<section id="objects">
<h1>Objects<a class="headerlink" href="#objects" title="Link to this heading"></a></h1>
<p>In LVGL the <strong>basic building blocks</strong> of a user interface are the
objects, also called <em>Widgets</em>. For example a
<a class="reference external" href="/widgets/btn">Button</a>, <a class="reference external" href="/widgets/label">Label</a>,
<a class="reference external" href="/widgets/img">Image</a>, <a class="reference external" href="/widgets/list">List</a>,
<a class="reference external" href="/widgets/chart">Chart</a> or <a class="reference external" href="/widgets/textarea">Text area</a>.</p>
<p>You can see all the <a class="reference external" href="/widgets/index">Object types</a> here.</p>
<p>All objects are referenced using an <a class="reference internal" href="../API/core/lv_obj.html#_CPPv48lv_obj_t" title="lv_obj_t"><code class="xref cpp cpp-type docutils literal notranslate"><span class="pre">lv_obj_t</span></code></a> pointer as a handle.
This pointer can later be used to set or get the attributes of the
object.</p>
<section id="attributes">
<h2>Attributes<a class="headerlink" href="#attributes" title="Link to this heading"></a></h2>
<section id="basic-attributes">
<h3>Basic attributes<a class="headerlink" href="#basic-attributes" title="Link to this heading"></a></h3>
<p>All object types share some basic attributes:</p>
<ul class="simple">
<li><p>Position</p></li>
<li><p>Size</p></li>
<li><p>Parent</p></li>
<li><p>Styles</p></li>
<li><p>Event handlers</p></li>
<li><p>Etc</p></li>
</ul>
<p>You can set/get these attributes with <code class="docutils literal notranslate"><span class="pre">lv_obj_set_...</span></code> and
<code class="docutils literal notranslate"><span class="pre">lv_obj_get_...</span></code> functions. For example:</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span><span class="cm">/*Set basic object attributes*/</span>
<span class="n">lv_obj_set_size</span><span class="p">(</span><span class="n">btn1</span><span class="p">,</span><span class="w"> </span><span class="mi">100</span><span class="p">,</span><span class="w"> </span><span class="mi">50</span><span class="p">);</span><span class="w"> </span><span class="cm">/*Set a button&#39;s size*/</span>
<span class="n">lv_obj_set_pos</span><span class="p">(</span><span class="n">btn1</span><span class="p">,</span><span class="w"> </span><span class="mi">20</span><span class="p">,</span><span class="mi">30</span><span class="p">);</span><span class="w"> </span><span class="cm">/*Set a button&#39;s position*/</span>
</pre></div>
</div>
<p>To see all the available functions visit the <a class="reference external" href="/widgets/obj">Base object's documentation</a>.</p>
</section>
<section id="specific-attributes">
<h3>Specific attributes<a class="headerlink" href="#specific-attributes" title="Link to this heading"></a></h3>
<p>The object types have special attributes too. For example, a slider has</p>
<ul class="simple">
<li><p>Minimum and maximum values</p></li>
<li><p>Current value</p></li>
</ul>
<p>For these special attributes, every object type may have unique API
functions. For example for a slider:</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span><span class="cm">/*Set slider specific attributes*/</span>
<span class="n">lv_slider_set_range</span><span class="p">(</span><span class="n">slider1</span><span class="p">,</span><span class="w"> </span><span class="mi">0</span><span class="p">,</span><span class="w"> </span><span class="mi">100</span><span class="p">);</span><span class="w"> </span><span class="cm">/*Set the min. and max. values*/</span>
<span class="n">lv_slider_set_value</span><span class="p">(</span><span class="n">slider1</span><span class="p">,</span><span class="w"> </span><span class="mi">40</span><span class="p">,</span><span class="w"> </span><span class="n">LV_ANIM_ON</span><span class="p">);</span><span class="w"> </span><span class="cm">/*Set the current value (position)*/</span>
</pre></div>
</div>
<p>The API of the widgets is described in their
<a class="reference external" href="/widgets/index">Documentation</a> but you can also check the respective
header files (e.g. <em>widgets/lv_slider.h</em>)</p>

<h2>Working mechanisms<a class="headerlink" href="#working-mechanisms" title="Link to this heading"></a></h2>
<section id="parent-child-structure">
<h3>Parent-child structure<a class="headerlink" href="#parent-child-structure" title="Link to this heading"></a></h3>
<p>A parent object can be considered as the container of its children.
Every object has exactly one parent object (except screens), but a
parent can have any number of children. There is no limitation for the
type of the parent but there are objects which are typically a parent
(e.g. button) or a child (e.g. label).</p>
</section>
<section id="moving-together">
<h3>Moving together<a class="headerlink" href="#moving-together" title="Link to this heading"></a></h3>
<p>If the position of a parent changes, the children will move along with
it. Therefore, all positions are relative to the parent.</p>

