19 * SECTION:ctkcelllayout
20 * @Short_Description: An interface for packing cells
21 * @Title: CtkCellLayout
22 *
23 * #CtkCellLayout is an interface to be implemented by all objects which
24 * want to provide a #CtkTreeViewColumn like API for packing cells,
25 * setting attributes and data funcs.
26 *
27 * One of the notable features provided by implementations of
28 * CtkCellLayout are attributes. Attributes let you set the properties
29 * in flexible ways. They can just be set to constant values like regular
30 * properties. But they can also be mapped to a column of the underlying
31 * tree model with ctk_cell_layout_set_attributes(), which means that the value
32 * of the attribute can change from cell to cell as they are rendered by
33 * the cell renderer. Finally, it is possible to specify a function with
34 * ctk_cell_layout_set_cell_data_func() that is called to determine the
35 * value of the attribute for each cell that is rendered.
36 *
37 * # CtkCellLayouts as CtkBuildable
38 *
39 * Implementations of CtkCellLayout which also implement the CtkBuildable
40 * interface (#CtkCellView, #CtkIconView, #CtkComboBox,
41 * #CtkEntryCompletion, #CtkTreeViewColumn) accept CtkCellRenderer objects
42 * as <child> elements in UI definitions. They support a custom <attributes>
43 * element for their children, which can contain multiple <attribute>
44 * elements. Each <attribute> element has a name attribute which specifies
45 * a property of the cell renderer; the content of the element is the
46 * attribute value.
47 *
48 * This is an example of a UI definition fragment specifying attributes:
49 * |[
50 * <object class="CtkCellView">
51 * <child>
52 * <object class="CtkCellRendererText"/>
53 * <attributes>
54 * <attribute name="text">0</attribute>
55 * </attributes>
56 * </child>"
57 * </object>
58 * ]|
59 *
60 * Furthermore for implementations of CtkCellLayout that use a #CtkCellArea
61 * to lay out cells (all CtkCellLayouts in CTK+ use a CtkCellArea)
62 * [cell properties][cell-properties] can also be defined in the format by
63 * specifying the custom <cell-packing> attribute which can contain multiple
64 * <property> elements defined in the normal way.
65 *
66 * Here is a UI definition fragment specifying cell properties:
67 *
68 * |[
69 * <object class="CtkTreeViewColumn">
70 * <child>
71 * <object class="CtkCellRendererText"/>
72 * <cell-packing>
73 * <property name="align">True</property>
74 * <property name="expand">False</property>
75 * </cell-packing>
76 * </child>"
77 * </object>
78 * ]|
79 *
80 * # Subclassing CtkCellLayout implementations
81 *
82 * When subclassing a widget that implements #CtkCellLayout like
83 * #CtkIconView or #CtkComboBox, there are some considerations related
84 * to the fact that these widgets internally use a #CtkCellArea.
85 * The cell area is exposed as a construct-only property by these
86 * widgets. This means that it is possible to e.g. do
87 *
88 * |[<!-- language="C" -->
89 * combo = g_object_new (CTK_TYPE_COMBO_BOX, "cell-area", my_cell_area, NULL);
90 * ]|
91 *
92 * to use a custom cell area with a combo box. But construct properties
93 * are only initialized after instance init()
94 * functions have run, which means that using functions which rely on
95 * the existence of the cell area in your subclass’ init() function will
96 * cause the default cell area to be instantiated. In this case, a provided
97 * construct property value will be ignored (with a warning, to alert
98 * you to the problem).
99 *
100 * |[<!-- language="C" -->
101 * static void
102 * my_combo_box_init (MyComboBox *b)
103 * {
104 * CtkCellRenderer *cell;
105 *
106 * cell = ctk_cell_renderer_pixbuf_new ();
107 * // The following call causes the default cell area for combo boxes,
108 * // a CtkCellAreaBox, to be instantiated
109 * ctk_cell_layout_pack_start (CTK_CELL_LAYOUT (b), cell, FALSE);
110 * ...
111 * }
112 *
113 * CtkWidget *
114 * my_combo_box_new (CtkCellArea *area)
115 * {
116 * // This call is going to cause a warning about area being ignored
117 * return g_object_new (MY_TYPE_COMBO_BOX, "cell-area", area, NULL);
118 * }
119 * ]|
120 *
121 * If supporting alternative cell areas with your derived widget is
122 * not important, then this does not have to concern you. If you want
123 * to support alternative cell areas, you can do so by moving the
124 * problematic calls out of init() and into a constructor()
125 * for your class.
