whether the object is expandable and it isn't, make sure to send a
signal when it becomes expandable.
* e-tree-table-adapter.c: Made it so that in a number of cases
where it doesn't need to create an empty hash table node if the
current tree node has no children, it doesn't.
2001-03-18 Christopher James Lahey <clahey@ximian.com>
* e-tree-memory-callbacks.c, e-tree-memory-callbacks.h

Added has_save_id and get_save_id methods.
* e-tree-sorted.c: Proxy pre_change signal. Implemented

has_save_id then we g_strdup_printf the pointer of the base model
ETreePath as the save_id.

has_save_id, then use the results of get_save_id as the key for

node.
* e-tree.c (e_tree_set_state_object): Set the sort_info on the
ETreeSorted when you get a new sort_info.
2001-03-16 Christopher James Lahey <clahey@ximian.com>

(e_table_sorting_utils_affects_sort): Changed the signature of
this function to not take the ETableModel source since it doesn't

the get_expanded_default for this tree.
* e-tree-model.h: Cleaned up the indentation here.
* e-tree-sorted.c, e-tree-sorted.h: New class meant to be used for
sorting trees. It doesn't actually sort yet. It simply acts as
an ETreeProxy which is the hardest part of making ETreeSorted.
* e-tree.c, e-tree.h: Made this use an ETreeSorted.
2001-03-14 Christopher James Lahey <clahey@ximian.com>
* e-table-item.c, e-table-item.h, e-table-selection-model.c,
e-table-selection-model.h, e-table-sorted.c, e-table-sorted.h,
e-table-subset.c, e-table-subset.h, e-table.c, e-table.h: Switch
to handling e_table_model_rows_inserted instead of
e_table_model_row_inserted and e_table_model_rows_deleted instead

2001-03-13 Christopher James Lahey <clahey@ximian.com>
* e-table-extras.c: Added a "string-integer" comparison function
to the default %ETableExtras so you can do comparisons based on
integer value even if you using strings for the data (this lets

draw_grid off it doesn't add space for the horizontal lines, nor

has_save_id methods to %ETableModel.

(e_tree_model_node_remove): same, and use e_tree_path functions.
(e_tree_model_node_insert_before): add a loop here to figure out
the position, since it's the only place we care about the child
position.
(e_tree_model_node_sort): rework to accomodate new e_tree_path
functions, and put the e_tree_model_node_set_expanded calls in a
separate loop after all the children have been added.

tree traversal operations (get_first_child, get_last_child), as
well as a new function to traverse depth first the descendents of
a node (e_tree_model_node_traverse), much like g_node_traverse
(G_IN_ORDER). Also, ETreePath is an opaque type now, and is not a
GNode.

(etsv_add): If we are adding a lot (>ETSV_INSERT_MAX) items,
without hitting an idle loop, assume we're better off performing a
sort instead. Use another idle handler to reset the count.

2000-09-29 Not Zed <NotZed@HelixCode.com>
* e-cell-tree.c (e_cell_tree_get_node): Changed to take the source
model, not the tree model. The source model may be a subset, and
it needs to remap the rows for us.
(ect_draw):

(ect_max_width):
(ect_print): Changed callers.
* e-table-sorted-variable.c (etsv_sort_subset):

ETreePathCompareFunc.
* e-tree-model.c (e_tree_model_node_set_compare_function): new
function, used to set the comparison function for sorted nodes.
Eventually sorting entail just calling this function, with the
tree maintaining the sort.
(e_tree_model_node_sort): use a helper function
(e_tree_model_node_compare) to allow the e-tree user's comparison
function to take mode reasonable paramaters. also, fix it so the
previous expanded state is kept with the node. i can't believe i
wrote it the way it originally was. also, don't take the
comparison function here. it's set in
e_tree_model_node_set_compare_function.

2000-06-23 Chris Toshok <toshok@helixcode.com>
* e-tree-model.h, e-tree-model.c: add icon_at virtual function -
it was stupid to make the insert call take 2 pixbufs. the model

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.

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.

* e-tree-gnode.c, e-tree-gnode.h: New files. A tree model using a
GNode structure to store it's info.
* e-tree-model.c, e-tree-model.h: New files. A proxy model
sitting between a table model and the real tree model (of which
ETreeGNode is an example).
* e-cell-tree.c, e-cell-tree.h: New files. A cell renderer
capable of wrapping up a subcell and drawing the tree controls for
expanding/collapsing trees.
* tree-expanded.xpm, tree-unexpanded.xpm: New files. the standard
+ and - icons.
* e-tree-example-1.c: New file, giving a (pretty poor :) example
of using ETreeGNode.
* Makefile.am: at the tree stuff to the build, and build
tree-example-1.
* .cvsignore: ignore tree-example-1.