<section id="create-and-delete-objects">
<h3>Create and delete objects<a class="headerlink" href="#create-and-delete-objects" title="Link to this heading"></a></h3>
<p>In LVGL, objects can be created and deleted dynamically at run time. It
means only the currently created (existing) objects consume RAM.</p>
<p>This allows for the creation of a screen just when a button is clicked
to open it, and for deletion of screens when a new screen is loaded.</p>
<p>UIs can be created based on the current environment of the device. For
example one can create meters, charts, bars and sliders based on the
currently attached sensors.</p>
<p>Every widget has its own <strong>create</strong> function with a prototype like this:</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span><span class="n">lv_obj_t</span><span class="w"> </span><span class="o">*</span><span class="w"> </span><span class="n">lv_</span><span class="o">&lt;</span><span class="n">widget</span><span class="o">&gt;</span><span class="n">_create</span><span class="p">(</span><span class="n">lv_obj_t</span><span class="w"> </span><span class="o">*</span><span class="w"> </span><span class="n">parent</span><span class="p">,</span><span class="w"> </span><span class="o">&lt;</span><span class="n">other</span><span class="w"> </span><span class="n">parameters</span><span class="w"> </span><span class="k">if</span><span class="w"> </span><span class="n">any</span><span class="o">&gt;</span><span class="p">);</span>
</pre></div>
</div>
<p>Typically, the create functions only have a <em>parent</em> parameter telling
them on which object to create the new widget.</p>
<p>The return value is a pointer to the created object with <a class="reference internal" href="../API/core/lv_obj.html#_CPPv48lv_obj_t" title="lv_obj_t"><code class="xref cpp cpp-type docutils literal notranslate"><span class="pre">lv_obj_t</span></code></a> <code class="docutils literal notranslate"><span class="pre">*</span></code>
type.</p>
<p>There is a common <strong>delete</strong> function for all object types. It deletes
the object and all of its children.</p>
<div class="highlight-c notranslate"><div class="highlight"><pre><span></span><span class="kt">void</span><span class="w"> </span><span class="nf">lv_obj_delete</span><span class="p">(</span><span class="n">lv_obj_t</span><span class="w"> </span><span class="o">*</span><span class="w"> </span><span class="n">obj</span><span class="p">);</span>
</pre></div>
</div>
<p><code class="xref cpp cpp-func docutils literal notranslate"><span class="pre">lv_obj_del()</span></code> will delete the object immediately. If for any reason you
can't delete the object immediately you can use
<span class="cpp-expr sig sig-inline cpp"><a class="reference internal" href="../API/core/lv_obj_tree.html#_CPPv419lv_obj_delete_asyncP9_lv_obj_t" title="lv_obj_delete_async"><span class="n">lv_obj_delete_async</span></a><span class="p">(</span><span class="n">obj</span><span class="p">)</span></span> which will perform the deletion on the next
call of <code class="xref cpp cpp-func docutils literal notranslate"><span class="pre">lv_timer_handler()</span></code>. This is useful e.g. if you want to
delete the parent of an object in the child's <a class="reference internal" href="../API/misc/lv_event.html#_CPPv4N15lv_event_code_t15LV_EVENT_DELETEE" title="LV_EVENT_DELETE"><code class="xref cpp cpp-enumerator docutils literal notranslate"><span class="pre">LV_EVENT_DELETE</span></code></a>
handler.</p>
<p>You can remove all the children of an object (but not the object itself)
using <span class="cpp-expr sig sig-inline cpp"><a class="reference internal" href="../API/core/lv_obj_tree.html#_CPPv412lv_obj_cleanP9_lv_obj_t" title="lv_obj_clean"><span class="n">lv_obj_clean</span></a><span class="p">(</span><span class="n">obj</span><span class="p">)</span></span>.</p>

<p>The states are usually automatically changed by the library as the user
interacts with an object (presses, releases, focuses, etc.). However,
the states can be changed manually too. To set or clear given state (but
leave the other states untouched) use
<code class="docutils literal notranslate"><span class="pre">lv_obj_add/remove_state(obj,</span> <span class="pre">LV_STATE_...)</span></code> In both cases OR-ed state
values can be used as well. E.g.
<span class="cpp-expr sig sig-inline cpp"><a class="reference internal" href="../API/core/lv_obj.html#_CPPv416lv_obj_add_stateP8lv_obj_t10lv_state_t" title="lv_obj_add_state"><span class="n">lv_obj_add_state</span></a><span class="p">(</span><span class="n">obj</span><span class="p">,</span><span class="w"> </span><span class="n">part</span><span class="p">,</span><span class="w"> </span><a class="reference internal" href="../API/core/lv_obj.html#_CPPv4N11_lv_state_t16LV_STATE_PRESSEDE" title="LV_STATE_PRESSED"><span class="n">LV_STATE_PRESSED</span></a><span class="w"> </span><span class="o">|</span><span class="w"> </span><span class="n">LV_PRESSED_CHECKED</span><span class="p">)</span></span>.</p>
