This file is generated by the /usr/local/libexec/nscde/generate_subpanels.
It is static in system directory, but changable and easly generated in the $FVWM_USERDIR
It contains FvwmButtons(8) definitions of all 10 possible subpanels which can be popped up from the
Front Panel. There are 3 ways to regenerate this file:
Subpanels Manager tool called from
the Install Icon, Subpanel Settings tool
called from the titlebar popdown menu on every subpanel as Subpanel Settings or
manually by calling /usr/local/libexec/nscde/generate_subpanels which will
read user's or system Subpanels.actions
for
every subpanel and if it is defined in user's one, take this one while generating NsCDE-Subpanels.conf.
In system default, subpanels 2, 5 and 6 are disabled by default, but can be activated with a very quick
double middle pointer click on the empty launcher without arrow: a
Subpanel Settings application will appear on the screen
which has a checkbox "This Subpanel is Enabled" which will be checked out by
default, and can be checked in, and will enable subpanel with initial
system defaults for name, width and application entries.
