wxPython Grid Cell change question
Hello All, I created a grid, where I register events every time the user changes an existing value inside the grid control. Right now, I am using the event: EVT_GRID_CELL_CHANGE. However, I realized that I need to register that same kind of event even if the user doesnt change the value, but just selects and then deselects. I tried creating my own custom event, where i check to see if the editor is activated and then deactivated, and if so, then set the sell value. However, this doesnt work because the value that it needs to be set to is the same previous value that was in the grid. Therefore, I can never get a new value in the grid. Here is the code for the events: in init(): self.Bind(wx.grid.EVT_GRID_EDITOR_SHOWN, self.EditorShown) self.Bind(wx.grid.EVT_GRID_EDITOR_HIDDEN, self.EditorHidden) def EditorShown(self, event): self.editorShown = True event.Skip() def EditorHidden(self, event): self.editorHidden = True row = event.GetRow() col = event.GetCol() print "VAL = " + str(self.grid.GetCellValue(row, col)) +str(self.OnTestCellValue(row, col)) event.Skip() def OnTestCellValue(self, row, col): if self.editorShown and self.editorHidden: self.editorShown = False self.editorHidden = False self.SetCellValue(row, col) def SetCellValue(self, row, col): print "EVENT PROCESSIGN STARTED" print "RAW VAL = " + str(self.grid.GetCellValue(row, col)) value = int(self.grid.GetCellValue(row, col), 16) print "VAL = " + str(value) # if we need to add a row if row == (len(self.data)-1): self.expandGrid() self.data.append([]) # if we need to delete a row if row != 0 and value == '': self.data[row][3] = 'Delete' else: self.addToData(row, col, value, True) # whether the user intended a read or write if self.data[row][3] != 'Delete': if col == 1: self.data[row][3] = 'Read' elif col == 2: self.data[row][3] = 'Write' q = copy.deepcopy(self.data) # cloning object self.requestQueue.put(q) # putting object onto queue print "EVENT PROCESSIGN ENDED" Thanks a lot for your help, and please mind the spacing. I should note that before, my bind was: self.Bind(wx.grid.EVT_GTID_CELL_CHANGE, self.SetCellValue) thanks, Kiran -- http://mail.python.org/mailman/listinfo/python-list

wxPython Grid XY Coordinates question
Hello All, I am writing an app in wxPython using a grid. I need to be able to recognize what cell in the grid the user is hovering over with the mouse. How to do this? I tried XYToCell(x, y), but that doesnt work properly because it thinks that mouse position (0, 0) is the first cell in the grid, and then goes from there, so if i move the grid to a differernt area on the screen, the XYToCell is messed up in what it returns. Any ideas on how to get this to work or any other way? thanks, Kiran -- http://mail.python.org/mailman/listinfo/python-list
2 timers, doesnt work?
I am creating 2 timers inside a GUI, but it seems that only the one declared last (the second timer), gets triggered, but the first one doesnt. Here is the code for the timers: # main timer, which governs when the register watcher get updated self.mainTimer = wx.Timer(self) self.Bind(wx.EVT_TIMER, self.UpdateAll, self.mainTimer) self.mainTimer.Start(5, False) # graph timer, which governs when the graph gets updated self.grphTimer = wx.Timer(self) self.Bind(wx.EVT_TIMER, self.upGrphDisplay, self.grphTimer) self.grphTimer.Start(101, False) So in this case, only the upGrphDisplay method gets called, the UpdateAll function doesnt get called. Any clues as to why this is happening? thanks a lot! -- kiran -- http://mail.python.org/mailman/listinfo/python-list

wxPython Linux Compatibility question
Hello All, My question is regarding MDI Windows Support for Linux in wxPython. I am currently writing an application which uses MDI. I have seen that in linux, it basically makes all MDI windows tabs (without close, minimize, or maximize buttons and other tools such as cascade and stuff), which is fine by me. I however want to know which MDI window the user has focus of so that the user has an option of closing the window if they so desired under Linux.

