Sliders in pythonista

[Holm]

How do i change the values of a variable in pythonista using a slider

[cvp]

@Holm little example to change the value of the variable x

import ui
x = 0
x_max = 100
def s_action(sender):
    x = x_max*sender.value
    sender.name = 'x='+str(int(x))
s = ui.Slider()
s.action = s_action
s.width = 200
s.name = 'x='+str(int(x))
s.present('sheet')

I built an app and am running this app on my iPad.

The video shows an app with 8 inputs — 2 integer, 4 float, 2 boolean. Numeric input is tedious — at best; slider input is easier and offers positive feedback. In this app, both approaches are used:

Efficient sliders for user input
Only clear text for user screenshots

I enhanced the slider class to allow min values, floats, rounded floats, booleans. Rounded floats allow only multiples of say 0.5 [0.0, 0.5, 1.0, 1.5 ... ] or of 5 [0, 5, 10, 15 ...].

I’ve completed my new app for iPhone and iPad.

Thanks to all.

It would be cool if you could make this a GitHub repo instead of a GitHub gist. That would allow others to suggest improvements in the form or pull requests. For instance:

self.s_type = kwargs['s_type'] if 's_type' in kwargs else 'int'
# could be rewritten as
self.s_type = kwargs.get('s_type', 'int')
