hi all,
from the doc of the spinbox, abou the -command option :
Specifies a Tcl command to invoke whenever a spinbutton is invoked.
The command recognizes several percent substitutions: %W for the
widget path, %s for the current value of the widget, and %d for the
direction of the button pressed (up or down).

my goal is to know if up or down button is pressed, but the %d
substitution return computer-crash (at least ;-) ) value.
am i right or my code is wrong?

best regards,
swan

Hi Swan,

Welcome to the Google Gnocl Group.

I think that your problem is not with gnocl, are you using Tk because
there is no -command option in gnocl. The gnocl::spinButton, which is
direct wrap arounf the GtkSpinButton widget has no handler to
determine which of the control arrows has been pressed.

http://library.gnome.org/devel/gtk/2.16/GtkSpinButton.html#GtkSpinButton.signals

A gnocl::spinButton will respond to an -onValueChanged signal and
return the value contained in the spinButton object, but does not have
a %d substitution string.
