Struct gtk4::CellAreaContext
source · #[repr(transparent)]pub struct CellAreaContext { /* private fields */ }Expand description
Stores geometrical information for a series of rows in a GtkCellArea
The CellAreaContext object is created by a given CellArea
implementation via its GtkCellAreaClass.create_context() virtual
method and is used to store cell sizes and alignments for a series of
TreeModel rows that are requested and rendered in the same context.
CellLayout widgets can create any number of contexts in which to
request and render groups of data rows. However, it’s important that the
same context which was used to request sizes for a given TreeModel
row also be used for the same row when calling other CellArea APIs
such as gtk_cell_area_render() and gtk_cell_area_event().
