Hi,
I'm sure this question has been asked at least a million times but I
couldn't deduce the solution to it from any of the documents I've found.
I have an iconview which is populated with hundreds of thumbnails which
takes a lot of time so I wanted to do it in a separate thread. However,
the iconview ends up with one element and segfaults if I click anywhere
outside of that one element.
I can access the elements of the treemodel just fine even while the
populate thread is doing its job.
Are there any docs on doing something similar? Or perhaps a gtkmm app
that does something like that?
In the constructor of the widget holding the iconview I do the following:
Glib::Thread* const thread = Glib::Thread::create(
sigc::mem_fun(*this,&CPrintPreviewWidget::populate_iconview),
false);
and populate_iconview looks like so:
void CPrintPreviewWidget::populate_iconview(void)
{
std::list<Glib::ustring>::iterator f_iterator =
image_filelist.begin();
std::list<Glib::ustring>::iterator f_end = image_filelist.end();
Gtk::TreeModel::iterator iter;
Gtk::TreeModel::Row row;
while( f_iterator != f_end )
{
iter = refImageList->append();
row = *iter;
row[ ImageListColumns.filenames_column ] =
Glib::path_get_basename( *f_iterator );
row[ ImageListColumns.thumbnails_column ] =
Gdk::Pixbuf::create_from_file( *f_iterator,
72,
72 );
std::cout << "populating: " << *f_iterator << std::endl;
f_iterator++;
}
}
