Hi all,

When trying to use a dialogs.list_dialog from within an Ui.view I got no result back from dialog. Is this a bug or do I misunderstood something?

Apparently UI and dialogs don't mix:

• If the @ui.in_background line is commented out then action() only runs once you have closed view.
• If the @ui.in_background line is not commented out then dialogs.list_dialog() always returns None.

import dialogs, ui

@ui.in_background  # try it with this line commented out and with this line not commented out.
def action(sender):
    print('action() starts')
    #sender.superview.hidden = True
    #sender.superview.sent_to_back()
    print(dialogs.list_dialog(sender.title, sender.title))
    #sender.superview.hidden = False
    print('action() ends')

view = ui.View()
button = ui.Button(title='Show List')
button.action = action
view.add_subview(button)
view.present()
button.center = view.center
# view.wait_modal()  # FIX: commented out as suggested by @omz below.

If you remove the view.wait_modal() line, it should work.

That works!

Ok, got it. I forgot the @ui.in_background

Now it works

When using the dialogs module, is the size of the text_dialogs box fixed or can it be made a specified size?

It uses a fixed size, but you could define your own text_dialog function like this:

import dialogs
import ui

def custom_text_dialog(size=(500, 500), title='', text='', font=('<system>', 16), autocorrection=None, autocapitalization=ui.AUTOCAPITALIZE_SENTENCES, spellchecking=None, done_button_title='Done'):
    c = dialogs._TextDialogController(title=title, text=text, font=font, autocorrection=autocorrection, autocapitalization=autocapitalization, spellchecking=spellchecking, done_button_title=done_button_title)
    c.view.bounds = (0, 0, size[0], size[1])
    c.view.present('sheet')
    c.view.begin_editing()
    c.view.wait_modal()
    return c.text

print 'Result:', custom_text_dialog(size=(300, 400))

(this is basically just a variation of the actual text_dialog source code)
