change things so we focus the cell and select the row, and also dispatch
2000-06-10 Chris Toshok <toshok@helixcode.com> * e-table-item.c (eti_event): change things so we focus the cell and select the row, and also dispatch the event to that row/cell. This fixes the problem with the tree where you had to click twice to activate the tree controls. * Makefile.am (libetable_a_SOURCES): remove e-tree-gnode.* and add e-tree-simple.* (icons): add tree-expanded.xpm and tree-unexpanded.xpm * e-cell-tree.c (ect_enter_edit): defer to subcell's view. (ect_leave_edit): defer to subcell's view. (visible_depth_of_node): visual depth, taking into account that the root node of the model might not be displayed. (offset_of_node): return the offset used to shift the subcell over. (ect_draw): don't draw vertical lines if we're the leftmode node (a visual root node). also, don't shift x2 by the subcell offset, so we get ellipses like we're supposed to. (ect_event): remove GDK_BUTTON_RELEASE from the list of events that we care about. * e-tree-example-1.c: lots of changes, a more dynamic UI so we can test tree model api stuff. * e-tree-gnode.c, e-tree-gnode.c: removed files, since their guts have been rolled into e-tree-model.c * e-tree-model.c, e-tree-model.h: substantially changed. too much to really describe here. this should really be considered the first revision of these files :) * e-tree-simple.c, e-tree-simple.h: analogous to e-table-simple, a subclass that allows the use of function pointers. svn path=/trunk/; revision=3519
