Re: How to bind a cairo surface to a GTKImage widget

[Luca Bacci <luca bacci982 gmail com>]

Sorry, I should have written:

Gtk::Image::set(const Cairo::RefPtr<Cairo::Surface>&)

That's the right signature...

Hi,

You can use Gtk::Image::Set(Glib::RefPtr<Cairo::Surface>) method. See here:

Hi

 

I have with me code to load an SVG (Vector) image into a cairo surface using GTKMM and CairoMM-

 

#ifdef CAIRO_HAS_SVG_SURFACE

 

    std::string filename = "image.svg";

    double width = 600;

    double height = 400;

    auto surface =

        Cairo::SvgSurface::create(filename, width, height);

 

    auto cr = Cairo::Context::create(surface);

 

    cr->save(); // save the state of the context

 

Now, I want to load this SVG image into a GTKImage area. One GTKIMage named "image_svg" is the GTKImage widget into which I want to load the SVG image.

 

How do I link the SVG image to the "image_svg" GTKImage widget?

 

Yours sincerely,

Arvind.
