Summary: font specification error

Initial Comment:
As raised on c.l.t by Adrian Davis:

It seems there may be a (minor) bug setting the font for a (Tk/ttk)
label widget, which causes an "expected integer ..." error.

It appears to happen only in a very specific circumstance...

When all of the following are true:-

*) The "-family" option name contains a hyphen/dash.
*) The "-family" option appears first in the list.
*) All of the "-size", "-weight", "-slant", "-underline" and "-overstrike" options are specified.

For Example...

.mylabel configure -font {-family sans-serif -size 12 -weight bold -slant roman -underline 0 -overstrike 0}

...Doesn't work. But...

.mylabel configure -font {-family times -size 12 -weight bold -slant roman -underline 0 -overstrike 0}

.mylabel configure -font {-size 12 -family sans-serif -weight bold -slant roman -underline 0 -overstrike 0}

.mylabel configure -font {-family sans-serif -size 12 -weight bold -slant roman -underline 0}

...All work Ok.

I found this using Tcl/Tk 8.5.7 on Solaris 10.

This has been reproduced under WinXP using ActiveTcl 8.5.3 and Ubuntu
using ActiveTcl 8.6b1.1

(See thread: http://groups.google.co.uk/group/comp.lang.tcl/browse_thread/thread/aa2a4f206c139c42?hl=en#)

WORKAROUND: Make sure that the "-family" option doesn't appear first
in the list.

Best Regards,
   =Adrian=

Occurs on Windows as well. The following test will reveal the issue:

-underline 0 -overstrike 0}
