Can you clarify the difference between these two properties. I can understande they relate to Connection point thumb being dragged over the parent Diagram node elememnt, but i cant work out how the From and To distinctions are made, the documentation for both is the same. How do these properties relate to diagram actions? Cheers |

Hello Sorry about the documentation there. These properties are to indicate that an end of a connection is being dragged over a diagram node. When you drag the mouse on a connection point thumb, you start to create a connection. When the mouse then hovers over a node, the IsToConnectionDragOver property is set to true. When relocating a connection however, the user may either be relocating the source-end of the connection, or the destination-end of the connection. These two properties are to distinguish which end of the connection the user is dragging over the node. IsToConnectionDragOver is for the destination-end. The IsFromConnectionDragOver is for the source-end. When I say 'relocating' a connection, I am refering to hovering the mouse over an existing connection and then grabbing one of the relocation thumbs at one end of the connection. (These look like red circles by default) These properties are primerily used for triggers in the ConnectionPointThumb style to hide or display the thumb. When the destination-end of a connection is dragged over a node, only the connection points that can 'recieve' connections will appear. When the source-end of a connection is dragged over a node, only the connection points that can 'originate' connections will appear. - Jason |
