22 * SECTION:adg-table-cell
23 * @Section_Id:AdgTableCell
24 * @title: AdgTableCell
25 * @short_description: A single cell of a table
27 * The #AdgTableCell is a boxed type, the basic component of an
28 * #AdgTable entity. It must be added to an #AdgTableRow that,
29 * in cascade, will be added to an #AdgTable entity.
31 * Any cell can be filled with a title and a value: the font to be
32 * used will be picked up from the #AdgTableStyle got by resolving
33 * the #AdgTable:table-dress property.
35 * The default title is placed at the upper left corner of the cell
36 * while the value is centered up to the bottom edge of the cell.
37 * Anyway the text positioning can be customized by using the
38 * adg_table_cell_set_value_pos() method.
40 * Some convenient functions to easily create title and value entities
41 * with plain text are provided: adg_table_cell_new_full(),
42 * adg_table_cell_set_text_title() and adg_table_cell_set_text_value().
43 * When using these methods keep in mind the underlying #AdgToyText
44 * entities will be displaced accordingly to the
45 * #AdgTableStyle:cell-padding value, not used when setting the
46 * entities through other APIs.
54 * An opaque structure referring to the cell of an #AdgTableRow.
55 * Any row can have an unlimited number of cells.
