Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.

Also, port to use PangoLayoutIter. (find_display_line_below): same problem as find_display_line_above. Also, port to use PangoLayoutIter.

Make parent_class static. Sun Nov 5 04:24:53 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkcellrenderertextpixbuf.c: Make parent_class static. Tue Sep 19 10:54:22 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontext*.[ch] gtk/gtkimmulticontext.[ch] gtk/gtktextlayout.[ch] gtk/gtktextview.c gtk/gtkentry.c: Add support for positioning the cursor within the preedit string. Mon Sep 18 23:56:32 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextview.c: Check for bindings after passing events to im context filter. Mon Sep 18 11:50:51 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.c (add_preedit_attrs): Handle empty attribute lists properly. Sun Sep 17 10:08:16 2000 Owen Taylor <otaylor@redhat.com> * gtk/queryimmodules.c (main): Return non-zero exit status if errors were encountered querying any modules. Sat Sep 16 14:01:52 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtk.h: include gtkmodule.h gtkoldeditable.h, don't include gtkthemes.h. * gtk/testgtk.c gtk/testtext.c: Set environment variables to point * gtk/Makefile.am: Add new .c and .h files, build gtk-query-immodules and use it to create a gtk.immodules file for use of test programs. * gtk/gtkpreview.c: remove extra blank line. Sat Sep 16 13:21:04 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimcontextsimple.c (gtk_im_context_simple_add_table): Add the ability to add extra tables beyond the default one, and also the ability to have compose sequences that are prefixes of other compose sequences. * gtk/gtkimcontextsimple.c: Export a preedit string which consists of possible candidates for keystrokes that have been entered but not yet committed. * gtk/gtkimcontext.[ch] gtk/immulticontext.[ch] gtk/gtkimcontextsimple.[ch]: add gtk_im_context_reset() * gtk/gtkmulticontext.[ch] (gtk_im_multicontext_append_menuitems): Add a function to add input-method switching menu items to a menu. * gtk/gtkimmulticontext.[ch]: Properly handly set_client_window when switching input methods. * gtk/gtkimcontextsimple.[ch]: Change the format of the compose table to allow compose tables of different lengths / sequence. Sat Sep 16 13:05:48 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkimmodule.[ch]: Support routines for loading GtkIMContext implementations dynamically at runtime. * gtk/queryimmodules.c: Program to query the available input modules and write the results into a file. * gtk/gtkrc.[ch] (gtk_rc_get_im_module_file): Add extra config options "im_module_file" (cache file for input method modules), and "im_module_path" - path to look for modules when generating cache file. This doesn't scale. Sat Sep 16 13:09:06 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkthemes.[ch] gtk/gtkmodule.[ch]: Move most of the generic code from gtkthemes into a new abstraction GtkModule which has the logic for implementing a loadable module which implements a number of GObject types. Sat Sep 16 13:07:13 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtkeditable.[ch]: Convert GtkEditable from a class into an interface * gtk/gtkoldeditable.[ch]: Move the old editable implementation into here, so legacy widgets can still rely on the implemenation. GtkOldEditable exports GtkEditable. Make selection handling code use new text conversion functions (and handle UTF-8 as a side-effect). Use GtkClipboard for CLIPBOARD. * gtk/gtktext.[ch] gtk/gtkcombo.c gtk/gtkspinbutton.c: Adopt to match above changes. * gtk/gtkentry.[ch]: Implement GtkEditable directly, avoid GtkOldEditable implementation. Restructure to reduce number of places that modify state directly. Move to GtkBindingSet. Display the preedit string. Queue recomputation of PangoLayout and scroll position to improve effiency of doing complex changes naively. Add a menu with cut/copy/paste and input method selection. Thu Sep 14 22:11:05 2000 Owen Taylor <otaylor@redhat.com> * gtk/gtktextlayout.[ch]: Add gtk_text_layout_set_preedit_string() to set preedit string and attributes; display preedit string by inserting string and attributes at cursor when creating the GtkTextLineDisplay. * gtk/gtktextlayout.c: Move all conversions between byte positions in PangoLayout and GtkTextIter into new functions line_display_iter_to_index/index_to_iter that properly handle the preedit string. * gtk/gtktextmark.[ch]: Restore gtk_text_mark_get_name, modify it to return const char * (eventually will end up as GCONST char *, most likely.) * gtk/gtktextview.[ch]: Handle the preedit string, call gtk_im_context_reset() as necessary, add a menu to switch input methods. * gtk/gtktextlayout.[ch]: Remove useless gtk_text_layout_get_log_attrs() function.
