hide tooltips associated with visualization when removing the visualization

[NoobTW]

Hi, I'm using treemap in this package. It works well but after I hide the treemap, the tooltip doesn't hide. The .d3plus-tooltip is still there in the DOM.

@NoobTW can you share the code you have written to hide the Treemap?

Not sure if I did this right, but here's the code: https://github.com/NoobTW/od-freq/blob/master/src/App.js#L110

Thanks for sharing @NoobTW. In the meantime, before the fix is implemented, you might be able to hack it (I haven't tested this though). At the top of the render function, save the handleClick function to a variable:

const handleClick = this.handleClick.bind(this);

And then try this for your click function:

on:
  click: function(d) {
    this._tooltipClass.data([]).render();
    handleClick(d);
  }
}

This is all based on the default internal click function, which has access to the tooltip through it's context: https://github.com/d3plus/d3plus-viz/blob/master/src/on/click.js

Thanks for the hack, but I'm unable to access this in click function.

on: {
	click: function(d) {
		// this._tooltipClass.data([]).render();
		console.log(this)  // This is undefined.
		handleClick(d); // Still works because I saved it to a variable.
	}
}
