NAME
raise - Change a window's position in the stacking order
SYNOPSIS
raise window ?aboveThis?
______________________________________________________________________________
DESCRIPTION
If the aboveThis argument is omitted then the command raises window so
that it is above all of its siblings in the stacking order (it will not
be obscured by any siblings and will obscure any siblings that overlap
it). If aboveThis is specified then it must be the path name of a
window that is either a sibling of window or the descendant of a
sibling of window. In this case the raise command will insert window
into the stacking order just above aboveThis (or the ancestor of
aboveThis that is a sibling of window); this could end up either
raising or lowering window.
All toplevel windows may be restacked with respect to each other,
whatever their relative path names, but the window manager is not
obligated to strictly honor requests to restack.
On macOS raising an iconified toplevel window causes it to be
deiconified.
EXAMPLE
Make a button appear to be in a sibling frame that was created after
it. This is is often necessary when building GUIs in the style where
you create your activity widgets first before laying them out on the
display:
button .b -text "Hi there!"
pack [frame .f -background blue]
pack [label .f.l1 -text "This is above"]
pack .b -in .f
pack [label .f.l2 -text "This is below"]
raise .b
