*** Please type your report below this line ***
If your keymap is designed for keys that are not displayed in the piano
keyboard, pressing the corresponding keys of your computer keyboard will
raise an error with the key note number. Moreover the same error keeps
raising afterwards for any other key pressed because the unexpected key note
number stays in the key stack. Error message looks like this:
----------------------------------------------------
can't read "keyitem(36)": no such element in array
can't read "keyitem(36)": no such element in array
while executing
"$keywin itemconfigure $keyitem($key) -fill blue"
(procedure "KeyStart" line 8)
invoked from within
[…]
----------------------------------------------------
To get this message you may use the french layout on a 3 octaves piano:
$ vkeybd --keymap /usr/share/vkeybd/vkeybdmap-french
Then press the “!” key.
Using a “catch” instruction in both KeyStart and KeyStop procedures of the
file “/usr/share/vkeybd/vkeybd.tcl” make it possible to avoid error raising
whatever the key pressed and the piano octaves displayed. Here is the small
patch:
