Re: [Tutor] TKinter question
My code writes to a text file 'table.txt', and 'table.txt' is displayed in
the GUI. The user can generate new data at the click of a button
which re-writes 'table.txt', but I can only add the new table to the GUI
window rather than 'update' the existing one.
class MoC:
def __init__(self, master):
frame = Frame(master, width=600, height=800, bd=1)
frame.pack()
you are not storing the widgets so they will be lost when you leave
__init__.
use self.frame, self.text etc so you can access them in other methods.
#Text box frame
text=Text(iframe5, height=10, width =70)
fd = open('table.txt') #table.txt must be in the same folder
lines = fd.read()
fd.close()
text.insert(END, lines)
This putes the lines at the end of the text box.
You want to use '1.0' as the position instead of END.
Check the documentation on the Text widget in the Tkinter
reference manual.
#Command definitions
def quit(self):
root.destroy()
def DisplayUpdate(self): #The command definition used to update the
display.
#Could I insert a line here to remove the existing frame/text box
first?
iframe5 = Frame(root, bd=2, relief=SUNKEN)
text = Text(iframe5, height=10, width =70)
This creates a new text widget rather than using the one created in init.
If you use self.text in init you can reference thatv same widget here.
fd = open('table.txt')
lines = fd.read()
fd.close()
Since you do this in two places it might be worth making it a
loadFile() method or similar?
text.insert(END, lines)
If you use '1.0' it should overwrite the old contents. However if
the second is shorter you will get remnants so you might want
to clear the contents too, look at the delete method and use
a start of '1.0' and an end of END...

Thank you very much, Rob. Hi Rob, I'm not sure what you mean with beveled/raised edges , maybe setting the widget's relief to GROOVE or RIDGE does what you want? Rounded corners are much more complicated; you will probably need the shape extension for Tk which adds non-rectangular window support to Tk. A version of shape that works with unix systems is included in the tkdnd drag and drop extension (http://sourceforge.net/projects/tkdnd); I wrote a Tkinter wrapper for tkdnd (http://www.8ung.at/klappnase/TkinterDnD/TkinterDnD.html) that makes it possible to use tkdnd from python. If you need windows support, you can try a newer version of shape (http://www.cs.man.ac.uk/~fellowsd/tcl/shapeidx.html) that seems to support windows platforms, too.

Thank you very much, Rob. Have you looked at the options for the frame class? Eg, Frame(parent, borderwidth=2, relief=RIDGE) Hi Rob, Also, some people have written some custom widget classes as part of the Python Megawidgets project: http://pmw.sourceforge.net/ But it sounds more like you might be interested in things like skinning; unfortunately, I don't know too much about that.
