Re: [pygtk] Turning the PyGTK+ brand into something more than it currently is
Hi to all, After a long time I'm back on python and gtk. I'm using gobject and I like it a lot... I totally agree with Rafael; we must start contributing to the Python GTK+3 in order to have a guide as complete as the one for pygtk. The second step can be to help Dieter as beta tester with his effort on windows... To have a good support on windows platform is essential and ca be the key feature If we create an hype on giobject, people will expect to have at least the same level of functionality and documentation of pygtk... Just my 2 cent Thanks !

I think the stupidest mistake in recent times was calling it pygobject and not inheriting the pygtk name (and I objected strongly at the time too). I think we can still change our mind here. But more worryingly, I am not confident promoting pygobject as a replacement for pygtk unless it (and gtk+g-i) is supported on windows. In my experience, in the scientific computing sphere, people still use pygtk/gtk2 because it works on windows, gtk3 gets destroyed by qt for the same reason. I don't really know what to do thought. John Same feeling here. PyGObject is now alreay useful for people writing Linux only code, but without good win32 support it won't replace PyGTK for a vast majority of users that either want a cross platform solution or need to run their apps also on windows. IMHO that's the problem with PyGObject, not the brand. But, perhaps, a more prominent section about PyGObject could be added to the www.pygtk.org website. Dieter Verfaillie has beeing doing a lot of work to get Python + GTK+ 3 working on windows and he even has a experimental version for win32 that works but still nees more work to be generally useful. He wrote a report on his work here http://article.gmane.org/**gmane.comp.gnome.gtk%2B.** python/16049http://article.gmane.org/gmane.comp.gnome.gtk%2B.python/16049and this means that the remaining work needs to focus on Glib (object-introspection) and GTK+, as PyGObject is apparently working fine on win32. So, to improve windows support more volunteers are needed, with enough patience to find out and understand what's missing. Meanwhile, the pygtk.org website is kept alive for those that can't migrate to pygobject, even if no development effort is being done now on PyGTK. We are doing small updates from time to time and the website is still somewhat active (you can find updated PDF and html versions of the docs and occasional additions to the PyGTK application list), but it is indeed in maintenance mode. Some ideas to improve the situation are: - Getting involved in improving the glib (gobject-introspection) and gtk+ win32 branches https://github.com/dieterv (Dieter's github repos with his patches to those modules) http://optionexplicit.be/**projects/gnome-windows/GTK+3/http://optionexplicit.be/projects/gnome-windows/GTK+3/(experimental builds and instructions on how to build them) https://bugzilla.gnome.org/**buglist.cgi?classification=** Platform;op_sys=Windows;query_**format=advanced;bug_status=** UNCONFIRMED;bug_status=NEW;**bug_status=ASSIGNED;bug_** status=REOPENED;bug_status=**NEEDINFO;version=3.0.x;** version=3.1.x;version=3.2.x;**version=3.3.x;version=3.4.x;** version=3.5.x;version=3.6.x;**version=3.7.x;product=gtk%2Bhttps://bugzilla.gnome.org/buglist.cgi?classification=Platform;op_sys=Windows;query_format=advanced;bug_status=UNCONFIRMED;bug_status=NEW;bug_status=ASSIGNED;bug_status=REOPENED;bug_status=NEEDINFO;version=3.0.x;version=3.1.x;version=3.2.x;version=3.3.x;version=3.4.x;version=3.5.x;version=3.6.x;version=3.7.x;product=gtk%2B(open bugs related to gtk+ 3 on win32) https://bugzilla.gnome.org/**buglist.cgi?classification=** Platform;op_sys=Windows;query_**format=advanced;bug_status=** UNCONFIRMED;bug_status=NEW;**bug_status=ASSIGNED;bug_** status=REOPENED;bug_status=**NEEDINFO;version=unspecified;** component=introspection;**product=glibhttps://bugzilla.gnome.org/buglist.cgi?classification=Platform;op_sys=Windows;query_format=advanced;bug_status=UNCONFIRMED;bug_status=NEW;bug_status=ASSIGNED;bug_status=REOPENED;bug_status=NEEDINFO;version=unspecified;component=introspection;product=glib(open bugs related to glib introspection) - Help the PyGObject documentation efforts.

[pygtk] create help for a multiplatform app
Hi to all, I'm developing a multiplatform app with python and gtk. It must work fine in linux and in window (maybe also OsX). As every good app It must have an help (better a contextual help) showing how to use it. But at this point I'm not sure what to do. I can see more than one option: 1) Using text capabilities of gtk (TextView, TextBuffer) I can create a doc browser that can display help, images and also simulate hyperlink. Pro -easy to implement -no other packages needed -work on all gtk platform Con -Doc must be stored plain text file (i.e. no html support) -No real print capabilities -Producing doc also requires some programming knoledge 2)I can create a pdf manual (have you any suggestion about tools I can use for this task?) Pro -Multiplatform -Print support -No programming knowledge Con -Need external app -Not sure how well AcrobatReader/evince/gpdf/(others?) can be manipulated from a pygtk-app: should I write specific code for every apps? 3)I can use an external widget like gtkhtml to create a simple browser for html pages (open a real browser like firefox for display a simple plain html page is a waste of resources IMHO) Pro -Doc in html Con -Need external package (not sure if these widget are also available for windows) and they must have also python bindings 4) Other ideas?

