Re: [pygtk] Use of gtk.threads_enter()
Use gtk.threads_enter() when you are inside a thread to every call to gtk. Use it only in pair with gtk.threads_leave() when you are finished interogating with gtk. Why: Else will the program crash with segfault or X11 async.

[pygtk] PrgressBar
Hi, DeprecationWarning: use GtkProgressBar Any idea why I'm getting this warning, i assume that I shall use gtk.ProgressBar? I'm receiving this earing on the following lines in my code: self.progress.set_format_string(%v %%) self.progress.set_show_text(1) self.progress.set_percentage((size/totsize)) In addition to that the set_percentage method is crashing with a lot of debug msg + a x async message. The set_percentage is called within a thread. And yes, I'm using gtk.threads_enter, gtk,threads_leave around it. I've also initialized gtk threads. The same applies for the progress.update and progress.set_fraction. I appreciate very much any ideas regarding this matter.

Say I have: -|--| one | four | -|--| two | five | -|--| three| six | And I wanted to give each cell a different colour (based on its contents or cell data.) How would I do it? CellRendererText seems to apply the background/foreground colours to the whole column. Do I need to implement my own cell renderer? I may be able to do it with treeview.get_cell_area, but I'm not sure how to pass in the GdkRectangle argument. Simply create a column in your model of type string which contains the colour you want for the cell. Then when setting up the tree view column, map that column to the cell_foreground or cell_background properties of the cell renderer. Hi, I wondered about the same thing some weeks ago. Sorry for being silly, but I don't understand how that method is going to give you different colors in individual cells and not just alter the colors in different columns.

Re: [pygtk] pipe.read - interrupted system call what's the story?
I asked the same question a week ago or something. I was receiving IOError, errno 4 when I was using pipe.readlines() together with pygtk. However the solution that solved my problem was to wait for the to finish before a was reading its output. I have actually never seen this problem using popen2 and read one line at the time.

[pygtk] IOError: [Errno 4] Interrupted system call
Hi, I'm getting some strange behaviour when i'm trying to use either os.popen m popen2.Popen3 or popen2.Popen4 in my pygtk programs. Occasionally i'm receiving IOError: [Errno 4] Interrupted system call when i issue the readlines() call on fromchild descriptor, or reads from the fd that comes from fd.os.popen(cmd,'r'). Trying this code standalone, i.e. not pygtk they works fine each time. When i run the code from hitting a button in a libglade, pygtk program i receive this weird behaviour. Anybody have a clue. Thanks for all feedback. Best regards Øistein Aanensen ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
