swing - Java GUI JButton to actionlistner -

i have made gui in netbeans. it's chat programme , have 4 commandos /join, /leave, /whisper , /leave

private void commandoactionperformed(java.awt.event.actionevent evt) { joptionpane.showmessagedialog(rootpane, "the next commandos are:" + "\n" + "\n" + "/join channel name" + "\n" + "/leave channel name" + "\n" + "/whisper nick message" + "\n" + "/quit - quit program"); }

and ok, want actionlister instead of showmessagedialog can force on of them , comes in jtextfield. think can them there don't know how actionlistener combined this.

edit: want force commando button , windows have 4 new buttons, each 1 commando (/join, /leave, /whisper , /exit) when force 1 of these buttons commando in text field need write rest. if force "/join" button, need write channel name.

edit2: if pretty bad in describing problem, can show wanted , have done far:

private void showcommandactionperformed(java.awt.event.actionevent evt) { object[] options = { "/join", "/leave", "/whisper", "/quit", "ingenting" }; int choice= joptionpane.showoptiondialog(rootpane, "what u want do? ", null, width, width, null, options, rootpane); switch (choice) { case 0: skrivtekst.settext("/join "); skrivtekst.requestfocus(); break; case 1: skrivtekst.settext("/leave"); skrivtekst.requestfocus(); break; case 2: skrivtekst.settext("/whisper"); skrivtekst.requestfocus(); break; case 3: skrivtekst.settext("/join "); skrivtekst.requestfocus(); case 4: system.exit(1); //this wrong. want close window, not whole programme default: joptionpane.showmessagedialog(null, "donno what!?!?!?!?!?!?!" + choice); } }

i hope show wanted , have done. ty :) problem have left closing 1 joptionpane window , not program

1) can implements jradiobuttons in buttongroup, 1 of choices available selection, there can implelements actionlistener, , within actionlistener settext() jtextfield

2) please utilize standard swing jcomponents rather prepared components palette, hard override basic swing methods
