Thank you again for saving my project (and sanity)
I had read that thread before, but didn’t make the connection.
Here’s what worked for me:
I ended up using
vi = ObjCInstance(b)
Since my object ‘b’ is ui.Button
Also, the popover location was off by the title bar height. Used GetTitleBarHeight() from here. Adjusted popover padding with help from here.
I appreciate how helpful this community is. I’m learning a lot.
Hi all-
I’m trying to present a popover triggered by a button in a TableViewCell.
My underlying table is a TreeNode (from File Picker) and so I can’t use row_height * row index calculation.
Converting button.center to screen_coordinates is where I’m getting stuck (I think this is how to accomplish the task)
Any thoughts?
@JonB thanks for the suggestions.
Hi all,
I have multiple tableviews presented in navigationview. There is a textview in the root view. I want to collect all user selections (from all nav views) and display in textview.
I'm getting stuck on how to update the textview when a selection is made in deeper sub-levels.
What if the individual tables are generated from separate classes?
Can you point me towards a strategy to accomplish this task?
thanks

@cvp. Helpful! Thank you.
@cvp Thank you for taking the time.
I think I was making it harder than it should be.
@crazyfox first, replace load_str by load_view_str 😀
...I see it now. Editing/posting error trying include pyui string.
@crazyfox sincerely, I don't understand your
cell = ui.TableViewCell() cell = MyDropDown(tableview, section, row, frame=(100,0,200,100), items=itemslist).as_cell()
...This evolved out of series of TypeErrors and issues with arguments I could not fix elegantly.
Much more to learn. Thanks again for your help.
Until next mental block.
-KP
Thanks @cvp
This is what I’ve cobbled together (with inspiration from @cvp and @jonb.
Very crude.
I’m an absolute beginner, so any feedback is appreciated.
Thanks, KP

Hi all,
Any ideas on recreating the UI seen in Apple Mail rules (attached) or similar(smart mailboxes, etc)? i.e. Expandable table with multiple dropdowns in each row.
I am populating tableviewcell_for_row with custom UIView class and other standard elements. The layout has been difficult to define and dropdown selections are restricted to row height. I think I can make it work but is not pretty.
Is there a more elegant way to approach this?
KP
I’m having the same issue.
iPad Pro 13.3 cannot see snippets button.
Disappointing as this was a big selling point for me.
Am I missing a setting somewhere?
@BGKirkham
Thank you. Sorry didn’t mean to hijack your thread.
@cvp
It works. Thanks again for pointing me in the right direction.
@cvp Thanks.
I will go through your code - just starting with Python.
Would I need to put this code in a class in order to call it multiple times -multiple drop downs on ui sheet (and passing different parameters)?
