For wheel up, event.delta = 120*n on Windows, -1*n on darwin, where n can be > 1 if one scrolls fast. Flicking the wheel generates up to maybe 20 events with n up to 10 or more 1. Macs use wheel down (delta = 1*n) to scroll up, so positive delta means to scroll up on both systems. X-11 sends Control-Button-4,5 events instead. The widget parameter is needed so browser label bindings can pass the underlying canvas. This function depends on widget.yview to not be overridden by a subclass. r � ���� NZunits�break) Z EventTypeZ MouseWheelZdeltaZ ButtonPressZnum�type�widget�yviewZSCROLL)�eventr) Zup�linesr! r! r" � wheel_event; s r- c @ s� e Zd Zdd� Zdd� Zdd� Zd*dd �Zd+d d �Zd d � Zdd� Z d,dd�Z d-dd�Z d.dd�Z dd� Z dd� Zdd� Zd d � Zd d � Zd d!� Zd/d"d#�Zd0d$d%�Zd1d&d'�Zd2d(d)�ZdS )3�TreeNodec C s: || _ || _|| _d| _d| _g | _d | _| _i | _d S )N� collapsedF) �canvas�parent�item�state�selected�children�x�y� iconimages)�selfr0 r1 r2 r! r! r" �__init__V s zTreeNode.__init__c C s6 x*| j d d � D ]}| j �|� |�� qW d | _d S )N)r5 �remove�destroyr1 )r9 �cr! r! r" r< ` s zTreeNode.destroyc C sf y | j | S tk r Y nX tj�|�\}}|p6d}tj�t|| �}t| j|d�}|| j |< |S )Nz.gif)r r ) r8 �KeyErrorr r r r �ICONDIRr r0 )r9 r r Zext�fullnamer r! r! r" � geticonimagef s zTreeNode.geticonimageNc C s: | j r d S | �� d| _ | j�| j� | �� | �� d S )NT)r4 � deselectallr0 �delete�image_id�drawicon�drawtext)r9 r+ r! r! r" �selectr s zTreeNode.selectc C s2 | j s d S d| _ | j�| j� | �� | �� d S )NF)r4 r0 rC rD rE rF )r9 r+ r! r! r" �deselect{ s zTreeNode.deselectc C s | j r| j �� n| �� d S )N)r1 rB � deselecttree)r9 r! r! r" rB � s zTreeNode.deselectallc C s* | j r| �� x| jD ] }|�� qW d S )N)r4 rH r5 rI )r9 �childr! r! r" rI � s zTreeNode.deselecttreec C s* | j dkr| �� n| �� | j�� dS )N�expandedr' )r3 �collapse�expandr2 � OnDoubleClick)r9 r+ r! r! r" �flip� s z TreeNode.flipc C s2 | j �� sd S | jdkr.d| _| �� | �� d S )NrK )r2 � _IsExpandabler3 �update�view)r9 r+ r! r! r" rM � s zTreeNode.expandc C s | j dkrd| _ | �� d S )Nr/ )r3 rQ )r9 r+ r! r! r" rL � s zTreeNode.collapsec C s� | j d }| �� j d }|| }| j�d�}| j�� }| j�|�}||krV||krVd S | j�| jd �\}}} } ||kr�||kr�|| | } n|} t| �| } | j�| � d S )Nr � r � scrollregion)r7 �lastvisiblechildr0 ZcanvasyZ winfo_heightZ_getints�floatZ yview_moveto) r9 �topZbottomZheightZ visible_topZvisible_heightZvisible_bottom�x0�y0�x1�y1Zfractionr! r! r" rR � s z TreeNode.viewc C s& | j r | jdkr | j d �� S | S d S )NrK ���)r5 r3 rU )r9 r! r! r" rU � s zTreeNode.lastvisiblechildc C s� | j r| j �� nj| jd }d| jd< | j�� | j�t� | �dd� | j�t�\}}}}| jjdd||fd� || jd< d S )NZcursorZwatch� r r )rT )r1 rQ r0 rC