Re: can't change color of label

[oded <o sadglad com>]

Ok, made a mistake in my post:

If I initilize the color like this:
Gdk::Color* color = new Gdk::Color("green");
Then it does it work, contrary to what I said.

But If I use this:
Gdk::Color* color = new Gdk::Color();
color->set_rgb(0,220,0);

then the label will stay black.
And adding these lines to allocate the color does not help.
Glib::RefPtr<Gdk::Colormap> colorMap=Gdk::Colormap::get_system();
colorMap->alloc_color(*color, true, true);

Thanks,

Oded.
