2001-03-11 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/apptypes.h * app/gimplayerlistview.[ch]: new subclass of GimpDrawableListView (the upcoming replacement of the layers dialog). Connects to the new GimpLayer signals using the layer container as signal proxy (see below). * app/gimpcontainerview.[ch]: made "set_container" a virtual function. This is needed by the GimpLayerListView to connect/disconnect signals. Subclasses implementing this method MUST obey the following order of instructions: 1. disconnect from signals related to GimpContainerView->container 2. chain up (!!!) 3. connect to signals related to GimpContainerView->container And yes, I will add DocBook files for all those new objects :) * app/gimppreview.[ch]: made "border_color" a GimpRGB instead of guchar[3]. Added gimp_preview_set_border_color(). * app/gimpcontainergridview.c * app/gimplayerlistitem.c: use gimp_preview_set_border_color(). * app/gimpcontainerlistview.c * app/gimpdrawablelistview.c: cleanup. * app/gimpdrawablelistitem.c: we can safely asume that our parent widget is a GimpDrawableListView and use it's "reorder_drawable" function pointer (after checking that it's there). * app/gimplistitem.c: connect the correct DND type when changing the container of a list item with "reorderable" enabled. * app/gimplayer.[ch]: added accessors and "*_changed" signals for layer->mode, layer->opacity and layer->preserve_trans. * app/disp_callbacks.c: fixed a FIXME: use the correct bucket fill tool context again. * app/tools/paint_options.[ch]: paint_mode_menu_new(): added a boolean which toggles the "Behind" item on/off to the same constructor can be used for all paint mode menus. * app/tools/gimptoolinfo.c: rect. select is the standard tool again. * app/brush_select.c * app/floating_sel.c * app/gimpimage.c * app/layers_dialog.c * app/pdb/layer_cmds.c * app/tools/gimpeditselectiontool.c * tools/pdbgen/pdb/layer.pdb: use the new layer accessors and the paint_mode_menu constructor. * app/commands.c * app/gdisplay.c * app/menus.c * app/undo.c * app/tools/gimppainttool.c * app/tools/gimptool.c * app/tools/paint_options.c * app/tools/tool_manager.c: put the #warning's back inside #ifdef __GNUC__
