Calculate height including if clip_height is set to -1.
2000-06-26 Christopher James Lahey <clahey@helixcode.com> * widgets/e-text/e-text.c: Calculate height including if clip_height is set to -1. From addressbook/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * contact-editor/e-contact-editor-categories.c, addressbook/gui/component/e-cardlist-model.c: Added value_to_string handlers. * demo/addressbook-widget.c, demo/demo.c: Removed usage of "x" and "y" arguments. * addressbook/gui/component/addressbook.c: Activated Click To Add and set the click to add message. * addressbook/gui/component/e-addressbook-model.c: Added value_to_string and append_row handlers. * addressbook/gui/component/e-select-names.c: Added a column. From calendar/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * gui/calendar-model.c: Added an #ifdefed value_to_string handler assignment. From camel/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * providers/mbox/camel-mbox-summary.c: Added debugging information. From composer/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * Makefile.am: Added e-msg-composer-select-file.h for make distcheck. From e-util/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * Makefile.am: Added e-canvas-vbox.c and e-canvas-vbox.h. * e-canvas-vbox.c, e-canvas-vbox.h: New canvas object to act like a vbox using the reflow system. From mail/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * message-list.c: Added a value_to_string handler. From shell/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * glade/Makefile.am: Added EXTRA_DIST for make distcheck. From widgets/e-table/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * Makefile.am: Added e-table-click-to-add.c, e-table-click-to-add.h, e-table-one.c, and e-table-one.h. * e-table-click-to-add.c, e-table-click-to-add.h: A new canvas item that represents a single row that sometimes exists. It's for adding new rows to your table. * e-table-example-1.c, e-table-example-2.c, e-table-size-test.c, test-check.c, test-cols.c, test-table.c: Added value_to_string handlers. * e-table-group-container.c: Use value_to_string to make grouping not crash for non string columns. Made some changes to work properly in an ECanvasVbox. * e-table-group-leaf.c, e-table-item.c: Made some changes to work properly in an ECanvasVbox. * e-table-model.c, e-table-model.h: Added append_row and value_to_string methods. * e-table-one.c, e-table-one.h: Given a source ETableModel, this provides a single row model that uses the initialize_value, duplicate_value, free_value, and value_is_empty methods of the original source to implement set_value and value_at (and proxies most of the other methods.) This is used for ETableClickToAdd. * e-table-simple.c, e-table-simple.h: Added append_row and value_to_string handlers. append_row uses a GtkArg instead of a parameter to e_table_simple_new. * e-table-subset.c: Added append_row and value_to_string handlers. * e-table.c, e-table.h: Use a vbox containing an ETableClickToAdd and an ETableItem instead of an ETableItem directly. Only show the ETableClickToAdd if the top level of the xml SPEC has the attribute click-to-add set to some non-zero integer. (click-to-add="1"). Add a "click_to_add_message" argument. * e-tree-model.c: Add a commented out value_to_string handler. From widgets/meeting-time-sel/ChangeLog: 2000-06-26 Christopher James Lahey <clahey@helixcode.com> * Makefile.am: Added the include path to top_srcdir. svn path=/trunk/; revision=3744
