Subject:
Can you help me understand the scope problem that occurs at line 18 in my
example below?
I initially set the main window icon to yicon at line 9 which works
correctly.
When I try to set the main window icon to xicon at line 19 after clicking
the button,
I get “x.rbw:19: [BUG] Segmentation fault”.
I’m sure this is a misunderstanding on my part as to the scope of
theMainWindow.
