From 48e488b596bc73000d172234f87ffd46e9f4032e Mon Sep 17 00:00:00 2001 From: Carlos Garcia Campos <carlosgc@gnome.org> Date: Sat, 27 Dec 2008 18:37:13 +0000 Subject: [PATCH] First step of the printing system rework. EvJobPrint has been replaced by 2008-12-24 Carlos Garcia Campos <carlosgc@gnome.org> * shell/Makefile.am: * shell/ev-print-operation.[ch]: * shell/ev-jobs.[ch]: (ev_job_export_init), (ev_job_export_dispose), (ev_job_export_run), (ev_job_export_class_init), (ev_job_export_new), (ev_job_export_set_page): * shell/ev-window.c: (ev_window_print_operation_done), (ev_window_print_range), (ev_window_dispose): First step of the printing system rework. EvJobPrint has been replaced by EvJobExport so that every page is scheduled to be exported in a thread instead of scheduling the whole printing process. This way the gui is responsive during printing. svn path=/trunk/; revision=3306 --- ChangeLog | 16 + shell/Makefile.am | 2 + shell/ev-jobs.c | 406 ++++---------- shell/ev-jobs.h | 72 +-- shell/ev-print-operation.c | 1043 ++++++++++++++++++++++++++++++++++++ shell/ev-print-operation.h | 59 ++ shell/ev-window.c | 328 ++---------- 7 files changed, 1277 insertions(+), 649 deletions(-) create mode 100644 shell/ev-print-operation.c create mode 100644 shell/ev-print-operation.h diff --git a/ChangeLog b/ChangeLog index e2b6718c..30685690 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,19 @@ +2008-12-24 Carlos Garcia Campos <carlosgc@gnome.org> + + * shell/Makefile.am: + * shell/ev-print-operation.[ch]: + * shell/ev-jobs.[ch]: (ev_job_export_init), + (ev_job_export_dispose), (ev_job_export_run), + (ev_job_export_class_init), (ev_job_export_new), + (ev_job_export_set_page): + * shell/ev-window.c: (ev_window_print_operation_done), + (ev_window_print_range), (ev_window_dispose): + + First step of the printing system rework.
