Constructor

GtkApplicationnew

Declaration [src]

GtkApplication*
gtk_application_new (
  const char* application_id,
  GApplicationFlags flags
)

Description [src]

Creates a new GtkApplication instance.

When using GtkApplication, it is not necessary to call gtk_init() manually. It is called as soon as the application gets registered as the primary instance.

Concretely, gtk_init() is called in the default handler for the GApplication::startup signal. Therefore, GtkApplication subclasses should always chain up in their GApplication::startup handler before using any GTK API.

Note that commandline arguments are not passed to gtk_init().

If application_id is not NULL, then it 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.

Parameters

application_id const char*
 

The application ID.

 The argument can be NULL.
 The data is owned by the caller of the function.
 The string is a NUL terminated UTF-8 string.
flags GApplicationFlags
 

The application flags.

Return value

Returns: GtkApplication
 

A new GtkApplication instance.

 The caller of the function takes ownership of the data, and is responsible for freeing it.