Re: [pygtk] gnomeprint questions
Hi to all, I'm replying to myself after a night spent on gnomeprint I've found some answers: -the basic method for print string with gnomeprint is to use the show() method of the GnomePrintContext object. First you have to set the cursor position using the move() method (the origin is on the bottom-left corner) and than you can show your string. if you want to know width and height of the string you can use the method get_width_utf8(the string) of object GnomePrintFont. For height info is more obscure; I'm using this but I don't know if there is a better solution: font_height = font.get_ascender() + font.get_descender() where font is a GnomePrintFont. -there is no easy way for print the contens of a TextBuffer according with tags. I've looked on some C sources of gtkSourceView project assuming that they know very well gnomeprint internals, (at least better than me :-) and the procedure they use is the following: basically for every chars in a line, you must look at its tags, take the one with highest priority and set the font according with the tag (i.e. weight foreground color, ). As said before you have to do this for every char. Once again I'm not sure this is the only solution (or the best solution) because I'm not an expert of gnomeprint. So if someone has more infos, please share with us! :-) I've attached an example and I hope that it can be useful to someone else; just a few words about it. It is inspired by the examples of Gustavo Carneiro (great work Gustavo!), you can grab it on gnome CVS. You start the example passing a file to print. Please note that the program save your print configuration on a file conf so you can have persistence of your settings over executions. If you make a selection into the TextView the gnomeprint Dialog will add the print selection option. You can enable/disable the line_number on output and you can change its step (change the self.print_line_number and self.line_number_step on __init__ method). If the line is too long, the program simply truncate it (and put a small arrow to indicate it). This is ok for my needs but probably not for your, so change it... I hope this can help!

Re: [pygtk] Py_Shell.py
Hi Yang,
I'm not sure to undestand well you question (feel free to correct me).
There are two possibilities: the former is use Py_Shell to load your
program, but this way can be really difficult especially if the program
you load is a gui (with gui I mean something that call the
gtk.main_loop) because the second call to main_loop will freeze the
Py_Shell interface; a lot of work should be done to avoid possible
deadlock etc., and this is a bit out of scope for Py_Shell.
The latter way is create your gui which embed Py_Shell and pass to the
shell a local dictionary. I'm going to explain last sentence (that's not
clear also to me :-))
Py_Shell is based on InteractiveConsole (IC) (InteractiveConsole and
InteractiveInterpreter are located into the code module, you can see the
python doc for more infos). When you create an IC object you can pass it
a dictionary; every command send to the IC will be executed into the
environment based on that dictionary so this is probably what you are
looking for .
So try somethings like this: in Py_Shell change the line where it's
created the InteractiveConsole (around line 287)
self.core=code.InteractiveConsole()
and replace with
self.core=code.InteractiveConsole(locals())
Hope this helps
Best regards!

Hello Pier,
That fixed my problem, thanks a lot for your program and help!
I know this is going to be a bit out of scope of the GUI, but I was
wondering if it's possible for this Py_Shell to be the original shell
that is used to load up the gui in the first place. Say I have this
Gui.py that loads up functions, variables, and the glade stuff. When I
run it, the gui pops out, with your Py_Shell embedded inside.
Currently, the Py_Shell inside the gui is a completely new one that has
no knowlege of the Gui.py functions/variables. Is there a way for
Py_Shell to have acess to them?
thanks again,

Re: [pygtk] Py_Shell.py
Hi to all!
Malcom has right, if you want to use the shell inside another
application, simply create this with:
gui = Shell_Gui(0)
you will have a frame instead of a window
I'm using Py_Shell inside a bigger app and this is the code I use for
create the shell and put into vpaned widget:
self.main_shell=Py_Shell.Shell_Gui(with_window=0)
glade_file.get_widget(vpaned1).add2(self.main_shell.gui)
Also two things to notice:
if you start the shell with with_window=0, you don't have the exit
button in the button's bar, and the quit method of the Shell_Gui class,
simply hide the frame (if you use with_window=1 this method call a
gtk.main_qiut())
I attached a new version of Py_Shell that fix a couple of problem:
- avoid duplicated entry into the autocompletetion list
- the width of the autocompletation popup is calculated with respect to
the length of the strings
This version requires pygtk 2.0 due to some function (pango.PIXELS)
not present in previous release (at least 1.99.16)
I'm sorry to post this into the list instead of giving you a link to a
page. I hope to have a web-page for my project (which includes Py_Shell)
in a week or two (I've register it on SF, so the only things that
remains is write the pages.. ). I will post the link ASAP
Best regards!

