How to set value to cell in TableView in javafx - javafx

Question

I am newbie on javafx. I already code in core java to set value to table. But now i am converting my project in javafx to maintain code and to improve design.
I am trying to set value to table view but i am not getting how to set value to tableview.
Here is my code which i am using for swing.
String testbedName = treePath.getPathComponent(1).toString();
TestBed currentTestbed = getTbF().get(testbedName);
propertyTable.getModel().setValueAt(currentTestbed.getTestBedName(), 0, 1);
propertyTable.getModel().setValueAt(currentTestbed.getTestBedFilePath() + "\\" + testbedName + ".xml", 1, 1);
propertyTable.getModel().setValueAt(currentTestbed.getTbElements().size(), 2, 1);
But i need to convert this code in javafx means from JTable to TableView. but tableview not find getModel() method.
I search but didn't get how to set value to table view.
Please give me reference or hint.
Thanks in advance.

Answer 1

In JavaFX you generally don't set the values cell by cell like that. In your case, for example, you would
place your TestBeds in the table:
TableView<TestBed> table = new TableView<>();
table.getItems().addAll(yourTestBeds);
you then create the columns you need, by providing appropriate cell value factories, for example (using Java 8 syntax):
TableColumn<TestBed, String> name = new TableColumn<>();
name.setCellValueFactory(c-> new SimpleStringProperty(c.getValue().getTestBedName()));
If you use Java 7:
name.setCellValueFactory(new Callback<CellDataFeatures<TestBed, String>, ObservableValue<String>>() {
#Override public ObservableValue<String> call(CellDataFeatures<TestBed, String> c) {
return new SimpleStringProperty(c.getValue().getTestBedName()));
}
});
Finally you add the columns to the table:
table.getColumns().addAll(name, someOtherColumn);

Suppose we have a table with two columns, one for a string, the other for a number. To set programmatically the i-th item or row of the table, we can do like this:
//Define the string
String s = "myString" ;
//Define the number
int value = 5;
//Synthesize the item = row
Item item = new Item(s, value);
//Set the i-th item
table.getItems().set(i, item);
