 |
|
Hi,
I would like to get all the elements in a treeview with its model liststore and I see I have to use GtkTreeModelForeachFunc but I have no idea on using it. Some help would be great.
Thanks in advance.

I have dealed with this with iterNext method, however I really would like to understand how GtkTreeModelForeachFunc works.

You would use it like this:
| Code: | myModel.foreac(&foreachNodeFunc, null);
static extern(C) bool foreachNodeFunc(GtkTreeModel* model, GtkTreePath* path, GtkTreeIter* iter, void* data)
{
TreeModel treemodel = new TreeModel(model);
TreePath treepath = new TreePath(path);
TreeIter treeIter = new TreeIter(iter);
//Do something with the model/iter
} |

| That is a GtkTreeModelForeachFunc But i have to give it a name in this case foreachNodeFunc since it's called for each node, or did you mean something else? |
