Description

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.

Details

enum GtkTreeViewColumnSizing

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.

GTK_TREE_VIEW_COLUMN_GROW_ONLY

Columns only get bigger in reaction to changes in the model

GTK_TREE_VIEW_COLUMN_AUTOSIZE

Columns resize to be the optimal size everytime the model changes.

GTK_TREE_VIEW_COLUMN_FIXED

Columns are a fixed numbers of pixels wide.

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 equivilent. This is set by calling gtk_tree_view_column_set_cell_data_func()

tree_column :

A GtkTreeViewColumn

cell :

The GtkCellRenderer that is being rendered by tree_column

tree_model :

The GtkTreeModel being rendered

iter :

A GtkTreeIter of the current row rendered

data :

user data

struct GtkTreeViewColumn

struct GtkTreeViewColumn;

gtk_tree_view_column_new ()

GtkTreeViewColumn * gtk_tree_view_column_new            (void);

Creates a new GtkTreeViewColumn.

Returns :

A newly created GtkTreeViewColumn.

gtk_tree_view_column_new_with_area ()

GtkTreeViewColumn * gtk_tree_view_column_new_with_area  (GtkCellArea *area);

Creates a new GtkTreeViewColumn using area to render its cells.

area :

the GtkCellArea that the newly created column should use to layout cells.

Returns :

A newly created GtkTreeViewColumn.

Since 3.0

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:

1
2
3
4
5
6
7
8
9
10
11
12
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);
}

title :

The title to set the header to

cell :

The GtkCellRenderer

... :

A NULL-terminated list of attributes

Returns :

A newly created GtkTreeViewColumn.

gtk_tree_view_column_pack_start ()

void                gtk_tree_view_column_pack_start     (GtkTreeViewColumn *tree_column,

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.

tree_column :

A GtkTreeViewColumn.

cell :

The GtkCellRenderer.

expand :

TRUE if cell is to be given extra space allocated to tree_column.

gtk_tree_view_column_pack_end ()

                                                         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.

tree_column :

A GtkTreeViewColumn.

cell :

The GtkCellRenderer.

expand :

TRUE if cell is to be given extra space allocated to tree_column.

                                                         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.

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.

                                                         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.

tree_column :

A GtkTreeViewColumn

resizable :

TRUE, if the column can be resized

gtk_tree_view_column_get_resizable ()

gboolean            gtk_tree_view_column_get_resizable  (GtkTreeViewColumn *tree_column);

The fixed width of the column.

gtk_tree_view_column_set_fixed_width ()

void                gtk_tree_view_column_set_fixed_width

                                                         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 minumum 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.

A GtkTreeViewColumn.

The new fixed width, in pixels, or -1.

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.

tree_column :

A GtkTreeViewColumn.

max_width :

The maximum width of the column in pixels, or -1.

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.

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().
