I've run into some strange bug where an application randomly flash
exits once I select over 154 items in a tixScrolledListBox.  The
flash exit leaves with messages concerning also
Tk_CreateErrorHandler failing and Tcl_Panic being invoked!  The
application terminates with the Abort signal.

I found that the problem is remedied by configuring this widget with
the "-exportselection false" option.  This makes me believe there is
something funny with the clip mechanism between tix and the X
selection.  The limit of 154 is specific to this one widget and I
found a limit of 300 or so items for another widget in the
application (before weird things happen).

Is this a known problem?  Has it been fixed in tix8.1?

It seems to occur less frequently with the more modern packages under
RedHat Enterprise 3.0.  We need to support this application on RH 7.3
though so I'm very curious about this!  Thanks for any info out there-

I was wondering if there were a way to execute a command upon closing
a window.  It's clear to me how a procedure could get executed in
conjuntion with the destroy command; what I haven't been able to
figure out is how to have a command executed when a user kills a
window by clicking the "X" in the upper right-hand corner.  Is there a
way to bind a command to that particular way of closing a window?  I
apologize if this question is better posed to another list, perhaps
related to wish or tcl/tk - it isn't always clear to me what the
boundaries are between these.  Thanks - John

It is a window manager command, part of Tk. You do:

    wm protocol WM_DELETE_WINDOW "whatever you wanna do"

Dear Techies,

    I am searching for a solution to pass the TCL Arrays in C
Subroutine/function. But i am unable to do so.
    I have passed simple int variables from Tcl Script, changed the
value  from C function and then printed back with Tcl Script. I used
Tcl_LinkVar() function to achieve this.
    Pls, help me how can i pass arrays and manipulate in C function and
get back to Tcl Script.

    Thanking U.
