tk_messageBox 在网格视图中显示错误，但在包中没问题

Question

I am trying to display a message box in TCL/TK and it is expected to be closed to perform any operation in parent window. When I execute the below code, the text box is going to the "disabled" state even after clearing the message box.

wm title . "Message Box Demo"

tk::text .t0

grid .t0 -column 0 -row 1 -columnspan 2

tk_messageBox -type okcancel  -message "Press Ok to confirm" \
    -title "Update V 3.6" -icon "info"

If I introduce TopLevel to include "parent' window in messageBox, it is opening a new window as top-level window and allowing to access the text box.

wm title . "Message Box Demo"

toplevel .top1
tk::text .t0

grid .t0 -column 0 -row 1 -columnspan 2

tk_messageBox -type okcancel -parent .top1 -message "Press Ok to confirm" \
    -title "Update V 3.6" -icon "info"

can someone help me to identify what is wrong here?

Answer 1

Recreated on windows. This does appear to be a bug and I have opened a ticket for it.

You can do:

 toplevel .top1
 wm withdraw .top1

to hide the .top1 window.
