I'm specifically asking about binding a keyboard keystroke to a button in a GUI. Originally I planned to bind the keystroke to the GUI button itself, but that seemed impossible, and potentially unwise after I considered it later.`
Is this the proper(, pythonic) way to bind a keyboard key and GUI button?
## start.py
print 'start'
#from tkinter import *
from Tkinter import *
import os
from PIL import ImageTk, Image
class MyClass:
'''This is my class.'''
imgpath = '/Users/user/Dropbox/Camera Uploads'
imgfile = 'susshi.jpg'
#imgfilepath = os.path.join(self.imgpath, self.imgfile)
imgfilepath = os.path.join(imgpath, imgfile)
def __init__(self,master):
print 'in __init__'
# Create and load a frame into the tk (tkinter) window.
frame = Frame(master)
frame.pack()
# Create and load two buttons in to the above-created frame.
self.button = Button(frame, text="QUIT", fg="red", command=quit)
self.button.pack(side=LEFT)
self.slogan = Button(frame, text="Hello", command = self.f)
self.slogan.pack(side=RIGHT)
# Bind a key to each button from above.
master.bind('q', quit)
master.bind('f', self.f)
# Open the image, resize it...
self.image = Image.open(self.imgfilepath)
self.image.thumbnail((600,600))
# Make a tkinter-friendly image object ...
self.display_image = ImageTk.PhotoImage(self.image)
# Make a tkinter canvas, plug in the image, and pack the canvas.
self.canvas = Canvas(master, bg='red')
self.canvas.create_image(0,0, image=self.display_image, anchor="nw")
self.canvas.pack(fill=BOTH, expand=1)
### FIXME: Set canvas focus!
def f(self, event=None):
print 'in f()'
return 'hello world'
def get_image_list(self):
pass
def next_image(self):
pass
def previous_image(self):
pass
def load_image(self):
#stub
pass
def update_image(self):
pass
root = Tk()
abc = MyClass(root)
root.mainloop()
print 'abc has been defined'
print '"abc.f()" returns "%s"' % abc.f()
#print str(abc.f)
#print repr(abc.f)
print 'end'
The intention of the project is to make a simple image viewer in python, with buttons in the GUI for basic navigation functions, and keys mapped to those same functions.
This is the actual code I'm using. I haven't implemented the other functions yet, and I was hoping to just get the code implemented thus-far reviewed. In fact, the original question was just asking about reviewing one specific portion of the code - that is, the binding of the keystrokes in association with the buttons in the GUI. However, that specific-level of question was downvoted and given a recommendation to adhere to the guidance in the help center. I understand there may be a common issue of incomplete code segments posted, but I have truly included the entire module.
