Android Question get B4XPage from a XUI CustomView

[Alessandro71]

How can I can get the B4XPage object which a CustomView belongs to, from inside a CustomView sub.
Maybe from mBase itself?

Maybe from mBase itself?

I think you can get only the Root of the page, using
Dim ParentRoot As B4xView = mBase.Parent

You can use this code to get B4XPageInfo from a view. You do need to pass mBase for custom views, as this is the real view.

Public Sub GetPageInfoFromView(view As B4XView) As B4XPageInfo
    Dim pi As B4XPageInfo = Null
    Do While view.IsInitialized And pi = Null
        pi = B4XPages.GetManager.GetPageInfoFromRoot(view)
        view = view.Parent
    Loop
    Return pi
End Sub

But then what can you do with it?

You can only get a generic object, without having access to its properties and methods.

You should cast it to the correct type:

Dim pg As MyPage187 = pi.B4XPage

Dim pg As MyPage187 = pi.B4XPage

Yes but @Alessandro71 doesn't know what it is

The OP wanted to get the B4XPage object. This is the answer.

Maybe he wants to raise an event?

CallSubDelayed(pi.B4XPage, "NonStandardEventAsWeDontKnowTheEventName")

 

[Alessandro71]

this was actually for the Initialize of the Camera object for B4i in a cross-platform project

    Dim p As B4XPageInfo = B4XUtils.GetPageInfoFromView(mBase)
    Private Camera As Camera
    Camera.Initialize("Camera", B4XPages.GetNativeParent(p.B4XPage))

 

[Alessandro71]

Public Sub GetPageInfoFromView(view As B4XView) As B4XPageInfo
    Do While True
        Dim pi As B4XPageInfo = B4XPages.GetManager.GetPageInfoFromRoot(view)
        If pi <> Null Then
            Return pi
        Else
            view = view.Parent
        End If
    Loop
    Return Null
End Sub

the above code, which I put in a code module, while no errors are displayed in the IDE, produces the following message in the compilation phase:

Compiling generated Java code. Error
B4A line: 123
view = view.Parent
src\com\project\check\pro\test\b4xutils.java:69: error: unreachable statement
;

I've updated the code. It should fix it.

O.T. I know by "OP" you mean who opened the thread but what does OP stand for? (Just out of curiosity since I prefer to mention the nickname directly, it's much friendlier)
