GTK customize UI

[chuchi]

Hi all!! I am developing an application using GTK. I need to know how to change the font size. But it is more important if you could tell me some tutorial about styles in GTK, because the GTK+ documentations does not say anything about it.

I am getting in too much trouble trying to customize my UI application.


Thank you very much!!

Here's a good place to start: http://developer.gnome.org/gtk3/3.4/GtkWidget.html#gtk-widget-override-font

You'll need to create a pango font description, the function has a link to them. You should be able to create a new one and then set the various properties for it.

Hi satsujinka! thanks for reply. I knew this reference. Do you know about some tutorial, examples??
The reference is good, but is quite difficult to understand and to put it on practice.

I don't have access to a compiler at the moment, but this should work:

#include <gtk/gtk.h>
/*modified version of the gtk example @ http://en.wikipedia.org/wiki/GTK%2B*/
int main (int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *label;
PangoFontDescription *font;

gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window), "Hello, world!");
g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
label = gtk_label_new("Hello, world!");

/* replace the string below with a string matching your desired font */
font = pango_font_description_from_string("Monospace Regular 12");

/*now override your chosen widget's font, here a label is used as an example*/
gtk_widget_override_font(label, font);

gtk_container_add(GTK_CONTAINER(window), label);
gtk_widget_show_all(window);
gtk_main();
pango_font_description_free(font);
return 0;
}
UPDATE:
This tutorial seems to have some similar information:http://zetcode.com/tutorials/gtktutorial/gtkdialogs/

don't know if this will help

if have

#include <gtk/gtk.h>and problems compiling

can try compiling like this "example.c" using gtk3 .


gcc -Wall -g `pkg-config --cflags --libs gtk+-3.0` -o example example.cthis is what some times helps in a .c file


/*modified version of the gtk example @ http://en.wikipedia.org/wiki/GTK%2B*/
/* gcc -Wall -g `pkg-config --cflags --libs gtk+-3.0` -o example example.c */
#include <gtk/gtk.h>
