[Tkinter-discuss] System Font Size

[Fuzzyman]

Hello all,

I'm creating a windows application, with a Tkinter GUI.

I currently happily set the font sizes using tuples ``font=("name",
"size", "weight")``. (or something like that.)

I use a couple of different sizes for titles, subtitles, body text and
buttons.

I would like to detect the system font size, so that I can respond to
this. (In case the user has specified larger fonts). Does anyone know
how I can do this ?

Oh, and while I'm on the subject, does anyone know of a pure Python
combobox other than the Pmw one ? The Pmw one is fine, it just means
distributing the Pmw extension with my application, and if I could
replace this with a single file I would.

All the best,

Fuzzyman

If you want to find the default font used for a particular item, create

b = Tkinter.Button(app)
b.cget("font")

'-monotype-arial-medium-r-normal-*-12-*-*-*-p-*-iso8859-15'
(in this case, it's a Linux system with the fonts coming from the X
resource database in XLFD format)

import tkFont
f = tkFont.Font(b, b.cget("font"))
fo.metrics()

{'fixed': 0, 'ascent': 11, 'descent': 3, 'linespace': 14}

fo.configure()

{'family': 'arial', 'weight': 'normal', 'overstrike': '0', 'size': '9',
'slant': 'roman', 'underline': '0'}

fo.measure("Hello World")

64

fc = fo.configure()
fc.weight = 'bold'
nf = tkFont.Font(b, **fc)
b.configure(font=nf, text="Bold Button")
b.pack()
tkFont.families(b)

('nimbus roman no9 l', 'arial black', 'clearlyu devangari extra', ...

tkFont.names(b)

('font136858972', 'font136997436')

Wow, on windows I get :

'{MS Sans Serif} 8'

That's pretty different. :-)

If I then change my system font size to "extra large" and repeat the
exercise, the default font size is unchanged. The text on the title bar
is made bigger, but buttons created have the same smaller size text.

Looks like I'll have to find a win32 way to check the system settings. :-(

Thanks anyway Jeff.

Tk font sizes are independent of Windows so looking for a win32com means
of querying the system font sizes may be required. As to your combobox
question, I don't use pmw but the combobox should be fairly simple to
create. To refresh my mem on it I looked up examples of the two types,
simple & dropdown. The simple version would be pretty easy to do with a
label and listbox. The dropdown version would be harder, but if you
don't care about the arrow icon and don't need to select multiple items
in the combobox dropdown, then an OptionMenu would be the way to go.
Another thing to consider is tying a ListBox to a Button or MenuButton.
I've never tried this but I believe I've seen others on the web say it
can be done.

here's an old module that might be useful:

Aargh... I've just integrated the Pmw one, but this looks like it might
be easier for me to customise.

Thanks, now I have to *think* and I don't like that.
