Wow, JavaFX tables are WAY easier to use than Swing tables. I remember my first time messing with them. I spent like 4 hours trying to make it all work.
All of these tutorials helped so much, easy to follow, informative and you are a good teacher! plus i get a pretty good laugh when you go off track talking about things haha thank you so much man!
Searched google for an hour....Didn't get the concept. After your tutorial I checked the concept behind data model and TableView and I could implement one table on my own. THANKS! :)
How come the quantity column sorts like an integer column (11:02) while the data type of the column is actually (accidentally) set to String? I would expect the sorted order to be like "12", "198", "20", "74", "856". (Now I also wonder how a column would sort if the data type is not Comparable)
In the Production class,the type of the quantity is an int,but why in the instruction: TableColumn QuantityColumn=new TableColumn("Quantity"); the type you've used isn't Intégrer?
Generic classes in Java do not accept primitive data types in their type arguments. Hence, the int in Product class will automatically be promoted to Integer.
@Rohit Awate. "Generic classes in Java do not accept primitive data types in their type arguments. Hence, the int in Product class will automatically be promoted to Integer." do you mean since int is an primitive type argument, it cannot be passed into a function? then why "Integer" will be accepted? aren't int and Integer the same thing?
I tried to follow the tutorial and the source-code on Buckys website but I cannot compile. I have the following error:" Main18.java:62: error: cannot find symbol ObservableList products = FXCollecions.observableArrayList(); " but I am sure I have already imported FXCollections at the top. why is this? at the top of my Main.java: "import javafx.collections.FXCollections;"
Hi, I'm doing these, and I get to the " nameColumn.setCellFactory(new PropertyValueFactory("name"));" part, but I'm using SDK 15 and I get an error in the part of the code.
Hey! What if I have an Array or an ArrayList of float data in the product class? How can I fill a cell of the column with a number that is contained in an Array?
How about sir more than one table query to display on tableview? Do i have to create tablecolumn and class model? Such as a query of one patient has lots of visits query.
@edit now i get it.. get function must be like getPytanie not like i had getpytanie.. ^^ one small letter big difference ehh meh i tried this and it shows me right colums but values are empty.. ObservableList lista_danych = FXCollections.observableArrayList(lista_pytan); lista_pytan is my ArrayList with Szablon_bazy objects.. i ve 30 objects there and when i show TableView its even show 30 rows but all are empty.. ObservableList has this elements, i just tried to print them with foreach. I ve no idea why table wont show me them..
This may be too late for you but in case someone else is wondering: Lists and such can't have primitive types (so no List, , , etc! google primitive types if you don't understand), because the List methods are defined to receive Objects. To work around this, there's this thing called "wrappers", which are classes dedicated to each of the 8 primitive data types. These wrappers basically transform the primitive variable/value into an object so it can be passed around as one. The wrapper for doubles is Double, so you write "List". Hope it helps someone, for a more detailed explanation, google "Java wrappers".
in my Product class, i've placed a Supplier object as one of the product's properties. in the table i want to show the supplier's name, how would i do that without changing the getSupplier method?
How do I do this with user input into an ArrayList e.g. Enter name, enter account number and enter balance. Like how would I get the data to show in the TableView?
Might be late, but you'd need to use a printer API for that. I don't think JavaFX has built in functionality for printing out to a printer. I'd look up "Java printer API" and see what you get.
The < and > are called chevrons. Yes, like the gas station. If you look at their logo, it even has 2 chevrons in it. A chevron is also the black and yellow signs with multiple repeating arrows pointing to the direction of the flow of traffic (see example here ). Lastly, it is the shape of the back legs of goats and dear.
Hey guys i've copy pasted the code from the gitHub since my orignal written code didnt run, but the codes from gitHub also didnt run. Both had no error whatsoever. Any idea why?
How does PropertyValueFactory() know how to get the specified values? I don't see how just putting "name" helps the compiler know where to get the info D: or could it be that it all happens at table.setItems(getProduct()); and the ObservableList organizes the data in a manner such that the variable (field) 'name' in the Product class is passed as a "string" or a property name somewhat similar to how JSON works and at the end uses something like a JSON.parse() to convert and get the values?
SIR! HOW TO MAKE A SAME PROGRAM WITH ADD BUTTON WHERE YOU CAN ADD DATA YOU WANT AND THE TABLE COLUMN IS AUTO GENERATED (SO IT MEANS THAT IF THERE IS NO DATA THERE'S ALSO NO TABLE COLUMN) THANKS HOPE YOU NOTICE I REALLY NEED ANSWER
how to populate table with arraylist of primitive type of data? what should be inside of >>> Tablenumber.cellValueFactoryProperty(new PropertyValueFactory();
The FXCollections class has static methods where you can pass in a Collection object to create an Observable with that Collection's data. I don't remember seeing one where you could pass in an array, but you can convert an array into a Collection pretty simply as well.
For some reason my code it's not showing the quantity(in my case inventory) in the table. //Main.java public class Main extends Application{ Stage window; Scene scene1,scene2; VBox panel; TableView table; public static void main(String[] args){ launch(args); } @Override public void start(Stage stage) throws Exception { window = stage; window.setTitle("Aplicacion de Prueba - Alejandro Rodriguez"); TableColumn name_c = new TableColumn("Resource Name"); name_c.setMinWidth(200); name_c.setCellValueFactory( new PropertyValueFactory("Name")); TableColumn price_c = new TableColumn("Resource Price"); price_c.setMinWidth(125); price_c.setCellValueFactory( new PropertyValueFactory("Price")); TableColumn inventory_c = new TableColumn("Resource Inventory"); inventory_c.setMinWidth(125); inventory_c.setCellValueFactory( new PropertyValueFactory("Inventory")); table = new TableView(); table.getColumns().addAll(name_c, price_c, inventory_c); table.setItems(getResources()); panel = new VBox(); panel.getChildren().add(table); // Scene Scene scene = new Scene(panel,500,250); window.setScene(scene); window.show(); } public ObservableList getResources(){ ObservableList res = FXCollections.observableArrayList(); res.add( new Resources("Wood", 9.99, 100)); res.add( new Resources("Iron", 12.85, 70)); res.add( new Resources("Cotton", 3.16, 200)); res.add( new Resources("Marble", 20.75, 50)); res.add( new Resources("Glass", 5.99, 175)); return res; } //Resources.java public class Resources { private String name; private double price; private int inventory; public Resources(){ this.name = ""; this.price = 0; this.inventory = 0; } public Resources(String n,double p,int i){ this.name = n; this.price = p; this.inventory = i; } public String getName() { return name; } public void setName(String nm) { this.name = nm; } public double getPrice() { return price; } public void setPrice(double pr) { this.price = pr; } public int getInvetory() { System.out.println(inventory); return inventory; } public void setInvetory(int inv) { this.inventory = inv; } }

