The following source code example demonstrates how to display a toolbar in a toolbar collection, or workspace, file. This example assumes that there is a toolbar collection file (*.tb) with the same file name as the plug-in, and that the toolbar collection is stored in the same folder as the plug-in.

Rhino 4.0, C++

  BOOL ShowPlugInToolbar()
  {
    // Get reference to our plug-in object
    CTestPlugIn& plugin = GetTestPlugIn();


    // Get the full path to plug-in file
    ON_wString file_name;
    plugin.GetPlugInFileName( file_name );


    // Build the toolbar collection file name
    wchar_t drive[_MAX_DRIVE];
    wchar_t dir[_MAX_DIR];
    wchar_t fname[_MAX_FNAME];
    _wsplitpath( file_name, drive, dir, fname, 0 );


    ON_wString collection_name;
    collection_name.Format( L"%s%s%s.tb", drive, dir, fname );


    BOOL rc = FALSE;


    // Get reference to Rhino's toolbar manager 
    CRhinoAppUiToolBarManager& tm = RhinoApp().RhinoUiToolBarManager();


    // Load the toolbar collection, if necessary.
    if( tm.ReadFile(collection_name, true, true, true) )
    {
      // Get the toolbar collection
      const CRhinoUiToolBarCollection* col = tm.Collection( tm.CollectionIndex(collection_name, false) );
      if( col )
      {
        // Find the "Default" toolbar
        const CRhinoUiToolBar* tb = col->ToolBar( col->FindToolBar(L"Default") );
        if( tb && tm.ShowToolBar(tb, true, false) ) // Load it
          rc = TRUE;
      }
    }


    return rc;
  }

Rhino 3.0, C++

  BOOL ShowPlugInToolbar()
  {
    // Get reference to our plug-in object
    CTestPlugIn& plugin = GetTestPlugIn();


    // Get the full path to plug-in file
    ON_wString file_name;
    plugin.GetPlugInFileName( file_name );


    // Build the toolbar collection file name
    wchar_t drive[_MAX_DRIVE];
    wchar_t dir[_MAX_DIR];
    wchar_t fname[_MAX_FNAME];
    _wsplitpath( file_name, drive, dir, fname, 0 );


    ON_wString collection_name;
    collection_name.Format( L"%s%s%s.tb", drive, dir, fname );


    // Get reference to Rhino's toolbar manager 
    CRhinoToolBarManager& tm = ToolBarManager(); 


    // See if the toolbar collection is already open
    int collection_index = tm.CollectionIndex( collection_name, FALSE );
    if( collection_index < 0 )
    {
      // Open the toolbar collection
      collection_index = tm.OpenCollection( collection_name );
      if( collection_index >= 0 )
      {
        // Help Rhino figure out where all toolbars are supposed
        // to be positioned
        AFX_MANAGE_STATE( ::RhinoApp().RhinoModuleState() );
        ((CFrameWnd*)AfxGetMainWnd())->RecalcLayout();
      }
    }


    BOOL rc = FALSE;


    if( collection_index < 0 )
      return rc;


    // See if our toolbar is available
    int toolbar_index = tm.ToolBarIndex( collection_index, L"Default" );
    if( toolbar_index >= 0 )
    {
      // If the toolbar is not visible, display it
      if( !tm.IsToolBarVisisble(collection_index, toolbar_index) )
        rc = tm.ShowToolBar( collection_index, toolbar_index, TRUE );
      else 
        rc = TRUE;
    }
    return rc;
  }
