#37710 — Fonts & Tinker

I am changing the default font for a Tkinter application:

class FuelControl(Tkinter.Frame):
    def __init__(self,master):
        self.version='0.02'
        self.font=tkFont.Font(family="Helvetica",size=18) 
        print self.font.actual()
.
.
.

and everything looks ok:

{'family': 'Nimbus Sans L', 'weight': 'normal', 'slant': 'roman', 'overstrike': 0, 'underline': 0, 'size': 18}

and the size of the text are 18 on the screen. Then a button creates a new window through this callback:

    def loc_add(self):
        addw=Tix.Tk()
        addw.title('Add location')
        print self.font.actual()
        Tkinter.Label(addw,text='Nickname:', font=self.font).grid(row=0,column=0)
        Tkinter.Label(addw,text='Fullname:', font=self.font).grid(row=1,column=0)
        Tkinter.Label(addw,text='Address:',  font=self.font).grid(row=2,column=0)
        Tkinter.Label(addw,text='Fuel name:',font=self.font).grid(row=3,column=0)
...

The self.font stays with the right value:

{'family': 'Nimbus Sans L', 'weight': 'normal', 'slant': 'roman', 'overstrike': 0, 'underline': 0, 'size': 18}

but the real displayed fonts in the window are smaller (default size of 12, maybe).

Am I missing something?

Thanks in advance,
A.

You may want to check out these universal Tkinter widget methods:

 w.option_add(pattern, value, priority=None)
 w.option_clear()
 w.option_get(name, classname)
 w.option_readfile(fileName, priority=None)

 http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/universal.html

While you are there, poke around the docs a bit because there is tons of good info you are going to need in the future. May want to get familiar with the new ttk widgets and themes.

Did you tried this by simple:

---------------------------
root = Tk()
root.option_add('*Font', "Heveltica 14")
---------------------------

We'll see if it's a local tkinter installation problem.
