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();
