Excerpt of article text...
In last issue's column, we learned about the basics of IPC sockets, and how we could implement a skeleton framework providing GUI services for Python applications. We will now push the idea beyond the proof of concept stage, and produce a less theoretical and much more usable framework.
Objectives
To make it more (re)usable, we will split the Python code: a Python module that implements GUI objects and IPC connectivity, and a sample test application that will make use of this Python framework. You will remember that in the last column, we had only one Python file that served as a test program and also implemented the communication process between the Python script and the RB framework. This was good enough for a test script demonstrating the functionalities of IPCSocket control. Now, if we want to get serious about this, we should provide the Python equivalent of RB's classes and modules -- same OOP logic, albeit in a less ordered, graphical, fashion.
For each GUI control we want to implement, we'll have to write a class that implements various behaviors. For the end-user, creating GUI controls should be as simple as w=RBWindow(...). All the IPC wizardry will be done behind the scenes, in the Python framework.
