Example Projects

I have found that, where REALbasic is concerned, I learn best by examining examples of working projects to see how they function. Here are descriptions of some example projects you can download. The code of each project is heavily commented to help you understand what is going on.

EG.
// open the image file then display it in Canvas1
thePic = f.OpenAsPicture
Canvas1.backdrop = thePic

To learn from these example projects I suggest the following stategy (but you may want to adopt your own approach):
1. Download the project
2. Double-click the project file to open it in REALbasic
3. Run the project to see what it does (choose Run from the Debug menu)
4. Quit the running project
5. Choose a particular feature of the project to examine (eg. clicking a button displays a picture)
6. Examine the code and comments in any objects that you think might be related to the feature (eg. a pushbutton, a canvas, a window, etc.) to figure out how the program feature works.
NOTE: Every window code editor has a "Notes" section in the list on the left of the code editor window. Be sure to check for any notes in window code editors when you open them.
