Re: [Tutor] Calling variable from two different classes
I want to be able to call a variable from one of my classes to my main class (interface layout) and have it update every minute. I am using Python and wxPython. Is it better to be in the main class and read the variable or should I have the class the variable resides in to send the variable along to the main class? In my interface class I have it as: display = wx.StaticText(self, -1, '', (50, 50)) while the class where the variable is in: data_rate = 5000 and I want to be able to put the value stored in data_rate into display so that I can show it on my interface. And regarding the update per some time, I am looking into the poll command. Is that the direction where I should be heading? (I know updating data_rate won't do anything right now since it's a constant, but it will vary later on... just one step at a time here). ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Auto Refresh
I am trying to read a value in a variable from a different class every time I click on a refresh button for my GUI program. The problem is I am using statictext so when I refresh, it displays the new value on top of the old one. In my main GUI: def refresh(self, event): x = refresh_var() value = wx.StaticText(self, -1, str(x.var_rate)) In my refresh class: class refresh_var(): def var_rate(self): random_var = random.randint(5, 100) return random_var So each time I click on the button, which runs refresh, the new value generated by random.randint will be on top of the old number. Is there any commands I can use to remove the old value that is on the GUI window before I put the new one on there? Or is there a better command/syntax that does the same job? I am ultimately trying to make it so the GUI program refreshes and rereads random_var on a set interval. Can anyone offer any advice on how to do it or any commands I can read up on the Internet? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Auto Refresh
Thank you for the reply, SetLabel is exactly what I am looking for. And yes, you were correct, I just typoed the var_rate() when I was composing the email. So what I did is in my main GUI class: wx.StaticText(self, -1, sampling rate':', (107, 150)) self.rate_status = wx.StaticText(self, -1, '', (190, 150))#just to initialize rate_status to some location def refresh(self, event): x = rate() rate_text = self.rate_status.SetLabel(str(x.rate_var())) and in my class that contains the variable (which will change every so often at the end, so right now I'm modeling this with a random generator): class rate(): def rate_var(self): samp_rate = random.randint(44100, 48000) return samp_rate I want to make it so once def refresh ran, it will continuously update and display the new value in samp_rate in my main GUI at some time interval, say every 10 seconds. I have looked up Timer, but I have not been able to make it work. I looked up the documentation in Python's website to no avail. Can anyone suggeste anything to help me?

[Tutor] Docking Windows using Python
My program will have two windows. I want to be able to dock the two so they are side by side. I am wondering if this is doable in Python. If so, could someone lead me to the right direction on where to look? Thank you very much. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Question on how to open other programs and files
I have a question regarding how to open other programs and files in Python
code. I am creating a simple interface and I want it to be able to open
other files, such as a text file or a pdf file. However, those files are
usually associated with other programs - for instance, gedit for text and
document viewer for pdf (I am using Ubuntu 8.10). What syntax or commands do
I need in order to do so. I've used os.popen in Windows XP and it works
fine, but the same code does not work in Ubuntu. This is the part of my code
that deals with opening files/programs:
def openfile(self, event):
result = os.popen("home/user/textfile.txt")
In the terminal it simply says, sh: home/user/textfile.txt: not found. And I
have already set permissions via chmod +x on the files of my choosing. Any
help would be greatly appreciated.

Re: [Tutor] UPDATED: Question on how to open other programs and files
Re: Question on how to open other programs and files (Alan Gauld)
Sorry for being confusing on my last e-mail. I will try to clarify my
intents a bit further. In short, I want to be able to read the data in the
file as well as launch document viewer in Python. For one of the files I
want to read the data from a Python script that's in the same folder as the
GUI Python script. For the pdf file I simply want to be able to launch
document viewer from Python. I know it is probably a lengthy and demanding
request, but I just want to be able to do both eventually in my GUI program.
I am still very new at Python, and so any help would be very useful for me.
I have tried to look up different tutorials online, but I have not found one
that addresses my issues.
