Description

Hi,

How can i sort the nodes in a WStandardItemModel which contains custom data, using a particular field in my custom data ?

in particular this is my case:

typedef struct

{

std::string NodeStrId;

std::string NodeStrCategoria;

std::string NodeStrIdNameCreate;

bool IsEditable;

bool IsReadable;

bool IsWritable;

}T_REC_NODE_DATA_CPP;

.....

pNodeFile->setData(boost::any(NodeData), UserRole);

I want to be able to order using the field NodeStrId.

Thanks, Francesco.

Hey Fransesco,

The easiest solution is to define a operator< in your struct, and use model->setSortRole(UserRole) to indicate that this data should be used for sorting.

Alternatively, you can reimplement WStandardItem::sortChildren() or WStandardItem::operator<
