Re: Dragging a window

[lecas malecas <darkiiiiii gmail com>]

Yep, that works. thanks!

Just another doubt, to change the cursor of the mouse (the image).


I think its something like this:

const Glib::RefPtr< Gdk::Cursor > cursor = Gdk::Cursor::create(Gdk::HAND1);

get_window()->set_cursor(cursor);

but I'm getting a seg. fault in the last line :(
