<a name="GtkApplication.description"></a><h2>Description</h2>
<p><a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a> is a class that handles many important aspects
of a GTK+ application in a convenient fashion, without enforcing
a one-size-fits-all application model.</p>
<p>Currently, GtkApplication handles GTK+ initialization, application
uniqueness, session management, provides some basic scriptability and
desktop shell integration by exporting actions and menus and manages a
list of toplevel windows whose life-cycle is automatically tied to the
life-cycle of your application.</p>
<p>While GtkApplication works fine with plain <a href="GtkWindow.html#GtkWindow-struct"><span class="type">GtkWindows</span></a>, it is recommended
to use it together with <a class="link" href="GtkApplicationWindow.html" title="GtkApplicationWindow"><span class="type">GtkApplicationWindow</span></a>.</p>
<p>When GDK threads are enabled, GtkApplication will acquire the GDK
lock when invoking actions that arrive from other processes. The GDK
lock is not touched for local action invocations. In order to have
actions invoked in a predictable context it is therefore recommended
that the GDK lock be held while invoking actions locally with
<code class="function">g_action_group_activate_action()</code>. The same applies to actions
associated with <a class="link" href="GtkApplicationWindow.html" title="GtkApplicationWindow"><span class="type">GtkApplicationWindow</span></a> and to the “activate” and
“open” <span class="type">GApplication</span> methods.</p>
<div class="refsect3">
<a name="automatic-resources"></a><h4>Automatic resources</h4>
<p><a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a> will automatically load menus from the <a class="link" href="GtkBuilder.html" title="GtkBuilder"><span class="type">GtkBuilder</span></a>
resource located at "gtk/menus.ui", relative to the application's
resource base path (see <code class="function">g_application_set_resource_base_path()</code>). The
menu with the ID "app-menu" is taken as the application's app menu
and the menu with the ID "menubar" is taken as the application's
menubar. Additional menus (most interesting submenus) can be named
and accessed via <a class="link" href="GtkApplication.html#gtk-application-get-menu-by-id" title="gtk_application_get_menu_by_id ()"><code class="function">gtk_application_get_menu_by_id()</code></a> which allows for
dynamic population of a part of the menu structure.</p>
<p>If the resources "gtk/menus-appmenu.ui" or "gtk/menus-traditional.ui" are
present then these files will be used in preference, depending on the value
of <a class="link" href="GtkApplication.html#gtk-application-prefers-app-menu" title="gtk_application_prefers_app_menu ()"><code class="function">gtk_application_prefers_app_menu()</code></a>. If the resource "gtk/menus-common.ui"
is present it will be loaded as well. This is useful for storing items that
are referenced from both "gtk/menus-appmenu.ui" and
"gtk/menus-traditional.ui".</p>
<p>It is also possible to provide the menus manually using
<a class="link" href="GtkApplication.html#gtk-application-set-app-menu" title="gtk_application_set_app_menu ()"><code class="function">gtk_application_set_app_menu()</code></a> and <a class="link" href="GtkApplication.html#gtk-application-set-menubar" title="gtk_application_set_menubar ()"><code class="function">gtk_application_set_menubar()</code></a>.</p>
<p><a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a> will also automatically setup an icon search path for
the default icon theme by appending "icons" to the resource base
path. This allows your application to easily store its icons as
resources. See <a class="link" href="GtkIconTheme.html#gtk-icon-theme-add-resource-path" title="gtk_icon_theme_add_resource_path ()"><code class="function">gtk_icon_theme_add_resource_path()</code></a> for more
information.</p>
<p>If there is a resource located at "gtk/help-overlay.ui" which
defines a <a class="link" href="GtkShortcutsWindow.html" title="GtkShortcutsWindow"><span class="type">GtkShortcutsWindow</span></a> with ID "help_overlay" then GtkApplication
associates an instance of this shortcuts window with each
<a class="link" href="GtkApplicationWindow.html" title="GtkApplicationWindow"><span class="type">GtkApplicationWindow</span></a> and sets up keyboard accelerators (Control-F1
and Control-?) to open it. To create a menu item that displays the
shortcuts window, associate the item with the action win.show-help-overlay.</p>

<a name="gtkapplication"></a><h4>A simple application</h4>
<p><a class="ulink" href="https://git.gnome.org/browse/gtk+/tree/examples/bp/bloatpad.c" target="_top">A simple example</a></p>
<p>GtkApplication optionally registers with a session manager
of the users session (if you set the <a class="link" href="GtkApplication.html#GtkApplication--register-session" title="The “register-session” property"><span class="type">“register-session”</span></a>
property) and offers various functionality related to the session
life-cycle.</p>
<p>An application can block various ways to end the session with
the <a class="link" href="GtkApplication.html#gtk-application-inhibit" title="gtk_application_inhibit ()"><code class="function">gtk_application_inhibit()</code></a> function. Typical use cases for
this kind of inhibiting are long-running, uninterruptible operations,
such as burning a CD or performing a disk backup. The session
manager may not honor the inhibitor, but it can be expected to
inform the user about the negative consequences of ending the
session while inhibitors are present.</p>