csandreas1 The syntax is similar, but both programming languages are different enough to have their own room. For Example: Java does use a GarbageCollector. C++ does not. C++ classes mostly do need a destructor method, because there is no GarbageCollector. Java code is compiled into Java ByteCode, this code does run everywhere, where a Java Virtual Machine does run. C++ code is compiled natively, its compiled binary does run directly on the systems CPU architecture and must be recompiled for other CPU architectures. You can't use the same compiled binarys on all CPU architectures. That's one of the reasons why C++ is known as a system programming language. You wouldn't use Java as a system programming language. Java has a great standard library. The standard library from C++ is much smaller, which means, that you normally use 3rd party librarys in the C++ world or write everything on your own, which results in extra work. But all in all, they differ so much, that you won't use only one of those languages. If you take programming seriously, you will learn both of them. The choice for the one or the other language really depends on what software you are planing to write. The workload is also not the same. To programme an application where both languages are suitable for, programming it in Java, means that Java will often require you to invest less time into the programming to get the application done. C++ on the other side is much more expressive. The same task can be done very differently and with C++ you will more likely shoot yourself in the foot, but if performance is very important, C++ is in most times the way to go. But this does not mean, that Java would be slow. Its performance is good enough for most of the appilcations you might want to write.
Awesome tutorial Man, I cringe at these so called "real languages" when it comes to desktop apps and GUIs. App development must take decades lol. I'll use VBA, build a fully functional UI, connect to a database, and jam the data into the UI in about 20 lines of code lol

They aren't, you should read about unboxing and autoboxing in java.

I wonder how you get the private properties of the Product class in the table by using the "name" of the property without invoking the getters ?
Actually it is dependent on the getter. it gotta be (get + attribute with capitalized first letter). Otherwise you would get an Exception
