[gnomemm] creating_control example

[Felix Breuer <felix fbreuer de>]

Hello again.

After having sucessfully compiled + installed ORBit2, I took a look a
libbonobomm and libbonobouimm. Both compiled and installed fine, however
the creating_control example in libbonobouimm does not compile. 

The problem is that ControlWidget derives from 
Gnome::Bonobo::Servers::Control, however that class does not have a
default constructor, which is implicitly called from the ControlWidget's
constructor. To me this looks like a structural problem, while the other
compile errors are caused by mere typos.

Here is the constructor:

ControlWidget::ControlWidget()
: m_Button("Click me")
{
  pack_start(m_Entry);
  pack_start(m_Button);

  show_all_children();
}

And here are the error messages:

ontrolwidget.cc: In constructor `ControlWidget::ControlWidget()':
controlwidget.cc:23: no matching function for call to 
   `Gnome::Bonobo::Servers::Control::Control()'
../../bonobomm/servers/control.h:79: candidates are:
