Detect Screen Size in Windows Resize Event in WxPython

It has taken a few days to try, redo, restudy, try, redo, restudy repeatingly until just now ... after taken a corn and some snack ....

Here's a sample code ... of course I found the original code from google, and change here and there to get it work.

There are still a lot of things to learn and explore ... am trying to develop my own Project Scheduling Software ... I have started with Java 1.7, but found some bugs that reduce my confidence on it ... so try Python. Although it seems to be easier in syntax, but there are many ways for getting it work as per expected. But, still enjoy the problems ....

Sending email with gmail smtp in Python (it's simple and powerful)

Hi, I found two python code examples and I combine them and it works. Here is the sample code.

 This example send emails using gmail smtp service, so basically it is free and is possible even if you do not have an smtp server in the office :)

Enjoy! Python is powerful :)


Sample Code in Python 2.7:

import smtplib
from email.MIMEText import MIMEText

msg_text = 'my email content is here ... !!!'
msg = MIMEText(msg_text)
msg['Subject'] = 'Hello Subject'

server = smtplib.SMTP( "smtp.gmail.com", 587 )
server.starttls()
server.login('', '')
server.sendmail('', '', msg.as_string() )

print 'email sent successfully ... yahoo!!'

Save above code into a python code file, and then at Dos prompt, type Python example.py for example :)

Sample Python Code: Showing Combobox Selected Text

The following code shows how to retrieve the selected text from wx.ComboBox when a mouse click event is triggered.

------------------------------------------------------------------------------------------------------------------------------
import wx

class MyFrame(wx.Frame):
    def __init__(self, parent=None, id=-1, title=''):
        wx.Frame.__init__(self, parent, id, title,size=(200, 240))
        top = wx.Panel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        font = wx.Font(9, wx.SWISS, wx.NORMAL, wx.BOLD)
        lb = wx.StaticText(top, -1,'static text')
        sizer.Add(lb)

        c1 = wx.StaticText(top, -1, 'Number:')
    self.s1 = c1.Label
        c1.SetFont(font)

        ct = wx.SpinCtrl(top, -1, '1', min=1, max=12)
        sizer.Add(c1)
        sizer.Add(ct)

        c2 = wx.StaticText(top, -1, 'Type:')
        c2.SetFont(font)
        self.cb = wx.ComboBox(top, -1, '',choices=('A', 'B', 'C','D', 'E', 'F'))

        sizer.Add(c2)
        sizer.Add(self.cb)

        showbtn = wx.Button(top)
        showbtn.SetLabel('Show Info')
        self.Bind(wx.EVT_BUTTON, self.ShowValue, showbtn)
        sizer.Add(showbtn)

        qb = wx.Button(top, -1, "QUIT")
        self.Bind(wx.EVT_BUTTON,lambda e: self.Close(True), qb)
        sizer.Add(qb)

        top.SetSizer(sizer)
        self.Layout()

    def TestMe(val, self, e):
        print val
   
    def ShowValue(self, e):
        wx.MessageBox('Show Value ...' + self.cb.GetStringSelection())
   
class MyApp(wx.App):
   def OnInit(self):
       frame = MyFrame(title="wxWidgets")
       frame.Show(True)
       self.SetTopWindow(frame)
       return True

app = MyApp()
app.MainLoop()

--------------------------------------------------------------------------------------------------------------------------
Based on code above, the key part is to declare a self.cb variable to hold a reference to the combobox. This is the easiest way to refer to the combobox.

Of course, this is something I found after I have searched around and tried a few ways ... this is something I figure out when I don't find any specific example after googling :)
