A recursive definition:
`Block.tree`

is a list with the vertices of the "current" blocks,
some parameters for controlling the layout,
and possible some `block.trees`

:

`...\$Vertices`

The`vertices`

of the block.`...\$label`

A text string for the`label`

of the block. Will overwrite`"block-name"`

and`root.label`

.`...\$d`

Numeric. The heading bar (with the label) has a height of (`d`

+ 2) divided by 100, times the height of the window canvas.`...\$g`

Numeric. The vertices of the block are placed in an array with a height (width if`horizontal`

is set to FALSE) of`g`

divided by 100, times the height (width) of the window canvas. Thus this size will not decrease with the block size.`...\$f`

Numeric. If not`g`

is given: The the vertices of the block are placed in an array with a height (width if`horizontal`

is set to FALSE) of`f`

divided by 100, times the height (width) of the block. Thus this size is relative to the block size.`...\$G`

Numeric. (If the height of the block is 100 we are now left with`100 - 2 * delta - d - 2 - g`

for the blocks. ) The sub blocks (apart from`common.children`

) then have a of height (width, if`horizontal`

is set to FALSE) of`G`

divided by 100, times the height (width) of the window canvas. Thus the sub block size will not decrease with the block size. (If the height of the block is 100 we are now left with`100 - 2 * delta - d - 2 - g - G`

for the`common.children`

. )`...\$F`

Numeric. If not`G`

is given: The proportion`G`

of the remaining space are used for sub blocks (apart from`common.children`

) and the proportion`G`

of the space for blocks are used for`common.children`

.`...\$horizontal`

Logical. If`horizontal`

is set to TRUE, then the sub blocks, but`common.children`

, are placed side by side, else the blocks are placed vertically.`...\$closed`

Logical. If`closed`

is set to TRUE, then the block is initially drawn "closed", and the vertices and sub blocks of the block are not visible.`...\$vertices.last`

Logical. If`vertices.last`

then the vertices of the block are placed after the sub blocks.`...\$"block-name"`

`= list(...)`

Repeated zero, one or more times for sub blocks.`"block-name"`

is the label of the block, and`list(...)`

is a`Block.tree`

.`...\$common.children`

`= list(...)`

Omitted, or a list with common children of the other sub blocks of the block. The list is again a`Block.tree`

.

A list with components

`BlockTree` |
A tree of blocks, each of class |

`Vertices` |
The list of vertices, with the positions updated such the vertices has positions within the blocks. |

Ancestors and descendants are set in `setTreeBlocks`

.
Ancestors are used in the function `returnBlockEdgeList`

to
find the edges between blocks and between blocks and vertices.

Descendants are used in `dynamicGraphMain`

when closing, opening and moving blocks,
and when adding or dropping edges from and to blocks.

The methods `NodeAncestors`

, `NodeAncestors<-`

`NodeDescendants`

and `NodeDescendants<-`

can be used on the block list resulting of
`blockTreeToList`

on the block tree.
