That might be the case, and actually, this had crossed my mind too for a moment. But then, why is it different on Windows (where buttons have the same image action)?

I think it's set to 2 by default on a canvas; don't know about anything else. Its existence can do unexpected things to a canvas coordinate system. -- Jonathan Bromley

Buttons under MS-Windows (and MacOSX) use 'native' widgets. Under Linux/UNIX they use Tk's widget code. > > Erik. -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

My guess...I've been struggling with the same issue, so I would really like to know...is that the [winfo height/width] thing isn't necessarily a good way to measure the result of the widget creation. For instance, if I enlarge or shrink the window, the [winfo height/ width] changes, although the button remains the same size. I did the same test using ttk widgets and I get the same problem: one or two extra pixels in space all the way around. On linux, the default ttk button doesn't move: package require Tcl 8.5 package require Tk 8.5 ttk::style theme use default image create photo img -file ./favicon.gif -height 16 -width 16 ttk::button .b -image img -style B.TButton ..b configure -padding {0 0 0 0} ttk::style configure B.TButton -relief flat -padding {0 0 0 0} -width -1 -shiftrelief -1 pack .b update idletasks winfo width .b winfo height .b I get 19 (16+3) for winfo width/height. |
