Re: RadioToolButton

* Use get_group() to retrieve this group and pass it to other radio buttons to assign
* them to this group.

I've given the suggested work-around a try, and have run into a slightly different problem.  Instead of having all buttons in the group permently pressed, its starts out as one pressed, however, when I press another button, the first does not become 'un-pressed'.  It does eventually become unpressed as i press more buttons though.

Here's the code I'm working from.  If anyone can see what I'm doing wrong that'd be great.  ty

#include <gtkmm.h>


class MyToolbar : public Gtk::Toolbar
{

public:

  MyToolbar()
  {
    set_toolbar_style( Gtk::TOOLBAR_ICONS );

    m_center = new Gtk::RadioToolButton( m_group, Gtk::Stock::JUSTIFY_CENTER );

    m_group = m_center->get_group();

    m_left = new Gtk::RadioToolButton( m_group, Gtk::Stock::JUSTIFY_LEFT );
    m_right = new Gtk::RadioToolButton( m_group, Gtk::Stock::JUSTIFY_RIGHT );


    append( *m_center );
    append( *m_left );
    append( *m_right );
  }
     
private:

  Gtk::RadioButtonGroup m_group;

  Gtk::RadioToolButton* m_center;
  Gtk::RadioToolButton* m_left;
  Gtk::RadioToolButton* m_right;

};


class ToolWindow : public Gtk::Window
{

public:

  ToolWindow()
  {
    set_border_width(10);
    set_default_size( 300, 200 );
   
    m_vbox.pack_start( m_toolbar, Gtk::PACK_SHRINK );

    add( m_vbox );

    show_all_children();
  }

protected:

  Gtk::VBox m_vbox;
  MyToolbar m_toolbar;

};


int main( int argc, char* argv[] )
{
  Gtk::Main kit(argc, argv);
  ToolWindow window;

  Gtk::Main::run( window );

  return 0;
}
