[Bug 2036760] [NEW] tcl/tk BWidget ProgressDlg does not open correctly

[Fredrik Bennison]

Public bug reported:

There is an issue with opening BWidget ProgressDlg when running Ubuntu
23.04.  The problem is not present in Ubuntu 22.04.

Ubuntu release:

sysop at vb2304:~$ lsb_release -rd
No LSB modules are available.
Description:	Ubuntu 23.04
Release:	23.04

Package version:

sysop at vb2304:~$ apt-cache policy tk8.6
tk8.6:
  Installed: 8.6.13-2


To reproduce:

Install new Ubuntu 23.04 and install bwidget package with 'apt install
bwidget'-

Create a tcl file with this content:

=====================
package require Tk
package require BWidget

variable value
variable txtvar

ProgressDlg .p -type normal -variable value -maximum 100 -title "Titel"
-textvariable txtvar

set txtvar "Test text"
set value 1

puts [info patchlevel]
while {$value < 100 } {
  set value [expr {$value + 1}] 
  puts "value is $value"
  exec sleep 0.1
}
=====================

Run the file with:

wish test.tcl

Expected result:   A progress bar appears counting filling up from 1 to
100.  Test printout in shell window:

8.6.13
value is 2
value is 3
value is 4
....


This happens when running the same file in Ubuntu 22.04.

What happens instead:

Wish window appears, but no progress bar dialog.  When closing the wish
window the follow appears in the shell window:

sysop at vb2304:~$ wish test.tcl 
Error in startup script: window ".p" was deleted before its visibility changed
    while executing
"tkwait visibility $path"
    (procedure "Dialog::draw" line 57)
    invoked from within
"Dialog::draw $path"
    (procedure "::ProgressDlg::create" line 26)
    invoked from within
"ProgressDlg .p -type normal -variable value -maximum 100 -title "Titel" -textvariable txtvar"
    (file "test.tcl" line 7)


Occasionally the first run of 'wish test.tcl' works but not subsequent calls.
