Android Question When creating a new b4xPage Class

[PdeG]

in the Class_Globals this is created by default,

Sub Class_Globals
    Private Root As B4XView 'ignore
    Private xui As XUI 'ignore
End Sub

what is the meaning of 'ignore and what does it do?

Regards,
Peter

Try remove the 'ignore

Private Root As B4XView

You will get:

Unused variable 'Root'. (warning #9)

Now, try to add 'ignore after the line:

Private Root As B4XView 'ignore

The warning is gone.

The 'ignore keyword is use to suppress the warning. In most cases, you don't use it. It means the variable has not yet been used.

if you add a new variable or view to the Class_Globals but it is not used anywhere the IDE will throw a warning. Adding ignore will ignore the warning for the specific variable view

Wow Aeric, after several years of ignoring some of those warnings (which Erel told me once to ignore in general) I have a way now to eliminate those pesky warnings in my logs window. Yippee! Thanks Aeric, you library of code knowledge you. Now I hope Ivica loves me; maybe, maybe not.

But isn't easier to use

#IgnoreWarnings: 9

?

#IgnoreWarnings: 9

Thanks, does that mean it covers all those warnings with one line? (I had three warnings which I eliminated individually.)

?

if you DON´T want the warning at all, yes.

But usually the warning is a good thing. You can not find the problem if you don´t get it.

Getting the warning you now are able to decide whether this is OK for the mentioned variable or not.

You may want to ignore warnings (even of other types) only for some "objects" (unused variables, in this specific case), perhaps temporarily, and not for others and therefore use 'ignore instead of #IgnoreWarnings: 9.

Thanks Don, Luca and Aeric; and Peter for the thread.

If you change the scope of the variable to Public then the warning will not be shown.
But be aware that this can cause some unwanted side effects.
