B4J Library jTableViewExtended

This library extends TableView and provides more control on the columns, rows and cells.

What you get with TableView:

What you can get with TableViewExtended (with the same data):

You can easily enhance an existing TableView by initializing your TableViewExtended with InitializeByExtending(MyExistingTableView).

Changelog:
v1.0:
- I added the TableRow class;
- I added ClearSelection, DisableReorderingColumns, FixedCellHeight, MultipleSelection, Placeholder, SelectedCells, SelectedRows, SetRowEventsListener, Sort and SortOrder to TableViewExtended;
- I replaced RowIndex and RowStyle by Row in TableCell;
- I modified the example to open a message box on double-click on a row.

v1.1:
- I added the Column property to the TableCell class.

v1.11:
- I fixed an issue with OpenJDK 11 in the DisableReorderingColumns function.

Thanks @Informatix for the extended TableView code with extra features.... It is really nice.

Is it possible to show tableview with expandable records, I mean showing child records under parent records with parent record can be expanded or collapsed?

No. It's not a feature of the JavaFX TableView and I don't plan to add it. You have to use the TreeView class.

Ok.. thank you for your reply.

While searching further on this topic, I found following youtube video which demonstrates Expandable Tableview capability, this really looks nice and will be very helpful in most of the projects. I believe it is written in Java and being non-java guy, I am not sure how to port it in B4J. If @Erel or anyone could help over here to build a library.

Thanks in advance.

The code that you see in the video is not in Java. Anyway, doing the same thing requires to wrap the ControlsFX.TableRowExpanderColumn class first. So, unless someone has some time to wrap and share it, there's no easy solution for now.

I tried your example and now i have two questions: whats the standard way for static formating of columnheader? Are css styles the only way?
Is your Expandable Tableview also useable for customized row formating and if yes, can you make some hints?

Thanks in advance.

You have to use a CSS file or the Style property for the column headers (note that the Style property value is applied to all cells of the column).

Is your Expandable Tableview also useable for customized row formating and if yes, can you make some hints?

Look at the demo. It shows how to format cells (CellFactory) and rows (Cell.Row.Style=...).

Sure, I understand.. I will wait till then .. Thanks..

Hi,

I would like to use this tveCities.SelectedCells(). But I don't know how ? I need to use it to retrieve the cell data.
Thanks

From the documentation:
"Returns a two-dimensional array containing the position (row, column) of selected cells."

It's an array inside an array. It's not obvious indeed:

Dim C(,) As Int = tveCities.SelectedCells
For i = 0 To C.Length - 1
       Log("Row = " & C(i, 0) & " / Col = " & C(i, 1))
Next

Thanks for help

Thank you for this class @Informatix !

Anyway, doing the same thing requires to wrap the ControlsFX.TableRowExpanderColumn class first

or is it the TreeTableView class that should be wrapped?

No, it's a TableView. The code proves it.

How to trigger the edit function without double clicking the cell (tablecell = sender).

I'am trying to make it using keypress of enter or F2.

I'am now successfully getting the keypress event of tableview and my problem is how to trigger the edit event.

Just like this

    Dim C(,) As Int = tveCities.SelectedCells
    If C.Length >= 1 Then
        Log("row: " & C(0,0))
        Log("col: " & C(0,1))

        Dim tablecell As TableCell = c
        'proceed to edit cell
    End

        Dim tablecell As TableCell = c
        'proceed to edit cell
    End

In the demo, you should copy the code from MousePressed:

'Marks the cell and raises a CellFactory event to replace the text of the city name by a TextField
EditedCell = Cell
EditedCell.Tag = Cell.Row.Index
Cell.Update

'Sets the focus on the editor (requires to consume the event first)
EventData.Consume
tfEditor.RequestFocus

How to set value for cell?

EditedCell = Cell -> where this value came from without clicking.

EditedCell = Cell -> where this value came from without clicking.

According to the snippet of code you posted, this should be "EditedCell = c".

Sorry but i think you dont understand what i am asking.

ok let me breakdown it.

to edit a cell you need to double click it and convert the cell to a textfield.

what do i want is to make it editable without double clicking it.

tnx
