Signals

[Martin Dolezal <tvtv centrum cz>]

Hello,
I am quite new to gtkmm, working with it only for few weekends. I was 
using signals for Buttons, CheckButtons, etc, working fine. But I also 
used signal for Gtk::Paned in the way:

myHPaned.signal_button_press_event().connect(sigc::mem_fun(*this, 
&MyMain::onHPanedClick));

My intention is to detect double click on divider between left and right 
part of this HPaned and respond to it in some way. That's working 
(checking GdkEventButton's type in onHPanedClick). But in right part of 
this HPaned I have Frame (added by pack2) and in this frame I have 
Gtk::Notebook. I just realized that double-clicking on this Notebook's 
pages' captions calls onHPanedClick too. I didn't know that connected 
signals are sent to all children widgets too. Is that so or do I connect 
signal in some wrong way? And second question - what's the proper way to 
detect if the double-click was made on the HPaned itself (well, on the 
divider in the middle to be correct) and not on its children? Should I 
somehow use GdkWindow *window in GdkEventButton parameter received by 
onHPanedClick?

Thanks,
Martin
