POHow to import function handlers from other file to a Python/GTK Builder program?
text
Body
copied!<p>I have a Python script which uses a glade file to define its UI, and has a lot of repetitive widgets, each one to adjust a different numerical attribute of a certain active object. Since it is repetitive, I decided to define all the handlers in a separate file for encapsulation and readability. Here are some code excerpts:</p> <p>The main file:</p> <pre><code>import pygtk pygtk.require('2.0') import gtk, gobject, cairo, gtk.glade from Handlers import Handlers from FramesetParameters import FramesetParameters from GeometricRules import GeometricRules from BikeDrawing import BikeDrawing p=FramesetParameters("fitting", "handling", "construction") builder = gtk.Builder() builder.add_from_file("FramesetDesignerUI.glade") Handlers(p) builder.connect_signals(Handlers.__dict__) mainWindow = builder.get_object("mainWindow") mainWindow.show_all() gtk.main() </code></pre> <p>The Handlers.py file:</p> <pre><code>class Handlers: def adjustbottomBracketHeight(widget): obj.bottomBracketHeight = widget.get_value() def adjustseatTubeAngle(widget): obj.seatTubeAngle = widget.get_value() def adjustseatTubeLength(widget): obj.seatTubeLength = widget.get_value() def adjusttopTubeLength(widget): obj.topTubeLength = widget.get_value() def adjustheadTubeAngle(widget): obj.headTubeAngle = widget.get_value() def adjustheadTubeTopHeight(widget): obj.headTubeTopHeight = widget.get_value() def adjustrearAxlePosition(widget): obj.rearAxlePosition = widget.get_value() def adjusttrail(widget): obj.trail = widget.get_value() def adjustseatTubeExtension(widget): obj.seatTubeExtension = widget.get_value() def adjustheadTubeUpperExtension(widget): obj.headTubeUpperExtension = widget.get_value() def adjustheadTubeLowerExtension(widget): obj.headTubeLowerExtension = widget.get_value() def adjustforkCrownBulk(widget): obj.forkCrownBulk = widget.get_value() </code></pre> <p>When I run the program, the GUI shows up properly, but when I move a slider I get this error:</p> <pre><code>Traceback (most recent call last): File "/home/helton/Dropbox/Profilez/00Computacional/00REFACTORY97/Handlers.py", line 6, in adjustseatTubeAngle obj.seatTubeAngle = widget.get_value() NameError: global name 'obj' is not defined </code></pre> <p>I know a little about namespaces and scope, but I am very noob on Python and Object orienting in general, so I do not know exactely what I should do. Any help would be much appreciated.</p>
