Re: Storring value in treeview

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

The type of row[m_columns.m_type] is not myclass::MyType, it's Gtk::TreeValueProxy<myclass::MyType>. I'm not sure what happens when you print a TreeValueProxy<myclass::MyType> with std::cout <<. It might be its address that's printed.

Some alternatives that I believe will work:
std::cout << row.get_value(m_columns.m_type) << std::endl;
std::cout << static_cast<myclass::MyType>(row[m_columns.m_type]) << std::endl;

Hi,

Simple example:

class myclass {

enum MyType {

None = 0,

Firsttype ,

Secondtype

};

}

I have a class member that returns MyType. Let's call it get_type (). 

Some code exame:

void myfunc (sometype obj)

{

Gtk::TreeModel::Row row =*(m_refTreeView-> get_selected ());

row[m_columns.m_type] = obj.get_type ();

// checking code

std::cout << "1typ is " << obj.get_type () << std::endl;

std::cout << "2typ is " << row [m_columns.m_type]  << std::endl;

}

m_columns.m_type is MyType type.

I don't understand,  why I see different outputs. In the first case I have the correct value 1 or 2, while in thesecond one I see a random value 86363773. 

I have many columns and have no problems with them. 

Could you please clarify what I missed. Let me know if you need more information.

Thanks.
