2001-02-13 Michael Natterer <mitch@gimp.org> * app/gradient_editor.[ch] * app/gradient_select.[ch]: use GimpContainerListView instead of cooking an own list. * app/gimpgradient.[ch]: removed the GdkPixmap from the gradient. * app/gimpcontainerlistview.c: connect the viewable's "name_changed" signal to the label. * app/gimpmarshal.[ch] * app/gimppreview.[ch]: new virtual function "get_size", * app/gimpgradientpreview.c: implement "get_size" and return a 3:1 aspect ratio. * app/gradients.c * app/palette_select.[ch] * app/palettes.c: removed the dialog freeze/thaw functions. * app/brush_select.c * app/pattern_select.c * app/plug_in.c: stuff.
