[Tutor] Entry box + browse button

[Kent Johnson]

Klas,

One thing you can do is connect the entry widgets to Tk Variables. Then any 
change to the Variable will be reflected in the Entry and vice versa. By 
having the Browse button set the Variable it will show up in the Entry. In 
doProcessFiles() you read the value of the Variable.

Here are the changes needed to your program to set this up for the input file:
- Create infile and inputEntry like this:
         self.infile = StringVar()
         self.infile.set("/home/klas/Python_filer/Tragic/ebom_from_file_wider.txt")

         self.inputEntry = Entry(master)
         self.inputEntry["textvariable"] = self.infile
         self.inputEntry.grid(row=0,column=1)

- openFile() looks like this:
     def openFile(self):
         import tkFileDialog
         self.infile.set(tkFileDialog.askopenfilename())

- In doProcessFiles() change
         inputFileName = self.inputEntry.get()
to
         inputFileName = self.infile.get()

You have to make similar changes for the outputEntry.

I hope I have correctly understood what you are trying to do!
