Wed Jun 24 07:47:29 1998 Tim Janik <timj@gtk.org>
* gtk/testgtk.c (create_idle_test): added a frame with radio buttons
to select the resize_mode for the idle-labels container.
* gtk/gtkframe.h:
* gtk/gtkframe.c: GtkType and macro corrections.
* gtk/gtkradiobutton.c (gtk_radio_button_set_arg): new function to
support radio grouping.
Tue Jun 23 08:01:09 1998 Tim Janik <timj@gtk.org>
* gtk/gtkcontainer.c (gtk_container_set_resize_mode): queue a resize
unconditionally if resize_mode has changed.
* gtk/gtkscrolledwindow.c (gtk_scrolled_window_init): set
GTK_RESIZE_QUEUE on the scrolled window.
(gtk_scrolled_window_construct): set GTK_RESIZE_PARENT for the vieport.
Tue Jun 23 04:20:30 1998 Tim Janik <timj@gtk.org>
* gtk/gtkcontainer.h:
* gtk/gtkcontainer.c:
(GTK_IS_RESIZE_CONTAINER): new macro to find out if
a given gtkobject is a container with resize_mode==GTK_RESIZE_PARENT.
(gtk_container_queue_resize): new function to queue a container for
a *size* reallocation (doesn't affect its position, and thus its
parent is left untouched usually).
(gtk_container_get_resize_container): new function to retrive the next
most resize container which is not itself queued for a resize.
(gtk_container_idle_sizer): new function to carefully process the
container_resize_queue since it can change during invokation of
gtk_container_check_resize().
(gtk_container_resize_children): total rework of this function to
properly handle resize containers. makes a lot of assumptions whitch
are stated in the comments.
* gtk/gtkcontainer.c:
(gtk_container_real_check_resize): only requeue ourselves if we are not
a resize container.
(gtk_container_clear_resize_widgets): care for automatic deletion of our
resize_widgets list on size_allocate through a handler connection.
* gtk/gtkwindow.c (gtk_window_shutdown): new functionm to reset the
focus and default widget of a window, so to take the burden from
gtk_widget_unparent.
* gtk/gtkviewport.c: removed gtk_viewport_check_resize, which tried
to be clever, but actually messed up the resize_children logic and
caused unneccessary allocations on its whole branch. besides this,
it messed up the display by not invoking a redraw after the allocation.
* gtk/gtktable.c (gtk_table_set_child_arg): reverted recent change, so
that it is the child again that is queued for a resize.
(gtk_table_attach): likewise.
(gtk_table_remove): likewise.
