Boost Lambda

[biggoron]

I can't get it to work in this case.

Code:

void TreeView::clear()
{
    using boost::lambda::_1;

    // TreeNodeChildren is an STL-like container of Gtk::TreeRow
    // const Gtk::TreeRow& is interchangable with const Gtk::TreeIter&
    // refStore->erase takes a const Gtk::TreeIter&

    Gtk::TreeNodeChildren children = scriptsRow.children();
    std::for_each(children.begin(), children.end(), refStore->erase(_1));
}

Errors:

In member function ‘void TreeView::clear()’:
error: no matching function for call to ‘Gtk::TreeStore::erase(const boost::lambda::lambda_functor<boost::lambda::placeholder<1> >&)’
note: candidates are: Gtk::TreeIter Gtk::TreeStore::erase(const Gtk::TreeIter&)
=== Build finished: 1 errors, 0 warnings ===

Thanks.

You need to use boost::bind or boost::lambda::bind there.

Code

GeSHi (cpp):
void TreeView::clear()
{
    Gtk::TreeNodeChildren children = scriptsRow.children();
    std::for_each(children.begin(), children.end(), boost::bind(&TreeView::erase,refStore, _1);
}

Thanks, that got it.
