  • How to create a glib.Source from Python?

    - by Matt Joiner
    I want to integrate some asyncore.dispatcher instances into GLib's default main context. I figure I can create a custom GSource that's able to detect event readiness on the various sockets in asyncore.socket_map. From C I believe this is done by creating the necessary GSourceFuncs which could involve cheap and non-blocking calls to select, and then handling them using asyncore.read, .write and friends. How do I actually create a GSource from Python? The class glib.Source is undocumented, and attempts to use the class interactively have been in vain. Is there some other method that allows me to handled socket events in the asyncore module without resorting to timeouts (or anything that endangers potential throughput and CPU usage)?

  • Gtk: How can I get a part of a file in a textview with scrollbars relating to the full file

    - by badgerman1
    I'm trying to make a very large file editor (where the editor only stores a part of the buffer in memory at a time), but I'm stuck while building my textview object. Basically- I know that I have to be able to update the text view buffer dynamically, and I don't know hot to get the scrollbars to relate to the full file while the textview contains only a small buffer of the file. I've played with Gtk.Adjustment on a Gtk.ScrolledWindow and ScrollBars, but though I can extend the range of the scrollbars, they still apply to the range of the buffer and not the filesize (which I try to set via Gtk.Adjustment parameters) when I load into textview. I need to have a widget that "knows" that it is looking at a part of a file, and can load/unload buffers as necessary to view different parts of the file. So far, I believe I'll respond to the "change_view" to calculate when I'm off, or about to be off the current buffer and need to load the next, but I don't know how to get the scrollbars to have the top relate to the beginning of the file, and the bottom relate to the end of the file, rather than to the loaded buffer in textview. Any help would be greatly appreciated, thanks!

  • how to render custom columns with a GenericTreeModel

    - by Giorgio Gelardi
    I have to display some data in a treeview. The "real" data model is huge and I cannot copy all the stuff in a TreeStore, so I guess I should use a GenericTreeModel to act like a virtual treeview. Btw the first column is the classic icon+text style and I think I should declare a column with a CellRendererPixbuf (faq sample), but I'm not sure what the model methods on_get_n_columns() and on_get_value() should return. It's both a Pixbuf and a string value for the same column. Any help will be appreciated.

  • After installing Meld on 32-bit Karmic on 64-bit machine: "Meld requires pygtk 2.8.0 or higher."

    - by Lynx
    I got this error after installing Meld on a new Karmic installation: ~$ meld No module named pygtk Meld requires pygtk 2.8.0 or higher. I installed the latest version of python-gtk with aptitude but I'm not sure what version is actually installed. My python version is 2.6. This is weird because I have another machine that runs Karmic and Meld without a problem. The only difference between the two machines is the one with the error is a 64-bit machine running a 32-bit installation of Karmic. Could that be the problem?

  • Learning frameworks without learning languages

    - by Tom Morris
    I've been reading up on GUI frameworks including WPF, GTK and Cocoa (UIKit). I don't really do anything related to Windows (I'm a Mac and Linux guy) or .NET, but I'd like to be able to throw together GUIs for various operating systems. We are in the enviable position now of having high level scripting languages that work with all of the major GUI toolkits. If you are doing Linux GUI programming, you could use GTK in C, but why not just use PyGTK (or PyQt). Similarly, for Java, one can use JRuby. For Mac, there's MacRuby. And on .NET, there's IronRuby. This is all fine and good, and if you are building a serious project, there are tradeoffs that you might encounter when deciding whether to, say, build a WPF app in C# or in IronRuby, or whether you are going to use PyGTK or not. The subjective question I have is: what about learning those frameworks? Are there strong reasons why one should or should not learn something like WPF or Cocoa in a language one is familiar with rather than having to learn a new language as well? I'm not saying you should never learn the language. If you are building Windows applications and you don't know C#, that might be a bit of a problem. But do you think it is okay to learn the framework first? This is both a general question and a specific question. I've used some Cocoa classes from Ruby and Python using things like PyObjC and there always seems to be an impedance mismatch because of the way Objective C libraries get built. Experiences and strong opinions welcome!

  • Open Dialog, created with quickly does not work

    - by Marian Lux
    I tried to open a dialog like David Planella describs here (and quickly help add): Open Custom Dialog Windows (PyGTK + Quickly) But this don't works for me. I always get the same Error-Message if I open the creadted Dialog: AttributeError: 'module' object has no attribute 'NewDialogNameDialog' (Note: My Dialog-Name is replaced with "NewDialogNameDialog" to be more general.) I tried to test a tutorial for the Ubuntu app showdown to learn how to use quickly and python. I can also add the whole source-code if you wish.

  • How to control gnome-terminal from Python scrypt?