I have not tested what I am about to say -- I just had a quick read over
Pier's code...
It may not require all the trickiness of using a custom widget. The
Shell itself is just a frame widget (it you set with_window = 0). If you
construct the widget as s = Shell_Gui(0), s.gui will be the frame widget
that you can put into your widget hierarchy at the appropriate point.
So inside your larger application you will have some kind of
GtkContainer for holding the embedded shell. Just add the new frame
widget (s.gui) to this container and it should work. There are probably
a couple of details missing here, but I think the theory is correct. In
any case, look at the frame created in the Shell_Gui class and utilise
that directly.
Cheers,
Malcolm

Hi Jan!
thanks a lot for your feedback and you fix!
I've produced another diff against my Py_Shell.py which includes your
fix and somethings else; a small changelog:
-check for pygtk 2.0 (Jan)
-close/hide when Ctrl-D event is pressed (Jan)
enabling this only when Py_Shell is in it's own window
(I need it for my app but you can change it ...)
-scrolling back in history returns to an empty prompt
-press Home key into the last line, puts cursor to the start of the
logical line (I mean after )
-the same happens with Left key
- fix a bug with autocompletation (missing a = in separators)
Best regards!

Hi Pier,
nice work! Thanks a lot!
Just some comments:
1) I had to add an
'import pygtk
pygtk.require('2.0')'
to make it work.
2) If I scroll back in history using 'up' I am not able to get back to
the empty prompt afterwards.
3) Maybe the standalone version could react on 'CTRL-d' by exiting?
Attached is a little diff which solves 1) and 3).
I didn't try to dig deeper into 2) yet.

I attached a new version of Py_Shell that fix a couple of problem:
- avoid duplicated entry into the autocompletetion list
- the width of the autocompletation popup is calculated with respect
to
the length of the strings
This version requires pygtk 2.0 due to some function (pango.PIXELS)
not present in previous release (at least 1.99.16)
I'm sorry to post this into the list instead of giving you a link to a
page. I hope to have a web-page for my project (which includes
Py_Shell)
in a week or two (I've register it on SF, so the only things that
remains is write the pages.. ). I will post the link ASAP

Hi Yang!

xml.get_widget(vpaned1).add2(main_shell.gui)
I've looked to my code, I think the solution is that you miss a
main_shell.gui.show_all()
In my code I call it with the empty frame, that's why you see only the
frame.
You ca fix it:
put line 313 frame.show_all() after line 314 frame.add(box)

Traceback (most recent call last):

It seems that somethings is wrong with your configuration; are you sure
you have installed pygtk into the right location? The script doesn't
find the required version of pygtk
Hope this help!

Re: [pygtk] put small images into a TextView border window
Hi to all! I reply to myself, because I've found the solution of my question. To better undestand what I mean with small images into a gtk.TextView border window you can have a look to the screenshot I attached. So, step one obtain a reference to the border window you want to use left_win= view.get_window(gtk.TEXT_WINDOW_LEFT) #view is an instance #of gtk.TextView than create a color to use as background color for your image; to obtain a color you can do the follow: colormap=left_win.get_colormap() color=colormap.alloc_color(seashell) (seashell is the border color of the screenshot) At this point you can create a pixmap from file. I use the function gtk.gdk.pixmap_create_from_xpm: (pixmap, mask)= gtk.gdk.pixmap_create_from_xpm(left_win, color, file_name ) Obtain image width and height (width, height)= pixmap.get_size() Finally you can put the pixmap into the border window with draw_drawable method left_win.draw_drawable(gc, pixmap, src_x, src_y, des_x , des_y, width, height) gc is the graphics context obtained with a call like this gc = left_win.new_gc() I hope this can be useful to someone else..

[pygtk] control pasted text
Hi to all! I'm developing an editor based on gtkTextView and gtkTextBuffer. I'm looking for the possibility to perform some actions with pasted text. More precisely if a user paste some text into the editor, I must be able to control if there are not permitted chars (for example tabs) or at least to know the length of pasted text. For the second problem (to know the length of pasted text)the only solution I've found is to get the char_count before and after paste_clipboard is emitted, so the difference of the two values is the length of pasted text, but I'm not sure that this is the correct solution. Has anyone some tips about this? Where should I look for clipboard informations? Thank you!

Re: [pygtk] Get characters in a TextView
Hi, for have an iter at the current cursor position you can do: iter=buffer.get_iter_at_mark(buffer.get_insert()) at this point you use iter.get_char() for obtain the current char, then move the iter with iter.backward_char() and again iter.get_char() for check the previous char Best Regards!

[pygtk] gtk.TextIter
Hi to all, I'm learning the new gtk2 and in particular the multiline text widgets (TextBuffer TextView Co.) My idea is to see if I can use theese widgets in my app. The app is basically and editor for Python and since now I've used the Scintilla widget that's very cool! So first question: Is it possible to create a class based on new widgets of gtk2,that implements a widget with syntax styling, folding and everythings else like Scintilla? I suppose that the answer is Yes, but how much difficult will it be (in particular the auto-highlight of text and the folding rutine)? And now about TextIter: can you explain me in a few words what is a TextIter and how to create one (probably an example will be the perfect explanation) [An off topic question: does anybody know when we can have a glade2 program to play with?] Thank you very much! ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk
