py2app?  It's said to be like py2exe.

I know that and I've done it, thanks.

But the point is to make a double-clickable .app bundle for _distribution_ to 
_others_.

Sincerely,

[pygtk] Fileselectors/Aboutbox appearing under dialogs on Windows

2006-10-19 Thread Reidar Strand Hagen 

Hi

Basically, I have two examples inside my program (which runs inside a
standard GtkWindow) which seem broken. A standard Dialog with buttons
which opens FileSelectors, but the fileselectors open *under* the
dialog calling them. Worse, I use the standard AboutDialog, and the
standard license and Credits popups appear under the AboutDialog (one
of them completely hidden). Everything is inited from glade files.

Sorry for not providing example code, but I've been unable to
reproduce this simply, as in all my small test-examples, everything is
working as you'd assume they should..  So basically I was hoping
somebody had encountered this problem before, or atleast could give me
some pointers on what to look for.

Using:
Microsoft XP Prof. w/SP2
Gtk+ 2.8.14-rc1
Python 2.4.3
Glade

regards
Reidar Strand Hagen

I think you need to use different methods on different systems.  So,
what OS is this for?

Yes, you can pass the buffer pointers around. I have done it many times.
No you do not need to make them global.

Updating any gui items from a thread other than the main gui thread is
asking for trouble.  For any thread to safely access the textview buffer
you need to wrap it with calls to gtk to get clearance (sorry, don't
recall the actual function names atm) to modify them without causing
conflicts.  Something that can hold up your thread waiting for the
update to sync with the gui.

A much safer way to go is to gather your info in the threads and then
pass that info back to the main gui thread to update the correct buffer.
A good example of this is using the dispatcher module we've come up with
that handles the inter-thread communication collision free.  see
attached code.  You will see in the example code that the buffer pointer
is passed to the method that appends the text to the buffer.  It should
be easy to modify the example code to use different buffers for each
thread.

I have used global variables in our app which has several notebook tabs
each with their own textview and use the same append method.  I used
global lists to store the buffer pointers and pass the index number to
the append module as there are several other things that use the index
number as well.  Word of caution if you intend on using a list to store
the pointers use the list.append() to add them to an empty list, don't
initialize the list like:

buffer_list = [None, None] # it won't work

buffer_list = [] # works
buffer_list.append(buffer_pointer1)
buffer_list.append(buffer_pointer2)


code snipit:

def append(self, num, text, tagname = None):
""" Append text to a text buffer.  Line numbering based on
the process window line count is automatically added.
BUT -- if multiple text buffers are going to be updated,
always update the process buffer LAST to guarantee the
line numbering is correct.
Optionally, text formatting can be applied as well
"""
#dprint("Notebook: overwrite() -- num= " + str(num))
#dprint(self.current_tab)
line_number = self.view_buffer[TAB_PROCESS].get_line_count() 
iter = self.view_buffer[num].get_end_iter()
lntext = str(line_number).zfill(6) + ' '
if self.last_text[num].endswith('\n'):
self.view_buffer[num].insert_with_tags_by_name(iter, lntext, 
'linenumber')
if tagname == None:
#self.view_buffer[num].insert(iter, text)
#dprint("Notebook: append(): attempting to set text with tagnames " 
+ str(self.current_tagnames))
self.view_buffer[num].insert_with_tags_by_name(iter, text, 
*self.current_tagnames)
else:
self.view_buffer[num].insert_with_tags_by_name(iter, text, tagname)
if self.auto_scroll[num] and num == self.current_tab:
self.scroll_current_view()
self.last_text[num] = text

In the dispatcher example you will see that the method
