I have an idea rattling in my brain and one of the big pieces of it is about UI.
With UI in Pythonista, is it possible to have a secondary presentation shown on an external display (projector, TV) via Lightning to HDMI/VGA adapter?
So one potential application would be having a grid of slides on your iPad UI with a projector only showing the currently selected slide.
This is a possible thing in iOS. I have some apps that have a "presentation mode." (Keynote for example does this (by default?) when connected to an external display).
Anyway- wondering if it's possible! Thanks!

Okay- thanks for your input. I really was wondering if it's possible- of course getting there is always the interesting part.
For now I'll put this on the shelf. I don't have the beta and I'm really just a beginner at Python - trying to add in objective C makes things sound very complicated.
Perhaps someday I'll try at this one! I have a lot of use for something like that- (a lot of presentations)!

I also would like to know how to do this. After entering text into a text field, pressing "done" or "enter" ...how to hide the keyboard?

I'm just fiddling with something....would appreciate some input.
If I have some HTML code with CSS and put it into ui.webview.load_html() it seems it cannot handle all CSS parameters.
I don't know the scope of CSS that it can handle, but I found that table properties don't seem to work.Simple Example to use as html to pass to load_html():
<html><style>table {border-width:1px}</style><table><tr><td>This table should have a border</td></tr></table></html>
It won't have a border. At least from what I've tried!
However, the below method will provide a border, however this is poor way to go about things in html:
<html><table border = 1><tr><td>This table should have a border</td></tr></table></html>
Is there something I should do to get that working....?
Also note: ui.Webview itself handles CSS properly if I load an actual webpage (load_url).

You're right about all of those things.
CSS can be used in three ways - externally linked, internal <head><style>...</style>, and in the tag <table style="...">
For what I'm doing right now- the internal style sheet is sufficient and arguably easier(?). I'm scraping some html and then showing it in webview.
Could do re.sub but I'm just adding a bunch of stringy html code and that's easy enough! -

sorry- it seems I can't delete this.... I answered my own question:
(hrm...seems I need to read up on my css!){border: 1px solid black;}

First off, hi! I'm pretty new to Python- having a lot of fun figuring things out. I check this forum often so thank you all for your help.
Here's my question:
Has anyone successfully installed and been able to use the regex module? USE is the key word...!
I was able to do the different steps: download from PyPi...unpack...move
I actually had to install it on my PC using In order to get a file that is generated from the setup.Anyway after all that, lots of errors. Mainly import errors.
It seems as though some modules don't play nicely in pythonista.I wanted to get this working because I'm trying to work with Japanese characters and the re module apparently doesn't cut it (which is true- I got some wacky matches using findall)
So- any success? If so, what did you do?

Okay it seems to work now after using unicode().
Basically I was doing a (?<=)[dog]+(?=) search on a list of words- but with Japanese characters and different lookahead/behind. The aim is to find words that use those characters.
Without making Unicode strings I got (false positive?) results like this: 中=丸. Very weird! The list I have has 140,000+ entries so there were a lot of false matches.
Thanks again for your help!

Okay thanks...great responses!
I didn't know that regex also had C code! :)
Some of those things I knew about Unicode in Python, some I didn't. I'll try later and see what happens!
