Well, besides determining the width of the GtkTextView in
characters, I also need to determine its height in lines, or the number
of visible lines. I've tried a solution with font metrics, but the value
is wrong. The code I'm using is something like this:
PangoContext *context;
PangoFontDescription *fontdesc;
PangoFontMetrics *metrics;
int char_height;
/* Get the size of the text view */
gtk_text_view_get_visible_rect(gui->txtView, &rect);
/* Get the Pango context */
context = gtk_widget_get_pango_context(GTK_WIDGET(gui->txtView));
/* Load metrics for the font */
fontdesc = pango_context_get_font_description(context);
metrics = pango_context_get_metrics(context,
fontdesc,
NULL);
/* Determine character height */
char_height = PANGO_PIXELS(pango_font_metrics_get_ascent(metrics)
+ pango_font_metrics_get_descent(metrics));
lines = rect.height / char_height;
But the character height is returned as 29 pixels. I've counted with
xmag and the real height of a line (including possibly some inter-line
spacing not accounted for in that code) is something like 16 or 17 pixels.
