When you first start up Xojo you will typically see a project window. This window represents the Xojo Integrated Development Environment. You use the IDE to create programs.
The Editing Area: This area is where you can drag and drop controls onto a window. It is also where code can be added to controls.
The Library/Inspector Panel: At the right of the project window is the Library/Inspector pane. You can toggle between the Library and Inspector by clicking the corresponding toolbar buttons.
The Library: This view shows the controls (objects) that you can add to a window.
The Inspector: This view shows the properties of a selected object (control).
You use the IDE to build your program. There are 3 main things that you do using the IDE.
1. Build your program’s interface
2. Add code to objects
3. Modify object properties
