Select a demoscript from the example menu. The (syntax colored) source code appears in the left source code window. IT CANNOT BE EDITED, but ONLY VIEWED! The demo viewer windows can be resized. The divider between text and canvas can be moved by grabbing it with the mouse. The text font size can be changed from the menu and with Control/Command '-'/'+'. It can also be changed on most systems with Control-mousewheel when the mouse is over the text. Press START button to start the demo. Stop execution by pressing the STOP button. Clear screen by pressing the CLEAR button. Restart by pressing the START button again. SPECIAL demos, such as clock.py are those which run EVENTDRIVEN. Press START button to start the demo. - Until the EVENTLOOP is entered everything works as in an ordinary demo script. - When the EVENTLOOP is entered, you control the application by using the mouse and/or keys (or it's controlled by some timer events) To stop it you can and must press the STOP button. While the EVENTLOOP is running, the examples menu is disabled. - Only after having pressed the STOP button, you may restart it or choose another example script. * * * * * * * * In some rare situations there may occur interferences/conflicts between events concerning the demo script and those concerning the demo-viewer. (They run in the same process.) Strange behaviour may be the consequence and in the worst case you must close and restart the viewer. * * * * * * * * (2) How to add your own demos to the demo repository - Place the file in the same directory as turtledemo/__main__.py IMPORTANT! When imported, the demo should not modify the system by calling functions in other modules, such as sys, tkinter, or turtle. Global variables should be initialized in main(). - The code must contain a main() function which will be executed by the viewer (see provided example scripts). It may return a string which will be displayed in the Label below the source code window (when execution has finished.) - In order to run mydemo.py by itself, such as during development, add the following at the end of the file: if __name__ == '__main__': main() mainloop() # keep window open python -m turtledemo.mydemo # will then run it - If the demo is EVENT DRIVEN, main must return the string "EVENTLOOP". This informs the demo viewer that the script is still running and must be stopped by the user! If an "EVENTLOOP" demo runs by itself, as with clock, which uses ontimer, or minimal_hanoi, which loops by recursion, then the code should catch the turtle.Terminator exception that will be raised when the user presses the STOP button. (Paint is not such a demo; it only acts in response to mouse clicks and movements.)

Select a demoscript from the example menu. The (syntax colored) source code appears in the left source code window. IT CANNOT BE EDITED, but ONLY VIEWED! The demo viewer windows can be resized. The divider between text and canvas can be moved by grabbing it with the mouse. The text font size can be changed from the menu and with Control/Command '-'/'+'. It can also be changed on most systems with Control-mousewheel when the mouse is over the text. Press START button to start the demo. Stop execution by pressing the STOP button. Clear screen by pressing the CLEAR button. Restart by pressing the START button again. SPECIAL demos, such as clock.py are those which run EVENTDRIVEN. Press START button to start the demo. - Until the EVENTLOOP is entered everything works as in an ordinary demo script. - When the EVENTLOOP is entered, you control the application by using the mouse and/or keys (or it's controlled by some timer events) To stop it you can and must press the STOP button. While the EVENTLOOP is running, the examples menu is disabled. - Only after having