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.
