JComboBox link

Question

Hello,
new in Java and JDeveloper..
2 questions (basics...) and I hope clear (Jclient) :
1)
I have a panel with a jcombobox (a username from the raf_util table)) :
jComboBox1.setModel(JUComboBoxBinding.createLovBinding(panelBinding, jComboBox1, "RafTicketView1", null, "RafTicketView1Iter", new String[] {"CodeUtilApp"}, "RAfUtilAppView1", new String[] {"Username"}, new String[] {"Username"}, null, null));
jComboBox1.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
jComboBox1_actionPerformed(e);
The Username is an attribute from an EO and View (BC4J) - created from the table RAF_Ticket :
SQL> desc raf_ticket;
Nom NULL ? Type
NO_TICKET NOT NULL NUMBER(6)
HORODATE NOT NULL DATE
CODE_UTIL_APP NOT NULL VARCHAR2(30)
CODAGENC NOT NULL NUMBER(6)
DESCR_PB NOT NULL VARCHAR2(30)
CODE_UTIL_INTERV0 NOT NULL VARCHAR2(30)
CODE_UTIL_INTERV1 VARCHAR2(30)
REF_DOSS NOT NULL VARCHAR2(20)
CODE_ACT NOT NULL VARCHAR2(2)
NIV_URG NOT NULL NUMBER(2)
TOP_DOS_UT VARCHAR2(1)
DESCR_LIBRE VARCHAR2(1500)
DATE_DEB_PREV DATE
DATE_FIN_PREV DATE
DFP_NEGOC VARCHAR2(1)
CHARGE_PREV DATE
DATE_DEB_INTERV DATE
DATE_DERN_INTERV DATE
DATE_CLOT DATE
MOTIF_CLOT NUMBER(2)
DATE_VAL_UTIL DATE
TICKET_REF NUMBER(6)
PROJET_REF VARCHAR2(30)
I have below the jcombobox 2 Jtextfields where I want to put wordings for agency (LIBAGENCE) and company (LIBSOCIE) which belongs to these tables :
SQL> desc raf_AG;
Nom NULL ? Type
CODAGENC NOT NULL NUMBER(6)
LIBAGENCE NOT NULL VARCHAR2(40)
CODREGIO NOT NULL VARCHAR2(3)
CODSOCIE NOT NULL VARCHAR2(3)
USERCREAT VARCHAR2(30)
DATECREAT DATE
USERMODIF VARCHAR2(30)
DATEMODIF DATE
SQL> desc raf_soci;
Nom NULL ? Type
CODSOCIE NOT NULL VARCHAR2(3)
LIBSOCIE NOT NULL VARCHAR2(40)
ADRESSE1 VARCHAR2(40)
ADRESSE2 VARCHAR2(40)
CODPOSTA NUMBER(5)
LIBVILLE VARCHAR2(40)
SQL> desc raf_util;
Nom NULL ? Type
USERNAME NOT NULL VARCHAR2(30)
USER_ID NOT NULL NUMBER(3)
CODAGENC NOT NULL NUMBER(6)
TYPE_UTIL VARCHAR2(1)
The relation between them is in Sql :
"select libagence, libsocie from raf_util, raf_ag, raf_soci where raf_util.codagenc=raf_ag.CODAGENC and raf_ag.CODSOCIE=raf_soci.CODSOCIE and raf_util.username= ?";
? = the data selected in the jcombobox.
do I have to write code for this. If yes, is the private void jComboBox1_actionPerformed(ActionEvent e), the right method?
How can i get the selected data from the jcombobox to pass it to the Sql parameter? I have tried
String strSelItem = jComboBox1.getSelectedItem().toString(); but it seems that It is not the right way.
And the first time, when I enter in the form, how to make the first value "selected" from the jcombobox?
Or could I put some automatic links between the 3 fields (BC4J, View, Module) in the document inspector properties for the 2 Jtextfield? so that when I choose a username, the 2 fields will display automatically the wordings.
2) this form could be called from a "RootForm" (menu) in various manners. today :
private void jButton8_actionPerformed(ActionEvent e)
JUApplication app = panelBinding.getApplication();
if (app.findFormBinding(TICKET) == null)
// instead of 'ordersPanelBinding.setApplication(app)', register
// the panelBinding under an explicit key
app.addFormBinding(TICKET, TicketPanelBinding);
TicketForm.setPanelBinding(TicketPanelBinding);
TicketPanelBinding.execute();
TicketForm.setVisible(true);
else
TicketForm.setVisible(true);
Depending on these various call (Jbutton), I want to do different treatments in the Panelview.java for Ticket.
How can I pass parameters from the menu to the form ?
Instructions?
Thanks and best regards.

Answer 1

frank,
1) yes, that's it. the combo box selection just query existing records (UI Editor - property inspector - model - Jclient LOV Binding). How to get the field selected in my form program (java class) or is it possible automatically ?
2) Yes, I have differents Jbutton in the menu. They action is to call the same form but with a parameter so that I can put different controls in the form depending on this parameter received. Basic but I don't know how to do that with java and jdev.
3) how to select a data in the jcombobox by default ?