pressed the STOP button, you may restart it or choose another example script. * * * * * * * * In some rare situations there may occur interferences/conflicts between events concerning the demo script and those concerning the demo-viewer. (They run in the same process.) Strange behaviour may be the consequence and in the worst case you must close and restart the viewer. * * * * * * * * (2) How to add your own demos to the demo repository - Place the file in the same directory as turtledemo/__main__.py IMPORTANT! When imported, the demo should not modify the system by calling functions in other modules, such as sys, tkinter, or turtle. Global variables should be initialized in main(). - The code must contain a main() function which will be executed by the viewer (see provided example scripts). It may return a string which will be displayed in the Label below the source code window (when execution has finished.) - In order to run mydemo.py by itself, such as during development, add the following at the end of the file: if __name__ == '__main__': main() mainloop() # keep window open python -m turtledemo.mydemo # will then run it - If the demo is EVENT DRIVEN, main must return the string "EVENTLOOP". This informs the demo viewer that the script is still running and must be stopped by the user! If an "EVENTLOOP" demo runs by itself, as with clock, which uses ontimer, or minimal_hanoi, which loops by recursion, then the code should catch the turtle.Terminator exception that will be raised when the user presses the STOP button. (Paint is not such a demo; it only acts in response to mouse clicks and movements.) � N)�*)�ColorDelegator� color_config)� Percolator)� view_text)�__doc__�darwin� � � � � �Arial� )r r ZboldzLucida Console� �normal� �d � � � � � � � � � c C s dd� t �t�D �S )Nc S s. g | ]&}|� d �r|d dkr|dd� �qS )z.pyr �_N���)�endswith)�.0�entry� r" �+/usr/lib64/python3.8/turtledemo/__main__.py� <listcomp>t s �z%getExampleEntries.<locals>.<listcomp>)�os�listdir�demo_dirr" r" r" r# �getExampleEntriess s r( zTurtledemo helpzAbout turtledemozAbout turtle modulec @ s� e Zd Zd(dd�Zdd� Zdd� Zdd � Zd d � Zd)d d �Zd*dd�Z dd� Z d+dd�Z dd� Z dd� Z dd� Zd d � Zd d � Zd d!� Zd"d#� Zd$d%� Zd&d'� ZdS ),� DemoWindowNc C sJ t � | _ }t_|�d� |�d| j� trbdd l}|j ddddd� t � � �ddg|j |j d � |jdd d � |jdd d � |jd d d d � |jdd d d � |jdd d d � t|tdd�| _| jj| �| j�ddd� | jj| �| j�ddd� | jj| �| j�ddd� | j|d< ttdtdd�}|�| �|�� |�| � |�� |j dddd� t |d d d d dt d �| _ t!|d t"d!d"| j#d#�| _$t!|d$t"d!d"| j%d#�| _&t!|d%t"d!d"| j'd#�| _(| j j d ddd&d'� | j$j d d d(d)� | j&j d dd(d)� | j(j d dd(d)� t)| j*��+t,� � d*| _-d*| _.|�r.| �/|� | �0t1t1t1d+d,� t2| _3d S )-Nz Python turtle-graphics examplesZWM_DELETE_WINDOWr Z osascriptz-ez tell application "System Events"z>set frontmost of the first process whose unix id is {} to truezend tell)�stderr�stdoutr )�weight�Z )Zminsizer, r r )�relief� borderwidthZExamples)�menu�label� underlineZFontsizeZHelpr0 r z#ddd)�orientZ sashwidthZ sashrelief�bgr Znews)�rowZ columnspan�stickyz --- z#ddf)r � r )Zheight�textr4 �fontr/ r. z START Zwhitez#fed)r8 r9 �fgZdisabledforeground�commandz STOP z CLEAR )r r )r5 �columnr6 �padxZew)r5 r< r6 FzChoose example from menu�black)4ZTk�root�turtle�_root�titleZ wm_protocol�_destroyr � subprocess�run�formatr% �getpidZDEVNULLZgrid_rowconfigureZgrid_columnconfigure�MenuZRAISEDZmBarZ add_cascade�makeLoadDemoMenu� makeFontMenu� makeHelpMenuZ PanedWindow� HORIZONTALZSOLID�add� makeTextFrame�makeGraphFrameZgridZLabelZRIDGE� output_lblZButton�btnfont� startDemo� start_btn�stopIt�stop_btn� clearCanvas� clear_btnr r8 Z insertfilterr �dirty�exitflag�loadfile� configGUI�DISABLED�STARTUP�state)�self�filenamer? rD Zpaner" r" r# �__init__� s� � �� � � � � � � � � �zDemoWindow.