Sorry for the late reply, but it seems as if the list email is not making it
to me.
The compile line looks like this:
g++ -pipe -M `pkg-config gtkmm-2.0 --cflags` `pkg-config glib-2.0 --cflags`
`pkg-config libgtkhtml-2.0 --cflags` `pkg-config gnome-vfs-2.0 --cflags`
testgtkhtml.cpp -o testgtkhtml.o
And the link line like this:
g++ testgtkhtml.o `pkg-config gtkmm-2.0 --libs` `pkg-config glib-2.0 --libs`
`pkg-config libgtkhtml-2.0 --libs` `pkg-config gnome-vfs-2.0 --libs` -o
testgtkhtml
The other thing that I noticed about this way of implementing this
is that you are limited to a single instance of a window that can render
HTML. I was starting to create a C++ wrapper class, but found out that the
lines:
g_signal_connect( G_OBJECT( document ), "request_url", G_CALLBACK(
>khtml::url_requested ), NULL );
g_signal_connect( G_OBJECT( document ), "link_clicked", G_CALLBACK(
>khtml::link_clicked ), NULL );
are proving to be difficult to resolve. How would you connect gtk+
signals to a C++ class instance? That appears to be the question now, for
me at least.
