Gtk-4.0 ▶ Gtk ▶ CellLayout ▶ Interface

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 property on cell to be set from that 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. In this context "attribute" and "property" are used interchangeably.

Unsets all the mappings on all renderers on cell_layout and removes all renderers from cell_layout.

Clears all existing attributes previously set with gtk_cell_layout_set_attributes().

Returns the underlying Gtk.CellArea which might be cell_layout if called on a Gtk.CellArea or might be null if no Gtk.CellArea is used by cell_layout.

Returns the cell renderers which have been added to cell_layout.

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.

Note that reusing the same cell renderer is not supported.

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.

Note that reusing the same cell renderer is not supported.

Re-inserts cell at position.

Note that cell has already to be packed into cell_layout for this to function properly.

Sets the Gtk.CellLayoutDataFunc 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 a previously set function.