ZALL�draw�bbox� configure)r9 Z oldcursorrX rY rZ r[ r! r! r" rQ � s zTreeNode.updatec C sx d}|| | _ | _| �� | �� | jdkr4|| S | jsz| j�� }|sP|d S x(|D ] }| �| j | |�}| j� |� qVW |d }|| }d} x�| jD ]�}|} | j j |d |d ||d dd� |� ||�}|j� � r�|jdkr�d } |j} n d } |j} | �| �} | j j|d | d | d �} | j �| d | � | j �| d dd� � q�W | j j |d |d |d | d dd�} | j �| � |S )N� rK rS r � r] Zgray50)�fillZ minusnodeZplusnode)r z<1>z <Double-1>c S s d S )Nr! )r6 r! r! r" �<lambda>� � z TreeNode.draw.<locals>.<lambda>r )r6 r7 rE rF r3 r5 r2 � _GetSubList� __class__r0 r Z create_liner^ rP rL rM rA � create_image�tag_bindZ tag_lower)r9 r6 r7 Zdy�sublistr2 rJ ZcxZcyZcylastZiconname�callbackr �idr! r! r" r^ � sD " z TreeNode.drawc C s~ | j r | j�� p | j�� p d}n| j�� p,d}| �|�}| jj| j| jd|d�}|| _ | j� |d| j � | j� |d| j � d S )NZ openfolderZfolder�nw)�anchorr z<1>z <Double-1>) r4 r2 �GetSelectedIconName� GetIconNamerA r0 rh r6 r7 rD ri rG rO )r9 Z imagenamer rl r! r! r" rE � s zTreeNode.drawiconc s� � j d d }� jd }� j�� }|r�� jj||d|d�}� j�|d� j� � j�|d� j� � j� |�\}}}}t |d�d }� j� � p�d } y � j W n t k r� Y n X � �� y � j W n* t k r� t� j| d d d d �� _Y nX t�� } � j�r� j�t�| d�� n� j�t�| d�� � jj||d� jd�}� j�d� j� � j�d� j� � j�d� fdd�� � j�d� fdd�� � j�d� fdd�� |� _d S )Nra r r$ rm )rn r z<1>z <Double-1>�� r z <no text>r r )r r ZpadxZpadyZhiliteZnormal)rn Zwindowz <MouseWheel>c s t | � j�S )N)r- r0 )�e)r9 r! r" rd re z#TreeNode.drawtext.<locals>.<lambda>z <Button-4>c s t | � j�S )N)r- r0 )rr )r9 r! r" rd re z <Button-5>c s t | � j�S )N)r- r0 )rr )r9 r! r" rd ! re )r6 r7 r2 � GetLabelTextr0 Z create_textri rG rO r_ �max�GetText�entry�AttributeError� edit_finishr r r Z CurrentThemer4 r` Z GetHighlightZ create_window�bind�select_or_editZtext_id) r9 ZtextxZtextyZ labeltextrl rX rY rZ r[ r Zthemer! )r9 r" rF � s@ zTreeNode.drawtextc C s* | j r | j�� r | �|� n | �|� d S )N)r4 r2 � IsEditable�editrG )r9 r+ r! r! r" rz $ s zTreeNode.select_or_editc C sr t | jdddd�| _| j�d| jd � | j�dt� | jjdd� | j�� | j�d| j � | j�d| j � d S ) Nr r )r �highlightthickness�widthr r& )Zipadxz<Return>z<Escape>) ZEntryr rv �insertZselection_rangeZEND�pack� focus_setry rx � edit_cancel)r9 r+ r! r! r" r| * s z TreeNode.editc C s| y| j }| ` W n tk r" d S X |�� }|�� |rR|| j�� krR| j�|� | j�� }|| jd< | �� | j � � d S )Nr ) rv rw �getr< r2 ru �SetTextr rF r0 r� )r9 r+ rv r r! r! r" rx 3 s zTreeNode.edit_finishc C sB y| j }| ` W n tk r" d S X |�� | �� | j�� d S )N)rv rw r< rF r0 r� )r9 r+ rv r! r! r" r� B s zTreeNode.edit_cancel)N)N)N)N)N)N)N)N)N)�__name__� __module__� __qualname__r: r< rA rG rH rB rI rO rM rL rR rU rQ r^ rE rF rz r| rx r� r! r! r! r" r.
