Hi all,
I don't know how the help browser works (Hans-Christophe wrote it) and don't know whether that comment character is in there for some reason or not. So I'm scared to fix this without hearing from HC.
I wonder if the old-fashioned idea of just using the file browser should be available as at least an option...
cheers Miller

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,
