Added "table_selection_model" argument. Removed foreach function and
2000-07-26 Christopher James Lahey <clahey@helixcode.com>
* e-table-group-container.c, e-table-group-container.h,
e-table-group-leaf.c, e-table-group-leaf.h: Added "table_selection_model"
argument. Removed foreach function and selection notification.
* e-table-group.c, e-table-group.h: Removed foreach function and
selection notification.
* e-table-header.c: Fixed header width calculation to include the
last column.
* e-table-item.c, e-table-item.h: Fixed this to use the new
selection model.
* e-table-scrolled.c, e-table-scrolled.h: Removed selection
notification.
* e-table-selection-model.c, e-table-selection-model.h: Finished
notification signals and fixed a bunch of bit manipulations.
Implemented do_something method.
* e-table.c, e-table.h: Create an ETableSelectionModel and use it
properly.
