1999-09-27 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/gimphelp.[ch] * app/gimpui.[ch]: new files * app/interface.[ch] * app/preferences_dialog.[ch] The GIMP Help System part 1: Press "F1" in any dialog to pop up the help page for this dialog. Moved the widget constructors from preferences_dialog.[ch] and the query boxes from interface.[ch] to gimpui.[ch]. The dialog constructors take a help_func and a help_data parameter and install the "F1" accelerator which emits the new "help" signal. The "help" signal callback calls help_func(help_data) which finally has to call gimp_help() which in turn invokes the help browser. Still have to find a proper way to (1) prevent "F1" being assigned to some menu item and (2) to catch "F1" while browsing the menu trees in order to pop up the help for the selected item. * app/menus.c: a <Toolbox>/File/Help... menu item. * app/commands.[ch]: a command callback for the "Help..." menu item. * app/gimprc.[ch]: new boolean gimprc variable "use_help". * app/info_dialog.[ch]: pass a help function and data to the info dialog constructor. * app/tools.[ch]: store the tools help page names in the tool info structure. Export a special tools_help_func() which shows the help page for the active tool. * app/[all files calling a dialog constructor]: pass the dialog's help page to the constructor. Most dialogs are now created by gimp_dialog_new() which also sets up the action_area and the WM delete event callback, so I removed the resp. code from these files. Fixed some minor bugs and did some other stuff but didn't change any logic except dialog creation. * plug-ins/helpbrowser/helpbrowser.c: don't try to call a running help browser and don't install any menu path (all done in app/gimphelp.[ch] now).
