How to display matrix in JavaFX
I have two text fields and button. First one will have number of rows, second one will have number of columns. Button should create table with that numbers, then do some stuff with the elements of this table. Is there any analogue of GridView from C# for that? Because as I see I can't change number of rows in TableView and I think this will cause problem in future calculations. There is example from c#:
n = Int32.Parse(numericUpDown1.Text);
m = Int32.Parse(numericUpDown2.Text);
dataGridView1.RowCount = n;
dataGridView1.ColumnCount = m;
What can I use to do the same in Java?

Java Swing had a JTable. In Java FX that control is called TableView.
https://docs.oracle.com/javafx/2/ui_controls/table-view.htm
It's a pretty complicated control. You have to create a Table and then add 'column' objects to the table object like below:
DefaultTableModel tableModel = new DefaultTableModel();
javax.swing.JComboBox<Integer> jComboBoxRows = new javax.swing.JComboBox<>();
javax.swing.JComboBox<Integer> jComboBoxColumns = new javax.swing.JComboBox<>();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Simple JTable Example");
jComboBoxRows.setModel(new javax.swing.DefaultComboBoxModel<>(new Integer{1, 2, 3, 4}));
jTable1.setModel(tableModel);
jComboBoxRows.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent event) {
Integer tableRowValue = (Integer) jComboBoxRows.getSelectedItem();
tableModel.setNumRows(tableRowValue.intValue());
tableModel.fireTableDataChanged();
}
});
jComboBoxColumns.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent event) {
Integer tableColumnValue = (Integer) jComboBoxColumns.getSelectedItem();
tableModel.setColumnCount(tableColumnValue.intValue());
tableModel.fireTableDataChanged();
}
});
This is VERY generic. Basically you use a 'DefaultTableModel' and change the model using a 'set' or 'add' or 'remove' for columns and rows. Then you MUST FIRE an event so the UI will refresh based on model changes. The two listeners are naive but it puts you on the correct path. Sorry I couldn't give a better example. Running out of time... :-)
Good luck!

I added screenshot of Windows Forms example. User enters some numbers in the cells, then programm do some stuff with that. TableView confuses me because I can't control number of visible rows, so the only way I see to show user where he should print numbers is to set Promt text "enter numbers here" and make other rows uneditable. That will look pretty goofy for me, am I missing something that can make it look prerry?

even if Swing would be the theme - your answer is plain wrong: you never-ever need to call any of the tableModel.fireXX methods in application code if everything is wired correctly ...