<pre class="programlisting"><a class="link" href="GtkApplication.html" title="GtkApplication"><span class="returnvalue">GtkApplication</span></a> *
gtk_application_new (<em class="parameter"><code>const <span class="type">gchar</span> *application_id</code></em>,
<em class="parameter"><code><span class="type">GApplicationFlags</span> flags</code></em>);</pre>
<p>Creates a new <a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a> instance.</p>
<p>When using <a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a>, it is not necessary to call <a class="link" href="gtk3-General.html#gtk-init" title="gtk_init ()"><code class="function">gtk_init()</code></a>
manually. It is called as soon as the application gets registered as
the primary instance.</p>
<p>Concretely, <a class="link" href="gtk3-General.html#gtk-init" title="gtk_init ()"><code class="function">gtk_init()</code></a> is called in the default handler for the
<span class="type">“startup”</span> signal. Therefore, <a class="link" href="GtkApplication.html" title="GtkApplication"><span class="type">GtkApplication</span></a> subclasses should
chain up in their <span class="type">“startup”</span> handler before using any GTK+ API.</p>
<p>Note that commandline arguments are not passed to <a class="link" href="gtk3-General.html#gtk-init" title="gtk_init ()"><code class="function">gtk_init()</code></a>.
All GTK+ functionality that is available via commandline arguments
can also be achieved by setting suitable environment variables
such as <code class="literal">G_DEBUG</code>, so this should not be a big
problem. If you absolutely must support GTK+ commandline arguments,
you can explicitly call <a class="link" href="gtk3-General.html#gtk-init" title="gtk_init ()"><code class="function">gtk_init()</code></a> before creating the application
instance.</p>
<p>If non-<code class="literal">NULL</code>, the application ID must be valid. See
<code class="function">g_application_id_is_valid()</code>.</p>
<p>If no application ID is given then some features (most notably application
uniqueness) will be disabled. A null application ID is only allowed with
GTK+ 3.6 or later.</p>

<p>Adds a window to <em class="parameter"><code>application</code></em>

<p>This call can only happen after the <em class="parameter"><code>application</code></em>

typically, you should add new application windows in response

<p>This call is equivalent to setting the <a class="link" href="GtkWindow.html#GtkWindow--application" title="The “application” property"><span class="type">“application”</span></a>
property of <em class="parameter"><code>window</code></em>
to <em class="parameter"><code>application</code></em>

<p>Normally, the connection between the application and the window
will remain until the window is destroyed, but you can explicitly
remove it with <a class="link" href="GtkApplication.html#gtk-application-remove-window" title="gtk_application_remove_window ()"><code class="function">gtk_application_remove_window()</code></a>.</p>
<p>GTK+ will keep the <em class="parameter"><code>application</code></em>

<p>Applications should invoke this method when they begin an operation

types of actions that may be blocked are specified by the <em class="parameter"><code>flags</code></em>

an application can have multiple inhibitors, and all of them must

<p>Applications should not expect that they will always be able to block
the action. In most cases, users will be given the option to force
the action to take place.</p>

<p>Determines if the desktop environment in which the application is
running would prefer an application menu be shown.</p>
<p>If this function returns <code class="literal">TRUE</code> then the application should call
<a class="link" href="GtkApplication.html#gtk-application-set-app-menu" title="gtk_application_set_app_menu ()"><code class="function">gtk_application_set_app_menu()</code></a> with the contents of an application
menu, which will be shown by the desktop environment. If it returns
<code class="literal">FALSE</code> then you should consider using an alternate approach, such as
a menubar.</p>
<p>The value returned by this function is purely advisory and you are
free to ignore it. If you call <a class="link" href="GtkApplication.html#gtk-application-set-app-menu" title="gtk_application_set_app_menu ()"><code class="function">gtk_application_set_app_menu()</code></a> even
if the desktop environment doesn't support app menus, then a fallback
will be provided.</p>
<p>Applications are similarly free not to set an app menu even if the
desktop environment wants to show one. In that case, a fallback will
also be created by the desktop environment (GNOME, for example, uses
a menu with only a "Quit" item in it).</p>
<p>The value returned by this function never changes. Once it returns a
particular value, it is guaranteed to always return the same value.</p>
<p>You may only call this function after the application has been
registered and after the base startup handler has run. You're most
likely to want to use this from your own startup handler. It may
also make sense to consult this function while constructing UI (in
activate, open or an action activation handler) in order to determine
if you should show a gear menu or not.</p>
<p>This function will return <code class="literal">FALSE</code> on Mac OS and a default app menu
will be created automatically with the "usual" contents of that menu
typical to most Mac OS applications. If you call
<a class="link" href="GtkApplication.html#gtk-application-set-app-menu" title="gtk_application_set_app_menu ()"><code class="function">gtk_application_set_app_menu()</code></a> anyway, then this menu will be

<p>Sets or unsets the menubar for windows of <em class="parameter"><code>application</code></em>
.</p>
<p>This is a menubar in the traditional sense.</p>
<p>This can only be done in the primary instance of the application,
after it has been registered. <span class="type">“startup”</span> is a good place
to call this.</p>
<p>Depending on the desktop environment, this may appear at the top of
each window, or at the top of the screen. In some environments, if
both the application menu and the menubar are set, the application
menu will be presented as if it were the first item of the menubar.
Other environments treat the two as completely separate — for example,
the application menu may be rendered by the desktop shell while the
menubar (if set) remains in each individual window.</p>
<p>Use the base <span class="type">GActionMap</span> interface to add actions, to respond to the
user selecting these menu items.</p>

an accelerator editor or a plugin system, for example). Note that

<p>In case there are no actions for a given accelerator, an empty array
