How to identify certain action from multiple sub-panels...

801416 Dec 20, 2010 1:16 PM

Hello everyone,
I'm new to Swing... and I desperately need help...
I have ‘n’ numbers of JPanel. And each panel contains certain number of sub-panels. Those sub-panels have actionlisteners. How can I identify which sub-panel fire an action?
For example –
Panel_1 => sub_1, sub_2, sub_3
Panel_2 => sub_1, sub_2, sub_3
Panel_n => sub_1, sub_2, sub_3
Note that ‘n’ is unknown and main panels will be created dynamically. Now, if I attach actionListener with all of those sub_panels, how would I be able to figure out which sub_panel fires that action and thatsub-panel belongs to which main panel? In other words, if, sub_2 fires an action, how can I figure out that sub_2 belongs to which main panel?
Please help me.

Use your action event getSource() method/

I know that I can use getSource() method to identify action event... but how can I identify the main panel it belongs to?

what's wrong with getSource().getParent() ? (apart from the missing type cast, obviously ;-)

<tt>JPanel</tt>s can't have <tt>ActionListeners</tt>. What class of GUI component are you really talking about?

when I said sub-panels, I meant Jtextfield, Jcombobox.
