ResizeRequest	requestVertical(ResizeRequest top, ResizeRequest bottom, ResizeNode<T> node) Combines the two requests top and bottom into a new request.
double	resolveHorizontal(ResizeNode<T> node, ResizeRequest left, double deltaLeft, ResizeRequest right, double deltaRight) Called whenever a node has to grant two resize requests at the same time.
double	resolveVertical(ResizeNode<T> node, ResizeRequest top, double deltaTop, ResizeRequest bottom, double deltaBottom) Called whenever a node has to grant two resize requests at the same time.

Method Detail

requestHorizontal

ResizeRequest requestHorizontal(ResizeRequest left,
                                ResizeRequest right,
                                ResizeNode<T> node)

Combines the two request left and right into a new request.

Parameters:

left - the request from the left, can be null

right - the request from the right, can be null

node - the node for which the requests have to be merged

Returns:

a new request that somehow represents left and right or null to cancel the requests

requestVertical

ResizeRequest requestVertical(ResizeRequest top,
                              ResizeRequest bottom,
                              ResizeNode<T> node)

Combines the two requests top and bottom into a new request.

Parameters:

top - the request from the top, can be null

bottom - the request from the bottom, can be null

node - the node for which the requests have to be merged

Returns:

a new request that somehow represents top and bottom or null to cancel the requests

resolveHorizontal

double resolveHorizontal(ResizeNode<T> node,
                         ResizeRequest left,
                         double deltaLeft,
                         ResizeRequest right,
                         double deltaRight)

Called whenever a node has to grant two resize requests at the same time.

Parameters:

node - the node at which a conflict occurred

left - the request from the left child

deltaLeft - how much the left child would move the divider

right - the request from the right child

deltaRight - how much the right child would move the divider

Returns:

how much the divider should be moved

resolveVertical

double resolveVertical(ResizeNode<T> node,
                       ResizeRequest top,
                       double deltaTop,
                       ResizeRequest bottom,
                       double deltaBottom)

Called whenever a node has to grant two resize requests at the same time.

Parameters:

node - the node at which a conflict occurred

top - the request from the top child

deltaTop - how much the top child would move the divider

bottom - the request from the bottom child

deltaBottom - how much the bottom child would move the divider

Returns:

how much the divider should be moved