__init__c C sP | j �� }| j �� }| j �d| j| | j � | j �d| j| | j � d S )Ng �?)�_canvasZ winfo_widthZ winfo_heightZ xview_moveto� canvwidthZ yview_moveto� canvheight)r_ �eventZcwidthZcheightr" r" r# �onResize� s zDemoWindow.onResizec C s6 t |� | _}t|ddddd� | _}t|� t|dd� | _}|j|d< |jt t d � t|d t d � | _ }|j |d< |jttd � |j|d < |j|d < tt�|d< tr�dnd}|�d| | j� |�d| | j� |�d| | j� |�d| | j� |�d| j� |�d| j� |�d| j� |jt tdd� |S )Nr8 r Znone�- )�namer= Zwrap�width�vbar)rh r; )�side�fill�hbar)rh r3 ZyscrollcommandZxscrollcommandr9 ZCommandZControlz <%s-minus>z<%s-underscore>z <%s-equal>z <%s-plus>z<Control-MouseWheel>z<Control-Button-4>z<Control-Button-5>r )rk rl �expand)ZFrame� text_frameZTextr8 r Z Scrollbarrj ZyviewZpackZLEFT�YrL rm ZxviewZBOTTOM�X�set�tuple�txtfontr Zbind_all� decrease_size� increase_size�bind�update_mousewheelZBOTH)r_ r? ro r8 rj rm Zshortcutr" r" r# rN � s2 � zDemoWindow.makeTextFramec C s� |t j_d| _d| _t �|dd| j| j� t j_ | _}|�� |j� d| j � d|jd< t � � | _ }t j �||j� |j| _|gt j_|S )Ni� i iX z <Configure>r r/ )r@ Z_ScreenrA rc rd ZScrolledCanvasrb Z adjustScrollsZ _rootwindowrw rf ZScreen�screen� TurtleScreenra �scanvasZ RawTurtleZscreens)r_ r?

Select a demoscript from the example menu. The (syntax colored) source code appears in the left source code window. IT CANNOT BE EDITED, but ONLY VIEWED! The demo viewer windows can be resized. The divider between text and canvas can be moved by grabbing it with the mouse. The text font size can be changed from the menu and with Control/Command '-'/'+'. It can also be changed on most systems with Control-mousewheel when the mouse is over the text. Press START button to start the demo. Stop execution by pressing the STOP button. Clear screen by pressing the CLEAR button. Restart by pressing the START button again. SPECIAL demos, such as clock.py are those which run EVENTDRIVEN. Press START button to start the demo. - Until the EVENTLOOP is entered everything works as in an ordinary demo script. - When the EVENTLOOP is entered, you control the application by using the mouse and/or keys (or it's controlled by some timer events) To stop it you can and must press the STOP button. While the EVENTLOOP is running, the examples menu is disabled. - Only after having pressed the STOP button, you may restart it or choose another example script. * * * * * * * * In some rare situations there may occur interferences/conflicts between events concerning the demo script and those concerning the demo-viewer. (They run in the same process.) Strange behaviour may be the consequence and in the worst case you must close and restart the viewer. * * * * * * * * (2) How to add your own demos to the demo repository - Place the file in the same directory as turtledemo/__main__.py IMPORTANT! When imported, the demo should not modify the system by calling functions in other modules, such as sys, tkinter, or turtle. Global variables should be initialized in main(). - The code must contain a main() function which will be executed by the viewer (see provided example scripts). It may return a string which will be displayed in the Label below the source code window (when execution has finished.) - In order to run mydemo.py by itself, such as during development, add the following at the end of the file: if __name__ == '__main__': main() mainloop() # keep window open python -m turtledemo.mydemo # will then run it - If the demo is EVENT DRIVEN, main must return the string "EVENTLOOP". This informs the demo viewer that the script is still running and must be stopped by the user! If an "EVENTLOOP" demo runs by itself, as with clock, which uses ontimer, or minimal_hanoi, which loops by recursion, then the code should catch the turtle.Terminator exception that will be raised when the user presses the STOP button.