return tuple from C to python (extending python)
Hi all, I want to make python call some C functions, process them and
return them.
Ok, I got all the wrapper functions and everything setup right. Here
is my problem. What I need to do is to return a tuple from C to
python.
To go about doing this, I first create a tuple object in C doing the
following:
PyObject* toRet;
toRet = PyTuple_New(num_addr);
then, in a for loop, i assign values to the tuple as follows:
for ( i = 0; i < num_addr; i++ )
{
printf("%d\n", dat[i]);
PyTuple_SET_ITEM(toRet, i, (PyObject*)dat[i] );
}
(dat is declared as follows: unsigned int* dat; )
then, i say return toRet at the end of my C function.
when I try to print the tuple in python, it says the memory address
0x could not be written, and I can see a part of the tuple
printout, which is as follows:
( ,
then i get my error.
can someone please help me with this?
thanks a lot!

Namespace problems
Hello All, I am kind of a beginner to python, but here is the deal. I am writing a wxpython Application, in which I have a GUI. This GUI imports some other modules that I have written, using the format import mymodule as _MyModule Now, this GUI in addition to having all it's bells and whistles has a console (from pyshell), so that the user can run their own scripts inside this GUI. What I am trying to do is to get these scripts that the user runs to be able to see all the other objects created and modules imported by the GUI. To make this clear, what I want to be able to do for example is in my script, do , dir(mymodule), already having imported mymodule in the GUI. Any ideas on how to make this happen? I don't want to import mymodule in this script, i want this script to see the mymodule that I imported in the main GUI. thanks a lot for your help, Kiran -- http://mail.python.org/mailman/listinfo/python-list
Re: Namespace problems
I should note that if you use the execfile command in the console, the script runs, but if you import the script, it says it cant find the module -- http://mail.python.org/mailman/listinfo/python-list
wxPython, tree Control text cutoff
Hello all,
I am using a tree to display stuff, and it is constantly updated, but
what I have noticed is in the lowest level, there is clearly noticable
cutoff of the text I place there. The cutoff is existent even if I do
not update the text inside the tree constantly. It seems that the text
is halfway below where it should line up. I tried placing an image to
see if that would correct it, but it does not. The image is perfectly
lined up, but the text is still misaligned.
Any known issues of this and how to fix it? By the way, it happens in
both Linux and Windows.

convoluted, but the parts where I am setting the text should be

Segmentation fault only on Iinux
Hello All, In my program, I have a main thread which is the GUI (wxPython) and then a thread which goes and reads data from a socket. The reason this is in a different thread is because the data might take some time to come back, and I want to have the GUI to be responsive during this wait. When I run my program in Linux, a segmentation fault occurs. When I run it in Windows XP, it works just fine. The main thing that would be of interest is as follows: The segmentation fault does NOT occur if I disable the threads and read the data all in 1 thread (the main thread [gui's]). This leads me to believe it is some sort of threading problem related to linux. However, I personally dont think that it can be something wrong with my code, since my program runs perfectly fine in WindowsXP. I am also carefully protecting data that my threads share with the MainGUI using a Queue and also a semaphore lock. I know this is kind of hard to answer without any code, but would anybody know of some kind of issue such as this where there is some threading problems with Linux and not Windows. I am happy to send the code to anybody who wishes to see it. I havent posted it here because it is kind of lengthy. Also, I should note that I think we are running Linux Kernel 2.4 thanks a lot for your help, Kiran -- http://mail.python.org/mailman/listinfo/python-list

