Table widget?

[zw g]

Hi guys,

Is there any table related widgets in Kivy framework?

I want to write an audio player. I need a table or something like that to display playlist.

Any suggestion?

Thanks in advance.

Something like BoxLayout or GridLayout?

No, it's more like a excel sheet widget with rows & colomns & headers elements.
Which is suitable for all kinds of information for a song, suck as: Title, Album, Artist, Duration, Genre....

I know a bit skills of PyQt4.  (Compare to Kivy, it's more matured, but without support for iOS & Android.)
In PyQt4 there are two widgets:
1) QTableWidget

2) QTableView
http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/html/qtableview.html

You can see some screenshots in the above links.

Ok, no, we don't have things of that kind, you can emulate that with a
GridLayout with buttons in the first row (to sort the subsequent rows
based on current column) and labels (or buttons if you want to start an
action on click on them) for the next rows, and put the whole thing in
a ScrollView if you want the scroll thing, it shouldn't be very hard to
do, create an update() callback that can sort your data based on the
index of your row and fill the the table with the good elements, kivy
widgets are lower level than Qt ones, but they are flexible enought
it's not too much work to do that.

If you do the TableWidget generic enough, it could be a welcome
addition to kivy widgets :)

If you have troubles doing it, we'll try to help :)

It's good to know these.
Thank you very much.

Been researching about this and found this message, and was able to emulate all of that except for one thing. I can't change the scrollbar to the traditional one. Was able to make it visible thanks to other information here, but its not clickable. Meaning I can't control the scroll using the bar.

Any ideas how to do this? My vague idea is to check on_press_down if it is within the area of the scrollbar and write code to scroll it down. But maybe there is another way?

[Gabriel Pettier]

I think that's the idea. I would check for position in on_touch_down,
grab the touch to get updates (on_touch_move), and in on_touch_move,
would check for touch.dsy (vertical difference between last event,
relative to widget size[1]), and scroll accordingly. Don't forget to
ungrab the touch in on_touch_up.

Good luck.

I've been working on something like that, reuse the code for your needs if you want to.

Here:

https://github.com/pedrodgcouto/kivy.data_grid

I'm still developing it, but i will make it more usable, in fact, i've already got a version, but it needs some adjustments yet, in the meanwhile, take a look at it.

Best regards,

Pedro Couto

Thank you all!

Will try to create the functions for the scrollbar.

And thank you for the code! That helps a lot

hi,

How can i loop thru gridlayout for reading values for insert to database

[Federico Curzel]

Check also out my project : https://github.com/Cuuuurzel/kivy-pro-grid
I was able to also run it smoothly on mobile.
You can customize column sizes and colors.

Hi Federico,

Wile running demo i got following error

   File "C:\Users\softx2\Desktop\kivy-pro-grid-master\progrid\progrid.py", line

381, in _gen_header

     text = u' '+text if first_col else text

 TypeError: Can't convert 'bytes' object to str implicitly

Old topic, but I have to ask... are there no plans on developing something similar to PyQt's QTableWidget?

This is actually one thing holding me off attempting to port my PyQt/PySide application to Kivy as I am using QTableWidgets extensively.

Think of a table widget as an Excel/Google Sheets document. There are rows and columns making up the table of cells. Then you can set this table to e.g. hide the colum header or row header, you can choose whether a selection selects the whole row, whether the cells can be edited etc... any way, very useful.

What are the current workarounds?

Regards,

Fredrik

Any update? I still stuck on pyqt because of tablewidget :/

[Johnny T]

That is some very useful information. But what can I do if I want my first row to be visible all the time? (a.k.a. not scroll with the rest of the rows)

[Will Tejeda]

I’d guess that you’d have two layouts inside the grid layout 

GridLayout:

    

    Grid Layout:

        Button:

        Button:

        Button:

        Button:

    Scrollview: 

        Gridview:

            Playlist items
