Window sizing

[John Boyd]

Hello,

I wrote the following script which has two textinputs in a vertical boxlayout.  I am trying to set app window only large enough to contain the textinputs.

import kivy
kivy.require('1.10.1')


from kivy.core.window import Window


from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput


mainframe = BoxLayout(orientation='vertical',
                      size_hint=(None, None),
                      size=(200,200))
tablename = TextInput(multiline = False)
fieldname = TextInput(multiline = False)


mainframe.add_widget(tablename)
mainframe.add_widget(fieldname)


class Test(App):
    def build(self):
        return mainframe
   
Window.fullscreen = False
Test().run()

Unfortunately I am unable to change the size of the apps window. 

I tried at the top of the script :

from kivy.config import Config 
Config.set('graphics', 'width', '200') 
Config.set('graphics', 'height', '200')

And I tried :

Window.size = (200,200)

just before the Test().run() command.

Nothing works.

Any help will be appreciated.

Best Regards,

John.

NOTE: Running Kivy 1.10.1 in a virtualenv on Ubuntu 18.04.1 LTS.

Hello Srinavas,

Thanks for the reply, unfortunately I tried both suggestions in the link and none worked. 

In my search I did find that link before posting here.

Best Regards,

John.

Hello,

You have to configure the graphics before you import the Window class, because when you do, the size of the window is reset.

Something like this:

import kivy

kivy.require('1.10.1')

from kivy.config import Config 

Config.set('graphics', 'width', '200') 

Config.set('graphics', 'height', '200')

from kivy.core.window import Window

# Remaining code…

Regards.

Hi J34n,

That was one of the first things I tried. However I finally got it to work by doing the following:

# Set up the required Window size.
from kivy.config import Config
Config.set('graphics', 'window_state', 'visible')
from kivy.core.window import Window
Window.fullscreen = 1
Window.size = (200,60)

And the final full script:

import kivy
kivy.require('1.10.1')

# Set up the required Window size.
from kivy.config import Config
Config.set('graphics', 'window_state', 'visible')
from kivy.core.window import Window
Window.fullscreen = 1
Window.size = (200,60)

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput

#from kivy.core.window import Window

mainframe = BoxLayout(orientation='vertical',
                      size_hint=(None, None),

                      size=(200,60))

tablename = TextInput(multiline = False)
fieldname = TextInput(multiline = False)


mainframe.add_widget(tablename)
mainframe.add_widget(fieldname)


class Test(App):
    def build(self):
        return mainframe
   

Test().run()

The window opens to the top left corner so I now have to figure out how to get it to the center of the screen.

Thanks for the help and feedback.

Hi all,

Issue solved, I realized my default config.ini was different from standard install. So I reinstalled kivy, and now these three lines at the top works

and the window is centered in the screen:

from kivy.config import Config
Config.set('graphics', 'width',200)
Config.set('graphics', 'height',60)

Thanks again.
