Hi, I'm wondering what functions I should use in GTK 2.2.2 to calculate the size of some text.
I just did this using a PangoFontMetric.
Here's what I did:
PangoLayout *layout; PangoContext *context; PangoFontMetrics *metrics; gchar *text_string; gint textx, texty, char_width, string_width;
layout = gtk_widget_create_pango_layout(widget, NULL);
text_string = g_strdup_printf(some_text);
pango_layout_set_text(layout, text_string, -1);
/* want this text in the center of x-dimension and
7/8 down the y dimension of the widget */
textx = widget->allocation.width / 2;
texty = 7 * widget->allocation.height / 8;/* find out how wide the characters are to center on textx */ context = gtk_widget_get_pango_context(widget);
metrics = pango_context_get_metrics(context,
widget->style->font_desc,
pango_context_get_language(context));
char_width = pango_font_metrics_get_approximate_char_width (metrics);
string_width = strlen(text_string) * PANGO_PIXELS(char_width);
gtk_paint_layout(widget->style, widget->window,
GTK_WIDGET_STATE(widget), FALSE,
NULL, widget, "widget_name", textx - (string_width/2), texty,
layout);I don't know if this is a good way to do this or not, but it worked for me.
Cheers,
