Re: Custom CellRendererText

[Iker Perez de Albeniz <ialbeniz cbt es>]

i have tried to do this:


///////////////////////////////////////////////////
const Glib::ustring title_text = property_text();

		Glib::RefPtr<Pango::Layout> title;
		Cairo::RefPtr<Cairo::Context> context; 
		
		context = window->create_cairo_context();
		
		context->set_font_size(14);

		title->create(context);
		title->set_text(title_text);
		
		//widget.get_window()->dra
		window->draw_layout(refGC, 1, cell_area.get_y() + y_offset + cell_ypad,
title);


////////////////////////////////////////////////////////

Compiles, but when i run on windows crashes..


any other idea or method?

thanks..
