These don't take a duration, instead they call g_get_monotonic_time() to and subtract the start time for it. Almost all our calls are like this, and this makes the callsites clearer and avoids inlining the clock call into the call site.

/**
|
|
* SECTION:gtkapplication
|
|
* @title: GtkApplication
|
|
* @short_description: Application class
|
|
*
|
|
* #GtkApplication 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.
|
|
*
|
|
* 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.
|
|
*
|
|
* While GtkApplication works fine with plain #GtkWindows, it is recommended
|
|
* to use it together with #GtkApplicationWindow.
|
|
*
|
|
* 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
|
|
* g_action_group_activate_action(). The same applies to actions
|
|
* associated with #GtkApplicationWindow and to the “activate” and
|
|
* “open” #GApplication methods.
|
|
*
|
|
* ## Automatic resources ## {#automatic-resources}
|
|
*
|
|
* #GtkApplication will automatically load menus from the #GtkBuilder
|
|
* resource located at "gtk/menus.ui", relative to the application's
|
|
* resource base path (see g_application_set_resource_base_path()). 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 gtk_application_get_menu_by_id() which allows for
|
|
* dynamic population of a part of the menu structure.
|
|
*
|
|
* 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 gtk_application_prefers_app_menu(). 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".
|
|
*
|
|
* It is also possible to provide the menus manually using
|
|
* gtk_application_set_app_menu() and gtk_application_set_menubar().
|
|
*
|
|
* #GtkApplication 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 gtk_icon_theme_add_resource_path() for more
|
|
* information.
|
|
*
|
|
* If there is a resource located at "gtk/help-overlay.ui" which
|
|
* defines a #GtkShortcutsWindow with ID "help_overlay" then GtkApplication
|
|
* associates an instance of this shortcuts window with each
|
|
* #GtkApplicationWindow and sets up the keyboard accelerator Control-?
|
|
* to open it. To create a menu item that displays the
|
|
* shortcuts window, associate the item with the action win.show-help-overlay.
|
|
*
|
|
* ## A simple application ## {#gtkapplication}
|
|
*
|
|
* [A simple example](https://gitlab.gnome.org/GNOME/gtk/tree/master/examples/bp/bloatpad.c)
|
|
*
|
|
* GtkApplication optionally registers with a session manager
|
|
* of the users session (if you set the #GtkApplication:register-session
|
|
* property) and offers various functionality related to the session
|
|
* life-cycle.
|
|
*
|
|
* An application can block various ways to end the session with
|
|
* the gtk_application_inhibit() 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.
|
|
*

|
* gtk_application_set_app_menu() with the contents of an application
|
|
* menu, which will be shown by the desktop environment. If it returns
|
|
* %FALSE then you should consider using an alternate approach, such as
|
|
* a menubar.
|
|
*
|
|
* The value returned by this function is purely advisory and you are
|
|
* free to ignore it. If you call gtk_application_set_app_menu() even
|
|
* if the desktop environment doesn't support app menus, then a fallback
|
|
* will be provided.
|
|
*
|
|
* 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).
|
|
*
|
|
* The value returned by this function never changes. Once it returns a
|
|
* particular value, it is guaranteed to always return the same value.
|
|
*
|
|
* 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.
|
|
*
|
|
* This function will return %FALSE 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
|
|
* gtk_application_set_app_menu() anyway, then this menu will be
|
|
* replaced with your own.
|
|
*
|
|
* Returns: %TRUE if you should set an app menu
