Re: Gtk::TreeView

["Vladimir Đokić" <v djokic gmail com>]

Hi all,

Here's the code snip (from various files):

int main(int argc, char* argv[])
{
    Gtk::Main kit(argc, argv);

    u1::Editor* editor = new u1::Editor();
    editor->Init();

    Gtk::Main::run(editor->GetWindow());

    delete editor;

    return 0;
}

class Editor
{
public:
    Editor()
        : mWindow(NULL)
    { /* void */ }

    ~Editor()
    { delete mWindow; }

    void Init()
    {
       ...

        Glib::RefPtr<Gnome::Glade::Xml> xml = Gnome::Glade::Xml::create("Ui/u1Editor.glade");
        xml->get_widget("u1Window", mWindow);

        ...
        Gtk::TreeView* tree_view = NULL;
        xml->get_widget("u1TreeView", tree_view);

        mTreeModel = Gtk::TreeStore::create(mTreeColumns);
        tree_view->set_model(mTreeModel);

        Gtk::TreeModel::Row row = *(mTreeModel->append());
        row[mTreeColumns.mNodeName] = "Root";

        tree_view.append_column("Nodes", mTreeColumns.mNodeName

);
    }

private:
    void OnQuit() // <-- executed from menu bar
    {
        Gtk::Main::quit();
    }

    class TreeColumns : public Gtk::TreeModel::ColumnRecord
    {

    public:

    ModelColumns()
    { add(mNodeName); }

        Gtk::TreeModelColumn<Glib::ustring> mNodeName;
    };

    TreeColumn mTreeColumns;
    Glib::RefPtr<Gtk::TreeStore> mTreeModel;
    
    Gtk::Window*   mWindow;
    
};



Hope this will make more sense,

Vladimir.

Hi all,

Unfortunately, since I'm using binary distribution of gtkmm, I'm unable to step into destruction of Gtk::Window. I've just noticed that I'm using Multithreaded Debug DLL (and don't know how gtkmm on windows was built), so I'll try changing these values... I'll post code later, when I get home (thought the code follows documentation and examples).

Thanks,

Vladimir.

Vladimir,

Could you paste the tree view code you're using.

And what is the heap message?  I don't know much about Visual Studio,
so if this is some standard error I can only assume its the equivalent
of a segfault.

Does Visual Studio have a debugger so you can see which line is
causing this error?
