This is done by wrapping the event functions - event_add, event_delete and event_info. MultiCall recognizes only a subset of legal event sequences. Sequences which are not recognized are treated by the original Tk handling mechanism. A more-specific event will be called before a less-specific event. The recognized sequences are complete one-event sequences (no emacs-style Ctrl-X Ctrl-C, no shortcuts like <3>), for all types of events. Key/Button Press/Release events can have modifiers. The recognized modifiers are Shift, Control, Option and Command for Mac, and Control, Alt, Shift, Meta/M for other platforms. For all events which were handled by MultiCall, a new member is added to the event instance passed to the binded functions - mc_type. This is one of the event type constants defined in this module (such as MC_KEYPRESS). For Key/Button events (which are handled by MultiCall and may receive modifiers), another member is added - mc_state. This member gives the state of the recognized modifiers, as a combination of the modifier constants also defined in this module (for example, MC_SHIFT). Using these members is absolutely portable. The order by which events are called is defined by these rules: 1. A more-specific event will be called before a less-specific event. 2. A recently-binded event will be called before a previously-binded event, unless this conflicts with the first rule. Each function will be called at most once for each event. � N� � � � � � � � � � � � � � � � � � � � � � �darwin�Shift�Control�Option�Command�Alt�Meta�Mc C s" g | ]}t | D ] }||f�qqS � )� _modifiers)�.0�number�namer r �6/opt/alt/python36/lib64/python3.6/idlelib/multicall.py� <listcomp>7 s r& z application has been destroyedc @ s, e Zd Zdd� Zdd� Zdd� Zdd� Zd S ) � _SimpleBinderc C s8 || _ dt| d d | _|| _|| _g | _d | _d S )N�<r �>)�type�_types�sequence�widget� widgetinst� bindedfuncs� handlerid)�selfr* r- r. r r r% �__init__J s z_SimpleBinder.__init__c C s> | j s.| j| jfdd�}| jj| j| j|�| _ | jj|� d S )Nc S sT || _ i }xDtt|�d dd�D ],}|| }||kr d||< || �}|r |S q W d S )Nr T���r3 )�mc_type�range�len)�event�lr4 � wascalled�i�func�rr r r% �handlerT s z#_SimpleBinder.bind.<locals>.handler)r0 r/ r* r- �bindr. r, �append)r1 �tripletr; r= r r r% r> R s z_SimpleBinder.bindc C s2 | j j|� | j s.| jj| j| j| j� d | _d S )N)r/ �remover- �unbindr. r, r0 )r1 r@ r; r r r% rB b s z_SimpleBinder.unbindc C sZ | j rVy| jj| j| j| j � W n4 tjk rT } zt|jd krD� W Y d d }~X nX d S )Nr ) r0 r- rB r. r, �tkinter�TclError�APPLICATION_GONE�args)r1 �er r r% �__del__h s z_SimpleBinder.__del__N)�__name__� __module__� __qualname__r2 r> rB rH r r r r% r' I s r' c s( g | ] � d j � fdd�tt�D ���qS )� c 3 s* | ]"\}}d |> � @ r|d d V qdS )r r �-Nr )r" r: �m)�sr r% � <genexpr>w s z<listcomp>.