class UseSignal

class UseSignal<SENDER, ARGS> extends React.Component<
    IUseSignalProps<SENDER, ARGS>,
    IUseSignalState<SENDER, ARGS>
> {}

UseSignal provides a way to hook up a Lumino signal to a React element, so that the element is re-rendered every time the signal fires.

It is implemented through the "render props" technique, using the children prop as a function to render, so that it can be used either as a prop or as a child of this element https://reactjs.org/docs/render-props.html

Example as child:

function LiveButton(isActiveSignal: ISignal<any, boolean>) {
 return (
   <UseSignal signal={isActiveSignal} initialArgs={true}>
    {(_, isActive) => <Button isActive={isActive}>}
   </UseSignal>
 )
}

Example as prop:

function LiveButton(isActiveSignal: ISignal<any, boolean>) {
 return (
   <UseSignal
     signal={isActiveSignal}
     initialArgs={true}
     children={(_, isActive) => <Button isActive={isActive}>}
   />
 )
}

scrollToItem: (
    index: number,
    align?: WindowedList.ScrollToAlign,
    margin?: number,
    alignPreference?: WindowedList.BaseScrollToAlignment
) => Promise<void>;

Scroll to the specified item.
By default, the list will scroll as little as possible to ensure the item is fully visible (auto). You can control the alignment of the item though by specifying a second alignment parameter. Acceptable values are:
auto - Automatically align with the top or bottom minimising the amount scrolled, If alignPreference is given, follow such preferred alignment. If item is smaller than the viewport and fully visible, do not scroll at all. smart - If the item is significantly visible, don't scroll at all (regardless of whether it fits in the viewport). If the item is less than one viewport away, scroll so that it becomes fully visible (following the auto heuristics). If the item is more than one viewport away, scroll so that it is centered within the viewport (center if smaller than viewport, top-center otherwise). center - Align the middle of the item with the middle of the viewport (it only works well for items smaller than the viewport). top-center - Align the top of the item with the middle of the viewport (works well for items larger than the viewport). end - Align the bottom of the item to the bottom of the list. start - Align the top of item to the top of the list.

    alignPreference?: WindowedList.BaseScrollToAlignment
) => number;

Get the scroll offset to display an item in the viewport.
By default, the list will scroll as little as possible to ensure the item is fully visible (auto). You can control the alignment of the item though by specifying a second alignment parameter. Acceptable values are:
auto - Automatically align with the top or bottom minimising the amount scrolled, If alignPreference is given, follow such preferred alignment. If item is smaller than the viewport and fully visible, do not scroll at all. smart - If the item is significantly visible, don't scroll at all (regardless of whether it fits in the viewport). If the item is less than one viewport away, scroll so that it becomes fully visible (following the auto heuristics). If the item is more than one viewport away, scroll so that it is centered within the viewport (center if smaller than viewport, top-center otherwise). center - Align the middle of the item with the middle of the viewport (it only works well for items smaller than the viewport). top-center - Align the top of the item with the middle of the viewport (works well for items larger than the viewport). end - Align the bottom of the item to the bottom of the list. start - Align the top of item to the top of the list.

property anchor

anchor: IAnchor;

The referent anchor rectangle to which the hover box is bound.
#### Notes In an editor context, this value will typically be the cursor's coordinate position, which can be retrieved via calling the getCoordinateForPosition method.

property host

host: HTMLElement;

The node that hosts the anchor.
#### Notes The visibility of the elements under hover box edges within this host node is the heuristic that determines whether the hover box ought to be visible.

property maxHeight

maxHeight: number;

The maximum height of a hover box.
#### Notes This value is only used if a CSS max-height attribute is not set for the hover box. It is a fallback value.

property minHeight

minHeight: number;

The minimum height of a hover box.

property node

node: HTMLElement;

The hover box node.

property offset

offset?: {
    horizontal?: number;
    vertical?: {
        above?: number;
        below?: number;
    };
};

Optional pixel offset values added to where the hover box should render.
#### Notes This option is useful for passing in values that may pertain to CSS borders or padding in cases where the text inside the hover box may need to align with the text of the referent editor.
Because the hover box calculation may render a box either above or below the cursor, the vertical offset accepts above and below values for the different render modes.

property outOfViewDisplay

outOfViewDisplay?: {
    top?: OutOfViewDisplay;
    bottom?: OutOfViewDisplay;
    left?: OutOfViewDisplay;
    right?: OutOfViewDisplay;
};

How to position the hover box if its edges extend beyond the view of the host element. Value 'sticky' positions the box at the (inner or outer) edge of the host element.
#### Notes The default value for each edge is 'hidden-inside' for left and top, and hidden-outside for right and bottom edges.

property privilege

privilege?: 'above' | 'below' | 'forceAbove' | 'forceBelow';

If space is available both above and below the anchor, denote which location is privileged. Use forceBelow and forceAbove to mandate where hover box should render relative to anchor.
#### Notes The default value is 'below'.

property size

size?: {
    width: number;
    height: number;
};

Exact size of the hover box. Pass it for faster rendering (allowing the positioning algorithm to to place it immediately at requested position).

property style

style?: CSSStyleDeclaration;

If the style of the node has already been computed, it can be passed into the hover box for geometry calculation.

        itemMetadata: WindowedList.ItemMetadata;
        currentOffset: number;
    },
    alignPreference?: WindowedList.BaseScrollToAlignment
) => number;

Get the scroll offset to display an item in the viewport.
By default, the list will scroll as little as possible to ensure the item is fully visible (auto). You can control the alignment of the item though by specifying a second alignment parameter. Acceptable values are:
auto - Automatically align with the top or bottom minimising the amount scrolled, If alignPreference is given, follow such preferred alignment. If item is smaller than the viewport and fully visible, do not scroll at all. smart - If the item is significantly visible, don't scroll at all (regardless of whether it fits in the viewport). If the item is less than one viewport away, scroll so that it becomes fully visible (following the auto heuristics). If the item is more than one viewport away, scroll so that it is centered within the viewport (center if smaller than viewport, top-center otherwise). center - Align the middle of the item with the middle of the viewport (it only works well for items smaller than the viewport). top-center - Align the top of the item with the middle of the viewport (works well for items larger than the viewport). end - Align the bottom of the item to the bottom of the list. start - Align the top of item to the top of the list.
Parameter index
Item index
Parameter align
Where to align the item in the viewport
Parameter margin
In 'smart' mode the viewport proportion to add
Parameter precomputed
Precomputed values to use when windowing is disabled.
Parameter alignPreference
Allows to override the alignment of item when the auto heuristic decides that the item needs to be scrolled into view.
Returns
The needed scroll offset

method getRangeToRender

getRangeToRender: (options?: {
    virtual?: boolean;
}) => WindowedList.WindowIndex | null;

Compute the items range to display.
It returns ``null`` if the range does not need to be updated.
Parameter options
Control how the range is computed. - virtual: If true, return a virtual range without updating the current window. If false or omitted, update and return the actual window range.
Returns
The current items range to display

method getSpan

Return the viewport top position and height for range spanning from ``startIndex`` to ``stopIndex``.
Parameter start
First item in viewport index
Parameter stop

Returns
The viewport top position and its height
