[−][src]Struct lv2_sys::LV2UI_Port_Map
Feature to map port symbols to UIs.
This can be used by the UI to get the index for a port with the given symbol. This makes it possible to implement and distribute a UI separately from the plugin (since symbol, unlike index, is a stable port identifier).
Fields
handle: LV2UI_Feature_Handle
Pointer to opaque data which must be passed to port_index().
port_index: Option<unsafe extern "C" fn(handle: LV2UI_Feature_Handle, symbol: *const c_char) -> u32>
Get the index for the port with the given symbol
.
@return The index of the port, or LV2UI_INVALID_PORT_INDEX if no such port is found.
