I've just installed the Tcl/Tk 8.7a's.
In https://www.tcl.tk/man/tcl8.7/TkCmd/systray.html two egs are given.
The first one fails with:

Error in startup script: systray not created
while executing
"tk systray configure -image book_page -text "Updated sample" \
-button1 {puts "Different output from the tk systray"} \
-button3 {puts "and more dif..."
(file "/tmp/a.tcl" line 3)

But the second one works. However, the second one also creates a spurious main window, so I think the complete second example should be this:

#!/usr/bin/env wish
image create photo book -data R0lGODlhDwAPAKIAAP//////AP8AAMDAwICAgAAAAAAAAAAAACwAAAAADwAPAAADSQhA2u5ksPeKABKSCaya29d4WKgERFF0l1IMQCAKatvBJ0OTdzzXI1xMB3TBZAvATtB6NSLKleXi3OBoLqrVgc0yv+DVSEUuFxIAOw==
tk systray create -image book -text "tk systray sample" \
-button1 {puts "Here is the tk systray output"} \
-button3 {puts "here is alternate output"}
wm withdraw .

(Note that the line starting `image create` is a single line up to and including the `==` at the end.)

Hi Mark,
it would be great, if you could try:
- TCL fossil main (9.0) or fossil core-8-branch (8.7)
- Tk fossil main (8.7) branch
You should compile on your own. Some wizards are able to extract the
binaries from the github actions, but not me.
I suppose, many bugs are already fixed there.

If you are on Windows, TWAPI has great systray capabilities.

Thank you and take care,
Harald

Hi Harald,

I tried with Tcl8.7/Tk8.7 and Tcl9.0/Tk8.7. In both cases I had to add the `wm withdraw .` command. Here's the code I used:

#!/usr/bin/env wish
puts "Tcl v$tcl_version/Tk v$tk_version"
image create photo book -data R0lGODlhDwAPAKIAAP//////AP8AAMDAwICAgAAAAAAAAAAAACwAAAAADwAPAAADSQhA2u5ksPeKABKSCaya29d4WKgERFF0l1IMQCAKatvBJ0OTdzzXI1xMB3TBZAvATtB6NSLKleXi3OBoLqrVgc0yv+DVSEUuFxIAOw=tk systray create -image book -text "tk systray sample" \
-button1 {puts "Here is the tk systray output"} \
-button3 {puts "Quit"; exit }
wm withdraw .

Hi Mark,
I suppose, you are also on Xfce 4.16 on Debian 11, as on your other
post. The "wm widthdraw ." is required, that is ok.
If the error arrives in a fossil checkout of TCL main/Tk main and
compiled by your own, thaen this is a bug and should be reported as a
ticket on fossil tk:
core.tcl-lang.org/tk
I am on WIndows only. Maybe, others including Kevin who designed that
may comment. But a ticket is IMHO the best way to report.

Take care,
Harald

Added a ticket that refers to this conversation: https://core.tcl-lang.org/tk/tktview/3d10c64866be5c3b371f72859a1e5f00d4caa699

Thank you. I doubt, that a link to a google groups is a valid content
for a ticket. My company is not allowed to use google groups due to
European data protection laws. So we are out anyway. If you really would
like to get an answer, a clear ticket with platform, versions, supposed
behaviour, recognized behaviour is required, sorry.

Take care,
Harald

I think this is the intended behaviour, is it not? The "." window always
appears when you start wish; the [tk systray] adds an icon to the
systray, but does not magically hide the root window. It is only logical
that you need to withdraw it in case you want a systray-only
application. About the other error I have no clue.