wx.Yield() during socket timeout
Hello All, I am creating a socket connection in order to read and write to a location. My problem is,the gui becomes unresponsive if the socket times out. I know that a good solution is to have the socket read and write with a thread. However, I have tried this and have a problem where ONLY on linux does the program crash, it DOES NOT crash on windows xp. I have been trying to figure out why for about a week and have just given up. Instead, I am now tryign to use wx.Yield() which will allow the gui to be updated. However, during timeouts, the gui still hangs. Does anybody have any clever ideas on how I could call the function wx.Yield() during a timeout so that the GUI stays responsive? I have already tried timers, and they dont work. thanks for your help, Kiran -- http://mail.python.org/mailman/listinfo/python-list
socket buffer flush question
Hello Everybody! I am writing a networking application in python for a small piece of hardware, in which there could sometimes be timeouts. I am using sockets to communicate to this device. Data that is sent to the device is instructions for that piece of hardware, and data recieved is just responses from that hardware. When a timeout happens, for some reason extra data is stored inside the buffer, so when the timeout is over, that extra data (remember this data is instructions) is executed by the hardware, which I don't want. For timeout purposes, I want the socket to be nonblocking, but at the same time this means that I can't flush the buffer, which I think would solve the problem. I realize this is probably quite unclear, so below is a tcpdump which will explain what I mean. 15:10:37.667963 aurl06f2.39979 > 192.168.128.161.46667: P 481:493(12) ack 481 win 5840 (DF) 4500 0040 090c 4000 4006 599f 8fd1 06f2 c0a8 80a1 9c2b b64b 30c7 9289 a552 55df 8018 16d0 c3ec 0101 080a 0962 a1d9 0008 0e90 0001 f800 0110 15:10:51.107769 aurl06f2.39979 > 192.168.128.161.46667: P 481:493(12) ack 481 win 5840 (DF) 4500 0040 090d 4000 4006 599e 8fd1 06f2 c0a8 80a1 9c2b b64b 30c7 9289 a552 55df 8018 16d0 beac 0101 080a 0962 a719 0008 0e90 0001 f800 0110 15:10:51.108259 192.168.128.161.46667 > aurl06f2.39979: P 481:493(12) ack 493 win 5792 (DF) 4500 0040 5580 4000 3f06 0e2b c0a8 80a1 8fd1 06f2 b64b 9c2b a552 55df 30c7 9295 8018 16a0 dbf5 0101 080a 0008 2465 0962 a719 8000 0001 f800 0110 4d05 15:10:51.108283 aurl06f2.39979 > 192.168.128.161.46667: P 493:565(72) ack 493 win 5840 (DF) 4500 007c 090e 4000 4006 5961 8fd1 06f2 c0a8 80a1 9c2b b64b 30c7 9295 a552 55eb 8018 16d0 cb29 0101 080a 0962 a719 0008 2465 0001 f800 0110 0001 f800 0110 0001 f800 * NOTICE THE EXTRA DATA * 15:10:51.108731 192.168.128.161.46667 > aurl06f2.39979: P 493:505(12) ack 565 win 5792 (DF) 4500 0040 5581 4000 3f06 0e2a c0a8 80a1 8fd1 06f2 b64b 9c2b a552 55eb 30c7 92dd 8018 16a0 db99 0101 080a 0008 2465 0962 a719 8000 0001 f800 0110 4d0d 15:10:51.111760 aurl06f2.39979 > 192.168.128.161.46667: P 565:577(12) ack 505 win 5840 (DF) 4500 0040 090f 4000 4006 599c 8fd1 06f2 c0a8 80a1 9c2b b64b 30c7 92dd a552 55f7 8018 16d0 a867 0101 080a 0962 a719 0008 2465 0001 f800 0114 The last 3 words (32 bits/word) of the hex printout shows the condition.

As you can see, the first 2 printouts are a timeout (it is much longer than this, but i didnt want to post all of that) because one machine is communicating to the other without a response. The third printout is when the machine recovers from the timeout, and it works fine. However, the printout after the machine recovers has some extra data at the end. This is the data I want to flush out of the buffer, but I cant really figure out how to do so.

namespace problems
Hi all, I am trying to get the following to work, but cant seem to do
it the way i want to.
ok, so I come into python and do the following:
>>> x = 1
then, i have a file called test.py in which i say:
print x
Now, after having defined x =1 in the python interpreter, i come in and
say:
import test
it has a problem, which i can understand, because it is in its own
namespace,
but even if i say:
from test import *
the interpreter still gives me the error:
NameError: name 'x' is not defined
the only way i can get it to work is if i say: execfile('./test.py')
how can i get this to work by importing and not execfile?
thanks for your help!

