HelloWorld::HelloWorld() : m_textview() {
add(m_textview);
m_textview.show();
Glib::Thread::create(sigc::mem_fun(*this, &HelloWorld::cpp_app),
true);
}
[...]
void HelloWorld::cpp_app() {
string texttoprint = "";
Glib::RefPtr<Gtk::TextBuffer> m_refTextBuffer;
m_refTextBuffer = Gtk::TextBuffer::create();
string runit(std::string c);
texttoprint +=
"About to run a number of c++ functions\nand display the
results\n";
m_refTextBuffer->set_text(texttoprint);
m_textview.set_buffer(m_refTextBuffer);
sleep(10); // This sleep function represents any c++ function
performaing a task
I would like to clarify implementation details a bit more from this
programming attempt. Can it be that the referenced text buffer is
written in a thread-unsafe way here?
How do think about to apply improved techniques and software ingredients
like locks for memory consistency?
(Andrew Potter and Gavin Lambert suggested also an alternative program
structure. -
