Description

The GtkEventBox is used to capture events for widgets that do not have their own window.

Most widgets inherit the window property from GtkWidget, which makes it possible to use those widgets interactively. However, some widgets are flagged as GTK_NO_WINDOW at source, because there is rarely a need to capture events crossing those widgets.

The following widgets and their descendants fall into this category and need to be packed into an event box before they can be made to respond to user activity:

GtkAlignment

GtkArrow

GtkBox

GtkCheckButton

GtkFrame

GtkImage

GtkItem

GtkLabel

GtkPacker

GtkPixmap

GtkScale

GtkScrolledWindow

GtkSeparator

GtkTable

GtkToggleButton - alters according to its draw indicator status!
