[pygtk] How do I get the previous gtk.TreeIter in a TreeModel?

[Rich Burridge]

Hi,

Hopefully I'm missing something obvious.

Given a gtk.TreeIter in a gtk.TreeModel, from:

http://www.pygtk.org/docs/pygtk/class-gtktreemodel.html#method-gtktreemodel--iter-next

I can see how to get the gtk.TreeIter pointing to the next row.
But how to I get a gtk.TreeIter pointing to the previous row?

Just in case I'm taking the wrong approach here, what I want to do is move
one (or more) selected rows, up one row.

I was expecting the code for the callback for the "Move up one" button
to be something like:

   def textMoveUpOneButtonClicked(self, widget):
   textSelection = self.getTextAttributesView.get_selection()
   [model, paths] = textSelection.get_selected_rows()
   for path in paths:
   iter = model.get_iter(path)
   prevIter = model.iter_prev(iter)
   model.swap(iter, prevIter)

but there is no gtk.TreeMode.iter_prev() function.

Re: [pygtk] accessibility mystery

[Rich Burridge]

Hi Dusty,


Any ideas why some apps are noticed and some are asleep?


See:

http://developer.gnome.org/projects/gap/guide/gad/

which is a little dated now. 


The key is in the following paragraph:

   The implementation for the GTK widgets is in a module called
GAIL (GNOME Accessbility Implementation Library), which is
dynamically loadable at runtime by a GTK application.  Once
loaded, those parts of your application that use standard GTK
widgets will have a basic level of accessibility, without you
having to modify your application at all.  (If GAIL is not
loaded, GTK widgets will have a default accessibility
implementation that essentially returns no information, though
it nominally conforms to the ATK API.)  Applications which use
Bonobo controls, particularly out-of-process ones, also load
accessibility support code from module "libgail-gnome".  Whether
or not applications on the GNOME desktop automatically load
these accessibility support libraries depends on the value of a
gconf key, "/desktop/gnome/interface/accessibility"; a boolean
value of "true" enables support for assistive technologies and
applications which call gnome_program_init will automatically
load the appropriate accessibility libraries at runtime.  "Pure
GTK+ applications", e.g. those that use gtk+ but do not link to
libgnome, rely on the value of the GTK_MODULES environment
variable, which must be set to "gail:atk-bridge" in order to
enable assistive technology support.

Hi Dusty,


Thanks Rich, I think that's exactly the start I'm looking for. I
notice it uses bonobo to access the registry, does this mean gnome
must be running? 



Not the whole of GNOME. I've run AT-SPI programs under CDE, the
other operating system that comes standard on Solaris, and they've
worked fine.

There is going to be a minimal set of applications/daemons that
you will need to have running. at-spi-registry for one.
bonobo-activation for another. To get the definitive set, I suggest
asking on one of the GNOME accessibility mailing lists.


Since I'm running firefox, I assume this means I have to enable
"something else" to get the registry to recognize the applications
available? 



We are working with firefox engineers to make sure that this fully
understands AT-SPI as well. It's early days yet. When we finished,
this should be just another application that accessibility software
can "listen in on" and respond to. StarOffice/OpenOffice will be
others.

Thanks (and to Germán who also mentioned it).




  "import pygtk"  External



You also have: gtk.keysyms, gtk.gdk and gtk.compat (for some 
compatilibity with ancient versions)


Not needed, only a wrapper for handling multiple installed versions.

Note that some parts of the documentation still needs to be written,
atk is completely missing for instance.


Okay.


What I don't seem to be able to find is the equivalent for PyORBIT
or gnome-python. I've just downloaded the source tarball at:



There's as far as I know no documentation for gnome-python or pyorbit.

The easiest way to get a list of APIs is to write a script which goes
through all the modules and introspects them (using 
dir/getattr/isinstance).


Thanks. Germán can up with something else that I think will work nicely:

I will also be able to do this for the PyGtk doc and bring it all
into files in the architecture project case directory (thereby making
a snapshot of the actual documentation).

[pygtk] Re: ANNOUNCE: GnomePython 2.12.1

[Rich Burridge]

Hi.

We (Sun Microsystems) are in the process of integrating PyORBIT, PyGtk and
gnome-python into our next major Solaris JDS (GNOME) release. One of the
steps in order to achieve this is to get the project reviewed by an
architectural review committee. The committee has a "20 questions" document.

One of the questions is:

 9.2   Interface Table: Include Imported and Exported Interface Tables
  showing all customer-visible interfaces and inter-project
  interfaces and significant internal interfaces (inter-subsystem
  and inter-invocation).  Interfaces are not just function calls.
  Include user interfaces (graphical, browser based, character based),
  configuration files, XML schemas, network protocols, port numbers,
  etc.

Now for Pygtk I can put something like:

EXPORTED INTERFACES:

Proposed Former Stability
Interface   StabilityClassification
NameClassification   or Other Comments
-

  "import atk"External   Pygtk imports [1]
  "import glade"  External
  "import gtk"External
  "import gobject"External
  "import pango"  External
  "import pygtk"  External


 [1] PyGTK 2.0 Reference Manual
 http://www.pygtk.org/pygtk2reference/index.html

This is because Pygtk has been extensively documented.

What I don't seem to be able to find is the equivalent for PyORBIT
or gnome-python. I've just downloaded the source tarball at:

http://ftp.gnome.org/pub/GNOME/sources/gnome-python/2.12/

and this just seems to contain some examples and tests. The
README is also a zero-length file.

Could you point me in the right direction for the gnome-python (and
PyORBIT) documentation please?

Thanks.

 - gnomecanvas
 - gnomevfs
 - gconf
 - bonobo, bonobo.activation, bonobo.ui

Thanks, I'll adjust accordingly.




Are you sure that searchStr is in buffer?



No it wasn't. In fact, nothing was in the text buffer. Here was the code 
I had:


   buffer = gtk.TextBuffer()
   highlightText(buffer, searchStr)
   buffer.set_text(results)
   self.result_view.set_buffer(buffer)

A quick reordering of those lines fixed the problem.

[pygtk] Highlighting all occurances of a string in a TextBuffer

[Rich Burridge]

Hi all,

I'm trying to write a function that will highlight all occurances of the
string searchStr in the TextBuffer buffer. This is what I've currently got
that doesn't work.


def highlightText(buffer, searchStr):
buffer.create_tag("red_foreground", foreground="red")
start, end = buffer.get_bounds()
finished = False

while finished == False:
res = start.forward_search(searchStr, gtk.TEXT_SEARCH_TEXT_ONLY)
if not res:
finished = True
else:
matchStart, matchEnd = res
buffer.apply_tag_by_name("red_foreground", matchStart, matchEnd)
start = matchStart


What's happening is that:

res = start.forward_search(searchStr, gtk.TEXT_SEARCH_TEXT_ONLY)

is always returning None.  Any clues to what I'm doing wrong would be
appreciated, or a pointer to some other Pygtk code that does something
similar.

Thanks.