    - by user936401
    I am developing an application in PyGtk, and would like to launch a gnome-terminal and output commands to it. My user should then be able to modify the command, or maybe ignore using the up arrow ... etc. I have been able to launch a terminal, but can't work out how to send commands. This is how my application starts: class App(Gtk.Window): def __init__(self): Gtk.Window.__init__(self) process=subprocess.Popen(["gnome-terminal", "--class=App", "--name=app"], shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) response,error=process.communicate()

    I've done some spin buttons with Glade for my Python/GTK3 app, but I don't know how to set things like default, lower or higher value. How can I do it? Using the following things for development: Python 2.7.3 GTK 3 Glade 3.12.1 1) I need to change things from script, as I need to set default value and maximum value as a variable; 2) I saw the PyGTK documentation before, it's not working for GTK3; 3) please don't direct me to the GTK3 docummentation... I can't understand it :P

  • Error accessing Gio.Gsettings on application made in quickly

    - by Zane Swafford
    I am trying to develop an application using the quickly/pygtk stack. I got my Gsettings schemas all set up in ~/app-name-here/data/glib-2.0/schemas/net.launchpad.app-name-here.gschema.xml correctly and I am able to access it just fine in my preferences dialog window that is located in ~/app-name-here/app-name-here/PreferencesDialog.py via from gi.repository import Gtk, Gio settings = Gio.Settings("net.launchpad.app-name-here") settings.get_boolean('notify') settings.set_boolean('notify', True) but when I try to check the value of one of my settings in a file located in ~/app-name-here/bin/Daemon.py that I use as a script to run in the background and send notifications by a similar method of from gi.repository import Gio settings = Gio.Settings("net.launchpad.app-name-here") settings.get_boolean('notify') it fails at the line that says settings = Gio.Settings("net.launchpad.app-name-here") and spits out a nasty error (Daemon.py:26100): GLib-GIO-ERROR **: Settings schema 'net.launchpad.app-name-here' is not installed Despite the fact that I can open up dconf-editor and find the settings under net/launchpad/app-name-here. Any thoughts?

  • Quickly and Python Twisted

    - by Aaron
    I am creating a Quickly application that makes use of Python Twisted. When the user launches a window, I want to start the Twisted server I wrote. However, when I do this, it freezes the GUI, because the reactor.run method is constantly running after it is started. I need a way to start the Twisted reactor in its own thread, so that the GUI will continue to operate while the reactor is running. I have read about using Twisted with pyGTK in the Twisted documentation, but I am not sure how I would accomplish this with a Quickly application. What is the best way to start my Twisted server when a window opens without freezing the GUI? Update: My if __name__ == '__main__' statement at the end of my dialog file is: print 'Preparing GLib' GLib.idle_add(before_running) print 'Staring Reactor' from twisted.internet import reactor reactor.run()` I have imported and installed twisted.gtk3reactor earlier on in the file. The before_running method contains dialog = ClientDialog() and dialog.show, as well as the rest of the code I want to run when the dialog opens.

  • How do I show an animated gif in the app I am developing?

    - by Agmenor
    I am developing Discvur, a simple Imgur viewer, for the Ubuntu App Showdown. Therefore I use quickly + Glade + Gtk + Python. PyGObject instead of PyGtk would be highly appreciated. I would like to display some animated gifs in my program. What I tried was inserting a viewport, then an image, and then in the 'Edit Image' field I selected a gif animation (in my case "../media/akO1i.gif"). When I run my app, the gif is displayed but it is not moving (I only see the first frame). Is it possible to show animated gifs in my app? What is the best and/or easiest way to do it: use the image widget, or a WebKit field, or something else?

  • How to balance programming projects between feasibility and usefulness

    - by tyjkenn
    I've become fairly competent as a programmer, but I would not say I am a master. I work independently, most as a hobby, although I have done some freelance PHP work. I tend to find myself dabbling in a lot of things: Java Android SDK, Arduino, game scripting, Lua, etc. I've reached the point where I want to start a real software project, but cannot think of a small enough project that allows me enough practice, while still being able to publish a decent piece of software in a reasonable amount of time, and build up a portfolio. More specifically, I was looking at Ubuntu development, in Python, using the Quickly toolset, which includes the PyGTK libraries. So the question is, what is the best way to come up with a small project that is still useful, as a starting point to a software development career?

  • GTK detecting window resize from the user

    In GTK (or pygtk or gtkmm...) How can I detect that an application window has been manually resized by the user, as is typically done by dragging the window's edge? I need to find a way to differentiate manual resizes from resizes that originate from gtk, such as changes in window content.

When I try to access these files I have the error that the resource is unavailable (the path that I'm trying to open is something like file.zip/gui/gui.ui ). How can I handle this situation?

  • How to embed a Python interpreter in a PyQT widget

    I want to be able to bring up an interactive python terminal from my python application. Some, but not all, variables in my program needs to be exposed to the interpreter. Currently I use a sub-classed and modified QPlainTextEdit and route all "commands" there to eval or exec, and keep track of a separate namespace in a dict. However there got to be a more elegant and robust way! How? Here is an example doing just what I want, but it is with IPython and pyGTK... http://ipython.scipy.org/moin/Cookbook/EmbeddingInGTK
