Android Question [Solved] B4XView.SelectionStart

Roger Daley · Dec 14, 2020

Hi All,

In B4A this works:

B4X:

'Display1 created in Designer'
Private Display1 as EditText
Display1.SelectionStart = Display1.Text.Length

When Display1 is declared as B4XView it flags "Unknown member: selectionstart"

B4X:

'Display1 created in Designer'
Private Display1 as B4XView
Display1.SelectionStart = Display1.Text.Length

It seems too simple to go wrong, but..........

Help would be much appreciated.

Regards Roger

When a member does not exist (property or method) you have to use the original view.

B4X:

    #If B4A
       Dim Disp1 As EditText = Display1
    #Else If B4J
       Dim Disp1 As TextField = Display1
    #Else If B4I
       ' I don't know, not having B4I; it should be the same of B4J
    #End If
    Disp1.SelectionStart = Disp1.Text.Length

You are right to be surprised: I had forgotten a "l", but now I have corrected ?

LucaMs,
Amazing, you've given me the answer but not one I would have ever had guessed.

Many Thanks Roger.
