wx.SpinCtrl for Floats?

wxPython Users
1

Hello Rich,

My reading and testing confirms that a wx.SpinCtrl will work only with
interger numbers. I have an input variable that can vary from 0.00-1.00 by
hundredths. Is there a widget that will scroll through the values from

0.00,

0.01, 0.02, etc. to 1.00? Or, is my only option to have the user enter it
manually?

What about FloatSpin:

?

I have written it about 1 month ago, it should do the job for your request.

Andrea.

Andrea,

   Wow! What will I need next month? :slight_smile:

   Many thanks. This is just what is needed.

Andrea,

   Super kewel! Two issues to report:

   1) When I add 'extrastyle=FS_LEFT' python complains about no global
variable called 'FS_LEFT'.

   2) I define 'initial=0.20' but the low value (0.00) is displayed instead.

   It's certainly a great widget and I applaud your efforts and thank you.

Rich

Hello Rich,

   1) When I add 'extrastyle=FS_LEFT' python complains about no global
variable called 'FS_LEFT'.

Mhm... it depends on how you actually import the module and you call it, I
think. In the demo, I do:

import FloatSpin as FS

Then:

self.floatspin1 = FS.FloatSpin(self.mainpanel, -1, min=0, max=1,
                                       increment=0.01, value=0.1,
extrastyle=FS.FS_LEFT)

Notice that the "extrastyle" parameter is called with FS.FS_LEFT. If you
want to call only "FS_LEFT", I think you should import the module as
follows:

from FloatSpin import *

But I wouldn't recommend it, it import a bunch of things in your scope.
However, it much depends on your Python style.

   2) I define 'initial=0.20' but the low value (0.00) is displayed

instead.

Yes, you are right. Actually, the "initial" parameter is quite useless (it's
never used in the code), so I have eliminated it. If you want to set the
initial value for FloatSpin, just pass it as parameter, like:

self.floatspin1 = FS.FloatSpin(self.mainpanel, -1, min=0, max=1,
                                       increment=0.01, value=0.1,
extrastyle=FS.FS_LEFT)

Here, value=0.1 is also the starting (initial) value. I have re-uploaded the
new version in the usual place:

http://xoomer.virgilio.it/infinity77/eng/freeware.html#floatspin

   It's certainly a great widget and I applaud your efforts and thank you.

Thanks a lot for your comments and thank you to have tried the demo :wink:

Andrea,

   OK. That's my error. I forgot the namespace designator.

(it's never used in the code), so I have eliminated it. If you want to set
the initial value for FloatSpin, just pass it as parameter, like:

   Oh.

self.floatspin1 = FS.FloatSpin(self.mainpanel, -1, min=0, max=1,
                                      increment=0.01, value=0.1,
extrastyle=FS.FS_LEFT)

Here, value=0.1 is also the starting (initial) value. I have re-uploaded the
new version in the usual place:

   OK.

Thanks a lot for your comments and thank you to have tried the demo :wink:

   I've brought it into the application directory and am using it in my code.
I'll grab the latest version and change the calls to show the initial value.

Thanks,

Rich
