[Tkinter-discuss] Combining Tcl/Tck widgets with a Xll Graphics window

[Jeff Epler]

The "frame" widget has this option (from the tk manpage):
       Command-Line Name:-container
       Database Name:  container
       Database Class: Container

              The value must be a boolean.  If true, it means that this window
              will be used as a container in which some other application will
              be embedded (for example, a Tk toplevel can  be  embedded  using
              the  -use option).  The window will support the appropriate win‐
              dow manager protocols for things like  geometry  requests.   The
              window  should not have any children of its own in this applica‐
              tion.  This option may not be changed with the configure  widget
              command.

However, actually using this option seems to lead to focus-related headaches.

Anyhow, here's a program that embeds an ImageMagick "display" into a Tk frame:
#-----------------------------------------------------------------------
import Tkinter, sys, os

t = Tkinter.Tk()
b = Tkinter.Button(text="quit", command=t.destroy)
f = Tkinter.Frame(container=True, width=300, height=300, bg="")
f.pack(side="top")
b.pack(side="top")
os.spawnvp(os.P_NOWAIT, 'display', ['display',
    '-window', hex(f.winfo_id()),
    '-window_group', hex(f.winfo_id()), sys.argv[1]])
t.mainloop()
#-----------------------------------------------------------------------
