data Event w a

An event for a widget w that expects an event handler of type a.

on :: Event w a -> Attr w a

Transform an event to an attribute.

mapEvent :: (a -> b) -> (a -> b -> a) -> Event w a -> Event w b

Change the event type.

class Selecting w where

Selecting widgets fire a select event when an item is selected.

Methods

select :: Event w (IO ())

A select event is fired when an item is selected.

select :: Selecting w => Event w (IO ())

A select event is fired when an item is selected.

class Commanding w where

Commanding widgets fire a command event.

Methods

command :: Event w (IO ())

A commanding event, for example a button press.

show/hide

Instances

Commanding ToolBarItem

command :: Commanding w => Event w (IO ())

A commanding event, for example a button press.

class Reactive w where

Reactive widgets are almost all visible widgets on the screen.

Methods

mouse :: Event w (EventMouse -> IO ())

keyboard :: Event w (EventKey -> IO ())

closing :: Event w (IO ())

idle :: Event w (IO Bool)

resize :: Event w (IO ())

focus :: Event w (Bool -> IO ())

mouse :: Reactive w => Event w (EventMouse -> IO ())

keyboard :: Reactive w => Event w (EventKey -> IO ())

closing :: Reactive w => Event w (IO ())

idle :: Reactive w => Event w (IO Bool)

resize :: Reactive w => Event w (IO ())

focus :: Reactive w => Event w (Bool -> IO ())

activate :: Reactive w => Event w (Bool -> IO ())

class Paint w where

Paint widgets can serve as a canvas. Note: it is illegal to use both a paint and paintRaw event handler at the same widget.

Methods

paint :: Event w (DC () -> Rect -> IO ())

Paint double buffered to a device context. The context is always cleared before drawing. Takes the current view rectangle (adjusted for scrolling) as an argument.

paintRaw :: Event w (DC () -> Rect -> [Rect] -> IO ())

Paint directly to the on-screen device context. Takes the current view rectangle and a list of dirty rectangles as arguments.\

repaint :: w -> IO ()

Emit a paint event to the specified widget.

paint :: Paint w => Event w (DC () -> Rect -> IO ())

Paint double buffered to a device context. The context is always cleared before drawing. Takes the current view rectangle (adjusted for scrolling) as an argument.

paintRaw :: Paint w => Event w (DC () -> Rect -> [Rect] -> IO ())

Paint directly to the on-screen device context. Takes the current view rectangle and a list of dirty rectangles as arguments.\

repaint :: Paint w => w -> IO ()

Emit a paint event to the specified widget.

enter :: Reactive w => Event w (Point -> IO ())

leave :: Reactive w => Event w (Point -> IO ())

motion :: Reactive w => Event w (Point -> IO ())

drag :: Reactive w => Event w (Point -> IO ())

click :: Reactive w => Event w (Point -> IO ())

unclick :: Reactive w => Event w (Point -> IO ())

doubleClick :: Reactive w => Event w (Point -> IO ())

clickRight :: Reactive w => Event w (Point -> IO ())

unclickRight :: Reactive w => Event w (Point -> IO ())

calendarEvent :: Event (CalendarCtrl a) (EventCalendar -> IO ())

Keyboard events

newEvent :: String -> (w -> IO a) -> (w -> a -> IO ()) -> Event w a

Create a new event from a get and set function.
