## Detailed Description

The Gtk::Application class handles many important aspects of a GTK+ application in a convenient fashion, without enforcing a one-size-fits-all application model.

Currently, Gtk::Application handles GTK+ and gtkmm 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 Gtk::Application works fine with plain Gtk::Windows, it is recommended to use it together with Gtk::ApplicationWindow.

When GDK threads are enabled, Gtk::Application 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 Gio::ActionGroup::activate_action(). The same applies to actions associated with Gtk::ApplicationWindow and to the Gio::Application::activate() and Gio::Application::open() methods.

To set an application menu for a Gtk::Application, use set_app_menu(). The Gio::MenuModel that this method expects is usually constructed using Gtk::Builder. To specify a menubar that will be shown by Gtk::ApplicationWindows, use set_menubar(). Use the base Gio::ActionMap interface to add actions, to respond to the user selecting these menu items.

GTK+ displays these menus as expected, depending on the platform the application is running on.

Gtk::Application optionally registers with a session manager of the users session (if you set the 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 inhibit() method. 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.

Since gtkmm 3.4:

## Constructor & Destructor Documentation

virtual Gtk::Application::~Application | ( |  | ) |

virtual

Reimplemented from Gio::Application.

Gtk::Application::Application | ( | const Glib::ustring & | application_id = `Glib::ustring()`,
|  | Gio::ApplicationFlags | flags = `Gio::APPLICATION_FLAGS_NONE`
| ) |  |

explicit protected

Creates a new Application instance.

This initializes gtkmm (and the GObject type system) for you.

If non-empty, the application ID must be valid. See g_application_id_is_valid().

If no application ID is given then some features (most notably application uniqueness) will be disabled. A null application ID is only allowed with gtkmm 3.6 or later.

Parameters

  application_id | A valid application ID.
  flags | The application flags.

Since gtkmm 3.4:

Gtk::Application::Application | ( | int & | argc,
|  | char **& | argv,
|  | const Glib::ustring & | application_id = `Glib::ustring()`,
|  | Gio::ApplicationFlags | flags = `Gio::APPLICATION_FLAGS_NONE`
| ) |  |

explicit protected

Creates a new Application instance.

This initializes gtkmm (and the GObject type system) for you, parsing the standard GTK+ command line arguments.

You could instead use the constuctor that takes no command line arguements and later supply the command line arguments to run().

Note that all GTK+ functionality that is available via command line arguments can instead be achieved by setting suitable environment variables such as G_DEBUG.

If non-empty, the application ID must be valid. See g_application_id_is_valid().

If no application ID is given then some features (most notably application uniqueness) will be disabled. A null application ID is only allowed with gtkmm 3.6 or later.

Parameters

  argc | The parameter received by your main() function.
  argv | The parameter received by your main() function.
  application_id | A valid application ID.
  flags | The application flags.

Since gtkmm 3.4:

## Member Function Documentation

void Gtk::Application::add_accelerator | ( | const Glib::ustring & | accelerator,
|  | const Glib::ustring & | action_name,
|  | GVariant * | parameter
| ) |  |

Installs an accelerator that will cause the named action to be activated when the key combination specificed by accelerator is pressed.

accelerator must be a string that can be parsed by gtk_accelerator_parse(), e.g. "<Primary>q" or "<Control><Alt>p".

action_name must be the name of an action as it would be used in the app menu, i.e. actions that have been added to the application are referred to with an "app." prefix, and window-specific actions with a "win." prefix.

GtkApplication also extracts accelerators out of 'accel' attributes in the MenuModels passed to set_app_menu() and set_menubar(), which is usually more convenient than calling this function for each accelerator.

Since gtkmm 3.4:

Parameters

  accelerator | Accelerator string.
  action_name | The name of the action to activate.
  parameter | Parameter to pass when activating the action, or `0` if the action does not accept an activation parameter.

void Gtk::Application::add_accelerator | ( | const Glib::ustring & | accelerator,
|  | const Glib::ustring & | action_name
| ) |  |

A add_accelerator() convenience overload.

void Gtk::Application::add_window | ( | Window& | window | ) |

Adds a window to the Gtk::Application.

If all the windows managed by Gtk::Application are closed or removed from the application then the Gtk::Application will call quit(), and quit the application.

This call is equivalent to calling Gtk::Window::set_application().

Normally, the connection between the application and the window will remain until the window is closed or destroyed, but you can explicitly remove it with remove_window().

