Too fast? Pause the video. Download C and Python source code from thenerdshow.com For Python, refer to Part 5 of this series. It should be up now. There were some technical difficulties. Free cross-platform rapid application development was never so rapid or easy as it is using Glade 3.0′s interface designer. The new version will save in either GtkBuilder or Libglade format xml for easy integration into the programming environment. Using the robust and lightening-fast C language or the versatile and easy to grasp python language back end gives programmers the best of both worlds. As everyone knows, C code generation has been removed from Glade 3.0. This is a good thing because the code it generated was rather bloated and prolonged the usage of outdated conventions (difficult to maintain). By putting the interface into a separate xml file, Glade allows programmers or even end users to tweak the interface without re-compiling. As we shall see in a future video, the program logic to make this application work will be one page of easily readable C code. Stay tuned!
