This were moved to widgets/e-text/ a while ago but never removed. They
2000-02-24 Christopher James Lahey <clahey@helixcode.com> * widgets/e-text.c, widgets/e-text.h, e-text-event-processor.c, e-text-event-processor.h, e-text-event-processor-emacs-like.c, e-text-event-processor-emacs-like.h, e-text-event-processor-types.h: This were moved to widgets/e-text/ a while ago but never removed. They have now been removed. * widgets/e-text/e-text.c, widgets/e-text/e-text.h: Removed some warnings from this file. Made tooltips disappear when you're finished with them. * widgets/e-minicard/test-reflow.c, widgets/e-minicard/test-minicard.c, widgets/e-minicard/test-minicard-label.c: Commented out unused about_callback functions. * widgets/e-minicard/e-reflow.c: Made e-reflow pass an EFocus to its e-minicard children. * widgets/e-minicard/e-minicard.c: Made e-minicard take and return an EFocus for its "has_focus" argument. This makes shift-tab work properly. * widgets/e-minicard/e-minicard-label.c: Made e-minicard-label take and return an EFocus for its "has_focus" argument. Made the font that e-minicard-label uses only be allocated once. * e-util/e-canvas-utils.h: Fixed the comment at the top and added #ifndef __E_CANVAS_UTILS__. * e-util/Makefile.am: Added e-xml-utils.c and e-xml-utils.h. * e-util/e-xml-utils.h, e-util/e-xml-utils.c: Added files for some xml utilities. * e-util/e-util.h: Added type EFocus which describes which direction the focus will be coming from. in mail: 2000-02-24 Christopher James Lahey <clahey@helixcode.com> * message-list.c: Changed this to not use the "x" and "y" arguments to e-table-item. in widgets/e-table: 2000-02-24 Christopher James Lahey <clahey@helixcode.com> * e-table-subset-variable.c, e-table-subset-variable.h: A new model which is a subset, but you can add and remove rows. * test-table.c: Added a thaw method for use with the e-table-subset (emits model_changed.) Adapted to the changes to e_table_item. Properly parse headers. Adapted to the changes to e_table, including creating example xml spec data. * test-cols.c, test-check.c: Added a thaw method for use with the e-table-subset (emits model_changed.) Adapted to the changes to e_table_item. * e-table.c, e-table.h: Reworked e-table to use the ETable grouping system. The only difference for the interface is that instead of passing in a column_spec and a grouping_spec, you pass in a single string that is an xml format that includes both pieces of information. * e-table-subset.h: Added rules for emacs to do correct indentation. * e-table-subset.c: Implemented freezing. No signals are emitted while frozen and "model_changed" is emitted when thawed. * e-table-sorted.h: ETableSortedClass has ETableSubset as its parent object instead of ETableSubsetClass. Fixed this. * e-table-simple.c, e-table-simple.h: Implemented the thaw method. Use of simple now requires an extra argument (the thaw method.) * e-table-model.h, e-table-model.c: Added e_table_model_freeze and e_table_model_thaw. * e-table-item.h, e-table-item.c: Reworked this a bit to make it provide some things the new group system needed and to make inter-item keyboard focus work. Changed the external interface only in the list of arguments it recognizes and signals it emits. Instead of "x" and "y", you have to use e_canvas_item_move_absolute and instead of emitting a "height_changed" signal, it emits a "resize" signal. There's new "has_focus", "width", and "height" arguments and a function to get the currently focused column. * e-table-header-item.c: Got rid of some warnings here. Changed the * e-table-group-leaf.h, e-table-group-leaf.c, e-table-group-container.h, e-table-group-container.c: New types to make e_table_group work properly. * e-table-group.h, e-table-group.c: Completely reworked e-table grouping. e-table-group now uses a hierarchical structure. * e-cell.h: Added e_cell_print. This doesn't work yet. * e-cell.c: Made e_cell_realize exist. (It was improperly named e_cell_view_realize in the .c.) * e-cell-text.c: Made the blinking cursor disappear properly. * check-filled.xpm, check-empty.xpm: Made these const char *[] instead of char *[] to avoid compiler warnings. * Makefile.am: Added e-table-group-container.c, e-table-group-container.h, e-table-group-leaf.c, e-table-group-leaf.h, e-table-subset-variable.c, e-table-subset-variable.h. svn path=/trunk/; revision=1915
