Provide callback to cancel the zoom on double click

[BrianWalters]

Just like beforeMouseDown, we need a way to cancel the double click zoom event depending on the event context. For example, if we have buttons overlayed on the panzoom area, a user double-clicking a button shouldn't initiate a zoom.

There is also no way I could see to disable the double click zoom entirely, if say someone created their own zoom in/out buttons, or maybe they want to implement some other function for a double click.

Hi @BrianWalters . I hope you are doing good. Were you able to figure out something. I am stuck in the same issue :)

For now, in your custom button/overlay add event.stopPropagation() like this:

function doTheThing(event) {
	hackTheGibson();
	event.stopPropagation();
	alert("event propagation halted.");
}

buttonOverlay.addEventListener("dblclick", doTheThing);

But, yes we need an option to disable double click Zoom, something like this doubleClickZoom: false

panzoom(element, {
  zoomDoubleClickSpeed: 1,  // disables zoom on double click
});
