Regarding my questions, I guess both are impossible in Tkinter (as I didn't found anything about that in any Tkinter documentation), but there still must be a way to get the default OS font name and size (maybe outside of Tkinter), because it's always advised to use them in applications. Otherwise text, for example, will always be too large or too small on some screens. -- http://mail.python.org/mailman/listinfo/python-list

Go to: http://www.pythonware.com/library/tkinter/introduction/ Read chapter 6, Widget Styling, there is a section on Fonts which has a sub-section on System Fonts. None of them is suitable as a default text font. Prior to Tk 8.5, there is no way to get the right fonts used by the OS/desktop/theme. Tk 8.5 may provide that, but I haven't got it yet (see http://www.tcl.tk/cgi-bin/tct/tip/145.html) Regarding my questions, I guess both are impossible in Tkinter (as I didn't found anything about that in any Tkinter documentation), but there still must be a way to get the default OS font name and size (maybe outside of Tkinter), because it's always advised to use them in applications. Yes. Your second question is easy; google for tkinter default font. To obtain the desired font description, on Windows, you can use the pywin32 package or ctypes to call the following functions, and then configure Tkinter to use the desired font by default. Use SystemParametersInfo(SPI_GETNONCLIENTMETRICS,...) to obtain a NONCLIENTMETRICS structure. From it, obtain the lfMessageFont field (this is the default font for message boxes; you may be interested on others too, like lfMenuFont). It has all the info you need: lfFaceName is the font name, the various flags determine the font style, note that bold == lfWeight=500. Maybe lfHeight it's a bit complicated; it's the height in pixels, to convert to points (1/72): hdc = GetDC(0) dpi = GetDeviceCaps(hdc, LOGPIXELSY) font_size = int(round(abs(lfHeight) * 72 / dpi)) ReleaseDC(0, hdc) -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
Tkinter fonts setting
First question - is it possible to set font to default OS font for window text? It would be preferable, while on my Windows XP system Tkinter sets small Helvetica-style font by default. Secondly, can I set font globally (or specify default font for widgets)? In fact, all I want is to get default OS font unless (rarely) I need to specify another.
