editing of any cell in the table, however that's not really the solution I am looking for.
It should work by clicking on any component.

The table does not take up all the space in the viewport of the scrollpane so you are actually clicking on the viewport. By default a viewport doesn't gain focus when you click on it so there is no focusLost method generated on the table.
Maybe you can just use the following so the table fills the viewport:
table.setFillsViewportHeight(true);
Otherwise, you would need to add a MouseListener to the viewport to handle the mouse click event. You would need to do this for all components on the frame that cannot receive focus, like a JPanel.
Or, maybe another approach is to use an AWTEventListener to listen for all mouse clicks. The draw back to this approach is that you can't distinguish between a click on a focusable component and a non-focusable component so you would be attempting to stop the cell editing every time a click is made. See Global Event Listeners for more information.
