This is a library that provides a set of tools for drawing regions with cursor.
npm install --save @madappgang/react-selectionsYou need to specify an area for the selections to be rendered inside of. Selections can't be drawn outside the container. The package provides a container component, which you should use to render as a parent node to your selections (and other components as well).
import { Selection, SelectionContainer } from '@madappgang/react-selections';You then simply wrap your area that you want to render selections above in the container:
const selectionArea = {
id: 1,
dimensions: {
height: 150,
width: 300
},
coordinates: {
x: 100,
y: 100
},
};
...
<SelectionContainer>
<Selection
area={selectionArea}
className="my-selection"
/>
...
<AnyOtherComponent />
...
</SelectionContainer>
...As you see you can render anything inside the container, it will recognize selections inside and pass them special props.
If you need a selection to be draggable/resizable you need to specify it explicitly with an interactive boolean property.
<Selection interactive area={area} />Then you have to provide a handler that is going to handle area updates.
...
constructor() {
...
this.state = {
selectionArea: { ... },
};
}
...
handleSelectionAreaUpdate(selectionArea) {
this.setState({ selectionArea });
}
render() {
return (
<SelectionContainer>
...
<Selection
interactive
area={this.selectionArea}
onAreaUpdate={this.handleSelectionAreaUpdate}
/>
</SelectionContainer>
);
}
