FloatSpin implements a floating point wx.SpinCtrl.
FloatSpin implements a floating point wx.SpinCtrl. It is built using a custom wx.PyControl, composed by a wx.TextCtrl and a wx.SpinButton. In order to correctly handle floating points numbers without rounding errors or non-exact floating point representations, FloatSpin uses the great FixedPoint class from Tim Peters.
What you can do:
import wx import wx.lib.agw.floatspin as FS class MyFrame(wx.Frame): def __init__(self, parent): wx.Frame.__init__(self, parent, -1, "FloatSpin Demo") panel = wx.Panel(self) floatspin = FS.FloatSpin(panel, -1, pos=(50, 50), min_val=0, max_val=1, increment=0.01, value=0.1, agwStyle=FS.FS_LEFT) floatspin.SetFormat("%f") floatspin.SetDigits(2) # our normal wxApp-derived class, as usual app = wx.PySimpleApp() frame = MyFrame(None) app.SetTopWindow(frame) frame.Show() app.MainLoop()
This code snippet can be downloaded, see this example script.
Some of the AGW snippets of code in the documentation use images and external files (to create bitmaps or access external data). As these files are not provided in these snippets, you should make the approriate modifications to the code to actually run it.
FloatSpin catches 3 different types of events:
In addition, there are some other functionalities:
This class supports the following window styles:
|Window Styles||Hex Value||Description|
|FS_READONLY||0x1||Sets FloatSpin as read-only control.|
|FS_LEFT||0x2||Horizontally align the underlying wx.TextCtrl on the left.|
|FS_CENTRE||0x4||Horizontally align the underlying wx.TextCtrl on center.|
|FS_RIGHT||0x8||Horizontally align the underlying wx.TextCtrl on the right.|
This class processes the following events:
|EVT_FLOATSPIN||Emitted when the user changes the value of FloatSpin, either with the mouse or with the keyboard.|
FloatSpin control is distributed under the wxPython license.

Modifications to allow min_val or max_val to be None done by:
James Bigler, SCI Institute, University of Utah, March 14, 2007
Note that the changes I made will break backward compatibility, because I changed the contructor’s parameters from min / max to min_val / max_val to be consistent with the other functions and to eliminate any potential confusion with the built in min and max functions.
You specify open ranges like this (you can equally do this in the constructor):
SetRange(min_val=1, max_val=None) # [1, ] SetRange(min_val=None, max_val=0) # [ , 0]
or no range:
SetRange(min_val=None, max_val=None) # [ , ]
