A Label displays a piece of text, which is specified through the <code>Text</code> property. Other properties, all of which can be set in the Designer or Blocks Editor, control the appearance and placement of the text.

Un''etichetta visualizza del testo, specificato tramite la proprietà <code>Testo</code>. Altre proprietà, tutte impostabili nel Designer o nell''editor dei blocchi, controllano l''aspetto e il posizionamento del testo.

A sensor component that can measure the light level.

LineString is a component for drawing an open, continuous sequence of lines on a Map. To add new points to a LineString in the designer, drag the midpoint of any segment away from the line to introduce a new vertex. Move a vertex by clicking and dragging the vertex to a new location. Clicking on a vertex will delete the vertex, unless only two remain.

A visible component that indicates the progress of an operation using an animated linear bar.

<p>A button that, when clicked on, displays a list of texts for the user to choose among. The texts can be specified through the Designer or Blocks Editor by setting the <code>ElementsFromString</code> property to their string-separated concatenation (for example, <em>choice 1, choice 2, choice 3</em>) or by setting the <code>Elements</code> property to a List in the Blocks editor.</p><p>Setting property ShowFilterBar to true, will make the list searchable. Other properties affect the appearance of the button (<code>TextAlignment</code>, <code>BackgroundColor</code>, etc.) and whether it can be clicked on (<code>Enabled</code>).</p>

<p>Un pulsante che, quando viene cliccato, mostra all''utente una lista di testi tra cui scegliere. I testi possono essere specificati tramite Progettazione o l''editor dei blocchi impostando la proprietà <code>ElementiDaStringa</code> a una stringa contenente la loro concatenazione (ad esempio, <em>scelta 1, scelta 2, scelta 3</em>) o impostando la proprietà <code>Elementi</code> a una Lista nell''editor dei blocchi.</p><p>Impostare la proprietà MostraBarraFiltro a Vero, abiliterà la ricerca nella lista. Altre proprietà influenzano l''aspetto del pulsante (<code>AllineamentoTesto</code>, <code>ColoreSfondo</code>, etc.) e se è possibile cliccarci sopra (<code>Abilitato</code>).</p>

Non-visible component providing location information, including longitude, latitude, altitude (if supported by the device), speed (if supported by the device), and address. This can also perform "geocoding", converting a given address (not necessarily the current one) to a latitude (with the <code>LatitudeFromAddress</code> method) and a longitude (with the <code>LongitudeFromAddress</code> method).</p><p>In order to function, the component must have its <code>Enabled</code> property set to True, and the device must have location sensing enabled through wireless networks or GPS satellites (if outdoors).</p>Location information might not be immediately available when an app starts. You''ll have to wait a short time for a location provider to be found and used, or wait for the LocationChanged event

Componente non visibile che fornisce informazioni sulla posizione, tra cui longitudine, latitudine, altitudine (se supportata dal dispositivo), e indirizzo. Esso può anche eseguire la geolocalizzazione, convertendo un indirizzo (non necessariamente quello corrente) in una latitudine (con il metodo <code>LatitudineDaIndirizzo</code>) e una longitudine (con il metodo <code>LongitudineDaIndirizzo</code>).</p>
<p>Per funzionare, il componente deve avere la sua proprietà <code>Abilitato</code> a valore Vero, e il dispositivo deve avere la rilevazione di posizione abilitata tramite rete senza fili o satelliti GPS (se all''aperto).</p>
Le informazioni sulla posizione possono essere non immediatamente disponibili all''avvio di un''applicazione. Dovrai aspettare alcuni istanti perché un provider di posizione venga trovato e usato, o attendere l''evento PosizioneCambiata

<p>Non-visible component that measures the ambient geomagnetic field for all three physical axes (x, y, z) in Tesla https://en.wikipedia.org/wiki/Tesla_(unit).</p>

<p>A two-dimensional container that renders map tiles in the background and allows for multiple Marker elements to identify points on the map. Map tiles are supplied by OpenStreetMap contributors and the United States Geological Survey.</p><p>The Map component provides three utilities for manipulating its boundaries within App Inventor. First, a locking mechanism is provided to allow the map to be moved relative to other components on the Screen. Second, when unlocked, the user can pan the Map to any location. At this new location, the &quot;Set Initial Boundary&quot; button can be pressed to save the current Map coordinates to its properties. Lastly, if the Map is moved to a different location, for example to add Markers off-screen, then the &quot;Reset Map to Initial Bounds&quot; button can be used to re-center the Map at the starting location.</p>

<p>An icon positioned at a point to indicate information on a map. Markers can be used to provide an info window, custom fill and stroke colors, and custom images to convey information to the user.</p>

Non-visible component that communicates with a Web service and stores media files.
