Dialog control field event

1. Use the info() method to info the control field's name.

protected Object dialog(DialogRunbase _dialog, boolean forceOnClient)
{
    ;

    dialog = super(_dialog, forceOnClient);

    dlg_field1 = dialog.addFieldValue(Types::String, g_Value);

    info(dlg_field1.name()); //The name is 'fld1_1'.

    ....
}

2. Add a method to active the custom event mode.

public void dialogPostRun(DialogRunbase _dialog)
{
    ;

    super(_dialog);

    _dialog.dialogForm().formRun().controlMethodOverload(true);
    _dialog.dialogForm().formRun().controlMethodOverloadObject(this);
}

3. Add a new event method, in current case we add a modified event. The event name format must be "Field name + Event name", such as 'fld1_1_modifed'.

public boolean fld1_1_modified()
{
    FormStringControl   control;
    boolean             ret;
    str                 tmp;
    ;

    control = dialog.formRun().controlCallingMethod();

    ret = control.modified();

    if (ret)
    {
        if (!dlg_MailToLong.value())
            dlg_MailToLong.value(dlg_MailTo.value());
        else
        {
            tmp = dlg_MailToLong.value() + "," + dlg_MailTo.value();
            dlg_MailToLong.value(tmp);
        }

        dlg_MailTo.value("");
    }

    return ret;
}
