From fa6e14050cf0f7341c8bf40a26c2d07cbca0d052 Mon Sep 17 00:00:00 2001 From: Miguel de Icaza Date: Tue, 19 May 1998 02:34:33 +0000 Subject: Implemented ultra-cool layout for the events that share the same time 1998-05-18 Miguel de Icaza * gncal-full-day.c (layout_children): Implemented ultra-cool layout for the events that share the same time range. Gals and guys you can now drop Outlook on the recycle bin. Which reminds me. We do not have a recycle bin. How could that happen in a project as cool as this one? Someone explain this to me. 1998-05-18 Federico Mena * gncal-full-day.c (paint_back): Eliminated unnecessary border repainting. svn path=/trunk/; revision=218 --- calendar/gncal-full-day.c | 263 ++++++++++++++++++++++++++++------------------ 1 file changed, 161 insertions(+), 102 deletions(-) (limited to 'calendar/gncal-full-day.c') diff --git a/calendar/gncal-full-day.c b/calendar/gncal-full-day.c index 1ac7613dbf..41d217cb6e 100644 --- a/calendar/gncal-full-day.c +++ b/calendar/gncal-full-day.c @@ -192,13 +192,16 @@ child_set_text_pos (Child *child) { GtkAllocation allocation; int has_focus; - + int handle_size; + has_focus = GTK_WIDGET_HAS_FOCUS (child->widget); - allocation.x = HANDLE_SIZE; - allocation.y = has_focus ?
