3: Propeller Programming Tutorial
The Object View updates itself each time an application is successfully compiled to show you
the logical structure of that application. The view shown in Figure 3-12 is the Object View’s
way of illustrating the logical structure in Figure 3-11. It is necessary to check the Object
View once in a while to troubleshoot or to verify proper compilation.
Your entire application is displayed in the Object View, or at least what it looked like after
the last successful compile. You can also use it to explore the application. For example,
pointing the mouse at each object in the Object View gives you hint information about that
object. Left-clicking each of those objects either opens them up or switches the active edit
tab to that object. Right-clicking each of those objects does the same as left-clicking but it
makes the object switch to Documentation view instead of Full Source view.
Top Object File
The object at the top of the Object View is always the “Top Object File” for that particular
compilation. That means the compilation started from Blinker1, in this case. When we
compile by using the F10 or F11 shortcut keys, or their corresponding menus, the Propeller
Tool starts the compile operation using whatever edit tab is active at that moment. The active
edit tab is the one that is highlighted differently than the rest; see Pane 4: Editor Pane on page
40 and Figure 2-4 on page 40 for an example.
If we had accidentally clicked on the Output object’s tab first and then compiled with F10 or
F11 the compile would have started from that object instead. This would not have resulted in
the application we desired and the Object View would have shown only one object, Output,
in its structure. This is all because the compile functions we’ve been using are the “Compile
Current” options; meaning they compile from the currently active object, or edit tab.
There are other compile functions that can help us. Select the Run menu and look at the
options. You should see a “Compile Current” and “Compile Top” flyout menu (Figure 3-13).
