thanks for the reply.I am a bit confused.In the first section of code I have a text widget defined like this:
Then I have a number of subroutines where $t is used again. These subroutines are bound to buttons which
are defined in the frame above with stmts like:
In the sub &tged, the get stmt should read characters within the text widget defined initially using $t.If I use
"my $t" within this sub and localise it, we wont be referring to the first $t defined outside the sub.Is that right?
These subs also use $t again and need to refer to the text widget define initially using:
I'm not sure where we should use "my", and where we should not.Turning on use strict gives no message about $t.
The sub &tged works on the first button click, and does not work therafter.The other subs are not working at all.
