  if you are asking for help, a gist or code is helpful. otherwise i can only guess.
  If you are experiencing crashing, you should install dgelessus's fault handler to log the exact cause for the crash (the latest beta does this automatically)

  @abcabc Tank you very much for your tip. It was very informative. The panel view reveals itself to be useful to host "editmenu"' s routine. I moved to python about a year ago from C++ and delphi. I was looking for a language that could easily be ported in source code to all five major platforms (MS Windows, OSX, iOS, Android, Linux). I developed the C.O.D.E. (Code Once Deploy Everywhere) concept. Using Pythonista on IOS and Kivy on the other platforms I finally developed an adaptable structure that could be used in all these platforms without modifying the Python scripts, not even the ui scripts. However, I do not go into learning the details for the ui in each environment since they can be changed by the dev at anytime. This is why your reply was so valuable.

  [Lab] Function to easily create a vertical view of views

  A small breakthrough in thinking. I created a split view horizontal function below. I have it working, but need to quite a bit more to clean it up and follow same API as the vertical. But almost 1am here now, time to go home eat some food and watch some series until,I pass out 😱💅🏽
  Will,finish this tomorrow, well actually it tomorrow already

  def split_view_hor(parent, v): v.width = v.width / 2 r = ui.Rect(*v.frame) r.x = r.max_x nv = ui.View(frame = r ) nv.flex = v.flex nv.bg_color = 'yellow' v.superview.add_subview(nv)

  @ccc , yes I get you about a 3 line function, but to change the colors was just to show something happened. Was not the practical use in this case. The idea each button would be performing a totally different function.
  But look it does not really matter. I get you. You are a disciplined programmer. You cant easily turn that on and off; you see it one way, the right way as you perceive it. I was the same way when coding was my profession. It also served me well. You have to be like that or at least you should be in my view. But I am back to amateur status with not much chance of getting beyond that unless I give up the BL 😬

  How to Connect Table View Methods to UI Builder (Storyboard)

  @GroundhogDayLoop, using the ui.View you assign to your .pyui file you can access the ui.Table by the name you give it in the builder.
  Eg

  v = ui.load_view('my_view.pyui') tbl = v['tbl_name'] # can access any of the elements this way

  By default tbl load from a pyui file has a ListDataSource already attached correctly as the data_source. Of course you can change it. But it's work having a good look at the ui.ListDataSource before doing so as it's quite powerful and can save you some work as well you can extend it if you need to.

  One thing to keep in mind. The code above works if your table is on the root/parent view in the builder. If you for example placed a CustomView then added the TableView to the CustomClass (so TableView is now a Subview of the CustomView) so then you would refer to your TableView like -

  tbl = v['custom_class_name']['tbl_name']

  I hope that last part is clear

  Aha - you're right! I moved my code line (the send_to_back) into after the subviews are created rather than when all the attributes of the element are setup and it works wonderfully. Thanks!

  if you are able to install your own wireless bridge in your classroom (not sure if all routers let you do this, certainly ones supported by dd-wrt can), then you could log them into the router, then lock them into pythonista. on the router, you would set the firewall to only allow sites on a whitelist.

  Another option may be a custom ui module, which you place in site-packages, and which stubs out ui.WebView, or maybe even implements a white list. You could show a "siteminder" page for sites not on the whitelist, so they think it is a router limitation and don't keep digging. Maybe log such attempts, so you can figure out who the aspiring hackers in your class are.

  ok, another option... you could install into site-packages a pythonista_startup, which uses objc to swizzle the underlying UIWebView class to be nonfunctional. Then use the chmod trick above to prevent casual editing of that file.

  For packages hosted on pypy, you can install stash, then use the pip command

  pip install pydicom

  for pure python packages (which do not have C dependencies), this works maybe 75% of the time. in some cases, you may need to use pip download, then manually un tar or unzip the file, and copy the main package folder into site-packages.

  For things on github, you can use git clone, from within stash. Or you can use wget with the github archive url, then un tar or unzip again with stash.

  For individual files, I recommend
  https://gist.github.com/jsbain/fcb3f42932dde9b0ff6c122893d1b230
  which you set as an application extension script, so you would navigate to the file in safari, then use the share menu to run the savefile script, which will place the file in your Documents folder.

  Unfortunately, this type of thing is usually prett opaque in dulwich, since the server closes the connection, and dulwich does not know why.

  are you able to clone github repo's?

  You could try installing the latest dulwich, then use dulwich.porcelain, (not with stash) along with pdb to try to trace through what is happening, but if you search for the specific error in dulwich.client, I think you will find there is nothing that dulwich knows about.

  Pythonista 2.1 problem

  "A few other things changed in 1.5 to 2.x but mostly old scripts can be fixed in a few lines..."
  It probably is that easy for you. Therefore, I have a simple request. Please update "editmenu" to work properly with Pythonista 2.1. Maybe You could use your excellent "uicomponents" to do so. By the way, a few of those ui routines do not work either in version 2.1. I also downloaded "objc_hacks" and it shows wonderful possibilities in version 2.1. Inserting ui elements in the interface is a fantastic feat. You could do marvels with the "find and replace" module in "editmenu" by using it. I do not think that "find and replace" in the new Pythonista editor is better than yours. Visually and functionally "editmenu"'s "find and replace" is way more appealing and functional than Pythonista's. Thank you very much for your insightful reply and your outstanding published work. Hoping that you will take my request into consideration, I salute you.

  I do a lot of discrete signal processing and neural networks and would LOVE scipy. I would also LOVE support for pcapy, dpkt, and Scapy although I suspect that they wont work because they require root permissions.

  @dgelessus, ok. But my point was if you use an external keyboard, then the dynamics change. You will feel you can type fast enough on the external keyboard that snippets will not feel,as important to you as if we're using the on screen keyboard. Even though they as just as relevant.
  But I am not complaining, you put out some great code. That matters more than how you got there

  Don't think toooo hard before you post to the forum... we love to see your crazy ideas in their raw form. But do consider running Check Style and Analyze (PyFlakes) as they find simple issues (like your unused variable) and push you to make your code more readable. I have become big fan of autopep8 on my Mac. It would be cool to see that level of automatic reformatting as an option in Pythonista.

  Perhaps you want to be presenting a modal view, not a modal scene?
  For instance, present your login view as a popover or sheet, then wait_modal on the view to wait until it is closed.
