Writing python bindings, getting pygobject_new_full assertion failed error. Need assistance.

2009-12-11T07:57:13Z

I'm working on writing python bindings for the Thunar extension framework (the code is based on the nautilus python bindings) and I'm pretty close, but I can't figure out how to get past this error that happens when I try to convert a GObject variable to a PyObject variable.

The call that is causing the trouble is pygobject_new() and I get the following error:

TypeError: multiple bases have instance lay-out conflict
**
ERROR:/build/buildd/pygobject-2.18.0/gobject/pygobject.c:924:pygobject_new_full: assertion failed: (tp != NULL)
Aborted

The code in question is here: http://github.com/adamplumb/thunarx-python/blob/master/src/thunarx-python-object.c line 147.

My project is up at http://github.com/adamplumb/thunarx-python and it compiles and installs, it just needs thunar master from http://git.xfce.org/xfce/thunar/ to run. To reproduce the issue, load up thunar with the bindings loaded and a python extension (available in the examples folder) loaded and right click on a folder or file.

I feel like there is a tiny thing I'm doing wrong here and would appreciate it if some folks could look over my code and see if they can see any glaring causes for this.

Thanks,
Adam

Is it possible to make parent items in ComboCoxEntry drop-down list selectable

2009-12-11T05:48:28Z

I'm adding ComboBoxEntry and a TreeStore as a model to a window.
TreeStore contains only simple hierarchy of strings.
Example:
str1
str2 --> str3
str2 --> str4

My question is: Is it possible to make parent items in drop-down list
selectable (str2 in example)?

Unicode Problem using TextBuffer()

2009-12-11T03:34:23Z

Hi all,
I got a problem using the method insert_at_cursor applied at the
TextBuffer object.
the Worning is :
GtkWarning: gtk_text_buffer_emit_insert:
assertion `g_utf8_validate (text, len, NULL)' failed
_tb.insert_at_cursor(_s)

I read the data from a file *.dxf and i try to populate the TextBuffer....

I
know that it's not a problem of the text buffer (He want unicode char ...)..
but may be someone have olready meet this problem.

Googoling .. i found a lot
of article and they suggest to use function like the following to conver the
string .. but i get always the some error ..

def to_unicode(obj, encoding='utf-
8'):
"""
Transform a string in a different format Default utf-8

"""
if isinstance(obj, basestring):
if not isinstance(obj,
unicode):
obj = unicode(obj, encoding)
return obj
else:

raise TypeError, "Invalid object type : " + `type(obj)`

Thanks
Matteo

treeview: next visible (not collpsed) row?

2009-12-10T05:26:06Z

Hi,

i'm loosing too much time to find out a pretty simple thing so maybe some
has already a working solution.

I want to know -given a path- which is the next visible (i.e. not hidden
by the parend being collapsed) path. The same algorithm used by threeview
when -after selecting a row- you press Down and traverse the treeview.

import gtk
Window = gtk.Window(gtk.WINDOW_TOPLEVEL)
Button=gtk.Button("Hello")

hb = gtk.HBox()
vb = gtk.VBox()
hb.pack_start(vb, False, False)

vb.pack_start(Button, False, False)

Window.add(hb)

Button.set_border_width(0)
Button.set_size_request(100,400)
Window.set_default_size(200,600)
Window.show_all()
gtk.main()

HBox considers expand and fill pack parameters horizontally, and VBox
considers them vertically. So depending on your GUI you sometimes need
both.

But a simple button in a window is not the best way to learn how Gtk+
GUI packing works, it is not a real world case and will just continue to
confuse you.

I suggest using glade-3 to design some different GUIs, and experimenting
with the effect of expand and fill when packing widgets.

In general you should not set minimum/default size (this is not windows
forms). It is best to accomplish the GUI layout you want using the
correct application of packing rules, and correct uses of alignments and
sizegroups.

Hi John

when I test your code ,I find that the button's height is ok,400px,but the width is fill

when I change vb = gtk.VBox() to vb = gtk.HBox()

run your code ,then the width is 100px, ok,but the height is fill

is it true I need to use gtk's another object but not HBox and VBox?

which object is ok?

Thank you

You said it yourself, it sets the minimum size. The widget can grow, and
it does when it is packed into the window.

