Re: [platform-swt-dev] Does SWT (in Eclipse 3.2 or w.4) support embeddin

["Dharmesh Bhakta" <bhaktadn@xxxxxxxxx>]

Thanks Steve for the quick response. Let me admit this first, I am a
newbie to both SWT and GTK so I am not familiar with all the concepts
around it but trying to learn as fast as i can.

Yes, That's exactly I want. I would like to make one window appear
inside the another. Let's say I have a simple native application,
gnaome-calculator. I would like the gnome-calculator to appear inside
a view under eclipse. For now, I'm just trying the gnome-calculator as
an example. But If I can get this to work, I should be able to get
other native business applications to work under eclipse.

I was hoping that the OS.gtk_widget_reparent(widget, parent) would
have given me the same results as I got on Windows. But it somehow did
not work as expected.

So, I did a little investigation on the GtkPlug & GtkSocket which uses
the XEMBED protocol. Doing deeper investigation on the SWT's side and
it appears that the nativeComposite.embeddedHandle is the socket_id
where I would like the gnome-calculator to appear. So now, I created a
new Gtk Plug using the OS.gtk_plug_new passing the socket_id of the
nativeComposite.embeddedHandle as the parameter.
This method returns a reference to the plug widget. I have been
successful in adding a new GTK widget to this plug widget and display
it inside an Eclipse view. :-) But I've been able to add a Window to
the plug widget. Any suggestions?

So now, the issue I will have here is how do I add the
gnome-calculator to the plug widget so I can display inside the
Eclipse Vieww. The only information I have for now is the X Window id
for the ganome-caculator. Some now I need to find a way to get the
widget representation of  X Window id. Any suggestion here?

THanks in advance for your help.
