From Apple to Raspberry Pi: Using Object Oriented Programming with Tkinter
We’ve been learning parts of Python together. So far we’ve learned the basics of Python and setting up classes and instances in it. We have a good start on using UI elements and styling them with the basics of tk and ttk. I’d like to make something more real than a demo program with the…

From Apple to Raspberry Pi: A Gentle Introduction to Themed Widgets With ttk
Up to this point we have used tkinter widgets. For every widget, we had to set all the attributes. We could have this on off panel of three buttons and a label: Type it in, save and run. Each button uses the same .configure() for every widget: While we have only three buttons, this can…

From Apple to Raspberry Pi: More Widgets! More Power!!!
We covered some of the major simple widgets in Tkinter. There are a few more used less regularly: radio buttons, checkboxes, sliders, and spinners. This lesson, we’ll look at those widgetsand make a better power panel. Control Variables We used control variables in the Button, Entry and Label widgets. The control variable in a button…

From Apple to Raspberry Pi: Making Round Rectangle Buttons — The Movie
When I posted yesterday about GIMP and making Buttons for Python projects on the Raspberry Pi, I had thought someone would have a tutorial for the classic pre-iOS7 rounded rectangle button. I didn’t find any. Here is a video I put together of making those buttons in GIMP on the Raspberry Pi. At the end…

From Apple to Raspberry Pi: Making Icons and Cool Buttons
If there is one thing that Apple developers believe, user interfaces needs to look cool. Looking cool often requires not text, but images on your on your controls. While not as robust as UIView and its subclasses, Tkinter does display graphics. We can add buttons that look a lot better than the standard buttons. Make…

From Apple to Raspberry Pi: Living without Storyboards and Interface Builder
In iOS, avoiding Interface Builder is nearly impossible. IB is old – as old as the Xcode SDK itself. Interface builder was one of the components of NextStep, and thus one of the reasons Steve Jobs got his old job back, who then developed NextStep into the platform for all Apple products. In more recent…

From Apple to Raspberry Pi: Configuring Buttons for GUI.
In our last installment, we learned how to add buttons and labels to a Python program. Now we are going to make them look a little nicer than the generic buttons we haven now using the configure method of Tkinter. Make a beginning framework To start, lets enter this code into a new window. Build…

From Apple to Raspberry Pi: Windows Buttons and Widgets — on Pi!
I’ve explored much of the basic coding in Python, but I’ll need a good user interface for the projects I’m doing. When it comes to the graphical user interface (GUI), Xcode and Python are on two different planets. With storyboards and interface builder, Xcode arguably spoils developers. There are times one does need to add…

From Apple to Raspberry Pi: Importing Classes and Disturbing Attributes.
I didn’t do as much As I thought I would today, as I was installing tightvnc on the Raspberry Pi. I then tried out acessing my RasPi on my Mac, Pc, and even my iPad mini. I wasn’t nuts enough t try it on my iPhone — yet. I did download the app though. …

from Apple to Raspberry Pi: Making Classes in Python
Objective-C and Python are similar when it comes to defining new classes, but be careful with their differences. In Objective-C we would define a class with two files: a header and an implementation file. In the header we would declare properties like this And possibly public methods In the implementation file we would have the…
