From: Dirk Hohndel Date: Wed, 2 Nov 2011 16:10:57 +0000 (-0700) Subject: Add Info & Stats page to the notebook X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=619ab9e828d4db7b0c4089018b09892c9d04ece9;p=ext%2Fsubsurface.git Add Info & Stats page to the notebook This provides the relevant information for the currently selected dive plus a bunch of statistics over all dives in the dive_table. The visual design has lots of room for improvement - right now the different fields change size - it might be nice to have a more modern look for the entries - the O2/He field is odd - for most divers the He value will always be 0, so maybe we should only show He if there's at least one dive that uses He? Also, we simply do a comma separated list of gases for all the tanks used Signed-off-by: Dirk Hohndel --- diff --git a/Makefile b/Makefile index ab7df00..20cbf8a 100644 --- a/Makefile +++ b/Makefile @@ -81,7 +81,7 @@ LIBS = $(LIBXML2) $(LIBGTK) $(LIBDIVECOMPUTER) -lpthread OBJS = main.o dive.o profile.o info.o equipment.o divelist.o \ parse-xml.o save-xml.o libdivecomputer.o print.o uemis.o \ - gtk-gui.o $(RESFILE) + gtk-gui.o statistics.o $(RESFILE) $(NAME): $(OBJS) $(CC) $(LDFLAGS) -o $(NAME) $(OBJS) $(LIBS) @@ -136,6 +136,9 @@ info.o: info.c dive.h display.h display-gtk.h divelist.h equipment.o: equipment.c dive.h display.h divelist.h $(CC) $(CFLAGS) $(GTK2CFLAGS) $(GLIB2CFLAGS) -c equipment.c +statistics.o: statistics.c dive.h display.h divelist.h + $(CC) $(CFLAGS) $(GTK2CFLAGS) $(GLIB2CFLAGS) -c statistics.c + divelist.o: divelist.c dive.h display.h divelist.h $(CC) $(CFLAGS) $(GTK2CFLAGS) $(GLIB2CFLAGS) -c divelist.c diff --git a/display-gtk.h b/display-gtk.h index fb2b9af..3f1ff0d 100644 --- a/display-gtk.h +++ b/display-gtk.h @@ -33,6 +33,7 @@ extern GtkWidget *dive_profile_widget(void);
