Wed Jan 20 11:19:00 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtklabel.c: Use floor() instead of truncating to integer values so we get translation invariance. * gtk/gtklayout.c (gtk_layout_size_allocate): Set upper and lower values for adjustments in size_allocate(). * gdk/gdkwindow.c gdk/gdk.h gdk/gdkprivate.h: New function gdk_window_set_static_gravities() to set up a window for guffaw scrolling. * gdk/gdkwindow.c (gdk_window_internal_destroy): Set flags indicating destroyed state before cleanup. * gtk/gtkprivate.h gtk/gtkwidget.c: Add a new private flag IS_OFFSCREEN. If set, this indicates to GTK+ that the widget is not to be considered viewable regardless of its map state. Queued draws on offscreen widgets are suppressed. Added new function static gtk_widget_is_offscreen() to check this flag on a widget and its ancestors. * gtk/gtklayout.[ch]: Major revisions. - Use gdk_window_set_static_gravities to set static gravity on all child windows, and thus avoid having to create a window for NO_WINDOW children. - Adjust allocations of children as we scroll them so queued draws work correctly. - Don't allocate our children directly in a put() or move(); just queue a resize() like every other widget. * gtk/testgtk.c: Make the arrows on the scrollbars work, create a larger and more demanding test.
