<p>Bind to this widget at event SEQUENCE a call to function FUNC.</p>
<p>SEQUENCE is a string of concatenated event patterns. An event pattern
is of the form <MODIFIER-MODIFIER-TYPE-DETAIL> where MODIFIER is
one of Control, Mod2, M2, Shift, Mod3, M3, Lock, Mod4, M4, Button1, B1,
Mod5, M5 Button2, B2, Meta, M, Button3, B3, Alt, Button4, B4, Double,
Button5, B5 Triple, Mod1, M1. TYPE is one of Activate, Enter, Map,
ButtonPress, Button, Expose, Motion, ButtonRelease FocusIn, MouseWheel,
Circulate, FocusOut, Property, Colormap, Gravity Reparent, Configure,
KeyPress, Key, Unmap, Deactivate, KeyRelease Visibility, Destroy, Leave
and DETAIL is the button number for ButtonPress, ButtonRelease and DETAIL
is the Keysym for KeyPress and KeyRelease. Examples are
<Control-Button-1> for pressing Control and mouse button 1 or
<Alt-A> for pressing A and the Alt key (KeyPress can be omitted).
An event pattern can also be a virtual event of the form
<<AString>> where AString can be arbitrary. This event can be
generated by event_generate. If events are concatenated they must appear
shortly after each other.</p>
<p>FUNC will be called if the event sequence occurs with an instance of
Event as argument. If the return value of FUNC is "break" no
further bound function is invoked.</p>
<p>An additional boolean parameter ADD specifies whether FUNC will be
called additionally to the other bound function or whether it will
replace the previous function.</p>
<p>Bind will return an identifier to allow deletion of the bound function
with unbind without memory leak.</p>
<p>If FUNC or SEQUENCE is omitted the bound function or list of bound
events are returned.</p>