Since gtkmm 3.4:

Parameters

  window | A toplevel window to add to the application.

static Glib::RefPtr<Application> Gtk::Application::create | ( | const Glib::ustring & | application_id = `Glib::ustring()`,
|  | Gio::ApplicationFlags | flags = `Gio::APPLICATION_FLAGS_NONE`
| ) |  |

static

Creates a new Application instance.

This initializes gtkmm (and the GObject type system) for you.

If non-empty, the application ID must be valid. See g_application_id_is_valid().

If no application ID is given then some features (most notably application uniqueness) will be disabled. A null application ID is only allowed with gtkmm 3.6 or later.

Parameters

  application_id | A valid application ID.
  flags | The application flags.

Since gtkmm 3.4:

static Glib::RefPtr<Application> Gtk::Application::create | ( | int & | argc,
|  | char **& | argv,
|  | const Glib::ustring & | application_id = `Glib::ustring()`,
|  | Gio::ApplicationFlags | flags = `Gio::APPLICATION_FLAGS_NONE`
| ) |  |

You could instead use the constuctor that takes no command line arguements and later supply the command line arguments to run().

Note that all GTK+ functionality that is available via command line arguments can instead be achieved by setting suitable environment variables such as G_DEBUG.

If non-empty, the application ID must be valid. See g_application_id_is_valid().

Since gtkmm 3.6:

Returns
  The active window.

const Window* Gtk::Application::get_active_window | ( |  | ) | const

Gets the "active" window for the application.

The active window is the one that was most recently focused (within the application). This window may not have the focus at the moment if another application has it – this is just the most recently-focused window within this application.

Since gtkmm 3.6:

Returns
  The active window.

Glib::RefPtr<Gio::MenuModel> Gtk::Application::get_app_menu | ( |  | ) |

Window* Gtk::Application::get_window_by_id | ( | guint | id | ) |

Returns the Gtk::ApplicationWindow with the given ID.

Since gtkmm 3.6:

Parameters

  id | An identifier number.

Returns
  The window with ID id, or `0` if there is no window with this ID.

const Window* Gtk::Application::get_window_by_id | ( | guint | id | ) | const

Returns the Gtk::ApplicationWindow with the given ID.

Since gtkmm 3.6:

Parameters

  id | An identifier number.

Returns
  The window with ID id, or `0` if there is no window with this ID.

std::vector<Window*> Gtk::Application::get_windows | ( |  | ) |

Gets a list of the Gtk::Windows associated with application.

The list is sorted by most recently focused window, such that the first element is the currently focused window. (Useful for choosing a parent for a transient window.)

The list that is returned should not be modified in any way. It will only remain valid until the next focus change or window creation or deletion.

Since gtkmm 3.0:

Returns
  A List of Gtk::Window.

std::vector<const Window*> Gtk::Application::get_windows | ( |  | ) | const

Gets a list of the Gtk::Windows associated with application.

The list is sorted by most recently focused window, such that the first element is the currently focused window. (Useful for choosing a parent for a transient window.)

The list that is returned should not be modified in any way. It will only remain valid until the next focus change or window creation or deletion.

Since gtkmm 3.0:

GtkApplication* Gtk::Application::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

const GtkApplication* Gtk::Application::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

GtkApplication* Gtk::Application::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

guint Gtk::Application::inhibit | ( | Window& | window,
|  | ApplicationInhibitFlags | flags,
|  | const Glib::ustring & | reason
| ) |  |

Inform the session manager that certain types of actions should be inhibited.

This is not guaranteed to work on all platforms and for all types of actions.

Applications should invoke this method when they begin an operation that should not be interrupted, such as creating a CD or DVD. The types of actions that may be blocked are specified by the flags parameter. When the application completes the operation it should call uninhibit() to remove the inhibitor. Note that an application can have multiple inhibitors, and all of the must be individually removed. Inhibitors are also cleared when the application exits.

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.

Reasons should be short and to the point.

If window is given, the session manager may point the user to this window to find out more about why the action is inhibited.

Since gtkmm 3.4:

Parameters

  window | A Gtk::Window, or `0`.
  flags | What types of actions should be inhibited.
  reason | A short, human-readable string that explains why these operations are inhibited.

