Maybe call item.children() and see what is in there? IIRC, the item is
just a GtkBin, and it holds a widget of sorts. Look in there; most
probably you have a label.

[pygtk] getting the text from a ListItem

[Rajarshi Guha]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I have GtkList containing a number of GtkListItems. I've attached a function 
that is connected to select_child signal - the function then recieves a 
GtkList instance. Using get_selection() I get the GtkLIstItem - but I cant 
see how to extract the text from the GtkListItem instance

Can somebody point out how to do it?

[pygtk] Is anybody working on PyGtkScintilla2 ?

[Ahmad Baitalmal]

Scintilla 1.48 has been GTK2 enabled for a while now, and 1.49 now supports Unicode.

Only the port of the wrapper GtkScintilla to GTK2 is needed and we are in business.

Anybody already working on that ?

Some folks might find it does not work, I had tried this  few weeks ago
and it worked up to about the same size as the  tag in pango, after
that the fonts dropped to about 1-2 points.  After upgrading to a later
GTK snapshot this has been fixed.

One thing I liked a lot with Freetype (and PyFT) was the ability to
generate correctly anti-aliased letters on transparent background.
This helped for later GIMP montage, and printing at good resolution,
without too apparent loss of quality.  If I remember well, I chose to
defeat the outline caching in PyFT, because it was not very likely that
I use the same letter twice at the same size and in the same orientation.

This was for generating the labels (I'm not sure of the English word,
I really mean the papers to contain the art work) for a CD-ROM and its
plastic box.  I used PyFT with PIL (Python Imaging Library), but not in
`pygtk' context, so even if my two programs are not big, I'm hesitant
cluttering this mailing list with them.  Just ask me if you think they
could be useful as examples.  I'm not even sure they would work with the
most recent releases of Freetype and PyFT...

a) you didnt import pygtk

No; you should set PYTHONPATH to

/usr/local/lib/python2.2/site-packages/gtk-2.0/

If you want "import gtk" to work straight away.  I *think* that if you
do:

PYTHONPATH=/usr/local/lib/python2.2/site-packages/

Then the following:

import pygtk
pygtk.require("2.0")
import gtk

Might work.

Yes, it does. If you set pythonpath to "/usr/xxx" it will look first in
/usr/xxx, and then in the default system path. To debug these things,
use:

strace -eopen python xxx.py

And look at the open() system calls.

Jay, did you manage to get it working? 1.4.4 should support parallel

I'm working on one. Would you like to help specify the API? I'm thinking
about using Validation objects that specify how you would like to
validate the entry; if you want masks, and so on. You could reuse the
validation object for as many entries as you like, and so on.

Dear 
list-readers,
 
I 
discovered that pango's markup language also allows exact font 
setting.
Setting the string to: 'Blue text has size 38!' sets 
text to font 38.
By the
