Re: Writing C++ apps with Gtk?

[Michael Hudson <mwh21 cam ac uk>]

This is a bit of a guess, but is cbHello an ordinary member function?
If it is then there will be an implicit 'this' parameter passed to it
which gtk+ will not be expecting to pass to it, and things will go
generally pear-shaped.

Try making it a static function.

You'll probably end up writing functions like this:

void TopLevel::static_cbHello( GtkWidget *widget, gpointer data )
{
  ((TopLevel*)data)->cbHello();
}

I seem to remeber doing that a lot when writing stuff for PowerPlant on
the Mac.

Hope this helps
