pygtk

I have to save various properties of custom GTK elements to a file for future use and decided to use JSON because of the simple format and nesting of dicts. Many properties are GTK enums, like gtk.PAGE_ORIENTATION_PORTRAIT , gtk.ANCHOR_CENTER and pango.ALIGN_LEFT . They have a unique name which can be retrieved with obj.value_name to get a valid JSON type. Currently I have 2 methods for each of my elements: to_str() to get the value_name and from_str() which maps the str to the enum again. I would like to automate this so I don't forget to call these and clean up the code a bit. The

I have completed a program using Python and Opencv2. Now, I wants to add a GUI Window to my program. I am having some experience with PyGtk3. So, I modified my code to adopt with PyGtk3. But, I got errors. So, I tried a simple program to find out the actual mistake. My testing code is, import pygtk pygtk.require('2.0') import gtk import numpy as np import cv2 builder = gtk.Builder() builder.add_from_file("GUI.glade") window = builder.get_object("window1") window.set_title("Single Object Tracking") window.connect("delete-event", gtk.main_quit) window.show_all() img = cv2.imread('Birds.jpg') cv2

I have a two-thread application: GUI, and some background work. I'm trying to send requests to the main thread to do GUI updates (move a progress bar), but it doesn't seem to work. I've boiled it down to a really minimal example: import pygtk pygtk.require('2.0') import glib import gtk import threading import sys import time def idle(): sys.stderr.write('Hello from another world.\n') sys.stderr.flush() gtk.main_quit() def another_thread(): time.sleep(1) glib.idle_add(idle) thread = threading.Thread(target=another_thread) thread.start() gtk.main() This should, I thought, print something to

Experimenting with a battery monitor icon at the moment in Python using pygtk and egg.trayicon to create an icon to display a battery icon/tooltip. I seem to be able to add the icon and the tooltip text, but when it then reaches the gtk.main() stage I need a way to modify these so it can then show the updated values. I've tried gobject.idle_add() and gobject.timeout_add() without much luck, not sure where to go from this. Anyone got any ideas? EDIT : Perhaps not the clearest of questions. I need to loop, fetching information from acpi while running and apply it to widgets inside the gtk

On a happy (if not irrevelent) note, this is the absolute last obstacle in this particular project. If I fix this, I have my first significant dot release (1.0), and the project will be going public. Thanks to everyone here on SO for helping me through this project, and my other two (the answers help across the board, as they should). Now, to the actual question... I have a toolbar in my application (Python 2.7, PyGTK) which has a number of gtk.ToolButton objects on it. These function just fine. I have working "clicked" events tied to them. However, I need to also connect them to "enter-notify

I have a problem with threads in pygtk. My application consist of a program that downloads pictures off the internet and then displays it with pygtk. The problem is that in order to do this and keep the GUI responsive, I need to use threads. So I got into a callback after the user clicked on the button "Download pictures" and I call the method to download the pictures that is within that same class. thread.start_new_thread(self.images_download, (path,pages) This won't work. The only way I get my program to get into the thread is by using gtk.threads_init() Before starting any thread. Now it
