Enumeration Type Documentation

enum IlvLayoutAlignment

This enumeration defines values used to specify the alignment of nodes.

Enumerator
IlvLayoutEastAlignment	Nodes are aligned at the east border.
IlvLayoutWestAlignment	Nodes are aligned at the west border.
IlvLayoutNorthAlignment	Nodes are aligned at the north border.
IlvLayoutSouthAlignment	Nodes are aligned at the south border.
IlvLayoutCenterAlignment	All parent nodes are aligned centered with respect to their children. Nodes are aligned at the center.
IlvLayoutBorderCenterAlignment	Nodes are centered between the left and right border.
IlvLayoutTipOverAlignment	Nodes are placed in the tip over style.
IlvLayoutMixedAlignment	Mixed alignment; each node can have a different alignment.

enum IlvTreeLayoutMode

This enumeration defines values used to specify the tree layout mode.

Enumerator
IlvTreeLayoutFreeMode	Free layout mode. All links flow roughly in the flow direction; parents and sibling nodes are aligned according to the specified alignment option, but nodes of different tree branches are not justified to each other.
IlvTreeLayoutLevelMode	Level layout mode. All links flow roughly in the flow direction. All nodes are organized in levels and are justified at their borders or center according to the level justification option. Tip over alignment is not possible, all other alignment options are possible.
IlvTreeLayoutRadialMode	Radial layout mode. The root node is in the center, the links flow radially away from the center, and the nodes are placed in circular layers around the root node.
IlvTreeLayoutAlternatingRadialMode	Alternating radial layout mode. The root node is in the center, the links flow radially away from the center, and the nodes are placed in circular layers around the root node. In order to optimize space, siblings may be placed alternating in two different circular layers.
IlvTreeLayoutTipOverMode	Fast tip over layout mode. In this layout mode, the tree layout algorithm tries to optimize the layout automatically to fit best the specified aspect ratio by calculating which individual nodes need tip over alignment and which nodes can use the specified alignment. The layout algorithm uses a fast heuristic.
IlvTreeLayoutTipLeavesOverMode	Tip over layout mode at leaves. In this layout mode, the tree layout algorithm tries to optimize the layout automatically to fit best the specified aspect ratio by calculating which individual nodes need tip over alignment and which nodes can use the specified alignment. The layout algorithm uses a heuristic that checks whether leaf nodes should be tipped over.
IlvTreeLayoutTipRootsOverMode	Tip over layout mode at roots. In this layout mode, the tree layout algorithm tries to optimize the layout automatically to fit best the specified aspect ratio by calculating which individual nodes need tip over alignment and which nodes can use the specified alignment. The layout algorithm uses a heuristic that checks whether root nodes should be tipped over.
IlvTreeLayoutTipRootsAndLeavesOverMode	Tip over layout mode at roots and leaves. In this layout mode, the tree layout algorithm tries to optimize the layout automatically to fit best the specified aspect ratio by calculating which individual nodes need tip over alignment and which nodes can use the specified alignment. The layout algorithm uses a heuristic that checks whether root nodes and leaf nodes should be tipped over.