Returns
  A non-zero cookie that is used to uniquely identify this request. It should be used as an argument to uninhibit() in order to remove the request. If the platform does not support inhibiting or the request failed for some reason, 0 is returned.

void Gtk::Application::remove_accelerator | ( | const Glib::ustring & | action_name,
|  | GVariant * | parameter
| ) |  |

Removes an accelerator that has been previously added with add_accelerator().

Since gtkmm 3.4:

Parameters

  action_name | The name of the action to activate.
  parameter | Parameter to pass when activating the action, or `0` if the action does not accept an activation parameter.

void Gtk::Application::remove_accelerator | ( | const Glib::ustring & | action_name | ) |

A remove_accelerator() convenience overload.

void Gtk::Application::remove_window | ( | Window& | window | ) |

Remove a window from application.

If window belongs to application then this call is equivalent to setting the Gtk::Window::property_application() property of window to `0`.

The application may stop running as a result of a call to this function.

Since gtkmm 3.0:

Parameters

  window | A Gtk::Window.

int Gtk::Application::run | ( | int | argc,
|  | char ** | argv
| ) |  |

Starts the application.

The default implementation of this virtual function will simply run a main loop.

It is an error to call this function if application is a proxy for a remote application.

Parameters

  argc | The argc from main() (or 0 if argv is `0`).
  argv | The argv from main(), or `0`.

Returns
  The exit status.

Since gtkmm 3.4:

int Gtk::Application::run | ( | Window& | window,
|  | int | argc,
|  | char ** | argv
| ) |  |

Starts the application.

The default implementation of this virtual function will simply run a main loop.

It is an error to call this function if application is a proxy for a remote application.

Parameters

  window | The window to show. This method will return when the window is hidden.
  argc | The argc from main() (or 0 if argv is `0`).
  argv | The argv from main(), or `0`.

Returns
  The exit status.

Since gtkmm 3.4:

int Gtk::Application::run | ( | Window& | window | ) |

Starts the application.

The default implementation of this virtual function will simply run a main loop.

It is an error to call this function if application is a proxy for a remote application.

Parameters

  window | The window to show. This method will return when the window is hidden.

Returns
  The exit status.

Since gtkmm 3.4:

int Gtk::Application::run | ( |  | ) |

Starts the application.

The default implementation of this virtual function will simply run a main loop.

It is an error to call this function if application is a proxy for a remote application.

Returns
  The exit status.

Since gtkmm 3.4:

void Gtk::Application::set_app_menu | ( | const Glib::RefPtr< Gio::MenuModel > & | app_menu | ) |

Sets or unsets the application menu for application.

This can only be done in the primary instance of the application, after it has been registered. Application::property_startup() is a good place to call this.

The application menu is a single menu containing items that typically impact the application as a whole, rather than acting on a specific window or document. For example, you would expect to see "Preferences" or "Quit" in an application menu, but not "Save" or "Print".

If supported, the application menu will be rendered by the desktop environment.

Use the base ActionMap interface to add actions, to respond to the user selecting these menu items.

Since gtkmm 3.4:

Parameters

  app_menu | A MenuModel, or `0`.

void Gtk::Application::set_menubar | ( | const Glib::RefPtr< Gio::MenuModel > & | menubar | ) |

Sets or unsets the menubar for windows of application.

This is a menubar in the traditional sense.

This can only be done in the primary instance of the application, after it has been registered. Application::property_startup() is a good place to call this.

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.

Use the base ActionMap interface to add actions, to respond to the user selecting these menu items.

Since gtkmm 3.4:

Parameters

  menubar | A MenuModel, or `0`.

Glib::SignalProxy1< void,Window* > Gtk::Application::signal_window_added | ( |  | ) |

Slot Prototype:
  `void on_my_window_added(Window* window)`

Emitted when a Gtk::Window is added to application through Gtk::Application::add_window().

Since gtkmm 3.2:

Parameters

  window | The newly-added Gtk::Window.

Glib::SignalProxy1< void,Window* > Gtk::Application::signal_window_removed | ( |  | ) |

Slot Prototype:
  `void on_my_window_removed(Window* window)`

Emitted when a Gtk::Window is removed from application, either as a side-effect of being destroyed or explicitly through Gtk::Application::remove_window().

Since gtkmm 3.2:

Parameters

  window | The Gtk::Window that is being removed.

void Gtk::Application::uninhibit | ( | guint | cookie | ) |

Removes an inhibitor that has been established with inhibit().

Inhibitors are also cleared when the application exits.

Since gtkmm 3.4:

Parameters

  cookie | A cookie that was returned by inhibit().
