Use of while(1) with app.mainLoop of wxpython
Dear All, I've have created a GUI (using wxPython widgets) where in I've a message log window (A TextCtrl window). I've a router.dll that helps me putting in message onto a channel. In my script that generates the GUI, I want to continuously poll the channel and populate the messages from the channel to the message log window. For this I've to put a while (1) loop, but when I do this, the GUI doesn't come up. I see the GUI coming when while(1) is removed. Is there any issue with usage of app.mainloop and while(1) together. Quick help would be really appreciated. Thanks & Regards, Tarun -- http://mail.python.org/mailman/listinfo/python-list
Issue with wxPython GUI
Hi All, I've a probelm and solution for it to build the preface. Below it is the new problem I'm facing. Can someone help me out? *Problem:* I've have created a GUI (using wxPython widgets) where in I've a message log window (A TextCtrl window). I've a router.dll that helps me putting in message onto a channel. In my script that generates the GUI, I want to continuously poll the channel and populate the messages from the channel to the message log window. For this I've to put a while (1) loop, but when I do this, the GUI doesn't come up. I see the GUI coming when while(1) is removed. Is there any issue with usage of app.mainloop and while(1) together. *Solution: *I used: self.Bind (wx. EVT_IDLE, self.OnIdle) And in the OnIdle function, I check if the data is available on the channel. Referred: http://wiki.wxpython.org/LongRunningTasks *New Problem: *I am opening and executing a script from the GUI. The script has a many log messages, which it posts on some shared memory. The GUI reads the messages from the shared memory, in the Idle loop. But the script is huge and so the logging is not run-time. Rather this happens only after the script has executed. Moreover, the GUI becomes un-responsive till the script has completely executed. Do you have any suggestions for this? Thanks & Regards, Tarun -- http://mail.python.org/mailman/listinfo/python-list
Re: Issue with wxPython GUI
Hi Laszlo Nagy, Thanks a lot. But the issue over here is that how will the child thread acknowledge the main thread that it has completed its task. For this I'll have to set some flag in the child thread and poll for it in the main thread. This will create a problem. Any alternatives??

Creation of multiple threads
Hello All,
I got the following example from
*http://wiki.wxpython.org/LongRunningTasks*<http://wiki.wxpython.org/LongRunningTasks>
This example shows how a worker thread can be created from the main GUI and
the main GUI is notified when the worker thread has done its work..
But my requirement is:
I want to have two worker threads and each one notifies the main thread. It
could be possible that when a worker thread is running, other might be
tirggerd.
1) Can I do with only one Worker thread class?
2) Can there be only one notification function for multiple threads.

Issue with docking wx.listctrl window
Hello All,
I'm trying to create a Frame with AuiManager. The code is attached.
*Problem:*
- I want 2 windows to be docked in the frame. One is a text control and
other is a list control.
- The text control gets docked, but on trying to dock the list control, all
the tabs dis-appear.
The tabs appear only when the list control window is kept floating.
In the attached code the list control window is kept floating. This can be
docked
To see the issue with docking, comment line 33 and un-comment line 35 in the
attached file and then try to execute, the issue would be clearly visible.
On un-docking the window1, the tabs again appear..
*Please let me the solution to this ASAP*

Re: [wxPython-users] Issue with docking wx.listctrl window
Thanks a lot Robin.
I tried using self.log and instead of self.log.list. *Code is attached.* But
this gives me a panel and listctrl in it. The extra blank space around the
listctrl in window1 is something that I don't need.
Please help.

wx.EVT_TREE_ITEM_RIGHT_CLICK. And in this function, I say
self.tree.SelectItem(evt.GetItem(),True) to select the item and then so some
action for right click.

