<p>In this example we will create an application to ask the user about his/her name.
When the user type the name in the textbox then click on “Say Hello” button, the textbox

<span id="index-2"></span><h2>The Events Loop<a class="headerlink" href="#the-events-loop" title="Permalink to this headline">¶</a></h2>
<p>Qt uses Event-Driven and the events loop get the control when we call the exec() method from the qApp class.</p>
<p>Once we call exec(), The events loop starts, and the Widgets starts responding to the different events (Mouse, Keyboard, Timers, etc).</p>
<p>You get the control back again when an event is fired and your callback function is called.</p>
<p>Once the execution of your callback function is done, the control go back again to the events loop.</p>
<p>Useful things to remember</p>
<ol class="arabic simple">
<li><p>We can do most of the work using normal events (Events provided directly by each widget).</p></li>
<li><p>We can add more events to any widget using the Events Filter.</p></li>
<li><p>Using Timers we can easily get the control back and check for more things to do.</p></li>
</ol>
<p>Also when our callback function is busy with doing time consuming operations, we can call the ProcessEvents() method from the qApp class
to avoid stoping the GUI.</p>

<p>We can avoid calling the exec() method, and create our main loop</p>

<p>Each Qt signal can be used in RingQt, just add Set before the signal name and add event after
the signal name to get the method that can be used to determine the event code.</p>
<p>For example the QProgressBar class contains a signal named valueChanged()
To use it just use the function setValueChangedEvent()</p>

<p>Qt Documentation : <a class="reference external" href="http://doc.qt.io/qt-5/classes.html">http://doc.qt.io/qt-5/classes.html</a></p>
<p>See the “RingQt Classes and Methods Reference” chapter for supported classes and methods.</p>

<span id="index-63"></span><h2>New Classes names - Index Start from 1<a class="headerlink" href="#new-classes-names-index-start-from-1" title="Permalink to this headline">¶</a></h2>
<p>We added new classes to RingQt - another version of classes where the class names doesn’t start with the “q” letter
Also updated methods so the index start from 1 when we deal with the GUI controls like</p>
<ul class="simple">
<li><p>ComboBox</p></li>
<li><p>ListWidget</p></li>
<li><p>TableWidget</p></li>
<li><p>TreeWidget</p></li>
</ul>
<p>These classes are inside guilib.ring under the package name : System.GUI</p>
<p>To use it</p>
<div class="highlight-ring notranslate"><div class="highlight"><pre><span></span><span class="k">load</span> <span class="s">&quot;guilib.ring&quot;</span>

<span class="k">import</span> <span class="n">System</span><span class="p">.</span><span class="n">GUI</span>
</pre></div>
</div>
<p>This doesn’t have any effect on our previous code, It’s just another choice for better code that is consistent with Ring rules.</p>
<p>Also the form designer is updated to provide us the choice between using classes where (index start from 0) or (index start from 1)</p>
<p>Example  (Uses the Form Designer)</p>
<ol class="arabic simple">
<li><p><a class="reference external" href="https://github.com/ring-lang/ring/blob/master/samples/UsingFormDesigner/indexstart/indexstartView.ring">https://github.com/ring-lang/ring/blob/master/samples/UsingFormDesigner/indexstart/indexstartView.ring</a></p></li>
