java - How to add checkboxes to JTABLE swing -


does know how put jcheckbox in jtable column? this:

table table tutorial

i took how use tables

thanks in advance.

1) jtable knows jcheckbox built-in boolean tablecellrenderers , tablecelleditor default, there contraproductive declare that,

2) abstracttablemodel should useful, in jtable required reduce/restrict/change nested , inherits methods default implemented in defaulttablemodel,

3) consider using defaulttablemodel, (if not sure how works) instead of abstracttablemodel,

table_with_booleantype_column

could generated simple code:

import javax.swing.*; import javax.swing.table.*;  public class tablecheckbox extends jframe {      private static final long serialversionuid = 1l;     private jtable table;      public tablecheckbox() {         object[] columnnames = {"type", "company", "shares", "price", "boolean"};         object[][] data = {             {"buy", "ibm", new integer(1000), new double(80.50), false},             {"sell", "microsoft", new integer(2000), new double(6.25), true},             {"sell", "apple", new integer(3000), new double(7.35), true},             {"buy", "nortel", new integer(4000), new double(20.00), false}         };         defaulttablemodel model = new defaulttablemodel(data, columnnames);         table = new jtable(model) {              private static final long serialversionuid = 1l;              /*@override             public class getcolumnclass(int column) {             return getvalueat(0, column).getclass();             }*/             @override             public class getcolumnclass(int column) {                 switch (column) {                     case 0:                         return string.class;                     case 1:                         return string.class;                     case 2:                         return integer.class;                     case 3:                         return double.class;                     default:                         return boolean.class;                 }             }         };         table.setpreferredscrollableviewportsize(table.getpreferredsize());         jscrollpane scrollpane = new jscrollpane(table);         getcontentpane().add(scrollpane);     }      public static void main(string[] args) {         swingutilities.invokelater(new runnable() {              @override             public void run() {                 tablecheckbox frame = new tablecheckbox();                 frame.setdefaultcloseoperation(exit_on_close);                 frame.pack();                 frame.setlocation(150, 150);                 frame.setvisible(true);             }         });     } }

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

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