python executing windows exe

Is there a memory leakage in this embedded python code?
Hi All,
I am working on embedded python on C these days. I feel there is a
memory leakage in this code. I have used our own memory pool and all
the python code will use the heap from this memory pool.
RunScript(pScriptName,pFuncName,...)
{
PyEval_AcquireLock()
threadState = Py_NewInterpreter();
PyThreadState_Swap(threadState);
/* Import the script module and run the fnc in that script module */
Pyobject *pModule = PyImport_Import(pScriptName);
PyObject *pFunc = PyObject_GetAttrString(pModule, pFuncName);
/* End running the script and calling the script fnc */
Py_EndInterpreter(threadState);
PyEval_ReleaseLock();
}
Befor running this code i checked my memory heap pool available
memory. Then i called the above function to run my script script1.py.
Script ran succesfully, but after completion of the above fnc, when i
checked the memory there is a huge KB of memory is used by this code.
I have no doubt on my memory pool implementation, bcoz it isworking
from many years.
Now, My doubt is, when i call Py_EndInterpreter at the end does it not
clear the whole memory which was used in executing the script? Or
still the imported stuff from the script1.py is in memory only?
Would greatly appreciate the help

Similarly I will write a wrapper functions for accesing file system, task manegement, memory management. With this abstraction layer, I am simulating my target RTOS on windows [ I am ignoring realtime requirement on windows, I will worry about it once I am done with python porting].

Re: Supported Platforms for Python
Hi there! Our team at IBM are exploring the possibility of implementing one of our products using Python. I had a query in this regard. As per IBM's policy, we list details of platforms that our product works on - including the flavors of OS, the versions supported (and sometimes, even the service packs, if it matters) so that it is un-ambiguous to our customers. As an example, you can have a look at this page. Suppose we are riding on Python (i.e., implementing using Python), we need to tell our customers in similar detail as to what platforms we support our products on. I tried to find information about the platforms on which Python is supported from your page. But, it does not detail the versions of OS supported. In this regard, I have the following questions. Thanks for taking your time to respond. 1. Is this information available somewhere? 2. I was pointed to PEP-11, which documents the platforms that are not supported. So, can we take that all active versions of Python (2.7.3 and 3.3, i believe) are supported on all the OS flavors that Python claims to run on -- unless mentioned otherwise in the PEP-11? 3. Also, regarding the following entries listed in the PEP-11. So, any idea which OSes implement these? Name: Linux 1 (Am guessing its the Linux kernel version 1.0?)

Problem with os.path
Hi All, I have a program which fetches the list of files inside a directory. For fetching this list I am making use of the glob.glob method which takes path as a parameter. For building the path I am making use of os.path.join. My code looks somewhat like this: --- import glob import os path = 'E:\mktrisk\service\marketdata\da' for filename in glob.glob(os.path.join(path,'*.java')): datafile = open(filename,'r').readlines() -- this program works fine when the string 'path' is not too long. When I pass a longer string as path, the program doesn't work. Now I am not sure whether its a limitation with the string class or with os.path.

You will probably want to investigate the "paramiko" package, a pure-Python implementation of the SSH2 protocol. - The fish are biting. Get more visitors on your site using Yahoo!

copying only recent files from one machine to another
Hi Everybody, Iam trying to copy files from one machine to another over SFTP connection. For that Iam using sftp.get & sftp.put methods. Now, I have to copy only recently created/modified files,i.e, based on timestamps from remote machine to my machine. Is there any standard implementation for that in python/paramiko ? If not , can anyone suggest me the efficient method to implement the same. Thanks in Advance, Kiran Kumar - No need to miss a message. Get email on-the-go with Yahoo! Mail for Mobile.
