示例1: DeselectAll

void SelectionState::DeselectAll(BOOL RenderBlobs)
{
	// Find the selected objects in the tree;
	SelRange* Selected = GetApplication()->FindSelection();
	ERROR3IF( Selected==NULL, "Selection object is null in DeselectAll()");

	// Get the selected spread
 	Spread* pSpread = Document::GetSelectedSpread();
	ERROR3IF(pSpread == NULL,"NULL selected spread");

	// Make sure that we have a spread and a selection
	if (pSpread == NULL || Selected == NULL)
		return;

	// Find first selected node

#if !defined(EXCLUDE_FROM_RALPH)
	Node* pFirstSelectedNode = Selected->FindFirst();
	// If there is a selection, EOR blobs off, deselect nodes, and inform everybody
	if (pFirstSelectedNode != NULL && RenderBlobs)
	{
		// Go though and render all the EOR blobs off the screen

		// Find the Blob Manager
		BlobManager* BlobMgr = GetApplication()->GetBlobManager();
		ENSURE( BlobMgr!=NULL, "Blob Manager unexpectedly not there.");

		// Render all the blobs
		BlobMgr->RenderOff(NULL, pFirstSelectedNode->FindParentSpread());

		Tool* pTool = Tool::GetCurrent();
			
		// Get the tool to remove all its blobs before we deselect the nodes.
		// Only do this if the current tool dosent update itself on sel changed messages
		if (pSpread!=NULL && pTool!=NULL && !pTool->AreToolBlobsRenderedOnSelection())
			pTool->RenderToolBlobs(pSpread,NULL);
	}
#endif

	DeselectAll(pSpread->FindFirstChild());

	// Selection cache is no longer valid, so update and tell everyone that it has changed

	// *Note*, This used to be 'Selected->Update(TRUE)', but I (Will) removed the TRUE, so
	// that a message is NOT broadcast.  This should only be called from an operation,
	// and the op will send a message when it ends.

	Selected->Update();
