static void app_widget_launch_audio ( void  )

static

Setup audio widget.

Allocates memory for the application context, and creates all widgets that make up its interface. If memory allocation or widget creation fails, the application exits immediately.

static bool widget_audio_command_handler ( struct wtk_basic_frame *  frame, win_command_t  command_data  )

static

Frame handler for the application.

Handles all command events from the widgets in the application frame.

Parameters

frame	Pointer to the application frame
command_data	Command event ID

Returns

True if exiting, to destroy the window
