int | 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 Gtk::CellRendererText get its values from column 2.
- Parameters:
-
cell_renderer The Gtk::CellRenderer to set attributes on. attribute An attribute on the renderer. column The column position on the model to get the attribute from.

) | const |
Obtains the width and height needed to render the column.
This is used primarily by the Gtk::TreeView.
- Parameters:
-

See also unset_cell_data_func().
- Parameters:
-
cell_renderer A Gtk::CellRenderer slot The callback slot to use. Create this with sigc::mem_fun(), or sigc::ptr_fun().
Referenced by Gtk::TreeView::append_column_numeric().
void Gtk::TreeViewColumn::set_clickable | ( | bool | clickable = true |
) |
Sets the header to be active if active is true
.
When the header is active, then it can take keyboard focus, and can be clicked.
- Parameters:
-
clickable true
if the header is active.
void Gtk::TreeViewColumn::set_expand | ( | bool | expand = true |
) |
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
.
- Parameters:
-
expand true
if the column should take available extra space,false
if not.
void Gtk::TreeViewColumn::set_fixed_width | ( | int | fixed_width | ) |
Sets the size of the column in pixels.
This is meaningful only if the sizing type is Gtk::TREE_VIEW_COLUMN_FIXED. The size of the column is clamped to the min/max width for the column. Please note that the min/max width of the column doesn't actually affect the "fixed_width" property of the widget, just the actual size when displayed.
- Parameters:
-
fixed_width The size to set tree_column to. Must be greater than 0.
void Gtk::TreeViewColumn::set_max_width | ( | int | 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.
- Parameters:
-
max_width The maximum width of the column in pixels, or -1.
void Gtk::TreeViewColumn::set_min_width | ( | int | min_width | ) |
Sets the minimum width of the tree_column.
If min_width is -1, then the minimum width is unset.
- Parameters:

- Parameters:
-
renderer The view cell renderer which will render the model column. column The model column to be renderered by this view.
void Gtk::TreeViewColumn::set_reorderable | ( | bool | reorderable = true |
) |
If reorderable is true
, then the column can be reordered by the end user dragging the header.
- Parameters:
-
reorderable true
, if the column can be reordered.
void Gtk::TreeViewColumn::set_resizable | ( | bool | resizable = true |
) |
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.
- Parameters:
-
resizable true
, if the column can be resized.
void Gtk::TreeViewColumn::set_sizing | ( | TreeViewColumnSizing | type | ) |
void Gtk::TreeViewColumn::set_sort_column | ( | int | sort_column_id | ) |
Sets the logical sort_column_id that this column sorts on when this column is selected for sorting.
Doing so makes the column header clickable.
- Parameters:
-
sort_column_id The sort_column_id of the model to sort on.
void Gtk::TreeViewColumn::set_sort_column | ( | const TreeModelColumnBase& | sort_column_id | ) |
Sets the logical sort_column_id that this column sorts on when this column is selected for sorting.
Doing so makes the column header clickable.
- Parameters:
-
sort_column_id The sort_column_id of the model to sort on.
void Gtk::TreeViewColumn::set_sort_column_id | ( | int | sort_column_id | ) |
- Deprecated:
- Use set_sort_column() instead.

- Deprecated:
- Use set_sort_column() instead.
void Gtk::TreeViewColumn::set_sort_indicator | ( | bool | setting | ) |
Call this function with a setting of true
to display an arrow in the header button indicating the column is sorted.
Call set_sort_order() to change the direction of the arrow.
- Parameters:
-
setting true
to display an indicator that the column is sorted.
void Gtk::TreeViewColumn::set_sort_order | ( | SortType | order | ) |
Changes the appearance of the sort indicator.
This <emphasis>does not</emphasis> actually sort the model. Use 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 set_sort_indicator().
- Parameters:
-
order Sort order that the sort indicator should indicate.
void Gtk::TreeViewColumn::set_spacing | ( | int | spacing | ) |
Sets the spacing field of tree_column, which is the number of pixels to place between cell renderers packed into it.
- Parameters:
-
spacing Distance between cell renderers in pixels.
void Gtk::TreeViewColumn::set_title | ( | const Glib::ustring & | title | ) |
Sets the title of the tree_column.

title The title of the tree_column.
void Gtk::TreeViewColumn::set_visible | ( | bool | visible = true |
) |
Sets the visibility of tree_column.
- Parameters:
-
visible true
if the tree_column is visible.
void Gtk::TreeViewColumn::set_widget | ( | Gtk::Widget& | widget | ) |
Sets the widget in the header to be widget.
If widget is 0

- Parameters:
-
widget A child Gtk::Widget, or 0
.
