Pythonista View Sidebar

mikael

@DavinE, the error comes from anchors, and I have seen similar when a view does not have a superview.

In this case the problem is likely with how you ”throw away” the sidebar when you recreate it.

This tells me I should add a convenience method that you can call to remove all anchors for a view and its subviews.

But in any case, I would suggest having two different sidebars, one for customers and one for orders, not throwing them away but hiding them, and using a ui.TableView for their contents, as you would then get scrolling and editing options for free.

okay i tried it with an ui.TableView

That would be nice and i think a bit easier

Thanks :D

@mikael EDIT:
Is it possible That you can show me an example?
I dont get it... its always the same error or it pops both views up :(

But how it works when i make more pages like..

Startpage
Add User
etc....

how can i close here my pages or is it then same like this:

self.root.remove_subview(view) ?

or is it here special

mikael

@DavinE, you can have two sidebars, and move the one you do not need outside the screen, or both when you want to show the main content only.

If you have several pages, you can also consider ui.NavigationView for paging.

@mikael i found an working solution for me ;) ^^

i have an other Question... about Labels

when i use the label like:

size_to_fit(ui.Label(name='welcomeLabel', text='a very long text.........'))
size_to_fit(ui.Label(name='welcomeLabel', text='a very long **\n** text.........'))

on small Devices my text is cutted on both examples....
do you have an solution for me :D ^^

thanks and regards

It seems to me that your options are to either change the font smaller, or text wrap it so it takes up more lines, fewer columns. The textwrap module has a wrap function that is good for limiting text to some number of columns. I'm sure there is probably a iOS objc way to do the same, within the text view inside the button...

Buttons with really long text are not really the way iOS designs are supposed to be made... Usually there is a better way.

mikael

@DavinE, ui.Label has a standard feature where you set number_of_lines to 0, and it will wrap to as many lines as are needed.

It is often convenient to set the width to something suitable, then call size_to_fit to make the height fit the amount of text you have.

Many different font sizes on one UI can be ugly, but if that is not a concern, you can also have a loop where you use ui.measure_string to check if the text fits, and make the font size smaller if not.

@JonB Thanks for your Reply but @mikael have the solution....

i tried so many things but to call Size_to_fit after that...
crap---

thanks @mikael !!

@mikael
Did you do that for anchors ?

mikael

@DavinE, do you mean an anchor removal method? I think I did not. Do you need it?

DavinE

@mikael maybe it's a better way to remove Sidebars ?
In my case i get often errors when i Rotate my iPhone (this is solved with your code in my other Post) or iPad
or an other example when i close the Sidebar and reopen it i'll get en error too..
so at the moment i don't close the View i put it away form the main view

only when it's not a lot of Work for you ;)

i Hope you understand what i want ^^
or need i do an Example ? (when i can reproduce it)
