Hi.

Does this demonstration help?
Code:
#!/usr/bin/env bash

# @(#) s1       Demonstrate calling function from find -exec.

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
LC_ALL=C ; LANG=C ; export LC_ALL LANG
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
em() { pe "$*" >&2 ; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C

function a_function {

FIRST_PARAM="$1"
SECOND_PARAM="$2"
THIRD_PARAM="$3"
fourth="$4"

echo DO_SOMETHING "$FIRST_PARAM" "$SECOND_PARAM" "$THIRD_PARAM" "$fourth"

}

pl " Current files f?:"
echo f?

export -f  a_function

START_HERE="/home/some_user/Documents"
VARIABLE_1="VALUE_1"
VARIABLE_2="VALUE_2"

pl " Results:"
# find $START_HERE"  -exec bash -c 'a_function "$0" ' {}  "$VARIABLE_1"   "$VARIABLE_2" \;
find .  -name 'f?' -exec bash -c "a_function $0 {}  $VARIABLE_1 $VARIABLE_2" \;

producing:
Code:
$ ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 3.16.0-4-amd64, x86_64
Distribution        : Debian 8.9 (jessie) 
bash GNU bash 4.3.30

-----
 Current files f?:
f1 f2 f3

-----
 Results:
DO_SOMETHING ./s1 ./f1 VALUE_1 VALUE_2
DO_SOMETHING ./s1 ./f2 VALUE_1 VALUE_2
DO_SOMETHING ./s1 ./f3 VALUE_1 VALUE_2

I used local directory with only f* files for brevity.

Best wishes ... cheers, drl

xmscrollvisible

XmScrollVisible(3X)													       XmScrollVisible(3X)

NAME

       XmScrollVisible - A ScrolledWindow function that makes an invisible descendant of a ScrolledWindow work area visible

SYNOPSIS

       #include <Xm/ScrolledW.h>

       void XmScrollVisible (scrollw_widget, widget, left_right_margin, top_bottom_margin)
	       Widget scrollw_widget;
	       Widget widget;
	       Dimension left_right_margin;
	       Dimension top_bottom_margin;

DESCRIPTION

       XmScrollVisible	makes  an  obscured or partially obscured widget or gadget descendant of a ScrolledWindow work area visible.  The function
       repositions the work area and sets the specified margins between the widget and the nearest viewport boundary.  The widget's location rela-
       tive to the viewport determines whether one or both of the margins must be adjusted.  This function requires that the XmNscrollingPolicy of
       the ScrolledWindow widget be set to XmAUTOMATIC.  Specifies the ID of the ScrolledWindow widget whose work area window contains an obscured
       descendant.   Specifies	the  ID of the widget to be made visible.  Specifies the margin to establish between the left or right edge of the
       widget and the associated edge of the viewport. This margin is established only if the widget must be moved horizontally to make  it  visi-
       ble.   Specifies  the margin to establish between the top or bottom edge of the widget and the associated edge of the viewport. This margin
       is established only if the widget must be moved vertically to make it visible.

       For a complete definition of ScrolledWindow and its associated resources, see XmScrolledWindow(3X).
