bind :: (GUIObject wid) => wid -> [WishEvent] -> IO (Event EventInfo, IO ())

Binds an event for this widget. The second action returned unbinds the event.

bindSimple :: (GUIObject wid) => wid -> WishEventType -> IO (Event (), IO ())

Simple version of bind for only one event and without modifiers.

class (GUIObject w) => HasCommand w where

Methods clicked :: w -> IO (Event ()) Instances HasCommand Button HasCommand (CheckButton a) HasCommand MenuButton HasCommand MenuCheckButton HasCommand MenuCommand HasCommand MenuRadioButton HasCommand (RadioButton a)

delayWish :: IO a -> IO a

delayWish does an action, with the proviso that wish commands executed within the action by this or any other thread may be delayed. This can (allegedly) be faster.

initHTk

:: [Config HTk] the list of configuration options for the wish instance / main window. -> IO HTk The wish instance. Initializes HTk.

withdrawMainWin :: Config HTk

Withdraws the main window.

finishHTk :: IO ()

withdrawWish :: IO ()

data HTk

The HTk datatype - a handle for the wish instance and the main window.

data AbstractWidget

Constructors NONE Instances GUIObject AbstractWidget Container AbstractWidget

updateAllTasks :: IO ()

Updates all tasks.

updateIdleTasks :: IO ()

Updates idle tasks.
