I just started a new small python project on google code which goal is to easily create clickable graphs on a GKT+ goocanvas. The initial idea comes from this code snippet http://www.daniweb.com/software-development/python/code/323792 . I want to do about the same, but instead of simply drawing the graph, I want to display it on a goocanvas to make it interactive.
The project's page is here http://code.google.com/p/clickonpy/ , there is no code yet, but if some members of the python forum are ready to contribute, please let me know :)
Clickonpy produced its first clickable graphs. To do so, it only needs a sequence of pairs of "connected" arbitrary python objects, and a function to call when one of the objects is clicked. Here is an example code
from clickonpy.app import App
if __name__ == "__main__":
def on_click(graph, obj, button):
# this will be called when the user clicks on a graph node
print "{0} was clicked with button {1}".format(repr(obj), button)
def pairs():
# example graph: take a series of words and connect those with at least 3 common letters
words = "format frame framework function game generator grid gui help".split()
for i, w0 in enumerate(words):
for w1 in words[i+1:]:
if sum(x in w1 for x in set(w0)) >= 3:
yield w0, w1
app = App()
app.create_graph(pairs(), node_click = on_click)
for obj in app.graph:
app.graph[obj].label = str(obj).capitalize()
app.show_graph()
app.main()
""" my output --->
'framework' was clicked with button 1
'framework' was clicked with button 2
'generator' was clicked with button 3
'function' was clicked with button 2
'frame' was clicked with button 1
'format' was clicked with button 1
'game' was clicked with button 3
'game' was clicked with button 2
'game' was clicked with button 3
'generator' was clicked with button 1
"""
This code displays a gtk window containing the graph, as shown in the attached screenshot.
The code was run in linux, it needs pygtk, pycairo, pygoocanvas, pygraphviz and pydot. I currently don't know if it will work in windows. The key point is to install pygoocanvas in windows.
You can currently download clickonpy by pulling its mercurial repository. I would appreciate ifsomeone helps me with setuptools to write an installer ?
