I tried it over two methods
first - change color on a toggled button signal:
Gdk::Color color_init; // initialization in header
file
void histtools::on_active1_toggled() // histtools is a subwindow of
Gtk::Window
{ // active1 is a pointer
to a toggle button
if (active1->get_active())
{...
color_init.set_rgb(255,0,0);
colorbutton1 -> set_color(color_init); // colorbutton is pointer to a
color button
}...
}
second - in the initialization:
Gdk::Color color_init; // initialization in header
file
Gtk::ColorButton *colorbutton1;
histtools_glade::histtools_glade() : Gtk::Window(Gtk::WINDOW_TOPLEVEL)
{
....
color_init.set_rgb(255,0,0);
colorbutton1 = Gtk::manage(new class Gtk::ColorButton(color_init));
....
}
I have only taken out related code, since my application is to big to put
all in if it not helps I could create an example case.
