Description
Re-export the operations of the chosen raw frontend (determined at compile time with cabal flags).
- data FrontendSession
- startup :: String -> (FrontendSession -> IO ()) -> IO ()
- frontendName :: String
- nextEvent :: FrontendSession -> Maybe Bool -> IO (Key, Modifier)
- promptGetAnyKey :: FrontendSession -> SingleFrame -> IO (Key, Modifier)
- display :: FrontendSession -> Bool -> Bool -> Maybe SingleFrame -> IO ()
Re-exported raw frontend
data FrontendSession Source
Session data maintained by the frontend.
startup :: String -> (FrontendSession -> IO ()) -> IO ()Source
Spawns the gtk input and output thread, which spawns all the other
required threads. We create a separate thread for gtk to minimize
communication with the heavy main thread. The other threads have to be
spawned after gtk is initialized, because they call postGUIAsync,
and need sview and stags.
The name of the frontend.
nextEvent :: FrontendSession -> Maybe Bool -> IO (Key, Modifier)Source
Input key via the frontend. Fail if there is no frame to show to the player as a prompt for the keypress.
promptGetAnyKey :: FrontendSession -> SingleFrame -> IO (Key, Modifier)Source
Display a prompt, wait for any key. Starts in Push or None mode, stop in None mode. Spends most time waiting for a key, so not performance critical, so does not need optimization.
display :: FrontendSession -> Bool -> Bool -> Maybe SingleFrame -> IO ()Source
Add a frame to be drawn.
