示例1: ViewReloadBoard

void PCB_EDIT_FRAME::ViewReloadBoard( const BOARD* aBoard ) const
{
    KIGFX::VIEW* view = GetGalCanvas()->GetView();
    view->Clear();

    // All of PCB drawing elements should be added to the VIEW
    // in order to be displayed

    // Load zones
    for( int i = 0; i < aBoard->GetAreaCount(); ++i )
    {
        view->Add( (KIGFX::VIEW_ITEM*) ( aBoard->GetArea( i ) ) );
    }

    // Load drawings
    for( BOARD_ITEM* drawing = aBoard->m_Drawings; drawing; drawing = drawing->Next() )
    {
        view->Add( drawing );
    }

    // Load tracks
    for( TRACK* track = aBoard->m_Track; track; track = track->Next() )
    {
        view->Add( track );
    }

    // Load modules and its additional elements
    for( MODULE* module = aBoard->m_Modules; module; module = module->Next() )
    {
        // Load module's pads
        for( D_PAD* pad = module->Pads().GetFirst(); pad; pad = pad->Next() )
        {
            view->Add( pad );
        }

        // Load module's drawing (mostly silkscreen)
        for( BOARD_ITEM* drawing = module->GraphicalItems().GetFirst(); drawing;
                drawing = drawing->Next() )
        {
            view->Add( drawing );
        }

        // Load module's texts (name and value)
        view->Add( &module->Reference() );
        view->Add( &module->Value() );

        // Add the module itself
        view->Add( module );
    }

    // Segzones (equivalent of ZONE_CONTAINER for legacy boards)
    for( SEGZONE* zone = aBoard->m_Zone; zone; zone = zone->Next() )
    {
        view->Add( zone );
    }

    // Add an entry for the worksheet layout
    KIGFX::WORKSHEET_VIEWITEM* worksheet = new KIGFX::WORKSHEET_VIEWITEM(
        std::string( aBoard->GetFileName().mb_str() ),
        std::string( GetScreenDesc().mb_str() ),
        &GetPageSettings(), &GetTitleBlock() );
    BASE_SCREEN* screen = GetScreen();
    if( screen != NULL )
    {
        worksheet->SetSheetNumber( GetScreen()->m_ScreenNumber );
        worksheet->SetSheetCount( GetScreen()->m_NumberOfScreens );
    }

    view->Add( worksheet );

    // Add an entry for the ratsnest
    RN_DATA* ratsnest = aBoard->GetRatsnest();
    ratsnest->ProcessBoard();
    ratsnest->Recalculate();
    view->Add( new KIGFX::RATSNEST_VIEWITEM( ratsnest ) );

    view->SetPanBoundary( worksheet->ViewBBox() );
    view->RecacheAllItems( true );

    if( IsGalCanvasActive() )
        GetGalCanvas()->Refresh();
}
