Re: Line space between rows of a Gtk::TreeView - HOW?

[Iker Perez de Albeniz <ialbeniz cbt es>]

Hi,

I don t know if a have understand correctly... you want to drwa a
Gtk::HSeparator like line??


if you want to do this you have to do with a CellRenderer... adding this
lineas to the "render_vfunc"


/***************************************************************/
Glib::RefPtr<Gdk::GC> line1GC = Gdk::GC::create(window);
line1GC->set_rgb_fg_color(m_Color1);

window->draw_line(line1GC,begining_x,begining_y,end_x, end_y);

Glib::RefPtr<Gdk::GC> line2GC = Gdk::GC::create(window);
line2GC->set_rgb_fg_color(m_Color2);

window->draw_line(line2GC,0,begining_x,begining_y,end_x, end_y);
/****************************************************************/

for example in my own cellrenderer the "render_vfunc" looks like that:

/**********************************************************************/

void CellRendererComent::render_vfunc(const Glib::RefPtr<Gdk::Drawable>&
window, Gtk::Widget& widget, const Gdk::Rectangle& background_area, const
Gdk::Rectangle& cell_area, const Gdk::Rectangle& expose_area,
Gtk::CellRendererState flags)
{
	//LOG("Calling render_vfunc");
	const unsigned int cell_xpad = property_xpad();
	const unsigned int cell_ypad = property_ypad();

	int x_offset = 0, y_offset = 0, width = 0, height = 0;
	this->get_size(widget, cell_area, x_offset, y_offset, width, height);

	width -= cell_xpad * 2;
	height -= cell_ypad * 2;

	if (width <= 0 || height <= 0)
		return;

	Gtk::StateType state = Gtk::STATE_INSENSITIVE;

	if (flags & Gtk::CELL_RENDERER_SELECTED != 0)
	{
		state = (widget.has_focus()) ? Gtk::STATE_SELECTED : Gtk::STATE_ACTIVE;
	}

	

	//Cast the drawable to a Window.
	Glib::RefPtr<Gdk::Window> window_casted =
Glib::RefPtr<Gdk::Window>::cast_dynamic<>(window);
	if(window)
	{
		Gdk::Color m_Color;
		m_Color.set_red(0);
		m_Color.set_blue(65535);
		m_Color.set_green(65535);

		Gdk::Color m_Color1;
		m_Color1.set_red(4369);
		m_Color1.set_blue(4369);
		m_Color1.set_green(4369);

		Gdk::Color m_Color2;
		m_Color2.set_red(25700);
		m_Color2.set_blue(22102);
		m_Color2.set_green(23387);
		
		int rend_w, rend_h;
		
		Glib::RefPtr<Gdk::Pixbuf> image;
		const bool cheked = property_checked();
		
		if(cheked){
		image =
Gdk::Pixbuf::create_from_file("./pixmaps/machineMovement/comments_arrow.png");
		}else{
		image =
Gdk::Pixbuf::create_from_file("./pixmaps/machineMovement/comments_arrow-n.png");
		}
		
		Glib::RefPtr<Gdk::Colormap> refCmap = widget.get_default_colormap();
		refCmap->alloc_color(m_Color);
		Glib::RefPtr<Gdk::GC> refGC = Gdk::GC::create(window);
		refGC->set_foreground(m_Color);
		
		window->get_size(rend_w, rend_h);
		//window->draw_rectangle(refGC,true, , cell_area.get_y() + y_offset +
cell_ypad,image->get_width(), image->get_height());
		window->draw_pixbuf(refGC, image, 0, 0,288/*cell_area.get_x() + x_offset
+ cell_xpad*/, cell_area.get_y() + y_offset + cell_ypad - 5,
image->get_width(), image->get_height(),Gdk::RGB_DITHER_NONE, 0, 0);
		

		Glib::RefPtr<Gdk::GC> line1GC = Gdk::GC::create(window);
		line1GC->set_rgb_fg_color(m_Color1);

		window->draw_line(line1GC,0,cell_area.get_y()+26,295,cell_area.get_y()+26);

		Glib::RefPtr<Gdk::GC> line2GC = Gdk::GC::create(window);
		line2GC->set_rgb_fg_color(m_Color2);

		window->draw_line(line2GC,0,cell_area.get_y()+27,295,cell_area.get_y()+27);
		
	}
}

I hope this will help you!!