Python Query: Related to locking a resource in a multithreaded environment
Hello All, I've a configuration.ini file. This particular can be accessed by several threads of my application. Each thread can read/write configuration parameters from/to the configuration.ini file. I am using threading (Rlock) to lock the resource (configuration.ini file) while accessing it from any thread. I use the file available at http://www.voidspace.org.uk/python/configobj.html for read/write. I did the following in one of my files: import threading class Synchronization: def __init__(self): self.mutex = threading.RLock() Now this I can create instances of the class Synchronization and use acquire/release to work on the shared resource. But every thread would need to import this class and hence each thread would create a separate instance of the class. This means several lock variables. But I think we need a global lock flag that is accessible across all the threads. How do i do this? Please let me know ASAP. Thanks In Advance, Tarun -- http://mail.python.org/mailman/listinfo/python-list
Re: Python Query: Related to locking a resource in a multithreaded environment
I think I need something called global interpreter lock which is accessible to all the threads. But I am not sure how to implement this.

Code for locking a resource
Hello All, I've a configuration.ini file. This particular can be accessed by several threads of my application. Each thread can read/write configuration parameters from/to the configuration.ini file. I am using threading (Rlock) to lock the resource (configuration.ini file) while accessing it from any thread. I use the file available at http://www.voidspace.org.uk/python/configobj.html for read/write. (configobj.py) I've used RLock to lock the resource. I see this error while accessing variables of the configuration.ini file Exception in thread Thread-3: Traceback (most recent call last): File "C:\Python25\lib\threading.py", line 460, in __bootstrap self.run() File "F:\abc.py", line 229, in run option1 = conf['OPT1'] File "F:\configobj.py", line 551, in __getitem__ val = dict.__getitem__(self, key) KeyError: 'OPT1' Exception in thread Thread-1: Traceback (most recent call last): File "C:\Python25\lib\threading.py", line 460, in __bootstrap self.run() File "F:\def.py", line 130, in run option2 = self.conf['OPT2'] File "F:\configobj.py", line 551, in __getitem__ val = dict.__getitem__(self, key) KeyError: 'OPT2' Can any one help me with a code for locking a resource across threads. One more observation. I tried the following code on Python Idle >>> import threading >>> threading.RLock() <_RLock(None, 0)> >>> threading.Lock() Why does threading.RLock() return None Thanks In Advance, Tarun -- http://mail.python.org/mailman/listinfo/python-list
Regarding subprocess module
Hello all,
I wrote the following code:
import subprocess,time
cmdExe = "C:\\WINDOWS\\system32\\cmd.exe"
myProcess = subprocess.Popen(cmdExe,stdin=subprocess.PIPE)
time.sleep(2)
myProcess.stdin.write('cd Desktop\r\n')
I copied the above lines of code to a file and tried executing the python
file from dos box (command prompt) on windows
I want subprocess.Popen to open a new dos box. But it works in the same
window. What should I do to open the subprocess in new window?
Thanks & Regards.

Oh, My apology ! I should have mentioned the system stats in mail. Windows 7 , 64 bit Intel Core 2 duo C drive free space : 23 GB Initially, during installation system is asking for service pack 1 I did that. Later, it's asking for core.msi, dev.msi etc. Because system is not able to fetch from the web. The log file contains all these errors.

The only demos i have from the paramiko library use a hostkeyfile. since i don't have that i thought i would use the get_remote_key to get the key and then connect it using the code in the demo.. But clearly nothing is working...I should not HAVE to use the key since i should be able to authenticate using the password... Can you please suggest the right way to go ?

RE: paramiko
I have some code that uses paramiko, establishes an SFTP connection with a remote server and downloads some files. This code works perfect if run on a windows XP machine. However, I get an error in the "RandomPool" class. Anyone tried paramiko on a windows server box ? Thanks !!

Also, why are you passing this magic value "15" to event.wait() ? That parameter is passed to class _Verbose to indicate if debug messages should be displayed or not, so typical values would be 0/1 or False/True. -- -- Guilherme H.

Paramiko bugs out on windows 2003 server
I am using the paramiko library to pull a data from a server using SFTP.
It works perfect on a windows xp machine but bugs out a windows 2003
server. I get the following error:
Traceback (most recent call last):
File "S:\Temp\ftpBOA.py", line 5, in ?

raise ImportError("Cannot find OS entropy source")
ImportError: Cannot find OS entropy source
Anyone knows how to solve it ?
