[gtkmm] Gtk::Label font size and Pango::AttrList

["Enrico Costanza" <ec142 york ac uk>]

Dear all,

 

I would like to change the font size of a label. Looking on the documentatation the way to go seems to use Gtk::Label::set_attributes()

I have tryed so, but I get a segmentation fault.

Here is my code:

 

Gtk::Label *label = manage( new Gtk::Label("text") );

Pango::FontDescription fd;

fd.set_size(30);

Pango::Attribute attr = Pango::Attribute::create_attr_desc(fd);

Pango AttrList labelAttributes;

labelAttributes.insert( attr );

label->set_attributes( attr );

 

I get a segmentation fault from labelAttributes.insert( attr )

Can anyone suggest why?

I have also tryed to use Pango::Attribute::create_attr_size, and I had the same resutl.

 

Thank you in advance.

 

Regards,
