Typedef Documentation

vlc_dialog_cbs

typedef struct vlc_dialog_cbs vlc_dialog_cbs

Dialog callbacks to be implemented.

vlc_dialog_error_cbs

typedef void(* vlc_dialog_error_cbs) (void *p_data, const char *psz_title, const char *psz_text)

Called when an error message needs to be displayed.

Parameters

p_data	opaque pointer for the callback
psz_title	title of the dialog
psz_text	text of the dialog

Function Documentation

vlc_dialog_id_dismiss()

int vlc_dialog_id_dismiss

(

vlc_dialog_id *

p_id

)

Dismiss a dialog.

After this call, p_id won't be valid anymore

See also

vlc_dialog_cbs.pf_cancel

Parameters

p_id	id of the dialog

Returns

VLC_SUCCESS on success, or a VLC error code on error

References dialog_id_post().

vlc_dialog_id_get_context()

void * vlc_dialog_id_get_context

(

vlc_dialog_id *

p_id

)

Return the opaque pointer associated with the dialog id.

References vlc_dialog_id::lock, vlc_dialog_id::p_context, vlc_mutex_lock(), and vlc_mutex_unlock().

vlc_dialog_id_post_action()

int vlc_dialog_id_post_action	(	vlc_dialog_id *	p_id,
		int	i_action )

Post a question answer.

After this call, p_id won't be valid anymore

See also

vlc_dialog_cbs.pf_display_question

Parameters

p_id	id of the dialog
i_action	1 for action1, 2 for action2

Returns

VLC_SUCCESS on success, or a VLC error code on error

References dialog_id_post(), dialog_answer::i_action, and VLC_DIALOG_QUESTION.

vlc_dialog_id_post_login()

int vlc_dialog_id_post_login	(	vlc_dialog_id *	p_id,
		const char *	psz_username,
		const char *	psz_password,
		bool	b_store )

Post a login answer.

After this call, p_id won't be valid anymore

See also

vlc_dialog_cbs.pf_display_login

Parameters

p_id	id of the dialog
psz_username	valid and non empty string
psz_password	valid string (can be empty)
b_store	if true, store the credentials

Returns

VLC_SUCCESS on success, or a VLC error code on error

References dialog_answer::b_store, dialog_id_post(), dialog_answer::login, dialog_answer::psz_password, dialog_answer::psz_username, strdup(), dialog_answer::u, VLC_DIALOG_LOGIN, and VLC_ENOMEM.

vlc_dialog_id_set_context()

void vlc_dialog_id_set_context	(	vlc_dialog_id *	p_id,
		void *	p_context )

Associate an opaque pointer with the dialog id.

References vlc_dialog_id::lock, vlc_dialog_id::p_context, vlc_mutex_lock(), and vlc_mutex_unlock().

vlc_dialog_provider_set_callbacks()

void vlc_dialog_provider_set_callbacks	(	vlc_object_t *	p_obj,
		const vlc_dialog_cbs *	p_cbs,
		void *	p_data )

Register callbacks to handle VLC dialogs.

Parameters

p_obj	the VLC object to get the dialog provider from
p_cbs	a pointer to callbacks, or NULL to unregister callbacks.
p_data	opaque pointer for the callback

References vlc_dialog_provider::cbs, dialog_clear_all_locked(), get_dialog_provider(), vlc_dialog_provider::lock, vlc_dialog_provider::p_cbs_data, vlc_mutex_lock(), and vlc_mutex_unlock().

vlc_dialog_provider_set_error_callback()

void vlc_dialog_provider_set_error_callback	(	vlc_object_t *	p_obj,
		vlc_dialog_error_cbs	p_cbs,
		void *	p_data )

Register callbacks to handle VLC error messages.

Version

LibVLC 4.0.0 and later.

Parameters

p_obj	the VLC object to get the dialog provider from
p_cbs	a pointer to the callback, or NULL to unregister the callback.
p_data	opaque pointer for the callback
