Hi I am looking to add pan controls in the form of arrows to an ArcGIS4 JS map but have been struggling to find the specific api to allow me to do this.
I was wondering if anyone had any input on how I could go about doing this?
Thank you
Hi @azy141,
Can you please explain why you would want to add pan controls to your ArcGIS4 JS map? The reason I ask this, is because I think it is not necessary at all to add such controls to the user interface.
It is quite easy to pan the map - grabbing it with a left mouse click, using the arrow keys on your keyboard or just with your fingers on a mobile device.
So, the map is 'panable' by default. There is no need to add controls to activate a pan modus.
What is your opinion about this?

I was given this assignment as we are looking at building controls that are easier to use for accessibility reasons.
I think you will have to add your own buttons to the map, or actually to the view.ui, with a function to move the center of the map an X number of units to the N/E/S/W when the respective button is clicked.
I have never added pan buttons to the ui myself, but for some inspiration you may have a look at this example, where I do add a custom 'previous extent' and 'next extent' button to the user interface:

Hi. I would assume you could just add some new html elements and change the MapView (view) by an x,y distance on each click.
Here I added custom zoom in/out buttons in a similar way-
There is a DirectionalPad widget, it's not in the corners though, not sure if that would meet your needs

This is perfect thank you
Hi @ReneRubalcava,
Cool. Didn't know about this little widget. I did quickly create a small sample to test it (see code below) and it works fine. I do like this little compass indicating the orientation of the map (when not 0), allowing you to reset the map orientation (to 0).
Of course I cannot speak for the original poster, but I think this offers most of the functionality requested.
Here is my little sample:

Do you know how I could go about overriding the icons used in this d pad?
const directionalPad = new DirectionalPad({
view: view
icon: "esri-icon-handle-horizontal",
})
