GtkCellLayout is implemented by GtkCellView, GtkEntryCompletion, GtkTreeViewColumn, GtkComboBox and GtkComboBoxEntry.
GtkCellLayout is an interface to be implemented by all objects which want to provide a GtkTreeViewColumn-like API for packing cells, setting attributes and data funcs.
typedef struct { GTypeInterface g_iface; /* Virtual Table */ void (* pack_start) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gboolean expand); void (* pack_end) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gboolean expand); void (* clear) (GtkCellLayout *cell_layout); void (* add_attribute) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, const gchar *attribute, gint column); void (* set_cell_data_func) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, GtkCellLayoutDataFunc func, gpointer func_data, GDestroyNotify destroy); void (* clear_attributes) (GtkCellLayout *cell_layout, GtkCellRenderer *cell); void (* reorder) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gint position); } GtkCellLayoutIface;
void (*GtkCellLayoutDataFunc) (GtkCellLayout *cell_layout, GtkCellRenderer *cell, GtkTreeModel *tree_model, GtkTreeIter *iter, gpointer data);
A function which should set the value of cell_layout's cell renderer(s) as appropriate.
cell_layout : | a GtkCellLayout |
cell : | the cell renderer whose value is to be set |
tree_model : | the model |
iter : | a GtkTreeIter indicating the row to set the value for |
data : | user data passed to gtk_cell_layout_set_cell_data_func() |
void gtk_cell_layout_pack_start (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gboolean expand);
Packs the cell into the beginning of cell_layout. 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_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer. |
expand : | TRUE if cell is to be given extra space allocated to cell_layout. |
Since 2.4
void gtk_cell_layout_pack_end (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gboolean expand);
Adds the cell to the end of cell_layout. 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_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer. |
expand : | TRUE if cell is to be given extra space allocated to cell_layout. |
Since 2.4
void gtk_cell_layout_reorder (GtkCellLayout *cell_layout, GtkCellRenderer *cell, gint position);
Re-inserts cell at position. Note that cell has already to be packed into cell_layout for this to function properly.
cell_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer to reorder. |
position : | New position to insert cell at. |
Since 2.4
void gtk_cell_layout_clear (GtkCellLayout *cell_layout);
Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout.
cell_layout : | A GtkCellLayout. |
Since 2.4
void gtk_cell_layout_set_attributes (GtkCellLayout *cell_layout, GtkCellRenderer *cell, ...);
Sets the attributes in list as the attributes of cell_layout. The attributes should be in attribute/column order, as in gtk_cell_layout_add_attribute(). All existing attributes are removed, and replaced with the new attributes.
cell_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer. |
... : | A NULL-terminated list of attributes. |
Since 2.4
void gtk_cell_layout_add_attribute (GtkCellLayout *cell_layout, GtkCellRenderer *cell, const gchar *attribute, gint column);
Adds an attribute mapping to the list in cell_layout. The column is the column of the model to get a value from, and the attribute is the parameter on cell 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.
cell_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer. |
attribute : | An attribute on the renderer. |
column : | The column position on the model to get the attribute from. |
Since 2.4
void gtk_cell_layout_set_cell_data_func (GtkCellLayout *cell_layout, GtkCellRenderer *cell, GtkCellLayoutDataFunc func, gpointer func_data, GDestroyNotify destroy);
Sets the GtkCellLayoutDataFunc to use for cell_layout. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of cell_layout's cell renderer(s) as appropriate. func may be NULL to remove and older one.
cell_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer. |
func : | The GtkCellLayoutDataFunc to use. |
func_data : | The user data for func. |
destroy : | The destroy notification for func_data. |
Since 2.4
void gtk_cell_layout_clear_attributes (GtkCellLayout *cell_layout, GtkCellRenderer *cell);
Clears all existing attributes previously set with gtk_cell_layout_set_attributes().
cell_layout : | A GtkCellLayout. |
cell : | A GtkCellRenderer to clear the attribute mapping on. |
Since 2.4
