From 7dae771114a7121f78f368f07f5e3adc69651c17 Mon Sep 17 00:00:00 2001 From: Federico Mena Quintero Date: Thu, 1 Oct 1998 01:32:47 +0000 Subject: Colorify the month item and prepare it for prelighting here. 1998-09-30 Federico Mena Quintero * goto.c (create_days): Colorify the month item and prepare it for prelighting here. * main.c (color_props): Changed the default colors to something not dull. * year-view.c (compute_min_size): New function to compute the minimum size of the year view properly. (year_view_size_request): Added two new fields to the year view structure that contain the minimum size. Return this in the size_request method. (year_view_new): Call compute_min_size to save the minimum size for later use. (idle_handler): Make it resize the items correctly. * gnome-month-item.c (gnome_month_item_set_arg): Reshape when necessary. This is needed becaues we now actually calculate a minimum size for the month item based on the font sizes and paddings. (check_heading_sizes): New function to calculate a minimum size based on the headings' dimensions. (check_day_sizes): New function to calculate a minimum size based on the day number labels' dimensions. (check_sizes): New function that computes a minimum size for the month item. (reshape): Now calls check_sizes() to ensure a minimum size for the month item. svn path=/trunk/; revision=419 --- calendar/year-view.c | 147 ++++++++++++++++++++++++++++++++++++++------------- 1 file changed, 110 insertions(+), 37 deletions(-) (limited to 'calendar/year-view.c') diff --git a/calendar/year-view.c b/calendar/year-view.c index 96b43c264b..93cd591292 100644 --- a/calendar/year-view.c +++ b/calendar/year-view.c @@ -18,7 +18,7 @@ #define HEAD_SPACING 4 /* Spacing between year heading and months */ -#define TITLE_SPACING 2 /* Spacing between title and calendar */ +#define TITLE_SPACING 1 /* Spacing between title and calendar */ #define SPACING 4 /* Spacing between months */ @@ -81,62 +81,71 @@ static gint idle_handler (gpointer data) { YearView *yv;
