New file. Implement a multi-state image toggle cell object.
1999-11-29 Miguel de Icaza <miguel@gnu.org> * e-cell-toggle.c, e-cell-toggle.h: New file. Implement a multi-state image toggle cell object. * e-cell-text.c (ect_leave_edit): Handle the case of us calling leave edit manually. (ect_stop_editing): Leave manually editing here. (ect_draw): Add one pixel to the border for left and right; Handle off-screen cursor (must be improved). (ect_edit_select_all): New function. (ect_event): Select all text on editing start * e-table-item.c (eti_event): Map mouse events and dispatch them. (eti_event): Add spreadsheet mode for editing; Enter editing only with visual characters; Leave editing mode when a different row has been selected. (eti_get_height): Fix the computation for this; Fix logic for the length_threshold. (eti_draw): Add borders on all sides of the box; Only draw focus if the cell is not being edited. svn path=/trunk/; revision=1445
