Hello, does anyone know how to align the baselines of
GtkLabels? Without reimplementing most of GtkLabel, if
possible.
Assume a table such as this one:
====================================================================
include <gtk/gtk.h>
int
main(int argc, char *argv[])
{
static const gchar *labels[] = {
"Tag<sub>1</sub>:", "bloody",
"Tag<sub>2</sub>:", "10<sup>6</sup>",
"Value:", "10<sup>-2</sup>",
};
GtkWidget *window, *table;
guint i;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
table = g_object_new(GTK_TYPE_TABLE,
"n-rows", G_N_ELEMENTS(labels)/2, "n-columns", 2,
"row-spacing", 2, "column-spacing", 6,
"border-width", 6,
NULL);
gtk_container_add(GTK_CONTAINER(window), table);
for (i = 0; i < G_N_ELEMENTS(labels); i++)
gtk_table_attach(GTK_TABLE(table),
g_object_new(GTK_TYPE_LABEL,
"label", labels[i], "use-markup", TRUE,
"xalign", 0.0,
NULL),
i % 2, i % 2 + 1, i/2, i/2 + 1,
GTK_FILL, GTK_FILL, 0, 0);
gtk_widget_show_all(window);
gtk_main();
return 0;
}
====================================================================
The baselines of the labels are clearly misaligned due to
the presence of subscripts and superscripts.
Pango of course can calculate the ascent, descent and
baseline position of a layout, however I cannot see how to
use them to get aligned labels (except for some ugly hacks
and implementation of a new label widget).
Insertion of some strut with the height and depth of a text
with both subscripts and superscripts to each label involved
would correct the alignment too, but I do not know how to do
this either.