If you do not want the widget to expand into all available space, then
pack it into a container with the appropriate values for fill and expand
set (False)

PyGTK Button Size Question

2009-12-09T06:50:37Z

Hi everyone

I know the method:

gtk.Widget.set_size_request

    def set_size_request(width, height)

`width` :	the width the widget should request, or -1 to unset
`height` :	the height the widget should request, or -1 to unset

The set_size_request() method sets the minimum size of a widget to the values specified by width and height. You can use this method to force a widget to be either larger or smaller than it normally would be. In most cases, the gtk.Window.set_default_size() is a better choice for toplevel windows than this method. Setting the default size will still allow users to shrink the window but setting the size request will force them to leave the window at least as large as the size request. When dealing with window sizes, the gtk.Window.set_geometry_hints() can be a useful method as well.

Note

There is an inherent danger when setting any fixed size - themes, translations into other languages, different fonts, and user action can all change the appropriate size for a given widget. So, it's basically impossible to hard code a size that will always be correct.

The size request of a widget is the smallest size a widget can accept while still functioning well and drawing itself correctly. However in some strange cases a widget may be allocated less than its requested size, and in many cases a widget may be allocated more space than it requested. If the size request in a given direction is -1 (unset), then the "natural" size request of the widget will be used instead. Widgets can't actually be allocated a size less than 1 by 1, but you can pass 0,0 to this method to mean "as small as possible".

but when I test the method by using the follow code

def __init__(self):

# Create a new window

self.Window = gtk.Window(gtk.WINDOW_TOPLEVEL)

self.Button=gtk.Button("Hello")

self.Window.add(self.Button)

self.Button.set_border_width(0)

self.Button.set_size_request(100,400)

self.Window.set_default_size(200,600)

self.Button.show()

self.Window.show()

the default window's width is 200,and height is 600,but the button fill the window,do I make something wrong?

Re: about "clicked" signal

2009-12-09T05:15:04Z

maybe I have known the reason

The function specified in the second argument is called a "callback function", and should generally be of the form:

  def callback_func(widget, callback_data):

where the first argument will be a pointer to the widget that emitted the signal, and the second (callback_data) a pointer to the data given as the last argument to the connect() method as shown above.

If the callback function is an object method then it will have the general form:

  def callback_meth(self, widget, callback_data):

where self is the object instance invoking the method.

Hi everyone
   when I study pygtk, for the code
   self.button1.connect("clicked", self.callback, "button 1")

   when I check the PyGTK 2.0 Reference Manual,I find this:

     The "clicked" gtk.Button Signal
def callback(button, user_param1, ...)

button :
the button that received the signal
user_param1 :
the first user parameter (if any) specified with the connect() method

... :
additional user parameters (if any)
   there are only two Parameters

   so I change the default callback function


     def callback(self,widget, data=None):
   print "Hello again - %s was pressed" % data

   to

        def callback(widget, data=None):
   print "Hello again - %s was pressed" % data

   but I get this error

     TypeError: callback() takes at most 2 arguments (3 given)



   can any one help me ?

installing bonobo server file for a new applet

2009-12-08T11:59:04Z

Hi All,

I am relatively a beginner in python and quite newbie to pygtk.
I made a software for one of my national weather service (Hungary).
It consist of 3 application, a command line version, a gnome application
and a gnome applet.
All works well (or I hope so ;) ) and I am in phase to create a tarball with
autoconf and later I plan to create a deb package (I am using ubuntu).

My problem comes from here. I am an absolute beginner to autoconf :P
but I am sure I will learn it. Unfortunatelly I did not find any info about
how to make bonobo activation server to restart itself to notice the new
*.server file and make the applet available in the gnome panel "Add" window.
If I log out and back it is ok, but as I realized this is not required when I
install a gnome applet with the package manager so it should be another
way...

What is the normal way to achieve the above?

How Accelerators Work

2009-12-07T15:03:26Z

Hi All,

I've been looking around a bit but haven't really found anything that
answers my questions. If someone knows of some documentation that helps
me and can point me towards it, I'd be happy with that.

I'm trying to write an application that has a customizable menu system
with plugins. I wanted to use the UIManager to make it easier to store
and load the configuration.

I was hoping to be able to use gtk.Action objects to encapsulate all the
aspects of an action, accelerator included. That way a plugin just needs
to create the actions and the rest of system can plug them into the
widgets. But all I can find on the actions are to set the accelerator
paths.

