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)ZOption)ZCommand))r )ZAlt)r )ZMeta�Mc C s" g | ]}t | D ] }||f�qqS � )� _modifiers)�.0�number�namer r �6/opt/alt/python37/lib64/python3.7/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�}| j�| j| j|�| _ | j�|� d S )Nc S sT || _ i }xDtt|�d dd�D ],}|| }||kr d||< || �}|r |S q W d S )Nr ���T)�mc_type�range�len)�event�lr3 � wascalled�i�func�rr r r$ �handlerT s z#_SimpleBinder.bind.<locals>.handler)r/ r. r) r, �bindr- r+ �append)r0 �tripletr: r< r r r$ r= R s z_SimpleBinder.bindc C s2 | j �|� | j s.| j�| j| j| j� d | _d S )N)r. �remover, �unbindr- r+ r/ )r0 r? r: r r r$ rA b s z_SimpleBinder.unbindc C sZ | j rVy| j�| j| j| j � W n4 tjk rT } zt|jd krD� W d d }~X Y nX d S )Nr ) r/ r, rA r- r+ �tkinter�TclError�APPLICATION_GONE�args)r0 �er r r$ �__del__h s z_SimpleBinder.__del__N)�__name__� __module__� __qualname__r1 r= rA rG r r r r$ r& I s r& c s( g | ] � d � � fdd�tt�D ���qS )� c 3 s* | ]"\}}d |> � @ r|d d V qdS )r r �-Nr )r! r9 �m)�sr r$ � <genexpr>w s z<listcomp>.<genexpr>)�join� enumerater )r! r )rN r$ r% w s c sP dd� }g }x>| D ]6� t t� fdd�| D ���}|j|dd� |�|� 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$ rO � s z#expand_substates.<locals>.<genexpr>T)�key�reverse)�list�set�sortr> )ZstatesrT Z statelistZ substatesr )rV 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 r2 )r3 �mc_stater4 r5 ) r6 �listsr3 r^ �ishandlerrunning�doafterhandlerr8 r; r7 r9 r: �fr r r$ r< � s* z0_ComplexBinder.__create_handler.<locals>.handler)r` ra )r0 r_ r3 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 �}� � ||t | �}dt | � j d }� j�|� j�� j||�f� qLW d S )Nr c S s g | ]}g �qS r r )r! rN r r r$ r% � s z+_ComplexBinder.__init__.<locals>.<listcomp>c s g | ]}� j d | �qS )N)r. )r! r9 )r0 r r$ r% � s r' r( )r) r* �typenamer, r- �_statesr. � handleridsr` ra �_state_subsets� _ComplexBinder__create_handler� _state_codes� _state_namesr> r= )r0 r) r, r- rN r_ r< �seqr )r0 r$ r1 � s z_ComplexBinder.__init__c s� �d �j kr�dd� tD ��j �d < xrtD ]j���fdd��d d fD �}��|�jt� �}dt� �j�d f }�j�|�j � �j ||�f� q,W � ��fdd�}�j s�|� n �j �|� d S )Nr c S s g | ]}g �qS r r )r! rN r r r$ r% � s z'_ComplexBinder.bind.<locals>.<listcomp>c s( g | ] }t � D ]}�j| | �qqS r )rf r. )r! �detailr9 )rN r0 r r$ r% � s z <%s%s-%s>c s �j �d �d �� �S )Nr r )r. r> r )r: r0 r? r r$ �<lambda>� � z%_ComplexBinder.bind.<locals>.<lambda>)r. rd rg r) rh ri rc re r> r, r= r- r` ra )r0 r? r: r_ r< rj �doitr )r: rN r0 r? r$ r= � s z_ComplexBinder.bindc s. � ��fdd�}�j s |� n �j�|� d S )Nc s �j �d �d �� �S )Nr r )r. r@ r )r: r0 r? r r$ rl � rm z'_ComplexBinder.unbind.<locals>.<lambda>)r` ra r> )r0 r? r: rn r )r: r0 r? r$ rA � s z_ComplexBinder.unbindc C sd x^| j D ]T\}}y| j�| j||� W q tjk rZ } zt|jd krJ� W d d }~X Y qX qW d S )Nr )re r, rA r- rB rC rD rE )r0 rj �idrF r r r$ rG � s z_ComplexBinder.__del__N)rH rI rJ rg r1 r= rA rG r r r r$ r] � s r] ))�KeyPressZKey)� KeyRelease)Z ButtonPressZButton)Z ButtonRelease)ZActivate)Z Circulate)ZColormap)Z Configure)Z Deactivate)ZDestroy)ZEnter)ZExpose)ZFocusIn)ZFocusOut)ZGravity)ZLeave)ZMap)ZMotion)Z MouseWheel)ZProperty)ZReparent)ZUnmap)Z 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 | r | d dks | d dkr dS | dd� � d�}d}x.|rd|d tkrd|dt|d > O }|d= q8W |r�|d tkr�t|d }|d= ndS t| tkr�|s�|r�dS d}nN|dd � d D �kr�t}nt}|s�d}n(t|�dkr�|�|d �r�|d }ndS |||fS ) a- Get a string which should describe an event sequence.
