Easiest way to load images in wxPython?

sravan953 — Mon, 23 Nov 2009 10:59:21 GMT

Hey All,

I am working on a Java project for school. To make my project better, I wanted to integrate Python into it... like what I wanted to do is:

You run the Python program
You get two options:
a) View source code
b) View output
(Output is a recorded video)
User selects any of the two

So here's the code:

import wx



window=wx.App()



class project(wx.Frame):

    def __init__(self):

        wx.Frame.__init__(self, None, -1, "Sravan's Java Project",size=(500,500))



        self.panel=wx.Panel(self, -1)



        wx.StaticText(self.panel, -1, "Welcome to Sravan's Java Project.", pos=(10,10)).SetForegroundColour('red')

        wx.StaticText(self.panel, -1, "You can:",pos=(10,40))



        wx.Button(self.panel,101,"View source code",pos=(70,100))

        self.Bind(wx.EVT_BUTTON,self.sc,id=101)



        wx.Button(self.panel,102,"View output",pos=(70,160))

        self.Bind(wx.EVT_BUTTON,self.op,id=102)

        

        self.Show()

        self.Centre()



    def sc(self,event):

        wx.MessageBox("Hi")



    def op(self,event):

        wx.MessageBox("Bye")

        

project=project()

window.MainLoop()



# For now, the functions don't actually do anything,

# but I'll fix that later

My question is, I want to put two images of Blue J and WMP at (10,100) and (10,160) respectively. I just wanted to know how to do it...

Need some advice on my topic for Java project...

Hey All,

I have been asked to do a project on Java at school. We are still learning it at an elementary level...

Many decided to do the project on things like ticket booking, banking and stuff... whereas I wanted to do something innovative and so decided that my topic would be on converting some simple Java source code to Python source code...

I need some advice on whether it is is feasible or not...

Cheers

wxPython text overwrite problem...

Hey All,

I have some code here, the problem is in line 82-83:

import smtplib

        try:

            self.s.login(self.user,self.passw)

            wx.StaticText(self.panel,-1,"Logged in...",pos=(10,200))

        except:

        self.message=self.msg_info.GetValue()

        self.msg="To: "+self.to+"\nSubject: "+self.subject+"\n"+self.message

        self.s.sendmail(self.user,self.to,self.msg)

        self.s.quit()        



        wx.StaticText(self.panel,-1,"Your message has been sent!",pos=(175,500))        



pymailer()

window.MainLoop()

- because once I login successfully, if I again login with wrong details, the "Failed" text doesn't overwrite the "Logged in..." text fully.... so what do I do?

Thanks a load

Converting wxPython files to .exe

sravan953 — Mon, 26 Oct 2009 11:58:54 GMT

wxPython, how to retrieve numbers?

sravan953 — Fri, 09 Oct 2009 13:24:31 GMT

Hey guys,

I was just making a tiny program, where I need the user to enter numbers. My question is, how do get numbers?

I tried:

self.panel=wx.Panel(None,-1)

self.n=wx.TextCtrl(self.panel,-1,"Number")

self.get=int(self.n.GetValue())

-but that didn't work... so how do I do it?

wxPython Events help

sravan953 — Tue, 22 Sep 2009 14:50:19 GMT

Hey guys,

I have made a small program called 'Py-mailer' which allows you to login with your Gmail credentials and send text-only messages to anyone. I uploaded it on SourceForge( http://www.tinyurl.com/m4ans4).

The next step I had to take was to make a GUI for it. So, I started with wxPython:

import wx



window=wx.App()



class pymailer(wx.Frame):

    def __init__(self):

        wx.Frame.__init__(self,None,-1,"Pymailer",size=(500,500))



        panel=wx.Panel(self,-1)



        menu=wx.MenuBar()

        items=wx.Menu()

        

        items.Append(201,"Quit")

        self.Bind(wx.EVT_LEFT_DOWN,self.Quit,id=201)



        menu.Append(items,"File")

        self.SetMenuBar(menu)



        wx.StaticText(panel,-1,"Please enter your Gmail login ID: ",pos=(10,10))

        wx.StaticText(panel,-1,"Please enter your Gmail login password:\n(will not be stored)",pos=(10,40))



        username=wx.TextCtrl(panel,101,"Login ID",pos=(220,10))

        password=wx.TextCtrl(panel,102,"Password",pos=(220,40))



        self.Centre()

        self.Show()



    def Quit(self,event):

        self.Close()    



pymailer()

window.MainLoop()

But, on clicking 'Quit' in the 'File' menu, nothing happens! I think it is because in line 29, I have not passed the ID of the event, so how do I pass the ID? Or, is because of some thing else?

