Events Group: None Status: Open Resolution: None Priority: 9 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Joe English (jenglish) Summary: [bind] error - event parsing? Initial Comment: After installation of Tk8.5.3 (with Tcl8.5.3) I get for several (all?) application the following error on startup fr Application initialization failed: Can't find a usable tk.tcl in the following directories: /usr/local/beta/lib/tcl8.5/tk8.5 /usr/local/beta/lib/tk8.5 /usr/local/lib/tk8.5 /usr/local/beta/library /usr/local/beta/lib/tk8.5/tk.tcl: no event type or button # or keysym no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }" invoked from within "if {[tk windowingsystem] eq "aqua"} { bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D)}] units } bind Listbox <Option-Mou..." (file "/usr/local/beta/lib/tk8.5/listbox.tcl" line 182) invoked from within "source /usr/local/beta/lib/tk8.5/listbox.tcl" (in namespace eval "::" script line 1) invoked from within "namespace eval :: [list source [file join $::tk_library $file.tcl]]" (procedure "SourceLibFile" line 2) invoked from within "SourceLibFile listbox" (in namespace eval "::tk" script line 4) invoked from within "namespace eval ::tk { SourceLibFile button SourceLibFile entry SourceLibFile listbox SourceLibFile menu SourceLibFile panedwindow SourceLibFile ..." invoked from within "if {$::tk_library ne ""} { proc ::tk::SourceLibFile {file} { namespace eval :: [list source [file join $::tk_library $file.tcl]] } ..."

At the moment, Tcl8.5.3 (compiled with gcc-4.3.1 -O3) together with my previous Tk8.5.2 (compiled with gcc-4.2.4 -O3) works just fine.

It's Tile extension. ---------------------------------------------------------------------- Comment By: Donal K. Fellows (dkf) Date: 2008-07-11 02:03 Message: Logged In: YES user_id=79902 Originator: NO Further examination indicates that it is not possible to prevent the delivery of GenericEvents to Tk without abandoning the use of all extensions (XIM being the one we need more than any other, alas). Now, if generic events had been structured as an extension, we wouldn't have been bitten. But they weren't so we were. Principal concern: whether there are any extensions that use Tk's faked up MouseWheel, Activate and Deactivate event numbers directly (instead of using a binding table). If not, we can just fix Tk and everyone else will come along for the ride. ---------------------------------------------------------------------- Comment By: Joe English (jenglish) Date: 2008-07-10 08:31 Message: Logged In: YES user_id=68433 Originator: NO Cause of the problem: parts of Tk have a hardcoded assumption that the X11 protocol constant LASTEvent is #defined to be exactly 35 (== MappingNotify + 1). In particular: the 'flagArray' and 'eventMasks' static array initializers in tkBind.c resp. tkEvent.c; possibly others as well. This has been a valid assumption (from 1991 up until very recently), but X.org xproto-7.0.13 added a new "GenericEvent" event type and incremented LASTEvent. This problem affects all versions of Tk from 4.0 through 8.6a1, as well as any extensions that reference the Tk extension event types VirtualEvent, ActivateNotify, DeactivateNotify, and MouseWheelEvent. Proposed short-term fix: replace all uses of the symbolic constant LASTEvent with MappingNotify+1. This should restore source-level compatibility with newer Xlib releases and preserve ABI compatibility for Tk extensions. Conflicts between Tk "VirtualEvent" events and X11 "GenericEvent" events should not be a problem -- Tk does not select for GenericEvents, so it should never receive any from the X server (@@@ need to confirm this). Long-term fix needs further discussion. ---------------------------------------------------------------------- Comment By: Sergei Golovan (teopetuk) Date: 2008-07-09 23:13 Message: Logged In: YES user_id=410366 Originator: NO The following bug in gentoo shows that the problem is in an incompatible changes in xproto-7.0.13: http://bugs.gentoo.org/show_bug.cgi?id=225999 (or it's a Tk fault where it cannot survive a new event in X protocol?) ---------------------------------------------------------------------- Comment By: Don Porter (dgp) Date: 2008-07-07 19:28 Message: Logged In: YES user_id=80530 Originator: NO Error is reported at runtime, not a flaw in building. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=112997&aid=2010422&group_id=12997 |
