Python UI

[Bruce Colton]

To do a simple binary branching, I basically lifted the following from SPSS Programming and Data Management, with minor changes.  Now I would like a UI to do the following:  Have a dialog box come up with 5 preset values for the variables: percentage lv11 thru percentage lvl5 that asks the user:  Do you want to change them?  If yes, the dialog box gives user opportunity to type over existing values that are then available within Python, or no, and you are done.  Can I accomplish this using either Tkinter or wxpython?  Thanks.


BEGIN PROGRAM.
import wx, spss
app = wx.PySimpleApp()
dlg = wx.MessageDialog(None, "OK to Run Monthly Statistics?",
                                     caption="Important Question",
                                      style=wx.YES_NO | wx.NO_DEFAULT | wx.ICON_QUESTION)
ret = dlg.ShowModal()
if ret ==wx.ID_YES:
      spss.Submit(["get file='c:/users/bruce/documents/data_xout14_0708.sav'.",
              more spss commands.])
END PROGRAM.

wxPython can handle this (Tkinter could, too, but wxPython is better).  To keep this really simple, there are two possibilities close to what you want.

To present a list of choices the user can select from but not edit individually, use wx.MultiChoiceDialog.  Here's an example I did a few years ago for a class.  It presents a variable list and runs DESCRIPTIVES on it (Now I would do this with the Custom Dialog Builder of version 17, instead.)  Beware of listserver mangling of indentation below.

import wx, spss, spssaux

spssaux.OpenDataFile("cars.sav")
vardict = spssaux.VariableDict(variableLevel=['scale'])
choicelist = vardict.variables
if choicelist:
        app = wx.PySimpleApp()
        dlg = wx.MultiChoiceDialog(None, "Select one or more variables\nfor analysis",
         "Descriptive Statistics", choicelist)
        if dlg.ShowModal() == wx.ID_OK:
            vars = dlg.GetSelections()
        else:
            vars = None

        dlg.Destroy()
        app.Destroy()

        if vars:
            varlist = [choicelist[i] for i in vars]
            spss.Submit("DESCRIPTIVES " + " ".join(varlist))


Another way that allows user editing but leaves you with a single string to parse is to use wx.TextEntryDialog.

app = wx.PySimpleApp()
dlg = wx.TextEntryDialog(None, "some message", "title", "default value", style=wx.OK|wx.CANCEL)

if dialog.ShowModal() == wx.OK:
  <do something>
dialog.Destroy()
app.Destroy()
