Sun Jan 11 00:24:21 GMT 1999 Austin Donnelly <austin@greenend.org.uk> Bit of a large checkin this - it's basically three things: 1 - GimpModules using gmodules to dynamically load and initialise modules at gimp start of day. 2 - Color selectors now register themselves with a color notebook. 3 - progress bars have been cleaned up a bit, so now have progress indictations on all transform tool and gradient fill operations. Not done bucket fill, but that seems to be the next candidate. New directories: * modules/: new directory for dynamically loadable modules. New files: * modules/.cvsignore * modules/Makefile.am * modules/colorsel_gtk.c: GTK color selector wrapped up as a color selector the gimp can use. * app/gimpprogress.[ch]: progress bars within gimp core, either as popups, or in the status bar. This is mainly code moved out of plug-in.c * app/color_notebook.[ch]: color selector notebook, implementing very similar interface to color_select.h so it can be used as a drop-in replacement for it. * libgimp/color_selector.h: API color selectors need to implement to become a page in the color_notebook. * libgimp/gimpmodule.h: API gimp modules need to implement to be initialised by gimp at start of day. Modified files: * Makefile.am: add modules/ to SUBDIRS * libgimp/Makefile.am: install gimpmodule.h and color_selector.h * app/gimprc.[ch]: recognise module-path variable. * gimprc.in: set module-path variable to something sensible (currently "${gimp_dir}/modules:${gimp_plugin_dir}/modules"). * app/Makefile.am: build color notebook and gimpprogress * app/app_procs.c: register internal GIMP color selector with color notebook. * app/asupsample.c: call progress function less frequently for better performance. * app/asupsample.h: progress_func_t typedef moved to gimpprogress.h * app/blend.c: make callbacks to a progress function * app/color_area.c: use a color notebook rather than a color selector * app/color_panel.c: ditto * app/color_select.c: export color selector interface for notebook * app/color_select.h: color_select_init() prototype * app/flip_tool.c: flip the image every time, rather than every second click. * app/interface.c: move progress bar stuff out to gimpprogress.c. Make the code actually work while we're at it. * app/interface.h: move prototypes for progress functions out to gimpprogress.h * app/plug_in.c: load and initialise modules (if possible). Move progress bar handling code out to gimpprogress.c * app/plug_in.h: keep only a gimp_progress * for each plugin, not a whole bunch of GtkWidgets. * app/scale_tool.c * app/rotate_tool.c * app/shear_tool.c * app/perspective_tool.c: progress bar during operation. De-sensitise the dialog to discourage the user from running two transforms in parallel. * app/transform_core.c: recalculate grid coords when bounding box changes. Only initialise the action area of the dialog once, to avoid multiple "ok" / "reset" buttons appearing. Undraw transform tool with correct matrix to get rid of handle remains on screen. Call a progress function as we apply the transform matrix. A few new i18n markups. Invalidate floating selection marching ants after applying matrix. * app/transform_core.h: transform_core_do() takes an optional progress callback argument (and data). * plug-ins/oilify/oilify.c: send progress bar updates after every pixel region, not only if they processed a multiple of 5 pixels (which was quite unlikely, and therefore gave a jerky progress indication).