<genexpr>)�join� enumerater! )r" r )rO r% r& w s c sP dd� }g }x>| D ]6� t t� fdd�| D ���}|j|dd� |j|� qW |S )z�For each item of states return a list containing all combinations of that item with individual bits reset, sorted by the number of set bits. c S s( d}x | r"t | d�\} }||7 }qW |S )z number of bits set in n base 2r r )�divmod)�nZnbZremr r r% �nbits� s z expand_substates.<locals>.nbitsc 3 s | ]}� |@ V qd S )Nr )r" �x)�stater r% rP � s z#expand_substates.<locals>.<genexpr>T)�key�reverse)�list�set�sortr? )ZstatesrU Z statelistZ substatesr )rW r% �expand_substates| s r] c @ s4 e Zd Zdd� Zdd� Zdd� Zdd� Zd d � Zd S ) �_ComplexBinderc C s |||| j | jfdd�}|S )Nc S s� dg|d d �< || _ || _i }d }xZ|D ]R}xFtt|�d dd�D ].} || } | |krBd|| < || | �}|rBP qBW |r(P q(W g |d d �< x|D ] } | � q�W g |d d �< |r�|S d S )NTr r3 r3 )r4 �mc_stater5 r6 ) r7 �listsr4 r_ �ishandlerrunning�doafterhandlerr9 r< r8 r: r; �fr r r% r= � s* z0_ComplexBinder.__create_handler.<locals>.handler)ra rb )r1 r` r4 r_ r= r r r% Z__create_handler� s z _ComplexBinder.__create_handlerc s� |� _ t| d � _|� _|� _d dd� tD �i� _g � _g � _g � _ xhtD ]`}� fdd�t | D �}� j ||t | �}dt | � j d }� jj|� jj� j||�f� qLW d S )Nr c S s g | ]}g �qS r r )r" rO r r r% r& � s z+_ComplexBinder.__init__.<locals>.<listcomp>c s g | ]}� j d | �qS )N)r/ )r" r: )r1 r r% r& � s r( r) )r* r+ �typenamer- r. �_statesr/ � handleridsra rb �_state_subsets� _ComplexBinder__create_handler� _state_codes� _state_namesr? r> )r1 r* r- r. rO r` r= �seqr )r1 r% r2 � s z_ComplexBinder.__init__c s� �d �j kr�dd� tD ��j �d < xrtD ]j���fdd��d d fD �}�j|�jt� �}dt� �j�d f }�jj|�j j �j ||�f� q,W � ��fdd�}�j s�|� n �j j|� d S )Nr c S s g | ]}g �qS r r )r" rO r r r% r& � s z'_ComplexBinder.bind.<locals>.<listcomp>c s( g | ] }t � D ]}�j| | �qqS r )rg r/ )r" �detailr: )rO r1 r r% r& � s z <%s%s-%s>c s �j �d �d j� �S )Nr r )r/ r? r )r; r1 r@ r r% �<lambda>� s z%_ComplexBinder.bind.<locals>.<lambda>)r/ re rh r* ri rj rd rf r? r- r> r. ra rb )r1 r@ r; r` r= rk �doitr )r; rO r1 r@ r% r> � s z_ComplexBinder.bindc s. � ��fdd�}�j s |� n �jj|� d S )Nc s �j �d �d j� �S )Nr r )r/ rA r )r; r1 r@ r r% rm � s z'_ComplexBinder.unbind.<locals>.<lambda>)ra rb r? )r1 r@ r; rn r )r; r1 r@ r% rB � s z_ComplexBinder.unbindc C sd x^| j D ]T\}}y| jj| j||� W q tjk rZ } zt|jd krJ� W Y d d }~X qX qW d S )Nr )rf r- rB r. rC rD rE rF )r1 rk �idrG r r r% rH � s z_ComplexBinder.__del__N)rI rJ rK rh r2 r> rB rH r r r r% r^ � s r^ �KeyPress�Key� KeyRelease� ButtonPress�Button� ButtonRelease�Activate� Circulate�Colormap� Configure� Deactivate�Destroy�Enter�Expose�FocusIn�FocusOut�Gravity�Leave�Map�Motion� MouseWheel�Property�Reparent�Unmap� Visibilityc C s" g | ]}t | D ] }||f�qqS r )r+ )r" r# r$ r r r% r& s z^\w+$z^[1-5]$c C s | s | d dks | d dkr"dS | dd � j d�}d}x.|rf|d tkrf|dt|d > O }|d= q:W |r�|d tkr�t|d }|d= ndS t| tkr�|s�|r�dS d}nP|dd� d D �kr�t}nt}|s�d}n*t|�dko�|j|d �� r�|d }ndS |||fS )a- Get a string which should describe an event sequence.
