I think this will work:
void MyOptionGroup::add_entry(const Glib::OptionEntry& entry,
Gdk::Rectangle& arg) {
Glib::OptionGroup::add_entry(entry, sigc::bind(sigc::mem_fun(*this,
&MyOptionGroup::on_option_arg_rectangle), sigc::ref(arg)));
}
bool MyOptionGroup::on_option_arg_rectangle(const Glib::ustring&
option_name,
const Glib::ustring& value, bool has_value, Gdk::Rectangle& arg)
{
bool success = true;
// parse value to Gdk::Rectangle rect(0, 0, 600, 400);
// How I can set MyOptionGroup->m_arg_box ?
arg = rect;
return success;
}
There are some restrictions on how you can use references with
sigc::bind(). If you can't get it to work, try pointers instead:
void MyOptionGroup::add_entry(const Glib::OptionEntry& entry,
Gdk::Rectangle* arg) {
Glib::OptionGroup::add_entry(entry, sigc::bind(sigc::mem_fun(*this,
&MyOptionGroup::on_option_arg_rectangle), arg));
}
bool MyOptionGroup::on_option_arg_rectangle(const Glib::ustring&
option_name,
const Glib::ustring& value, bool has_value, Gdk::Rectangle* arg)
{
bool success = true;
// parse value to Gdk::Rectangle rect(0, 0, 600, 400);
// How I can set MyOptionGroup->m_arg_box ?
*arg = rect;
return success;
}

Thanks for you reply. Excuse me, I was not specific enough.
My problem is about store the parse result in MyOptionGroup object.
Yes:) MyOptionGroup::m_arg_box is a Gdk::Rectangle.
What bothers me with the example you showed me is that I need to
create a new function for each options of type Gdk::Rectangle. I wish
I do like add_entry(..., bool & arg), ..., add_entry (..., int &
arg)functions : The value of the option is parsed and assigned to my
object MyObjectGroup on the fly.
My command is:
$] prog --box-in="0 0300400" --box-out = "0 0150200"
Simply put, I'd avoid making comparisons with the names of options. So no:
if (option_name = "-o" && option_name =! "--box-out")
I looked at the source code of Glib :: OptionGroup and I came to this
code below:
void OptionGroup :: add_entry (const Glib::OptionEntry & entry,
Gdk::Rectangle & arg)
{
SlotOptionArgString slot = sigc :: mem_fun (* this, &
OptionGroup::on_option_arg_rectangle);
Glib::OptionGroup add_entry (entry, slot);
}
OptionGroup on_option_arg_rectangle :: bool (const Glib::ustring &
option_name, const Glib::ustring & value, bool has_value)
{
bool success = true;
OptionGroup type_map_entries::const_iterator iterFind map_entries_.end
= ();
if (option_name [1] == '-')
{
const Glib::ustring long_option_name = Glib::ustring
(option_name.c_str () +2);
iterFind map_entries_.find = (long_option_name);
Glib::OptionGroup CppOptionEntry iterFind = entry-> second;
Gdk::Rectangle * arg = static_cast <Gdk::Rectangle*> (entry.cpparg_);
arg-> set_x (100);// <-- SegFault
}
return success;
}
In this way, I can use this code for each option Rectangle kind.
Unfortunately I have a segfault on arg->set_x (100);
I got the wrong way.
Do you know how I need to do to achieve this ?
PS : If I'm misunderstanding do not hesitate to tell me

Perhaps the glibmm example program at
https://git.gnome.org/browse/glibmm/tree/examples/options/main.cc
can help you.
MyOptionGroup::add_entry() is unnecessary. You can call
Glib::OptionGroup::add_entry() directly. Or, if you prefer to keep
MyOptionGroup::add_entry(), the argument Gdk::Rectangle& arg is
unnecessary. You don't use it, anyway.
I don't see any problem in
MyOptionGroup::on_option_arg_rectangle(). I suppose
MyOptionGroup::m_arg_box is a Gdk::Rectangle. If rect is a local
Gdk::Rectangle in MyOptionGroup::on_option_arg_rectangle(), you
can just assign "m_arg_box = rect;" once you have decoded the
string 'value' and stored the result in 'rect'.
Have I misunderstood you? Probably, because I don't see what's the
problem.

Hello all,
I have a command line with an option "box" than is a Rectangle:
I would like to do :
$] prog --box="0 0 600 400"
Instead of :
$] prog --box-x="0" --box-y="0" --box-width="600" --box-height="400"
I wrote my programme in Gtkmm, so I have subclassed
Glib::OptionGroup and add this function :
void MyOptionGroup::add_entry(const Glib::OptionEntry& entry,
Gdk::Rectangle& arg) {
Glib::OptionGroup::add_entry(entry, sigc::mem_fun(*this,
&OptionGroup::on_option_arg_rectangle));
}
bool MyOptionGroup::on_option_arg_rectangle(const Glib::ustring&
option_name, const Glib::ustring& value, bool has_value)
{
bool succes = true;
// parse value to Gdk::Rectangle(0, 0, 600, 400);
// How I can set MyOptionGroup->m_arg_box ?
return succes;
}
How to store the parsed valuein the function on_option_rectangle()
PS : I tried to show you the code that I did but maybe I have it
all wrong
