fluid.actions

Definitions for common tree actions; This is the Fluid tree equivalent to std.algorithm.

abstract class NodeSearchAction: fluid.tree.TreeAction, event_pipe.Publisher!(Node).Publisher;

Abstract class for tree actions that find and return a node.

```
@safe FocusRecurseAction focusRecurse(Node parent);
```
Set focus on the given node, if focusable, or the first of its focusable children. This will be done lazily during the next draw.

If focusing the given node is not desired, use focusRecurseChildren.

Parameters

Node parent Container node to search in.
```
@safe FocusRecurseAction focusRecurseChildren(Node parent);
@safe FocusRecurseAction focusChild(Node parent);
```
Set focus on the first of the node's focusable children. This will be done lazily during the next draw.

Parameters

Node parent Container node to search in.
```
@safe ScrollIntoViewAction scrollIntoView(Node node, bool alignToTop = false);
```
Scroll so the given node becomes visible.

Parameters

Node node Node to scroll to.

bool alignToTop If true, the top of the element will be aligned to the top of the scrollable area.
```
@safe ScrollIntoViewAction scrollToTop(Node node);
```
Scroll so that the given node appears at the top, if possible.
```
@safe NextFrameAction nextFrame(Node node);
```
Wait for the next frame. This action is a polyfill that can be used in tree action chains to make sure they're added during beforeTree.

`Node node`	Node to scroll to.
`bool alignToTop`	If true, the top of the element will be aligned to the top of the scrollable area.
