Description

Functions

e_tree_construct ()

gboolean
e_tree_construct (ETree *tree,
                  ETreeModel *etm,
                  ETableExtras *ete,
                  ETableSpecification *specification);

This is the internal implementation of e_tree_new() for use by subclasses or language bindings. See e_tree_new() for details.

Parameters

tree

The newly created ETree object.

  

etm

The model for this table.

  

ete

An optional ETableExtras. (NULL is valid.)

  

specification

an ETableSpecification

  

Returns

TRUE on success, FALSE if an error occurred

e_tree_new ()

GtkWidget *
e_tree_new (ETreeModel *etm,
            ETableExtras *ete,
            ETableSpecification *specification);

This function creates an ETree from the given parameters. The ETreeModel is a tree model to be represented. The ETableExtras is an optional set of pixbufs, cells, and sorting functions to be used when interpreting the spec. If you pass in NULL it uses the default ETableExtras. (See e_table_extras_new()).

specification is the specification of the set of viewable columns and the default sorting state and such. state is an optional string specifying the current sorting state and such.
