Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

Added some support for i18n. The support for input methods, including
Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

Tue Feb 24 22:47:01 1998 Owen Taylor <owt1@cornell.edu>
* gtk/gtktext.c: Added some support for i18n. The support
for input methods, including preedit, is there, but input
is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.

is ignored unless it comes one byte at a time, so the
CJK locales won't really work. Fixing that would require
variable-width character support in the Text widget, which
is probably the wrong approach. Eventually we'll probably
want to go to UCS-4 internally.
Also, revised key press handling, which should improve
the forwarding of non-handled keypresses to the toplevel,
and make adding selection handling easier.
* gtk/gtkentry.c: Minor changes so that C-d, etc delete
the selection if there is one.