Thanks

Program abruptly quits

sravan953 — Sat, 12 Sep 2009 17:07:06 GMT

Hey guys,

I have made a program called 'tLapse', here's the code:

import subprocess

import time

import os



print("Welcome to tLapse...")

time.sleep(3)

os.system('cls')



try:

    com=open("action.txt",'r').read()

    condition=True

except:

    print("File error")

    raw_input("")

    condition=False



if(condition):

    clock=raw_input("Enter time duration after which\nuser-specifiedaction will be\npeformed.\n\nFormat- [hh:mm][24- hour format]: ")



def app(path):

    ext=path[-3:]

    try:

        if(ext=='exe'):

            subprocess.call([path])

        elif(ext=='mp3'):

            subprocess.call(["C:\Program Files\Windows Media Player\wmplayer.exe",path])

    except:

        print("Unexpected error occured")

    raw_input("")



def shutdown():

    os.system("shutdows -s")

    

def determine(com):

    for x in com:

        if(x==' '):

            ind=com.index(x)

            type=com[:ind]

            path=com[ind+1:]

    if(type=='open'):

        return path

    elif(type=='shutdown'):

        shutdown()



path=determine(com)



if(condition):

    print("Waiting till "+clock+"...")

    while(clock!=str(time.asctime()[11:16])):

        if(clock==str(time.asctime()[11:16])):

            os.system('cls')

            app(path)

What it does is, it basically asks at what time the specified action has to be performed(action specified in 'action.txt' file).

But the problem is, even though I give thoroughly valid commands, it abruptly quits without reporting any errors, and sometimes it magically works(like, after running it a few dozen times with the same commands specified in the .txt file).

Any idea why?

Getting variables from other functions

sravan953 — Tue, 08 Sep 2009 12:23:42 GMT

Hey guys,

I have some code:

import urllib2 as url

import subprocess

import os



webs=open("url.txt",'r')

read_webs=webs.read()



def get_html():

    try:

        req=url.urlopen(read_webs)

        res=req.read()

        return True

    except:

        print("")



def get_command():

    if True:

        for x in res:

            if(x!='<'):

                command+=x

            else:

                break

    determine()



command=""



def determine():

    format=command[len(command)-3:]

    print format



get_html()

get_command()

The problem is:

Quote:

>>>
Traceback (most recent call last):
File "C:\Documents and Settings\Sravan\My Documents\Sravan\PYTHON\Accepshun.py", line 32, in
get_command()
File "C:\Documents and Settings\Sravan\My Documents\Sravan\PYTHON\Accepshun.py", line 18, in get_command
for x in res:
NameError: global name 'res' is not defined
>>>

I understand that get_command() doesn't know what 'res' is, but how do I solve this problem?

Searching Weather for a term with urllib2 module

sravan953 — Tue, 08 Sep 2009 07:51:07 GMT

Hey guys,

I am making a program called 'Weather Watch' which basically gets weather updates for any city you type in.

For now, it only gets info for a particular city. I don't know how to search for the term entered in www.weather.com and then get the updates. The code so far:

import urllib2 as url

import os

import time



os.system('cls')



print("[Content provided by The Weather Channel]")

time.sleep(3)

os.system('cls')



print("Please wait...this may take a few seconds.")

time.sleep(3)

os.system('cls')



condition=True



try:

    url_open=url.urlopen("http://www.weather.com")

    lines=url_open.readlines()[1192:1199]

except:

    condition=False



if(condition):

    print("Weather forecast for Bangalore, INDIA\n")

    for x in lines:

        onsplit=x.split(">")



        tags=onsplit[2][:-5]



        if(tags=="Pressure:"):

            data=onsplit[4][:5]

        elif(tags=="Dew Point:"):

            data=onsplit[4][:2]

        else:

            data=onsplit[4][:-5]



        print(tags+" "+data)

    raw_input("\n")

This is what I've learnt on searching for a term in a site[Google, here]

import urllib2 as url2

import urllib as url



values={"search":"city"}



data=url.urlencode(values)



req=url2.Request("http://www.google.com",data)

res=url2.urlopen(req)



print(res.read())

How to use Mozilla's YouTube downloader?

sravan953 — Tue, 01 Sep 2009 15:57:04 GMT

Hey guys,

I am working on a Python project which will enable to watch movies on YouTube easily.

I have added 'YouTube Video Downloader' as an add-on to my Mozilla we browser. Now, everytime I enter a list of URLs containing the movie I want to watch in parts, the program should open the URL, and use the add-on to download the video. How is it possible? I have some basic code here, but have no clue on how to use the add-on

import time

import urllib2

import os



print("Welcome.")

n=input("How many parts are there of the video you want to watch? ")

print("Please wait...")



time.sleep(3)

os.system('cls')



s=[]



for x in range(n):

    s.append(raw_input("Enter URL: "))



os.system('cls')



for x in s:

    urllib.urlopen(x)

Thanks
