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�McCs"g|]}t|D]}||f�qqS�)� _modifiers)�.0�number�namer r �6/opt/alt/python36/lib64/python3.6/idlelib/multicall.py� 7sr&zapplication has been destroyedc@s,eZdZdd�Zdd�Zdd�Zdd�Zd S) � _SimpleBindercCs8||_dt|dd|_||_||_g|_d|_dS)N�)�type�_types�sequence�widget� widgetinst�bindedfuncs� handlerid)�selfr*r-r.r r r%�__init__Jsz_SimpleBinder.__init__cCs>|js.|j|jfdd�}|jj|j|j|�|_|jj|�dS)NcSsT||_i}xDtt|�ddd�D],}||}||kr d||<||�}|r |Sq WdS)NrT��r3)�mc_type�range�len)�event�lr4� wascalled�i�func�rr r r%�handlerTsz#_SimpleBinder.bind..handler)r0r/r*r-�bindr.r,�append)r1�tripletr;r=r r r%r>Rs z_SimpleBinder.bindcCs2|jj|�|js.|jj|j|j|j�d|_dS)N)r/�remover-�unbindr.r,r0)r1r@r;r r r%rBbsz_SimpleBinder.unbindcCsZ|jrVy|jj|j|j|j�Wn4tjk rT}zt|jdkrD�WYdd}~XnXdS)Nr) r0r-rBr.r,�tkinter�TclError�APPLICATION_GONE�args)r1�er r r%�__del__hsz_SimpleBinder.__del__N)�__name__� __module__�__qualname__r2r>rBrHr r r r%r'Isr'cs(g|] �dj�fdd�tt�D��qS)�c3s*|]"\}}d|>�@r|ddVqdS)rr�-Nr )r"r:�m)�sr r%� wsz.)�join� enumerater!)r"r )rOr%r&wscsPdd�}g}x>|D]6�tt�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. cSs(d}x|r"t|d�\}}||7}qW|S)znumber of bits set in n base 2rr)�divmod)�nZnbZremr r r%�nbits�s zexpand_substates..nbitsc3s|]}�|@VqdS)Nr )r"�x)�stater r%rP�sz#expand_substates..T)�key�reverse)�list�set�sortr?)ZstatesrUZ statelistZ substatesr )rWr%�expand_substates|s r]c@s4eZdZdd�Zdd�Zdd�Zdd�Zd d �ZdS)�_ComplexBindercCs||||j|jfdd�}|S)NcSs�dg|dd�<||_||_i}d}xZ|D]R}xFtt|�ddd�D].} || } | |krBd|| <|| |�}|rBPqBW|r(Pq(Wg|dd�<x|D] }|�q�Wg|dd�<|r�|SdS)NTrr3r3)r4�mc_stater5r6)r7�listsr4r_�ishandlerrunning�doafterhandlerr9r<r8r:r;�fr r r%r=�s* z0_ComplexBinder.__create_handler..handler)rarb)r1r`r4r_r=r r r%Z__create_handler�s z_ComplexBinder.__create_handlercs�|�_t|d�_|�_|�_ddd�tD�i�_g�_g�_g�_ xhtD]`}�fdd�t |D�}�j||t|�}dt |�jd}�jj|�jj�j||�f�qLWdS)NrcSsg|]}g�qSr r )r"rOr r r%r&�sz+_ComplexBinder.__init__..csg|]}�jd|�qS)N)r/)r"r:)r1r r%r&�sr(r))r*r+�typenamer-r.�_statesr/� handleridsrarb�_state_subsets�_ComplexBinder__create_handler�_state_codes�_state_namesr?r>)r1r*r-r.rOr`r=�seqr )r1r%r2�s z_ComplexBinder.__init__cs��d�jkr�dd�tD��j�d<xrtD]j��fdd��ddfD�}�j|�jt��}dt��j�df}�jj|�j j �j||�f�q,W��fdd�}�js�|�n�j j|�dS)NrcSsg|]}g�qSr r )r"rOr r r%r&�sz'_ComplexBinder.bind..cs(g|] }t�D]}�j||�qqSr )rgr/)r"�detailr:)rOr1r r%r&�sz <%s%s-%s>cs�j�d�dj��S)Nrr)r/r?r )r;r1r@r r%��sz%_ComplexBinder.bind..)r/rerhr*rirjrdrfr?r-r>r.rarb)r1r@r;r`r=rk�doitr )r;rOr1r@r%r>�s z_ComplexBinder.bindcs.��fdd�}�js|�n�jj|�dS)Ncs�j�d�dj��S)Nrr)r/rAr )r;r1r@r r%rm�sz'_ComplexBinder.unbind..)rarbr?)r1r@r;rnr )r;r1r@r%rB�sz_ComplexBinder.unbindcCsdx^|jD]T\}}y|jj|j||�Wqtjk rZ}zt|jdkrJ�WYdd}~XqXqWdS)Nr)rfr-rBr.rCrDrErF)r1rk�idrGr r r%rH�sz_ComplexBinder.__del__N)rIrJrKrhr2r>rBrHr 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� VisibilitycCs"g|]}t|D]}||f�qqSr )r+)r"r#r$r r r%r&sz^\w+$z^[1-5]$cCs|s|ddks|ddkr"dS|dd�jd�}d}x.|rf|dtkrf|dt|d>O}|d=q:W|r�|dtkr�t|d}|d=ndSt|tkr�|s�|r�dSd}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.
