Re: How to fully expand a widget within a window?

[Samvel <ksamdev gmail com>]

However you add widgets to show they are properly and nicely packed in a 
window. But they are not affected as soon as you start resizing Window. The 
only remedy I've found is to connect method to signal_check_resize() of the 
main window:

  ...
  signal_check_resize().connect( sigc::mem_fun( *this, 
&MainWin::on_check_resize));
  ...

And then call resize_children() in MainWin::on_check_resize().
