Debugging Functions
DV(view)
DV
function takes a view as a parameter and prints information about that view, along with all its children, in a compact one-line-per-view format. You also get a quick flash of the view on the Newton--making it more easily identifiable.
Consider as an example a protoFloatNGo
named "myFloatNGo" containing a protoStaticText
named "myStaticText". Executing:
floater:= Debug("myFloatNGo"); DV(floater);produces the following output:
The wholemyFloatNGo #440D31D [ 38, 54,202,146] 241 vVisible vFloating vClickable
|1451352 #4417E05 [188,132,201,145] 203 vVisible vReadOnly vClickable
|myStaticText #4417E1D [ 78, 86,174,110] 3 vVisible vReadOnly
protoFloatNGo
flashes momentarily (see FIGURE 8.9) and then the output appears in the Inspector. The vertical bar (|
) at the left of each line shows you the nesting level. Notice that you also see the viewBounds
(in screen coordinates), along with a viewFlags
summary.

causes the protoFloatNGo view to flash.
Using the same example, executing:
DV(Debug("myStaticText"));produces the following output:
myStaticText #4417EF5 [78, 86,174,110] 3 vVisible vReadOnly
In addition to the output, the static text also gives the comforting flash (see FIGURE 8.10).
