B4J Question [B4X] Problem with B4XView iteration of (UI) components

[CryoGenID]

Dear fellow developers,

I have a problem and hope that you can help me

I am trying to interate through all UI components in my current view and change some settings (e.g. colors).
It works great with Buttons and Labels in B4J and B4i (B4A not tested yet) but I also have a B4XFloatTextField and that is not being recognized by my "else if" clause...
(What) would I need to do different that I can check if the current B4XView (variable "v" in my example) is a B4XFloatTextField and do my changes?

For j = 0 To b4xviewIn.NumberOfViews-1
Dim v As B4XView = b4xviewIn.GetView(j)
If v Is Button Then
v.Text = "TestButton"
Else if v Is Label Then
v.Text = "TestLabel"
Else if v Is B4XFloatTextField Then
v.EditTextHint = "TestB4XFloatTextField"
End If
Next

Thanks so much in advance!

Best regards,

Chris

        Dim v As B4XView = b4xviewIn.GetView(j)
        If v Is Button Then
            v.Text = "TestButton"
        Else if v Is Label Then
            v.Text = "TestLabel"
        Else if v.Tag Is B4XFloatTextField Then
            Dim FTF As B4XFloatTextField = v.Tag
            FTF.HintText = "TestB4XFloatTextField"
            FTF.Update
        End If
    Next

Thanks Luca for your reply!

That worked beautifully!
THANKS!

One question though:
Do I need to get the types of the B4X.... - components always via the tag-attribute?

Thanks and best regards,

Chris

Do I need to get the types of the B4X.... - components always via the tag-attribute?

yes, if it is a custom control

Do I need to get the types of the B4X.... - components always via the tag-attribute?

Only if...

To solve this problem the following convention is used in all XUI Views and is recommended for all new custom views:
The class instance is set to the base panel Tag property.
