Re: Led Widget

[Florent Blanchon <florent blanchon gmail com>]

Thanks.

In fact, I've found in gtkmm online doc how to do a widget.

I've done everything good but for the expose event.
Here the code :

      Glib::RefPtr<Gdk::GC> gc = Gdk::GC::create(m_refGdkWindow);


     gc->set_background(Gdk::Color("red"));
     //modify_bg(Gtk::STATE_NORMAL , Gdk::Color("red"));
     get_window()->draw_rectangle(gc, true, 0, 0, 10, 10);
     return true;

I would like to set the foreground and background color.
But the "gc->set_background(Gdk::Color("red"));" seems not to work.

I don't quite understand why....

It's probably not quite what you want, but I created a "labelled lamp" widget, based off a button, for a project I'm doing. You can find it (along with a dial/meter widget) at http://www.bdt-home.demon.co.uk/computer/gtk/gtkdial.zip and a rather crude way to use it within a GTKmm context at http://www.bdt-home.demon.co.uk/computer/gtk/FramedMeter.zip

There is a tutorial for creating a plain GTK widget somewhere (uses a basic dial as an example). Not sure about making an MM version.
