Since gtkmm 3.4:

## Constructor & Destructor Documentation

virtual Gtk::Application::~Application | ( |  | ) | `[virtual]`

Reimplemented from Gio::Application.

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

Creates a new Application instance.

This constructor calls g_type_init() for you. You should call run() with your main() function's argc and argv parameters to initialize gtkmm too.

Parameters:

  application_id | A valid application id
  flags | The application flags

Since gtkmm 3.4:

Reimplemented from Gio::Application.

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

Creates a new Application instance.

This constructor initializes gtkmm for you, so you should call run() without specifying the the argc and argv parameters again.

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_window | ( | Window& | window | ) |

Adds a window to the Gtk::Application.

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

If your application uses only a single toplevel window, you can use get_window(). If you are using a sub-class of Gtk::Application you should call create_window() to let the Gtk::Application instance create a Gtk::Window and add it to the list of toplevels of the application. You should call this function only to add Gtk::Windows that you created directly using new Gtk::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,
|  | Gio::ApplicationFlags | flags = `Gio::APPLICATION_FLAGS_NONE`
| ) |  | `[static]`

Reimplemented from Gio::Application.

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

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

Returns the menu model that has been set with set_app_menu().

Since gtkmm 3.4:

Returns:
  The application menu of application.

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

Returns the menu model that has been set with set_app_menu().

Since gtkmm 3.4:

Returns:
  The application menu of application.

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

Returns the menu model that has been set with set_menubar().

Returns:
  The menubar for windows of application.

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

Returns the menu model that has been set with set_menubar().

Since gtkmm 3.4:

Returns:
  The menubar for windows of application.

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:

Returns:
  A List of Gtk::Window.

GtkApplication* Gtk::Application::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::Application.

const GtkApplication* Gtk::Application::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GObject.

Reimplemented from Gio::Application.

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.

Reimplemented from Gio::Application.

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 Glib::application_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 Glib::application_uninhibit() in order to remove the request. If the platform does not support inhibiting or the request failed for some reason, 0 is returned.

bool Gtk::Application::is_inhibited | ( | ApplicationInhibitFlags | flags | ) | const

Determines if any of the actions specified in flags are currently inhibited (possibly by another application).

Since gtkmm 3.4:

Parameters:

  flags | What types of actions should be queried.

Returns:
  `true` if any of the actions specified in flags are inhibited.

virtual void Gtk::Application::on_window_added | ( | Window* | window | ) | `[protected, virtual]`

This is a default handler for the signal signal_window_added().

virtual void Gtk::Application::on_window_removed | ( | Window* | window | ) | `[protected, virtual]`

This is a default handler for the signal signal_window_removed().

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.

Since gtkmm 3.4:

Reimplemented from Gio::Application.

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.

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.

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.

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.

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.

You might call this method in your Application::property_startup() signal handler.

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.

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.

You might call this method in your Application::property_startup() signal handler.

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`.
