<a name="line-40"></a><span class='hs-comment'>--</span>
<a name="line-41"></a><span class='hs-comment'>-- | This modules provides a monad that encapsulates the information in an</span>
<a name="line-42"></a><span class='hs-comment'>-- event.</span>
<a name="line-43"></a><span class='hs-comment'>--</span>
<a name="line-44"></a><span class='hs-comment'>-- The events a widget can receive are defined in</span>
<a name="line-45"></a><span class='hs-comment'>-- "Graphics.UI.Gtk.Abstract.Widget#7". Every event carries additional</span>
<a name="line-46"></a><span class='hs-comment'>-- information which is accessible through functions in the 'EventM' monad.</span>
<a name="line-47"></a><span class='hs-comment'>-- For instance, every event is associated with a</span>
<a name="line-48"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.Gdk.DrawWindow.DrawWindow' which is accessed using the</span>
<a name="line-49"></a><span class='hs-comment'>-- 'eventWindow' accessor function. Other information is only available in</span>
<a name="line-50"></a><span class='hs-comment'>-- one specific event. For example, the</span>
<a name="line-51"></a><span class='hs-comment'>-- area that has to be redrawn, accessed by 'eventArea' is only available in</span>
<a name="line-52"></a><span class='hs-comment'>-- the 'Graphics.UI.Gtk.Abstract.Widget.exposeEvent'. Indeed, you can only</span>
<a name="line-53"></a><span class='hs-comment'>-- call 'eventArea' if the first type parameter of 'EventM' is the phantom</span>
<a name="line-54"></a><span class='hs-comment'>-- type 'EExpose'. (A phantom type is a type for which no values exist and</span>
<a name="line-55"></a><span class='hs-comment'>-- which is only used to enforce certain constraints on the usage of</span>
<a name="line-56"></a><span class='hs-comment'>-- functions such as 'eventArea'.) Some information is available in several</span>
<a name="line-57"></a><span class='hs-comment'>-- but not all events. In order to express these constraints the module</span>
<a name="line-58"></a><span class='hs-comment'>-- defines type classes whose names start with @Has...@ but which are not</span>
<a name="line-59"></a><span class='hs-comment'>-- exported, implying that no new instance can be created. (They could be</span>
<a name="line-60"></a><span class='hs-comment'>-- called phantom type classes.) For instance, the mouse pointer coordinates</span>
<a name="line-61"></a><span class='hs-comment'>-- can be retrieved using the function 'eventCoordinates' which requires</span>
<a name="line-62"></a><span class='hs-comment'>-- that the first type parameter of 'EventM' is in the class</span>
<a name="line-63"></a><span class='hs-comment'>-- 'HasCoordinates'. The module supplies instance of class 'HasCoordinates'</span>
<a name="line-64"></a><span class='hs-comment'>-- for the types 'EButton', 'ECrossing', 'EMotion' and 'EScroll'. Thus for</span>
<a name="line-65"></a><span class='hs-comment'>-- all events that require an 'EventM' action with one of the types above,</span>
<a name="line-66"></a><span class='hs-comment'>-- the accessor function 'eventCoordinates' may be used.</span>
<a name="line-67"></a><span class='hs-comment'>--</span>
<a name="line-68"></a><span class='hs-comment'>-- Note that an event handler must always returns @True@ if the event</span>
<a name="line-69"></a><span class='hs-comment'>-- was handled or @False@ if the event should be dealt with by another</span>
<a name="line-70"></a><span class='hs-comment'>-- event handler. For instance, a handler for a key press should return</span>
<a name="line-71"></a><span class='hs-comment'>-- @False@ if the pressed key is not one of those that the widget reacts</span>
<a name="line-72"></a><span class='hs-comment'>-- to. In this case the event is passed to the parent widgets. This</span>
<a name="line-73"></a><span class='hs-comment'>-- ensures that pressing, say, @Alt-F@ opens the file menu even if the</span>
<a name="line-74"></a><span class='hs-comment'>-- current input focus is in a text entry widget. In order to facilitate</span>
<a name="line-75"></a><span class='hs-comment'>-- writing handlers that may abort handling an event, this module provides</span>
<a name="line-76"></a><span class='hs-comment'>-- the function 'tryEvent'. This function catches pattern match exceptions</span>
<a name="line-77"></a><span class='hs-comment'>-- and returns @False@. If the signal successfully runs to its end, it</span>
<a name="line-78"></a><span class='hs-comment'>-- returns @True@. A typical use is as follows:</span>
<a name="line-79"></a><span class='hs-comment'>--</span>
<a name="line-80"></a><span class='hs-comment'>-- > widget `on` keyPressEvent $ tryEvent $ do</span>
<a name="line-81"></a><span class='hs-comment'>-- > [Control] <- eventModifier</span>
<a name="line-82"></a><span class='hs-comment'>-- > "Return" <- eventKeyName</span>
<a name="line-83"></a><span class='hs-comment'>-- > liftIO $ putStrLn "Ctrl-Return pressed"</span>
<a name="line-84"></a><span class='hs-comment'>--</span>
<a name="line-85"></a><span class='hs-comment'>-- The rationale is that the action will throw an exception if the</span>
<a name="line-86"></a><span class='hs-comment'>-- two event functions 'eventModifier' and 'eventKeyName' return something</span>
<a name="line-87"></a><span class='hs-comment'>-- else than what is stated in</span>
<a name="line-88"></a><span class='hs-comment'>-- the pattern. When no exception is thrown, execution continues to</span>
<a name="line-89"></a><span class='hs-comment'>-- the last statement where the event is processed, here we merely</span>
<a name="line-90"></a><span class='hs-comment'>-- print a message. Note that the return</span>
<a name="line-91"></a><span class='hs-comment'>-- value of this statement must be @()@ since 'tryEvent' always</span>
<a name="line-92"></a><span class='hs-comment'>-- assumes that the</span>
<a name="line-93"></a><span class='hs-comment'>-- function handeled the event if no exception is thrown. A handler</span>
<a name="line-94"></a><span class='hs-comment'>-- wrapped by 'tryEvent' can also indicate that it cannot handle the</span>
<a name="line-95"></a><span class='hs-comment'>-- given event by calling 'stopEvent'.</span>
<a name="line-96"></a><span class='hs-comment'>--</span>
<a name="line-97"></a><span class='hs-comment'>-- Finally, not that the 'EventM' monad wraps the @IO@ monad. As such</span>
<a name="line-98"></a><span class='hs-comment'>-- you can (and usually have to) use @liftIO@ to execute @IO@ functions.</span>
