Re: [Sugar-devel] help about the get_preview function of activity.Activity class to take screenshots
Hi Sumit,
I just fixed the example code in the pyabiword module of abiword to
give an example
of how this works.
The important line in this example is:
i.props.pixbuf = abi.render_page_to_image(1)
The converts page number 1 to a GdkPixbuf. Once you have a GdkPixbuf,
in this case in
a Gtk.Image you can convert it to whatever format you wish.
From the PyGtk reference manual http://www.pygtk.org/docs/pygtk/
you convert this to an image with:
http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--save
So if you wanted the GdkPixbuf directly you would do:
PagePixbuf = abi.render_page_to_image(1)
PagePixbuf.save(filename,png)
Where filename is the name of the file you wish to store to.
Cheers!
Martin
PS. here is test.py which shows the feature in action (thanks for the
patch tomeu!)

Hi everyone,
Can anyone please guide me about the proper use of the get_preview function
of the activity.Activity class of sugar. I had a look at its api, it seems
to be returning a dictionary sort of thing which is called as the png image.
What I want to do is to save this image somewhere in the datastore and show
this image later to the user in my activity. So, what I want to ask is to
how to load this information in the form of an image later on
programatically. Can we load it using the gtk.image widget and what is the
right procedure to save this information.

Re: [Sugar-devel] creating your own templates in write activity
Hi Manusheel, There is no specific pyabiword binding for insert textbox but your can use the following technique to access the abiword/src/wp/ap/xp/ap_EditMethods.cpp function that provide the interface to libabiword. do: self._abiword_canvas.invoke_cmd(insTextbox,,0,0) To invoke the GUI to insert a textbox.

We have been working on developing a template builder tool in write activity, and wish to have your pointers on certain features- 1.

We looked at abiwidget.h file closely, and it seems to us that there is no method (function) provided to add textboxes. We investigated deeper into the details, and arrived at an approach to develop the text box feature- a. Create a textbox class on the lines of tablecreator class- It seems that we need to work on 4 files: 1. OXML_Element_TextBox.cpp 2. OXML_Element_TextBox.h 3. OXMLi_ListenerState_TextBox.cpp 4. OXMLi_ListenerState_TextBox.h b. Use invoke_cmd method to insert Textbox. We are not very clear on what all arguments can be passed in this method, and their usage. Could you please direct us to a resource, which could be helpful in understanding this.

In the meantime one can fudge this very simply by having each user agree to use their own color for writing text. ie Joe chooses red, Alice choose green, Sarah chooses blue etc. When everyone is happy with the final document choose select-all and change all colours to black. This will work immediately. BTW people might interested in our new service: http://abicollab.net As an easy way to share and collaborate on document creation in a scalable world-wide fashion. With this you can easily setup group documents and work on them in real-time (just like Write does). AbiWord-2.6.4 has the code to connect to this but it is not enabled by default as we're still working on some final bug fixes.

Re: [sugar] Programming environments on the XO
Hi Samuel, Marc Maurer has done 95% of the work required to do multi-programming language syntax highlighting in libabiword. The advantage of using libabiword is that you get collaboration for free. It is easy enough to embed this in your own canvas and hook up the controls you need or want, just as we've done for Write. Marc is a bit of a perfectionist so I'm not sure how usable 95% of the work is and whether it could be finished by simply using it and providing bug reports as needed would be. Hopefully, Marc will chime in soon. Cheers Martin On Thu, 2008-07-17 at 00:39 -0400, Samuel Klein wrote: There has been talk about expanding Pippy to support a variety of programming languages, perhaps as plugins; to add syntax highlighting; and general interest in seeing Develop proceed. Syntax highlighting in Write has been brought up as well. C and Javascript environments have been specifically highlighted, since C is used for a fair bit of code that we ship; but enthusiasts of Ruby and many other languages have considered providing an intro dev environment as a standalone activity, one per language. And HTML creation is possible in Write but without highlighting, and it is not obvious how to put this to good use. Finally, we now have activities for Etoys (Squeak), Scratch, and Turtle Art, but not yet a Logo activity; though a few people are working on the latter. Where are we with these developments? What plans are there to complete any of the above this year? What specific features should we schedule to support the above, and which is most important?

Re: [Production] Amharic input
Hi Kim, Judging by the fact that AbiWord (Write) won't let you enter English characters, I suspect that the Gtk IM is permently triggered. I would guess that somehow we need to overide the locale seen by environment for the English characters to be entered. With regards to Write, I don't believe that setting the locale accessible from UI as it currently stands. However if you manage to set the locale to en_US and start a new Write session it will likely accept English. Cheers Martin 2008/5/1 Kim Quirk [EMAIL PROTECTED]: Using Build 703 + G1G1 activities; the terminal acitivity, pippy, and abiword were all tested and I can't figure out how to get English characters.

I set the mfg-data just as Quanta is setting it, based on the values from the mfg-data table: KMKLKVLOSKU(s)KA Reference olpcus,etolpc2,basicam_ET.UTF-811us Then do the cleaninstall (Arjun - did you do a cleaninstall after you set the values for keyboard??). Can't get US/English characters in Pippy, Terminal, AbiWord activities. But I did get English numbers (top row).
