Hi all,
Tried sending a couple of e-mails not realizing I am not subscribed to dev
list... DOH! So, please prepare for a small salvo of e-mails :-)
Topic #1: tcl/tk 8.5 help browser bug
This help browser bug using CVS and tcl/tk 8.5 has been present since at least
last fall. After digging through the code, I found the following:
proc doc_make_listbox {base dir count} {
# check for [file readable]?
if { [info tclversion] >= 8.5 } {
# requires Tcl 8.5 but probably deals with special chars better
# destroy {expand}[lrange [winfo children $base] [expr {2 * $count}] end]
} else {
The comment before "destroy" in effect disables destroying of children widgets
and causes errors whenever I have more than one column open and try to click on
a column preceding one that is already created. The error reported is that the
"listbox1-list already exists" and the only way around is to close the help
browser and reopen it. This obviously prevents going up the file tree once a
particular subfolder has been opened which obviously means it is a non-lethal
bug, but nonetheless annoying.
The fix is obvious, remove the comment from the offending line and everything
works like a charm:
proc doc_make_listbox {base dir count} {
# check for [file readable]?
if { [info tclversion] >= 8.5 } {
# requires Tcl 8.5 but probably deals with special chars better
destroy {expand}[lrange [winfo children $base] [expr {2 * $count}] end]
} else {
It would be great if one of the devs/maintiners would please commit this change
(I'd do it but I have not bothered to get the CVS dev access).
Many thanks!
Best wishes,
Ico
