[KivyCalendar] Calendar & DatePicker widgets

[Oleg Kozlov]

Hello.

I work under small project on Kivy. App users need to be able to select date (day.month.year like 06.03.2015) from user-friendly widgets like DatePickerCtrl and CalendarCtrl from wxPython.
I designed two new Kivy widgets for my goals: CalendarWidget (like CalendarCtrl from wxPython) and DatePicker (like DateOickerCtrl from wxPython) and placed them to external python-module named KivyCalendar.

May be that will be useful for someone else.

Source code available on bitbucket.org (mit license).
Module can be installed via pypi
pip install KivyCalendar

Use as any other kivy widget (just import module first)

from kivy.app import App
from KivyCalendar import CalendarWidget

class MyApp(App):
   
    def build(self):
        return CalendarWidget()

MyApp().run()

from kivy.app import App
from KivyCalendar import DatePicker

class MyApp(App):
   
    def build(self):
        return DatePicker()

MyApp().run()

Tested only with Python 2.7.9 and Kivy 1.8.0 on Mageia 4 i586 (GNU/Linux, 32-bit).

CalendarWidget use translated with system locale (lang) days abbreviations. My system locale is ru_RU.UTF-8 and I don't tested with other langs.

[xxblx@localhost ~]$ echo $LANG
ru_RU.UTF-8

If you found a bug, module segfaults with your lang or here some other issues, feel free to contact with me.
Also if it prefer for you can use bug-tracker.

Feedbacks are welcome.
Thanks.

Hi,

We tend to ask user avoiding naming their project KivyXXX, to prevent confusion. (As lot of users think because it's named kivy, it's our responbility to maintain it, or we did it.)

The Garden has been created specifically for that, and we're working on a beautiful widget listing on the website based on the current garden list. Check all the current widget available: https://github.com/kivy-garden/

Garden is managed and for the community, and we provide a tool to manage the dependencies in your app and system as well.

More informations at: http://kivy-garden.github.io/

About your widget... it's beautiful! Bravo :)

Nice!

 Sorry about module name. How it better to do now rename module or left as is (module already uploaded to pypi)?

[Oleg Kozlov]

Update to 0.1.1 uploaded to pypi.
Fixed: added error processing - if impossible to use system language for days abbrs and months names translation will be used english abbrs & names.

Hi guys.

This is probably a total noob question... but I can't figure it out how to use this widget.

Here is an example of my code:

from kivy.app import App from kivy.uix.boxlayout import BoxLayout from kivy.uix.textinput import TextInput from kivy.uix.popup import Popup from KivyCalendar import CalendarWidget from KivyCalendar import DatePicker

class SetIndex(BoxLayout):
def setDate(self, *args):

popup = Popup(title='Insert Old Date', content=CalendarWidget(), size_hint=(.9, .5)).open()

class MainApp(App):

def bulid(self):

return SetIndex()

if __name__ == '__main__':

    MainApp().run()

and the .kv file:

BoxLayout:
    orientation: "vertical"

  size_hint: 1, .4

   

  TextInput:

      id: old_date

      hint_text: "Old Date"

      on_focus: root.setDate()

Any hint on how to make this work?

Thank you!

[Oleg Kozlov]

Hello.

First of all, look at MainApp methods. You wrote "bulid", fix to "build" :)


What probably you trying to do?

If you want just to open CalendarWidget at app start. That easier to return directly calendar widget.

from kivy.app import App
from KivyCalendar import CalendarWidget

class MyApp(App):
   
    def build(self):
        return CalendarWidget()

MyApp().run()

Fix for yours code look like

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput
from kivy.uix.popup import Popup
from KivyCalendar import CalendarWidget
from KivyCalendar import DatePicker

class SetIndex(BoxLayout):
   

    def __init__(self):
        super(SetIndex, self).__init__()
       
        self.init_ui()
       
    def init_ui(self):   
       
        self.cal = CalendarWidget(as_popup=True)
        self.popup = Popup(title='Insert Old Date', content=self.cal,
                           size_hint=(.9, .5))
        self.popup.open()

class MainApp(App):
    def build(self):

        return SetIndex()

if __name__ == '__main__':
    MainApp().run()

Very nice ! 

I know that I will be using these widgets.

Thanks.

[Dragos Nicu]

Hi,

Thank you for your response!

The thing is that when I select the date, the text input field is not updated with the selected date. It just shows the hint_text. I don't know how to update the text field after I select the date.

And thank you for spotting the typo! :D

[ngoone...@gmail.com]

This looks great, but when I try to use it in python3 it crashes on import with this error:-

ImportError: No module named 'calendar_ui'

Not sure if you can figure it out.

Hi

I test your module but if i compile with buildozer with android, have no error and a apk.

#    List as sections

#

#    You can define all the "list" as [section:key].

#    Each line will be considered as a option to the list.

#    Let's take [app] / source.exclude_patterns.

#    Instead of doing:

#

#[app]

#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*

#

#    This can be translated into:

#

#[app:source.exclude_patterns]

#license

#data/audio/*.wav

#data/images/original/*

#

#    -----------------------------------------------------------------------------

#    Profiles

#

#    You can extend section / key with a profile

#    For example, you want to deploy a demo version of your application without

#    HD content. You could first change the title to add "(demo)" in the name

#    and extend the excluded directories to remove the HD content.

#

#[app@demo]

#title = My Application (demo)

#

#[app:source.exclude_patterns@demo]

#images/hd/*

#

#    Then, invoke the command line with the "demo" profile:

#

#buildozer --profile demo android debug

Sorry, for this late answer, to  solve that kind of issue I guess you'll just have to add `KivyCalendar` to your buildozer.spec requirements.

Furthermore when you're launching the app you can use `adb logcat` (So the full command with buildozer will be `buildozer android <debug> deploy run logcat`), and as an advice for this

kind of app you can enable Python's logcat filter in your buildozer.spec :)

Hello Oleg,

You've made a great job on this Widget !

I've made some small modifications/improvements on your Widget, and I'd like to know if it's possible to make a pull request on your repository.

I've never used  BitBucket before and I don't know why I cannot fork :/

Is anyone can fork ? Am I stupid  ;p ?

Thank you in advance for your answer :)
