◆ RemoveThumbnailFromNode()

virtual void GraphModelIntegration::GraphControllerRequests::RemoveThumbnailFromNode ( GraphModel::NodePtr node )

pure virtual

Remove the thumbnail from a specified node. If you created your own custom ThumbnailItem and set it using SetThumbnailOnNode, then ownership is passed back to whoever calls this method so they are in charge of deleting it.

Parameters

node	Node to remove the thumbnail from

◆ SetThumbnailImageOnNode()

virtual void GraphModelIntegration::GraphControllerRequests::SetThumbnailImageOnNode	(	GraphModel::NodePtr	node,
		const QPixmap &	image
	)

pure virtual

Embed a thumbnail image on a specified node. This is the most straightforward use-case where the client just wants to show a static image. The thumnbnail image can be updated after being set using this same API.

Parameters

node	Node to add the thumbnail on
image	Pixmap for the image of the thumbnail

◆ SetThumbnailOnNode()

virtual void GraphModelIntegration::GraphControllerRequests::SetThumbnailOnNode	(	GraphModel::NodePtr	node,
		ThumbnailItem *	item
	)

pure virtual

Embed a custom thumbnail item on a specified node. This allows the client to implement their own ThumbnailItem to display anything they want by overriding paint() method. Ownership of the ThumbnailItem is passed to the node layout.

Parameters

node	Node to add the thumbnail on
item	Custom item for the thumbnail

◆ SetWrapperNodeActionString()

virtual void GraphModelIntegration::GraphControllerRequests::SetWrapperNodeActionString	(	GraphModel::NodePtr	node,
		const char *	actionString
	)

pure virtual

Set the action string for the specified node (used by wrapper nodes for setting the action widget label)

◆ UnwrapNode()

virtual void GraphModelIntegration::GraphControllerRequests::UnwrapNode	(	GraphModel::NodePtr	wrapperNode,
		GraphModel::NodePtr	node
	)

pure virtual

Unwrap a node from a wrapper node This results in a no-op if node isn't actually wrapped on the wrapperNode
