collections.Sequence

[Appletrain]

Using a copy of dialogs, get the following error: “collections has no attribute Sequence” and “collections.abc has no attribute Sequence”.

Any help?

@Appletrain This may help.

# Python 3.10 has put Sequence in collections.abc instead of collections
import collections
collections.Sequence = collections.abc.Sequence

Thank you, that fixed it.

Also, datepicker is fubar.

datepicker is fubar.

If you mean that ui.DatePicker does no more show a wheel, you could try this

import ui
from  objc_util import ObjCInstance

v = ui.View()
v.background_color = 'white'
dp = ui.DatePicker()

objc = ObjCInstance(dp)

@on_main_thread
def setWheel():
	objc.setPreferredDatePickerStyle_(1)
setWheel()

v.add_subview(dp)
v.present()

Thank you. Now I think I understand it. How do I get the result? I assume I have to call action somehow.

[cvp]

@Appletrain yes, action is called each time you change the date

import ui
from  objc_util import ObjCInstance

v = ui.View()
v.background_color = 'white'
dp = ui.DatePicker()

def dp_action(sender):
	print(sender.date)
dp.action = dp_action

objc = ObjCInstance(dp)

@on_main_thread
def setWheel():
	objc.setPreferredDatePickerStyle_(1)
setWheel()

v.add_subview(dp)
v.present()

Thus, you need also to close the datepicker to get the final selected date

@cvp

Great, thank you. I guess I should get familiar with objc.

[cvp]

@Appletrain If you prefer to use dialogs.date_dialog you can also monkey patch it with this code

import dialogs
from  objc_util import ObjCInstance
import ui

# to change an attribute of the dialog ui.DatePicker, we need
# to do it before it is presented
# the next mehod is called internally in _DateDialogController
# monkey patching of __init__ method, see dialogs.py

original_init = dialogs._DateDialogController.__init__

def new_init(self, mode=ui.DATE_PICKER_MODE_DATE, title='', done_button_title='Done'):
	original_init(self, mode, title, done_button_title)
	ObjCInstance(self.view).setPreferredDatePickerStyle_(1)

dialogs._DateDialogController.__init__ = new_init

dt = dialogs.date_dialog()
dialogs._DateDialogController.__init__ = original_init # to avoid recursion error

print(dt)

@random_soul you could be also interested by previous post.

@cvp

Thank you. That gives me another piece to the script I’m working on. I
never thought of “monkey patching” as I don’t use it much.
