HELP: Python & Tkinter ?

[PGMoscatt]

Hi all,

Have just installed Fedora 3 and wish also want to give programming with
Python a go.  I wish to develop GUI interfaces and believe that 'Tkinter'
is the way to go.

After installing Python frpm the distro CD I can't use the 'from Tkinter
import *' command. When I try, I get the error message below:

ImportError: No module named Tkinter

So from that I assume I need to install Tkinter ?
Should I also find this on the CD ?  Is it known as another name as looking
on the CD I don't seem to find anything relating to Tkinter.

Thanks in advance.

Pete

Thanks Fredrik, yep, that did the trick.  Never seen this YUM thing but it's
pretty trick.

Globals between modules ?

[PGMoscatt]

Does Python allow a 'global' variable that can be used between different
modules used within an app ?

Thanks Roy  yep, that makes sense.

Widget geometry ?

[PGMoscatt]

Hi All,

I am trying to create a dialog which will have a number of components but
having trouble with the placement of various widgets.

For example, in my code below you will see I am trying to insert alabel but
I want the label to be in the top-left of the dialog but it dosen't want to
go there.

What am I doing wrong ?

Pete



from Tkinter import *

class show_settings_dialog:
 def __init__(self,parent):
  top = self.top = Toplevel(parent)
  top.title("General Settings...")
  top["height"]=300
  top["width"]=300
  top.pack_propagate(0)

  l1 = Label(top,text="User Name:").grid(row=0, sticky=W)

  b = Button(top,text="Ok",command=self.ok)
  b.pack(pady=40)
  
  
  
 def ok(self):
  self.top.destroy()

Bitmaps On Buttons ?

[PGMoscatt]

I am slowly progressing with my python app.

I have got to the point where I would like to place images onto my buttons. 
I use Tkinter as my GUI libary.

The following is how I understand I place an image onto a button - but I am
not having much success with it all.

Any ideas ?

Pete

b=Button(ToolBar,padx=1,pady=1,width=2,height=1,command=callquit,)
b.bitmap="@button_cancel.xbm"
b.place(x=0,y=0)
