Not in my sh!
The classic error is to run the environment script normally, as a child, and then only that child and its children get to see it, but then that child and its children end and the parent and next child are unaffected.
The trick is that after you set a variable, only you see it, but when you export the variable, the receiving process will be your child. The ". myscript" sourcing above runs the script in the current shell so it affects you and your children.
Scripts pathed $HOME/.(shell_name)rc like ~/.kshrc and ~/.bashrc are run automatically as the ksh or bash process comes to life, which is nice but excessively often, as script calls script after script. The bourne shell sh only uses ~/.profile, but for that reason and the superset offered in ksh, few people use it interactively. Other shell programs run ~/.profile once for the login shell only.

xtmanagechildren
XtManageChildren(3X) XT FUNCTIONS XtManageChildren(3X)NAME
XtManageChildren - manage children
SYNTAX
void XtManageChildren(children, num_children)
WidgetList children;
Cardinal num_children;
ARGUMENTS
children Specifies a list of child widgets.
num_children
Specifies the number of children.
DESCRIPTION
The XtManageChildren function performs the following:
o Issues an error if the children do not all have the same parent or if the parent is not a subclass of compositeWidgetClass.
o Returns immediately if the common parent is being destroyed; otherwise, for each unique child on the list, XtManageChildren ignores
the child if it already is managed or is being destroyed and marks it if not.
o If the parent is realized and after all children have been marked, it makes some of the newly managed children viewable:
- Calls the change_managed routine of the widgets' parent.
- Calls XtRealizeWidget on each previously unmanaged child that is unrealized.
- Maps each previously unmanaged child that has map_when_managed True.
Managing children is independent of the ordering of children and independent of creating and deleting children. The layout routine of the
parent should consider children whose managed field is True and should ignore all other children. Note that some composite widgets, espe-
cially fixed boxes, call XtManageChild from their insert_child procedure.
If the parent widget is realized, its change_managed procedure is called to notify it that its set of managed children has changed. The
parent can reposition and resize any of its children. It moves each child as needed by calling XtMoveWidget, which first updates the x and
y fields and then calls XMoveWindow if the widget is realized.
