window. It is useful since it allows you to catch events for widgets which
do not have their own window.

Methods
|
|
|
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.

|
|
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.
