<p><em>Browser Window</em> needs to be initialized, and also run its own runtime.
Once that is set up and running, all windows can be constructed and be used.
To do this, use <code>Application::initialize</code>.
Then you will have an <code>Application</code> instance, from which you can derive a <code>Runtime</code> instance.
Running the <code>Runtime</code> will grant you access to an <code>ApplicationHandle</code> which you use to manipulate your application with.</p>
<h1 id="example-1" class="section-header"><a href="#example-1">Example #1</a></h1>
<p>Here is an example to show how you can construct your application:</p>
<div class="example-wrap"><pre class="rust rust-example-rendered">
<span class="kw">use</span> <span class="ident">browser_window</span>::<span class="ident">application</span>::<span class="kw-2">*</span>;
<span class="kw">fn</span> <span class="ident">main</span>() {
<span class="kw">let</span> <span class="ident">application</span> <span class="op">=</span> <span class="ident">Application</span>::<span class="ident">initialize</span>( <span class="ident">ApplicationSettings</span>::<span class="ident">default</span>() );
<span class="kw">let</span> <span class="ident">runtime</span> <span class="op">=</span> <span class="ident">application</span>.<span class="ident">start</span>();
<span class="ident">runtime</span>.<span class="ident">run_async</span>(<span class="op">|</span><span class="ident">handle</span><span class="op">|</span> <span class="ident">async</span> <span class="kw">move</span> {
<span class="comment">// Do something ...</span>
});
}</pre></div>
<h1 id="example-2" class="section-header"><a href="#example-2">Example #2</a></h1>
<p>If you want to run another kind of runtime, like <a href="https://tokio.rs/">tokio</a> for example, its still possible to use <em>Browser Window</em> in conjunction with that.
However, you will need to enable feature <code>threadsafe</code>, as it will enable all threadsafe handles.
Here is an example:</p>
<div class="example-wrap"><pre class="rust rust-example-rendered">
<span class="kw">use</span> <span class="ident">browser_window</span>::<span class="ident">application</span>::<span class="kw-2">*</span>;
<span class="kw">use</span> <span class="ident">tokio</span>;
<span class="ident">async</span> <span class="kw">fn</span> <span class="ident">async_main</span>( <span class="ident">app</span>: <span class="ident">ApplicationHandleThreaded</span> ) {
<span class="comment">// Do something ...</span>
}
<span class="kw">fn</span> <span class="ident">main</span>() {
<span class="kw">let</span> <span class="ident">application</span> <span class="op">=</span> <span class="ident">Application</span>::<span class="ident">initialize</span>( <span class="ident">ApplicationSettings</span>::<span class="ident">default</span>() );
<span class="kw">let</span> <span class="ident">bw_runtime</span> <span class="op">=</span> <span class="ident">application</span>.<span class="ident">start</span>();
<span class="kw">let</span> <span class="ident">tokio_runtime</span> <span class="op">=</span> <span class="ident">tokio</span>::<span class="ident">runtime</span>::<span class="ident">Runtime</span>::<span class="ident">new</span>().<span class="ident">unwrap</span>();
<span class="comment">// First run our own runtime on the main thread</span>
<span class="ident">bw_runtime</span>.<span class="ident">run</span>(<span class="op">|</span><span class="ident">_app</span><span class="op">|</span> {

<span class="comment">// Spawn the main logic into the tokio runtime</span>
<span class="ident">tokio_runtime</span>.<span class="ident">spawn</span>( <span class="ident">async_main</span>( <span class="ident">app</span> ) );
