bell(displayof=0)

Ring a display’s bell.

bind(sequence=None, func=None, add=None)

Bind to this widget at event SEQUENCE a call to function FUNC.

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.

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.

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.

Bind will return an identifier to allow deletion of the bound function with unbind without memory leak.

If FUNC or SEQUENCE is omitted the bound function or list of bound events are returned.

bind_all(sequence=None, func=None, add=None)

Bind to all widgets at an event SEQUENCE a call to function FUNC. 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. See bind for the return value.

bind_class(className, sequence=None, func=None, add=None)

Bind to widgets with bindtag CLASSNAME at event SEQUENCE a call of function FUNC. 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. See bind for the return value.

bindtags(tagList=None)

Set or get the list of bindtags for this widget.

With no argument return the list of all bindtags associated with this widget. With a list of strings as argument the bindtags are set to this list. The bindtags determine in which order events are processed (see bind).
