Advanced cx_Freeze - Using a setup.py File

Explore how to build Python executables using cx_Freeze by writing and modifying a setup.py file. Understand how to suppress the console window in GUI applications and create cross-platform binaries efficiently.

We'll cover the following...

First off we need a script to use. We will use the wxPython form example from the previous chapters.

Python
import wx
class DemoPanel(wx.Panel):
    """"""
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)
        labels = ["Name", "Address", "City", "State", "Zip",
                  "Phone", "Email", "Notes"]
        mainSizer = wx.BoxSizer(wx.VERTICAL)
        lbl = wx.StaticText(self, label="Please enter your information here:")
        lbl.SetFont(wx.Font(12, wx.SWISS, wx.NORMAL, wx.BOLD))
        mainSizer.Add(lbl, 0, wx.ALL, 5)
        for lbl in labels:
            sizer = self.buildControls(lbl)
            mainSizer.Add(sizer, 1, wx.EXPAND)
        self.SetSizer(mainSizer)
        mainSizer.Layout()
    def buildControls(self, label):
        """
        Put the widgets together
        """
        sizer = wx.BoxSizer(wx.HORIZONTAL)
        size = (80,40)
        font = wx.Font(12, wx.SWISS, wx.NORMAL, wx.BOLD)
        lbl = wx.StaticText(self, label=label, size=size)
        lbl.SetFont(font)
        sizer.Add(lbl, 0, wx.ALL|wx.CENTER, 5)
        if label != "Notes":
            txt = wx.TextCtrl(self, name=label)
        else:
            txt = wx.TextCtrl(self, style=wx.TE_MULTILINE, name=label)
        sizer.Add(txt, 1, wx.ALL, 5)
        return sizer
class DemoFrame(wx.Frame):
    """
    Frame that holds all other widgets
    """
    def __init__(self):
        """Constructor"""        
        wx.Frame.__init__(self, None, wx.ID_ANY, 
                          "Py2Exe Tutorial",
                          size=(600,400)
                          )
        panel = DemoPanel(self)        
        self.Show()
if __name__ == "__main__":
    app = wx.App(False)
    frame = DemoFrame()
    app.MainLoop()

Now let’s create a setup.py file in the cx_Freeze style:

Python
# setup.py
from cx_Freeze import setup, Executable
setup(
    name = "wxSampleApp",
    version = "0.1",
    description = "An example wxPython script",
    executables = [Executable("sampleApp.py")]
    )

As you can see, this is a pretty simple one. We import a couple classes from cx_Freeze and pass some parameters into them. In this case, we give the setup class a name, version, description and ...
