Simple Tk8 Problems

[Nick Bower]

Hi,

I'm currently having 2 simple, but I think fundamental, problems with my
understanding of Tk 8.

1.  I can't control the size of the Tk root window.  I've tried putting
".width=xxx" statements everywhere in the following snippet, but nothing
seems to work.  (The FileList is a ListBox next to a scrollbar).  Is
there something I'm missing?.

class FileList(Frame):
  def __init__(self,parent):
    Frame.__init__(self,parent)
    self.filelist=Listbox(self)
    self.scroll=Scrollbar(self)
    self.filelist.config(yscrollcommand=self.scroll.set,relief=SUNKEN)
    self.filelist.pack(side=LEFT,expand=YES,fill=BOTH)
    self.scroll.config(command=self.filelist.yview,relief=SUNKEN)
    self.scroll.pack(side=RIGHT,expand=NO,fill=Y)

<etc>

if __name__ == '__main__':
  toplevel = Tk()
  afilelist=FileList(toplevel)
  afilelist.pack(expand=YES,fill=BOTH)
  afilelist.mainloop()


2. Also, the Listbox in the above code is scrolling all over the place
tracking the mouse movement as it runs across the top of it.  I don't
even need to touch the scrollbar and it seems to track mouse movement so
somehow it's been bound to the mouse as well as the scroll bar.  Weird.


Thanks in advance for help (again)  :)
