bad window path name... Why ???

[maura.m...@gmail.com]

WIth the goal to shrink the GUI panel we are trying to gather some of
the pre-existing buttons together by functional areas.
The old configuration defined two labels (H and V) with assocaited
radiobuttons as follows:
____________________________________________________________________________

# Rotation radiobuttons
# frame $base.frame_panel.rbut_rot_h
# frame $base.frame_panel.rbut_rot_v

# label $base.frame_panel.rbut_rot_h.label \
# -borderwidth 0 \
# -font 7x13 \
# -text "H"

# label $base.frame_panel.rbut_rot_v.label \
# -borderwidth 0 \
# -font 7x13 \
# -text "V"

# radiobutton $base.frame_panel.rbut_rot_h.angle_0_h \
# -relief raised \
# -variable plot(rot_v) -text "0" -value 0 \
# -font "-adobe-symbol-medium-r-normal-*-14-*-*-*-*-*-*-*"

# radiobutton $base.frame_panel.rbut_rot_h.angle_pi_h \
# -relief raised \
# -variable plot(rot_v) -text "p" -value 1 \
# -font "-adobe-symbol-medium-r-normal-*-14-*-*-*-*-*-*-*"

# radiobutton $base.frame_panel.rbut_rot_v.angle_0_v \
# -relief raised \
# -variable plot(rot_h) -text "0" -value 0 \
# -font "-adobe-symbol-medium-r-normal-*-14-*-*-*-*-*-*-*"

# radiobutton $base.frame_panel.rbut_rot_v.angle_pi_v \
# -relief raised \
# -variable plot(rot_h) -text "p" -value 1 \
# -font "-adobe-symbol-medium-r-normal-*-14-*-*-*-*-*-*-*"
# pack $base.frame_panel.rbut_rot_h.label \
# $base.frame_panel.rbut_rot_h.angle_0_h \
# $base.frame_panel.rbut_rot_h.angle_pi_h \
# -side left -expand yes -fill both
# pack $base.frame_panel.rbut_rot_v.label \
# $base.frame_panel.rbut_rot_v.angle_0_v \
# $base.frame_panel.rbut_rot_v.angle_pi_v \
# -side left -expand yes -fill both

I first replace each twin radiobuttons by a tk_optionMenu. It worked
but this widget does not allow me to insert any text or label
qualifying what the menu entries are for. I mean what appeared on the
GUI panel was just the currently selected respective radiobutton
values.
Since the above is supposed to allow the user for rotating the
canvas-displayed graphics either around a vertical or a horizontal
axis, I think the user should somehow know the rotation direction when
selecting the rotation angle ...
To try and solve this problem I created two menubuttons whose child is
respectively the menu returned by tk_optionMenu. Both menubutton are
contained in the same frame that is then placed in the panel grid.
So far I had not been successful at making this work. I fixed some
child-parent path Tcl was complaining about. I fixed the outermost
window name as Tcl does not like capitol letters. Still now it's
returning the following error:

bad window path name ".frame_panel.rbut.rot_h"

I cannot make a sense out of this message. Why is it a bad window
pathname ?
In the following I've pasted my new code.
Thank you in advance for your assistance.

You have created a frame named $base.frame_panel.rbut, and then created
an option menu named $base.frame_panel.rbug.rot_h.om. Nowhere have you
created the widget $base.frame_panel.rbut.rot_h. Hence, the error
message you see complaining about "...rot_h"

The window path is not defined at the time the [set menu_H] command is
executed. Try putting the [menubutton] commands before the [set munu]
commands.
