Hello,
I am currently just starting to learn the basics of the tkinter module and ive
run into a problem. To teach myself I am messing around by creating separate
modules containing basic GUI apps like a tip calculator and kilometer
converter, then creating a main program that displays buttons you can click
that will create instances of the modules (tip calculator, kilometer
converter). So far ive managed to successfully make the basic GUI apps works
just fine, and have been able to import them into my main program and get them
to launch in a new window when i click the buttons and everything, but heres my
problem.
Everything displays ok, like the labels, entry boxes, and buttons, but when I
actually click the buttons (which are supposed to trigger a method within the
module and display a label containing the calculated data).. nothing happens.
When I run the modules by themselves everything works just fine (testing by
making the module create an instance of itself but i # them out before running
the main program)
Make the boilerplate test code conditional, something like
if __name__ == '__main__':
root = tkinter.Tk()
app = MainClass(root) # 'MainClass' depends on the module.
root.mainloop
root.destroy
and you do not need to comment it out as it will be ignored when the
module is imported.
I have posted all my code to this forum if you need to look at it
http://python-forum.org/viewtopic.php?f=12&t=5620
Code comments: double and triple spacing code make it painful to read,
especiallly in a 10 line box.
self.miles_button = tkinter.Button(self.frame3, \
text = 'Miles', \
command = self.conv_miles)
Leave off the unneeded \s.
Any idea what im doing wrong here?
You got the answer there -- only one mainloop. Revising the code as
suggested above will do that.
Note: I am a tkinter beginner too, so I would also have to experiment
with details to get importable custom widgets, built from tk widgets, right.