>From what I can tell, accelerators can only be applied to actual
widgets. Am I between a rock and hard place on this or am I not seeing
something?

Something else that I was hoping I could clear up was, what are
accelerator paths exactly? Are they directly related to the menu path?
Or are they freeform, kind of like groups so that the application can
group accelerators together? If so isn't that what AccelGroups are for?
Or is this to do with the fact that GTK is written in C?

Any help with accelerators in general would be greatly appreciated.

Thanks

Kevin

PyGTK and visual python integration

2009-12-07T10:15:10Z

Hello PyGTK list,

I'm trying to use Visual Python [1] with PyGTK.

My goal is to run the PyGTK app from an ipython console with the interactive loop, to launch the visual python and to be able to process the input coming from the console.

I was able to do it on ubuntu jaunty, but for some reasons this is not the case anymore in karmic.

The version I was using before of Ipython 0.9.1, what is shipped with karmic is 0.10.
The PyGTK in jaunty is 2.14.1-1ubuntu1 and in karmic is 2.16.0-0ubuntu1

With the 0.9.1 ipython version and the 2.14 PyGTK I was able to achieve this behaviour starting the console with the -pylab options, and I was using GTKAgg as my backend.

In my program it was possible to start a visual window clicking on a gtk button. I attach a simple case code to show the problem.

What has changed ?

Is Ipython, PyGTK or both?

[1] http://vpython.org/
[2] http://ipython.scipy.org

Regards,
Michele.

Sure. For instance, you can install python-gtk2-doc in Debian or Ubuntu,
or just find it in the original pygtk tarball from the official site.

(html format)

You can sell your app for money. What you must do if you use LGPL'd
libraries is to dynamically line to those libraries and provide a way
for users to obtain source to the LGPL'd libraries. I'm simplifying
here; I suggest you read the license and look at some of the many
explanations on the web, including http://www.gnu.org/copyleft/lesser.html

You do not need to buy a license to Wing IDE Professional to obtain the
source to the LGPL'd libraries shipped with Wing.

I should add that I am not a lawyer so this is not legal advice.

Cheers,

John

Hi,

Pygtk and the gtk+ stack are LGPL so you must dynamically link and
provide a way to obtain the source. Wing IDE does this.

John

2009-12-06T12:16:03Z

hi all,
i know that is many software licenses.
coz my english is not good i dont know how to use.

Question is:
May i sell application (written using python,
pygtk and pygtksourceview2) to my employer or somebody without source
code. just executable (using cx_freeze) or in compiled bytecode ?

with python and pygtk no prob i think [ WingIDE ]
but with PyGtkSourceView2 which is LGPL i think.

thanks for answers.

Visible area of a Widget

2009-12-06T10:57:25Z

Hey,

how can I retrieve the visible area of a widget which lays
within a Viewport in a ScrolledWindow?

Propably a sketch tells it better:

.(0,0) _ _ _ _ _ _ _ _ _ _ _ _ _ _ _.(200,0)
| |^|
|
| | |
|
| | |
.(0,20)_______________________________|
| |x|
| |x|
| a = visible_area.get_allocation() |x|
| |x|
| a.x => 0 , a,y => 20 |x|
| a.width => 200 , a.height => 80 |x|
| |x|
| |x|
|___________________________________.(200,100)
|
| | |
|
|_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _|↓|

So, the values within the drawn area are interesting to me,
but I don't know how to get them.

I'd appreciate any help.

Thanks

Henning

Re: Printing pedigree chart/family tree

2009-12-05T08:02:51Z

Hy,

You could try to use pyblassreports on http://pyblassreports.sourceforge.net/, it's something like Crystal Reports.

Subject: [pygtk] Printing pedigree chart/family tree

Hello,

In my application, the user can set up a pedigree and then print it out.
I do this with cairo, draw lines and boxes with text in it.
Now I'd like to extend this, so the user can choose what information there should be in the boxes, how many generations, etc.. I can hardcode some templates and use them (like I do now with 1), but it is alot of work.

So, is there an easy way to generate pedigree charts/family trees, and then print them out with PyGTK? I read about reportlab, will this satisfy my needs?

Cheers,
Timo
