The GtkTreeViewColumn object represents a visible column in a GtkTreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.
Please refer to the tree widget conceptual overview for an overview of all the objects and data types related to the tree widget and how they work together.
typedef enum { GTK_TREE_VIEW_COLUMN_GROW_ONLY, GTK_TREE_VIEW_COLUMN_AUTOSIZE, GTK_TREE_VIEW_COLUMN_FIXED } GtkTreeViewColumnSizing;
The sizing method the column uses to determine its width. Please note
that GTK_TREE_VIEW_COLUMN_AUTOSIZE
are inefficient for large views, and
can make columns appear choppy.
void (*GtkTreeCellDataFunc) (GtkTreeViewColumn *tree_column, GtkCellRenderer *cell, GtkTreeModel *tree_model, GtkTreeIter *iter, gpointer data);
A function to set the properties of a cell instead of just using the
straight mapping between the cell and the model. This is useful for
customizing the cell renderer. For example, a function might get an
integer from the tree_model
, and render it to the "text" attribute of
"cell" by converting it to its written equivilent. This is set by
calling gtk_tree_view_column_set_cell_data_func()
tree_column : |
A GtkTreeColumn |
cell : |
The GtkCellRenderer that is being rendered by tree_column
|
tree_model : |
The GtkTreeModel being rendered |
iter : |

data : |
user data |
GtkTreeViewColumn* gtk_tree_view_column_new (void);
Creates a new GtkTreeViewColumn.
Returns : | A newly created GtkTreeViewColumn. |
GtkTreeViewColumn* gtk_tree_view_column_new_with_attributes (const gchar *title, GtkCellRenderer *cell, ...);
Creates a new GtkTreeViewColumn with a number of default values. This is
equivalent to calling gtk_tree_view_column_set_title()
,
gtk_tree_view_column_pack_start()
, and
gtk_tree_view_column_set_attributes()
on the newly created GtkTreeViewColumn.
Here's a simple example:
enum { TEXT_COLUMN, COLOR_COLUMN, N_COLUMNS }; ... { GtkTreeViewColumn *column; GtkCellRenderer *renderer = gtk_cell_renderer_text_new (); column = gtk_tree_view_column_new_with_attributes ("Title", renderer, "text", TEXT_COLUMN, "foreground", COLOR_COLUMN, NULL); }

void gtk_tree_view_column_pack_start (GtkTreeViewColumn *tree_column, GtkCellRenderer *cell, gboolean expand);
Packs the cell

is allocated no more space than it needs. Any unused space is divided
evenly between cells for which expand
is TRUE
.
tree_column : |
A GtkTreeViewColumn. |
cell : |
The GtkCellRenderer. |
expand : |
TRUE if cell is to be given extra space allocated to tree_column .
|
void gtk_tree_view_column_pack_end (GtkTreeViewColumn *tree_column, GtkCellRenderer *cell, gboolean expand);
Adds the cell
to end of the column. If expand
is FALSE
, then the cell
is allocated no more space than it needs. Any unused space is divided
evenly between cells for which expand
is TRUE
.

cell : |
The GtkCellRenderer. |
expand : |

void gtk_tree_view_column_add_attribute (GtkTreeViewColumn *tree_column, GtkCellRenderer *cell_renderer, const gchar *attribute, gint column);
Adds an attribute mapping to the list in tree_column
. The column
is the
column of the model to get a value from, and the attribute
is the
parameter on cell_renderer

if column 2 of the model contains strings, you could have the
"text" attribute of a GtkCellRendererText get its values from
column 2.

cell_renderer : |
the GtkCellRenderer to set attributes on |

gtk_tree_view_column_add_attribute()
. All existing attributes
are removed, and replaced with the new attributes.
tree_column : |
A GtkTreeViewColumn. |
cell_renderer : |
the GtkCellRenderer we're setting the attributes of |

older one.

If resizable
is TRUE
, then the user can explicitly resize the column by
grabbing the outer edge of the column button. If resizable is TRUE
and
sizing mode of the column is GTK_TREE_VIEW_COLUMN_AUTOSIZE, then the sizing
mode is changed to GTK_TREE_VIEW_COLUMN_GROW_ONLY.

|
void gtk_tree_view_column_set_sort_indicator (GtkTreeViewColumn *tree_column, gboolean setting);
Call this function with a setting
of TRUE
to display an arrow in
the header button indicating the column is sorted. Call

Changes the appearance of the sort indicator.
This does not actually sort the model. Use
gtk_tree_view_column_set_sort_column_id()
if you want automatic sorting
support. This function is primarily for custom sorting behavior, and should
be used in conjunction with gtk_tree_sortable_set_sort_column()
to do
that. For custom models, the mechanism will vary.
The sort indicator changes direction to indicate normal sort or reverse sort.
Note that you must have the sort indicator enabled to see anything when
calling this function; see gtk_tree_view_column_set_sort_indicator()
.
