java - ListSelectionModel and listener -


i've jtable listselectionmodel , listselectionlistener.

the selection model set in jtables constructor: lsm.getselectionmodel()

and listselectionlistener set via public method:

    public void setlistselectionlistener(listselectionlistener l){         lsm.addlistselectionlistener(l);     }

called controller class:

    view.settableselectionlistener(new listselectionlistener(){         @override         public void valuechanged(listselectionevent e){             if (!e.getvalueisadjusting()) {                 int viewrow = e.getfirstindex();                 system.out.println(viewrow + " selected");                               }         }     });

because listener created in class can't use jtable's getselectedrow(); method, using listselectionevent object's getfirstindex(); doesn't current selection.

so i'm using int viewrow = ((listselectionmodel)e.getsource()).getleadselectionindex());

does seem correct way current selection? seems working, i'm not sure if bad way of doing it. thanks

only getminselectionindex() , getmaxselectionindex() works, returns min , max of selected indices respectively. lead/anchor selected index may >= 0 when there no selected row.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
