Problems with ios15

JonB

I wonder if this is a navigation view problem. Try presenting view without creating a nav view.

@JonB Presenting the view directly without the nav view has the same issue on my iPhone 12. The first line in the console is after wait: None

A workaround might be to use a Lock.

def show_list_dialog(items=None, *args, **kwargs):
    items = items or []
    tbl = ui.TableView(**kwargs)
    tbl.data_source = ui.ListDataSource(items)
    my_sel = {'value': None}
    import threading
    lock=threading.Lock()
    class MyTableViewDelegate (object):
        def tableview_did_select(self, tableview, section, row):
            print('items:', tableview.data_source.items)
            print('section, row:', section, row)
            my_sel['value'] = tableview.data_source.items[row]
            tableview.close()
            lock.release()
            print('in delegate: my_sel',my_sel['value'])
    tbl.delegate = MyTableViewDelegate()
    tbl.present(style='sheet')
    lock.acquire()
    #tbl.wait_modal()
    print('after wait: ', my_sel['value'])
    return my_sel['value']

See if that solves it

This code works on my iPhone 12.

I added @ui.in_background to def select_author(sender)

I will also test the Lock code.

import ui
#
def show_list_dialog(items=None, *args, **kwargs):
    items = items or []
    tbl = ui.TableView(**kwargs)
    tbl.data_source = ui.ListDataSource(items)
    my_sel = {'value': None}
    class MyTableViewDelegate (object):
        def tableview_did_select(self, tableview, section, row):
            print('items:', tableview.data_source.items)
            print('section, row:', section, row)
            my_sel['value'] = tableview.data_source.items[row]
            tableview.close()
            print('in delegate: my_sel',my_sel['value'])
    tbl.delegate = MyTableViewDelegate()
    tbl.present(style='sheet')
    tbl.wait_modal()
    print('after wait: ', my_sel['value'])
    return my_sel['value']
#
w, h = ui.get_screen_size()
view = ui.View(name="Frank's Library", bg_color='lightblue', frame=(0, 0, w, h))
 
@ui.in_background 
def select_author(sender):
    author_unique = ['Baldacci,David', 'Barr,Nevada', 'Bartol,Amy', 'Bernt,Eric', 'Brandt,Kylie', 'Bruni,Riccardo', 'Bryndza,Robert', 'Burke,James Lee', 'Burton,Mary', 'Butcher,Jim', 'Carlson,Tucker', 'Carrol,Sean', 'Case,Andrew', 'Chernov,Ron', 'Clayton,MegWaite', 'Coben,Harlan', 'Cole,Bobby', 'Connelly,Michael', 'Cornwell,Bernard', 'Cornwell,Patricia', 'Cowie,Amber', 'Crombie,Deborah', 'Crosby,Ellen', 'Cross,Katie', 'Cussler,Clive', 'Delaney,Matthew B.J.', 'Dilts,Tyler', 'Dorsey,Tim']
    f = (0, 0, 400, 300)
    selected_author = show_list_dialog(author_unique, frame=f, name='Select an Author')
    print('list dialog returned:', selected_author)
    global author_result
    author_result.text = str(selected_author)
    return
 
author_button = ui.Button(title='Author', frame=(10,5,350,100), border_color='black', border_width=2, background_color='#EAECEE', action=select_author, font=('Arial Rounded MT Bold',18))
author_button.width=70
author_button.height=40
view.add_subview(author_button)
#
global author_result
author_entry=''
author_result = ui.TextView(name='author',frame=(100,5,250,40), border_color='black', border_width=3, text=author_entry, font=('Arial Rounded MT Bold',16))
view.add_subview(author_result)
 
view.present('sheet')
#nav_view = ui.NavigationView(view)
#nav_view.present('sheet')

Ok, that makes sense. You can't have a wait_modal on the main thread, since you wouldn't be able to interact with the gui.

Thank you bosco. That fix works for me on iPhone12.
