Hi @OmarKawach, Thanks! This is what I was looking for. Yeah, I still have to make a few steps to learn to work with these components... Web Components in general, and the new Map Components in the ArcGIS Javascript SDK in particular... I have slightly modified the Hide Compass example provided by @ReneRubalcava to take into account the rotation of the map - see code below. And yeah, don't forget to set the autoDestroyDisabled property of the component to be able to append and rempove the component multiple times. Thanks again, Egge-Jan <html>

<p>Kleine demonstratie app, gebouwd met <a href="https://developers.arcgis.com/javascript/latest/" target="_blank">ArcGIS Maps SDK for JavaScript</a>, en dan speciaal de recent geïntroduceerde <a href="https://developers.arcgis.com/javascript/latest/references/map-components/" target="_blank">Map Components</a>.</p>

<h3>Demo:</h3>
<p>Het toevoegen en verwijderen van een component, in dit geval het Compass, afhankelijk van de rotatie van de kaart.</p>
<p>De kaart is standaard noordgericht, en dan is de Compass button niet echt nodig. Maar als de gebruiker de kaart roteert met <code>Right-click + Drag</code>, dan verschijnt het Compass zodat men de kaartoriëntatie kan resetten. En zodra dat gebeurt is (de kaart is weer noordgericht), dan verdwijnt het Compass ook weer.<br><br>Let op:<br>Het is van belang dat je bij het arcgis-compass component de property <b>autoDestroyDisabled</b> instelt. Je wilt het component immers meerdere keren toevoegen en verwijderen, zonder dat het bij de eerste keer verwijderen automatisch vernietigd wordt.</p>

Hi, I am playing around with the new components in the ArcGIS Maps SDK for JavaScript 4.31 and I wondered: is there an easy way to show hide/components? For example the compass: Component Reference / Compass - Docs ⋅ Storybook As long as the map/view faces north (i.e. heading = 0), I do not need the compass at all. But yes, I want the compass to appear when the user rotates the map, to disappear again the moment the map faces north again, i.e. after the user clicked the compass to reset the view. With the good old widget I would do something like this: watchUtils.whenTrue(view, "stationary", function() {
if (view.rotation == 0){
view.ui.remove(compassWidget);
} else {
view.ui.add(compassWidget, "top-left");
}
}); How to accomplish something similar with the new components? TIA, Egge-Jan

Hi @ForrestLin, Thanks for checking this out. I think it works 'as designed': Esri, of course, wants you to use their portal, and - as you indicate - the summary you set there will appear in the popup. There is no way, as far as I know, to set this popup text in the code. Can someone from Esri confirm? Code wise, you can only set the title, which will then appear in the popup (like in my code snippet above).

Yes, when is the answer 🙂 when() may be leveraged once an instance of the class is created. https://developers.arcgis.com/javascript/latest/api-reference/esri-widgets-Editor.html#methods-summary Example // Although this example uses the BasemapGallery widget, any class instance that is a promise may use when() in the same way
let bmGallery = new BasemapGallery();
bmGallery.when(function(){
// This function will execute once the promise is resolved
}, function(error){
// This function will execute if the promise is rejected due to an error
}); Does this solve the issue? Egge-Jan

Hmmm, what is the source of your TileLayer? Can you set a description in the portal, as indicated in the first part of my answer above...?

Hi @ForrestLin, Your LocalBaseMapSource will contain one or more Basemaps. If the Basemap is coming from ArcGIS Online (or ArcGIS Enterprise) then you can edit the tooltip text in your portal: it is the description you give to the item. Alternatively, if your Basemap is coming from another source, you can give your Basemap a title which will pop up in the tooltip. See code snippet below. For the Basemap which is based on the WMTSLayer, it is the title "BRT Achtergrondkaart (PDOK)" which will show in the tooltip. HTH, Egge-Jan import Basemap from "@arcgis/core/Basemap";

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: <!DOCTYPE html>

Hi @Tom_Prutz, Good evening, I don't know whether your question is still relevant, as you posted it almost 2 weeks ago... Actually I think your code snippet should work, so we have got to find out why it is not working - as you say - in your case. You can find more information about reactiveUtils in the ArcGIS JS API Reference, and there it is suggested to put a question mark behind view. But I did test your sample without a question mark, and that did the job as well... reactiveUtils.when(
() => view?.stationary === true,
() => {
console.log("view is stationary now");
}); To see a working example you have a look at this blogpost ArcGIS JavaScript with UK data - URL.searchParams. It might seem an older post, but I just updated it tonight, to use reactiveUtils (instead of the deprecated, and now even completely removed, watchUtils which I used in an earlier version of the post). As you can see, the parameters in the URL are updated every time the view becomes stationary. So, in the end, the conclusion might be, that your issue is caused by your test setup. Can you please provide us with more information/code to explain what you are trying to do? Cheers, Egge-Jan

Hi @StephM, Can you please share the code snippet where you add your icons? In that way it will be easier for the community to provide suggestions on what to change to make it work (again) in the 4.29 version of the ArcGIS Maps SDK for JavaScript. I can provide you with an example - using an svg instead of base64, so maybe not completely what you are looking for... - that works fine in 4.29: function createZoomEntireCountryBtn() {
const zoomEntireCountryBtnDiv = document.createElement('div');
zoomEntireCountryBtnDiv.innerHTML = `
<div id="zoomEntireCountryBtn" class="esri-component esri-widget--button esri-widget" role="button">
<span title="Zoom uit op heel Nederland"><calcite-action><img src="nederland.svg" style="width:25px;height:25px;" alt="nederland"></calcite-action></span>
</div>`;
document.body.appendChild(zoomEntireCountryBtnDiv);
document.getElementById("zoomEntireCountryBtn").addEventListener("click", zoomEntireCountry);
} The actual file nederland.svg is 924x924 pixels in size, but renders perfectly on my custom button: Hope you will find a solution (and - maybe - share it here to the benefit of the community :-)) Cheers, Egge-Jan

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: ArcGIS Maps SDK for JavaScript example: Previous a... - Esri Community HTH, Egge-Jan

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? Cheers, Egge-Jan

Yes, as @BlakeTerhune suggests, you should really consider, while you are already migrating from 3.x to 4.x, to also leave the legacy AMD modules, with their require() statement, behind and switch to ES Modules instead. For a quick comparison between AMD and ES, you might have a look at this blog post by @AndyGup : ArcGIS API for JavaScript – Working with frameworks and build tools just got easier – Part 2 (esri.com). And sample apps, provided by Esri, ae available here: jsapi-resources/esm-samples at main · Esri/jsapi-resources · GitHub
