2003-03-01 Michael Natterer <mitch@gimp.org> * app/core/gimpbuffer.c: don't scale the preview up if the buffer is too small. * app/core/gimppattern.c: don't add a white border around the preview if the pattern is too small. * app/widgets/gimppreviewrenderer.[ch]: new object. A buffer that updates itself on GimpViewable changes and can render itself to any widget. Basically GimpPreview reduced to the render and draw code. * app/widgets/gimppreview.[ch]: removed all rendering and drawing code and keep a GimpPreviewRenderer instance. Connect to its "update" signal for queuing draws on the preview. * app/widgets/gimpcellrendererviewable.[ch] * app/widgets/gimpcontainertreeview.c: same here: removed rendering and drawing code and keep GimpPreviewRenderers in the list store. Delays preview creation for GtkTreeViews until the buffer is really needed for drawing and adds idle preview updating on viewable changes. * app/widgets/gimppreview-utils.[ch] * app/widgets/gimpbrushpreview.[ch] * app/widgets/gimpbufferpreview.[ch] * app/widgets/gimpdrawablepreview.[ch] * app/widgets/gimpimagepreview.[ch]: removed... * app/widgets/gimppreviewrenderer-utils.[ch] * app/widgets/gimppreviewrendererbrush.[ch] * app/widgets/gimppreviewrendererdrawable.[ch] * app/widgets/gimppreviewrendererimage.[ch]: ...and converted to GimpPreviewRenderer subclasses. * app/display/gimpnavigationview.c * app/gui/palette-import-dialog.c * app/widgets/Makefile.am * app/widgets/widgets-enums.h * app/widgets/widgets-types.h * app/widgets/gimpchannellistview.c * app/widgets/gimpcomponentlistitem.c * app/widgets/gimpcontainergridview.c * app/widgets/gimpcontainermenuimpl.c * app/widgets/gimplayerlistitem.c * app/widgets/gimplistitem.c * app/widgets/gimpnavigationpreview.[ch] * app/widgets/gimpselectioneditor.c * app/widgets/gimpvectorslistview.c: changed accordingly.
