Limitations: text tags are saved but their individual configurations are not. text marks, images, and windows are not saved. listbox item configurations are not saved. panedwindows are not totally saved. these should be trivial to add if someone wants to.
Usage example:
set state [serialize .frame] destroy .frame toplevel .frame eval [join $state \;]
--AF 23-06-03
}
proc serialize {w} {
upvar state state
foreach c [winfo children $w] {
set new $c
if {[catch {$c configure -class} widget]} {set widget "{} {} {} [winfo class $c]"}
set widget [string tolower [lindex $widget 3]]
set args {}
foreach x [$c configure] {
if {[set opt [lindex $x 4]] != [lindex $x 3]} {lappend args [list [lindex $x 0] $opt]}
}
lappend state "$widget $new [join $args]"
if {$widget == "listbox"} {
lappend state "$new insert 0 [$c get 0 end]"
} elseif {$widget == "entry"} {
lappend state "$new configure -state normal"
lappend state "$new insert 0 [list [$c get]]"
lappend state "$new configure -state [$c cget -state]"
} elseif {$widget == "text"} {
lappend state "$new configure -state normal"
lappend state "$new insert 1.0 [list [$c get 0.0 end-1c]]"
lappend state "$new delete end end-1l"
lappend state "addtags $new [list [$c dump -tag 0.0 end]]"
lappend state "$new configure -state [$c cget -state]"
} elseif {$widget == "menu"} {
set end [$c index end]
for {set x 0} {$x <= $end} {incr x} {
set config {}
foreach arg [$c entryconfigure $x] {
if {[set opt [lindex $arg 4]] != ""} {lappend config "[lindex $arg 0] [list $opt]"}
}
