[pygtk] Passing self.wTree to other classes? Good Idea? - Continued
Sorry, Pressed send by accident. Continuing. I sent en example of my main.py file.. that initialized other classes in other files and just passed the self.wTree to these classes.. Here is an example of my other class that is getting the wTree object passed to it. class Database_Settings: def __init__(self,wTree): #The main gtk wTree was passed from the main (REQUIRED) self.wTree = wTree >From here I can just access objects from other files / tabs. My question is, is this the right way to do this? or are there better ways to allow other classes / files access widgets in the same glade file? Thanks, and sorry about the email in 2 chunks. -- Riley Porter Network Security Engineer Offensive Security - OSCP SANS GIAC - GCIH CCNA, Security+ ACSA - Arcsight Security Analyst ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
[pygtk] Passing self.wTree to other classes? Good Idea?
Hello All,
I recently began using PyGTK + glade to begin work on a project that will
require multiple developers to contribute code to their "sections". What I
mean by this is say the app has a window and it has 1 notebook with 5 tabs
in it. Each developer would be in charge of maintaining his / her tab.
That being said each of the tab's widgets would eventually start to work
together. meaning tab1 might find available hosts on a lan.. tab2 might get
the hosts discovered in tab1 and ping them.. or whatever..
I currently am basically passing having one main file that initializes other
classes in other files and passes self.wTree to each of the following files
so that they all can interact with widgets on different tabs (that are being
used in different source files)
I know I am not making this very clear but here is an example of what I am
doing.
main.py
try:
import pygtk
pygtk.require("2.0")
except:
pass
try:
import gtk
import gtk.glade
except:
print "Failed to load needed gtk libs"
sys.exit(1)
class Log_Viewer:
def __init__(self):
classes = ["manual","parser"]
self.gladefile = "logview.glade"
self.wTree = gtk.glade.XML(self.gladefile)
self.window = self.wTree.get_widget("MainWindow")
"""
Set Status Bar
"""
statusbar = self.wTree.get_widget("STATUSBAR_Main")
STATUSBAR_TXT = statusbar.push(1,'www.Synthetos.com')
self.wTree.signal_autoconnect(self) #Connect all signals to their
corresponding functions with the self object
#Initialize All Classes
Manual.Manual(self.wTree)

You passed io_add_watch a class method as the callback - the first arg
of the classmethod must be self so prepend self to the method definition
params:
def read_output(self, source, condition):

[pygtk] TreeView/cell/signals
... the same problem, a different point of view... If I enter a CellRendererText in editing mode I can press return and the mode switched and signal 'edited'is emitted. Who is responsable for that? I guess is the editable as I can't imagine anything else... but how can I be sure? I mean is there a way to "listen all signals" and who is emitting them? Which is the signal emitted? What can I do from within the 'edited' callback to stop switching from editing mode? sandro -- Sandro Dentella *:-) http://sqlkit.argolinux.orgSQLkit home page - PyGTK/python/sqlalchemy ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
Re: [pygtk] Updating a TextBuffer line by line
Ok, I tried that, but it's giving an error about the number of
arguments sent to read_output. "TypeError: display_details() takes
exactly 2 arguments (3 given)"
Here's my code:
--
gobject.io_add_watch(command.stdout, gobject.IO_IN | gobject.IO_HUP,
self.read_output)
def read_output(source, condition):
if condition == gobject.IO_IN:
line = source.readline()
self.txtbuffer.insert_at_cursor(line)
if condition == gobject.IO_HUP:
self.txtbuffer.insert_at_cursor("Command finished.")
return False
return True

Any ideas on why this is occurring?
Avast!

This sentenced induced me to think that "stop_emission" could be used always
while return True only by those signals that support it.
On the contrary in the following example I try to stop emission of
key-press-event from within the 'edited' callback back to the treeview
callback and it seems not to work.
I connected with Tab from the treeview a callback that shiftws the cell to
be edited, but I'd like to stop it under some conditions from within
editabel callback. it's enought to "return True" (Line 59) and it works
but it does not work instead the line:
self.treeview.emit_stop_by_name('key-press-event')
Did I mis-interpret the signal?

Re: [pygtk] Updating a TextBuffer line by line
Try calling the main loop. Since you are always waiting for the process to send you more data, the GUI does not get a chance to update itself. The insert_at_cursor will insert the text, and cause a redraw event will be send. You can use gtk.main_iteration() to force the event to be processed immediately. Here is what your loop should look like: while command.poll() is None: line = command.stdout.readline() self.txtbuffer.insert_at_cursor(line) while gtk.events_pending(): gtk.main_iteration() Hope it helps, Laszlo 2009/1/22 Daniel Roesler : > Howdy again, > > I am running into a problem displaying stdout from a subprocess > command.

[pygtk] Updating a TextBuffer line by line
Howdy again, I am running into a problem displaying stdout from a subprocess command. I have a loop that checks to see if the subprocess is still active, then reads a line in from stdout and sends it to the text buffer. However, I can't seem to get my text buffer to print except when the command ends. Obviously, I'm missing some logic behind how loops work with pygtk. Here's my code: --- command = subprocess.Popen(cmd, stdout=subprocess.PIPE) while command.poll() is None: line = command.stdout.readline() self.txtbuffer.insert_at_cursor(line) --- Any ideas on how to read stdout line by line with subprocesses?
