commit 2588165bfb50dcdf81e08b3e0126044ade1e98bb
Author: Tristan Van Berkom <tristan van berkom gmail com>
Date: Mon Dec 6 14:11:28 2010 +0900
Added gtk_cell_area_foreach_alloc() to further simplify GtkCellArea subclasses
gtk_cell_area_foreach_alloc() itterates over an allocated list of cells
and calls a callback with the cell's allocation until the callback returns
TRUE.
- Removed vfunc get_cell_allocation() and implemented
gtk_cell_area_get_cell_allocation() using foreach_alloc()
- Added gtk_cell_area_get_cell_at_position() using foreach_alloc()
- Removed GtkCellAreaBox ->event() implementation and implemented
mouse "click" cell activation in GtkCellArea class directly using
gtk_cell_area_get_cell_at_position().
