hmm... how ? :)
How do I fix this, how do I realize window.
I really need some example code to get this.. I'm still learning gtkmm.

you can't do this until the widget (main window) has been
realized. until that time, its just a data structure in your
program -
the X server doesn't know anything about it and no window actually
exists.
add a handler for the realize event, and do this there.

Add a function to your derived class called "Sysinfo::on_realize". In
that function make the calls you were trying to make in the constructor, ala
void Sysinfo::on_realize(void)
{
Gdk::Geometry geometry;
geometry.max_height = 800;
geometry.max_width = 600;
set_geometry_hints(this->gobj(), geometry, Gdk::HINT_MAX_SIZE);
}
Then, in your constructor itself include the following line:
signal_realize().connect(sigc::mem_fun(*this, &Sysinfo::on_realize));
Thus your geometry settings function will be called *after* the window
is realized thereby allowing the gobj() call to proceed normally.
Sincerely,
