GtkTreeCellDataFunc ()

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 equivalent. This is set by calling gtk_tree_view_column_set_cell_data_func()

gtk_tree_view_column_new ()

GtkTreeViewColumn *
gtk_tree_view_column_new (void);

Creates a new GtkTreeViewColumn.

gtk_tree_view_column_new_with_area ()

gtk_tree_view_column_new_with_area (GtkCellArea *area);

Creates a new GtkTreeViewColumn using area to render its cells.

Since: 3.0

gtk_tree_view_column_new_with_attributes ()

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);
}

gtk_tree_view_column_pack_start ()

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

Packs the cell into the beginning 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.

gtk_tree_view_column_pack_end ()

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.

gtk_tree_view_column_clear ()

void
gtk_tree_view_column_clear (GtkTreeViewColumn *tree_column);

Unsets all the mappings on all renderers on the tree_column .

gtk_tree_view_column_add_attribute ()

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 to be set from the value. So for example if column 2 of the model contains strings, you could have the “text” attribute of a GtkCellRendererText get its values from column 2.

gtk_tree_view_column_set_attributes ()

void
gtk_tree_view_column_set_attributes (GtkTreeViewColumn *tree_column,
                                     GtkCellRenderer *cell_renderer,
                                     ...);

Sets the attributes in the list as the attributes of tree_column . The attributes should be in attribute/column order, as in gtk_tree_view_column_add_attribute(). All existing attributes are removed, and replaced with the new attributes.

gtk_tree_view_column_set_cell_data_func ()

void
gtk_tree_view_column_set_cell_data_func
                               (GtkTreeViewColumn *tree_column,
                                GtkCellRenderer *cell_renderer,
                                GtkTreeCellDataFunc func,
                                gpointer func_data,
                                GDestroyNotify destroy);

Sets the GtkTreeCellDataFunc to use for the column. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of tree_column 's cell renderer as appropriate. func may be NULL to remove an older one.

gtk_tree_view_column_clear_attributes ()

void
gtk_tree_view_column_clear_attributes (GtkTreeViewColumn *tree_column,
                                       GtkCellRenderer *cell_renderer);

Clears all existing attributes previously set with gtk_tree_view_column_set_attributes().

gtk_tree_view_column_set_spacing ()

void
gtk_tree_view_column_set_spacing (GtkTreeViewColumn *tree_column,
                                  gint spacing);

Sets the spacing field of tree_column , which is the number of pixels to place between cell renderers packed into it.

gtk_tree_view_column_get_spacing ()

gint
gtk_tree_view_column_get_spacing (GtkTreeViewColumn *tree_column);

Returns the spacing of tree_column .

gtk_tree_view_column_set_visible ()

void
gtk_tree_view_column_set_visible (GtkTreeViewColumn *tree_column,
                                  gboolean visible);

Sets the visibility of tree_column .

gtk_tree_view_column_get_visible ()

gboolean
gtk_tree_view_column_get_visible (GtkTreeViewColumn *tree_column);

Returns TRUE if tree_column is visible.

gtk_tree_view_column_set_resizable ()

void
gtk_tree_view_column_set_resizable (GtkTreeViewColumn *tree_column,
                                    gboolean resizable);

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.

gtk_tree_view_column_get_resizable ()

gboolean
gtk_tree_view_column_get_resizable (GtkTreeViewColumn *tree_column);

Returns TRUE if the tree_column can be resized by the end user.

gtk_tree_view_column_set_sizing ()

gint
gtk_tree_view_column_get_width (GtkTreeViewColumn *tree_column);

Returns the current size of tree_column in pixels.

gtk_tree_view_column_get_fixed_width ()

gint
gtk_tree_view_column_get_fixed_width (GtkTreeViewColumn *tree_column);

Gets the fixed width of the column. This may not be the actual displayed width of the column; for that, use gtk_tree_view_column_get_width().

gtk_tree_view_column_set_fixed_width ()

void
gtk_tree_view_column_set_fixed_width (GtkTreeViewColumn *tree_column,
                                      gint fixed_width);

If fixed_width is not -1, sets the fixed width of tree_column ; otherwise unsets it. The effective value of fixed_width is clamped between the minimum and maximum width of the column; however, the value stored in the “fixed-width” property is not clamped. If the column sizing is GTK_TREE_VIEW_COLUMN_GROW_ONLY or GTK_TREE_VIEW_COLUMN_AUTOSIZE, setting a fixed width overrides the automatically calculated width. Note that fixed_width is only a hint to GTK+; the width actually allocated to the column may be greater or less than requested.

Along with “expand”, the “fixed-width” property changes when the column is resized by the user.

gtk_tree_view_column_set_min_width ()

void
gtk_tree_view_column_set_min_width (GtkTreeViewColumn *tree_column,
                                    gint min_width);

                                    gint max_width);

Sets the maximum width of the tree_column . If max_width is -1, then the maximum width is unset. Note, the column can actually be wider than max width if it’s the last column in a view. In this case, the column expands to fill any extra space.

gtk_tree_view_column_get_max_width ()

gint
gtk_tree_view_column_get_max_width (GtkTreeViewColumn *tree_column);

Returns the maximum width in pixels of the tree_column , or -1 if no maximum width is set.

                                 gboolean expand);

Sets the column to take available extra space. This space is shared equally amongst all columns that have the expand set to TRUE. If no column has this option set, then the last column gets all extra space. By default, every column is created with this FALSE.

Along with “fixed-width”, the “expand” property changes when the column is resized by the user.

Since: 2.4

gtk_tree_view_column_get_expand ()

gboolean
gtk_tree_view_column_get_expand (GtkTreeViewColumn *tree_column);

gtk_tree_view_column_set_sort_indicator ()

void
gtk_tree_view_column_set_sort_indicator
                               (GtkTreeViewColumn *tree_column,
                                gboolean setting);

                                     GtkSortType order);

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_id() 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().

gtk_tree_view_column_get_sort_order ()

Sets the cell renderer based on the tree_model and iter . That is, for every attribute mapping in tree_column , it will get a value from the set column on the iter , and use that value to set the attribute on the cell renderer. This is used primarily by the GtkTreeView.

gtk_tree_view_column_cell_get_size ()

void
gtk_tree_view_column_cell_get_size (GtkTreeViewColumn *tree_column,
                                    const GdkRectangle *cell_area,
