[ANN] Kivy 1.9 released

[qua-non]

Hi everyone,

We are pleased to announce Kivy 1.9.0

Kivy is a full featured framework for creating novel and performant

user interfaces, such as multitouch applications, released under the

MIT license. The framework works on Windows, OS X, Linux, Android, iOS 

and Raspberry Pi.

All downloads are available on the website:

    http://kivy.org/#download

If you appreciate our project and would like to support us financially, we now

have a donate section set up along with an organization to manage the funds.

Head over to http://kivy.org/#organization

Main features of this release we want to highlight:

    

- New SDL2 provider (Window, Image, Text, Audio, Clipboard) on desktop and iOS.

  This feature is available by default.  Pygame backends are now deprecated on

  platforms where SDL2 is available.

  SDL2 provides us a better Window support, no loss of OpenGL context when

  resizing, Retina screen support, less crashes :)

- New ffplayer provider (Video, Image) on desktop and iOS.

  See http://matham.github.io/ffpyplayer/installation.html for more details.

  This provider is now the default Video provider on iOS.

- EffectWidget: Allows for easy manipulation of  the child widgets using preset 

effects (shaders) or to write your own. This is essentially the easiest way to

get shader effects onto your widget.

- FocusBehavior: FocusBehavior generalizes the focusing behavior displayed by

TextInput that allows a widget to react to receiving user input from a keyboard.

For more details see: https://github.com/kivy/kivy/pull/1909

- Rebind Support: Add rebind option to Property to allow dynamic rebinding of

properties in kv. When set to True for that property, kv rules using this object

as  an intermediate attribute in a kv rule, will update the bound property  when

this object changes. For more details see: https://github.com/kivy/kivy/pull/2100

- SVG Support Preview (Python 2.7 Only): Initial support for rendering of SVG.

Known Bugs

==========

 - Svg broken in 3.3, it can be announced for 2.7, not 3.3 yet

Migration

=========

There are no fundamental changes to the way things work.

However we did move away from using Pygame backends to using

SDL2. 

If you are using Pygame functions /APIs directly

be forwarned that you will need to handle things yourself.

On behalf of Autosport Labs we are delighted to hear this news! We make race car telemetry hardware and software and Kivy is central to our effort. http://autosportlabs.net/RaceCapture_App_User%27s_Guide

Good move on the donation page as well, we were just going to ask about this!

[python...@gmail.com]

Looks like a very significant update.

I own Pythoncoding com web site which I have starting putting content up and I have decided to have a new area called Phones and Tablets and I am thinking to feature kivi on it.

Should anyone like to help me with that then please email Ja...@Pythoncoding.com or Python...@gmail.com
If not I will figure it out and create my own content and tutorial for kivi.
Kivi looks cool and nice to get Python apps for phones and tablets. That is important.

[Charles Granet]

Bravo and thank you so much!

...

[ZenCODE]

Great job, thanks all! Especially the Android audio - fixes the position and volume issues I was having. And nice to have basic SVG support arriving. Yay! ;-)

[JetK]

Thanks for fixing the text input issue where the last letter was stretching if it had reached the end of the box!

But how do we correct the libpng warning: iCCP: known incorrect sRGB profile which was introduced in 1.9.0?

[qua non]

@JetK  could you open a issue for this? Does it lead to a issue opening some png or is it just a warning?

I'll try to (never done it before) open an issue for it.

It's really just a warning message for some of the .pngs in the console. They appear at the start, but loads them fine.

[JetK]

Hmm, it happens even with regular example files, which don't even use pngs (unless it means the button atlas?), like app_with_kv.py.

Also I've noticed you can't hide the cursor anymore like you could in older version with show_cursor: int, one of 0 or 1

[qua non]

Show curse thing seems like a bug. The libpng error is cause they choose to show errors on pngs of certain types in the new version that they didn't before. It's essentially a harmless message telling you that your pngs are probably broken in some small respect.

The cursor and animation issues should be opened up on github.

[Malik Brahimi]

Please help me with my problem here. I've been waiting for answers for quite some time, and I have yet to hear from anyone.

[Steve B]

Sounds Nice, I hate to offend any ones good work but the latest github offerings are so broken I really don't know were to start. I'm left frantically trying to find old 1.8 backups so I can building apps again. I hope it gets fixed soon. And yes I have given up cuz no one replies :( 

...

[Alexander Taylor]

They're so broken that they work fine for most people.

Where did you report your problem?

Hi, i'm new in kivy but i'm fascinated with it. i must apologize for my English and for any inconvenient if a jump any protocol about how all this work, but i'm new in everything really.

I have been studying python for a while and just for a days kivy and most of the info online is for the previews versions. now i don't seem to be able of handle well the size, size_hint, pos and pos_hint in the .kv file. don't know if it is an specific issue or i'm doing something wrong. Would thank any help.

thank for all and the amazing work.
