2. Today GUI Construction With tkinter, Cont.:
Radiobutton and Canvas Widgets.
Bears Demo.
More Python tools and modules.
Winter 2018
CISC101 - Prof. McLeod

3. Radiobutton Widget See Window14.py
Each Radiobutton is bound to the same variable as well as triggering the same function.
You can only choose one Radiobutton at a time.

4. The Canvas Widget
You can use this widget to display any drawn shapes, or images, or even a turtle drawing.
The canvas can be interactive, allowing the cursor to draw or edit an image.
See:
Window15.py (drawn shapes)
Window15A.py (an image)
Window16.py (cursor drawing)
Window17.py (turtle drawing!)

5. An Advanced Demo: BearsDBV2.py
Allows viewing and editing of the bears database, one record at a time. (Based on Exercise 9.)
Entry Widgets, Buttons, Labels, a Frame, and a LabelFrame.
Control Variables.
Binding of control variables and handlers (functions).
No more globals! Handler functions have been declared inside main!
Button navigation.
Store and display images in a Canvas widget.
Use of a filedialog to obtain an image file.
Use of an errordialog to provide a file not found message.

6. Building a Game? Pygame is not a bad place to start.
You can build decent looking arcade-style games fairly easily.
(Python might not be the best choice of a platform for more complex or demanding games…)
See
Pygame was lagging behind Python versions, but developers have recently caught up.

7. Other GUI Tools Lots! IDE and different Widget sets.
See WxWidgets, for example.
Start by looking at:
WxPython:
Or see gui2py:

8. Other IDEs
IDLE is pretty simple and a good place to start learning Python.
But, it can be frustrating after a while if you are used to more sophisticated IDEs:
Poor intellisense and code completion.
No debugger.
No line numbering!
No code wizards, project browsers, etc.
“Multi-Lingual” IDEs like Visual Studio (uses “PTVS”), Eclipse (uses PyDev) and Qt can be configured to help write Python programs.

9. Other IDEs, Cont. PyCharm: http://www.jetbrains.com/pycharm/
Works on Windows, Mac and Linux.

11. For Example: Enthought Canopy
A collection of many packages from many sources – targeted towards data analysis, modeling and visualization.
Like Matlab, but based on Python and all code is open, not proprietary.
Now available for Python version 3.5.
Free for academic use!
Winter 2018
CISC101 - Prof. McLeod

12. Anaconda https://www.anaconda.com/download/
Comes with scientific packages included.
Free for academic use.
Available for Python 3.6.
Both Canopy and Anaconda will work with Windows, Mac and Linux.

13. Scientific Python IDE Pyzo. See: http://www.pyzo.org/
Noted for its web-based, simple interface.
Uses the Qt IDE for GUI development.
