/**
|
|
* GtkCellAreaBox:
|
|
*
|
|
* A cell area that renders GtkCellRenderers into a row or a column
|
|
*
|
|
* The `GtkCellAreaBox` renders cell renderers into a row or a column
|
|
* depending on its `GtkOrientation`.
|
|
*
|
|
* GtkCellAreaBox uses a notion of packing. Packing
|
|
* refers to adding cell renderers with reference to a particular position
|
|
* in a `GtkCellAreaBox`. There are two reference positions: the
|
|
* start and the end of the box.
|
|
* When the `GtkCellAreaBox` is oriented in the %GTK_ORIENTATION_VERTICAL
|
|
* orientation, the start is defined as the top of the box and the end is
|
|
* defined as the bottom. In the %GTK_ORIENTATION_HORIZONTAL orientation
|
|
* start is defined as the left side and the end is defined as the right
|
|
* side.
|
|
*
|
|
* Alignments of `GtkCellRenderer`s rendered in adjacent rows can be
|
|
* configured by configuring the `GtkCellAreaBox` align child cell property
|
|
* with gtk_cell_area_cell_set_property() or by specifying the "align"
|
|
* argument to gtk_cell_area_box_pack_start() and gtk_cell_area_box_pack_end().
|
|
*
|
|
* Deprecated: 4.10: List views use widgets for displaying their
|
|
* contents
