Hello, Help Please,
I have written an initial version of a simple Cellular Automata program
using
GTKmm for the UI. Mostly the program works fine, however sometimes the
program
stops displaying the sequence of Gdk::Pixbuf that it generates. This happens
when I'm interacting with the UI of another program running on the same
machine, usually when I drag something using the cursor.
The program works by creating a std::thread and in it starting a standard
"while" loop. The code in the loop in the thread changes the data in a
Pixbuf
on each iteration. It also checks a mutex, a ConditionVariable, and a
global
variable so the loop can be interrupted from the UI (details available if
needed). After the Pixbuf data is regenerated the Pixbuf is put again
into the
Gtk::Image in the UI.
Any idea of how interacting with a separate program UI could affect this
program?
I'd be more than happy to send you the whole program if that would help.
Many Thanks in Advance,
Alex Ormond
