|
||||
* This function calls g_type_init() for you. gtk_init() is called
|
||||
* as soon as the application gets registered as the primary instance.
|
||||
*
|
||||
* Note that commandline arguments are not passed to gtk_init().
|
||||
* All GTK+ functionality that is available via commandline arguments
|
||||
* can also be achieved by setting suitable environment variables
|
||||
* such as <envvar>G_DEBUG</envvar>, so this should not be a big
|
||||
* problem. If you absolutely must support GTK+ commandline arguments,
|
||||
* you can explicitly call gtk_init() before creating the application
|
||||
* instance.
|
||||
*
|
||||
* The application id must be valid. See g_application_id_is_valid().
|
||||
*
|
||||
* Returns: a new #GtkApplication instance
