Declaration [src]

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.



Type: const char*

The application ID.

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

Type: GApplicationFlags

The application flags.

Return value

Type: GtkApplication

A new GtkApplication instance.

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