|A widget used to catch events for widgets which do not have their own window|
|The EventBox widget is a subclass of Bin which also has its own window. It is useful since it allows you to catch events for widgets which do not have their own window.|
|class BinClass o => EventBoxClass o|
|castToEventBox :: GObjectClass obj => obj -> EventBox|
|toEventBox :: EventBoxClass o => o -> EventBox|
|eventBoxNew :: IO EventBox|
|Creates a new EventBox.|
|eventBoxSetVisibleWindow :: EventBox -> Bool -> IO ()|
Set whether the event box uses a visible or invisible child window. The default is to use visible windows.
In an invisible window event box, the window that that the event box creates is a "input only" window, which means that it is invisible and only serves to receive events.
A visible window event box creates a visible ("input output") window that acts as the parent window for all the widgets contained in the event box.
You should generally make your event box invisible if you just want to trap events. Creating a visible window may cause artifacts that are visible to the user, especially if the user is using a theme with gradients or pixmaps.
The main reason to create a non input-only event box is if you want to set the background to a different color or draw on it.
|eventBoxGetVisibleWindow :: EventBox -> IO Bool|
Returns whether the event box has a visible window. See eventBoxSetVisibleWindow for details.
|eventBoxSetAboveChild :: EventBox -> Bool -> IO ()|
Set whether the event box window is positioned above the windows of its child, as opposed to below it. If the window is above, all events inside the event box will go to the event box. If the window is below, events in windows of child widgets will first got to that widget, and then to its parents.
The default is to keep the window below the child.
|eventBoxGetAboveChild :: EventBox -> IO Bool|
Returns whether the event box window is above or below the windows of its child. See eventBoxSetAboveChild for details.
|eventBoxVisibleWindow :: Attr EventBox Bool|
Whether the event box is visible, as opposed to invisible and only used to trap events.
Default value: True
|eventBoxAboveChild :: Attr EventBox Bool|
Whether the event-trapping window of the eventbox is above the window of the child widget as opposed to below it.
Default value: False
