Android Question [B4X] B4XFloatTextField - hide password in code.

[MrKim]

I have a b4xpage that displays, among other things, a password. I am using the feature that allows you to view the password. Unfortunately the next time you open that page the password is still visible.

I would like to hide the password in code - in B4A/J/i. I looked for a property but couldn't find one.

Thanks for any help.

Have you tried to get the native control and check that ? B4A is a text field.

I would like to hide the password in code - in B4A/J/i. I looked for a property but couldn't find one.

Dim et As EditText=B4XFloatTextField1.TextField
et.PasswordMode=True  'it will hide the reveal

 

[LucaMs]

Dim et As EditText=B4XFloatTextField1.TextField
et.PasswordMode=True  'it will hide the reveal

Yes, I was trying but I encountered a wall: it seems that in B4J the TextFields can be created of "type" password by code but I don't see the way to convert a B4XView into a TextField with password.

[... and I don't know B4i]

 

[LucaMs]

'it will hide the reveal

That's another major problem.

BTW, you can write that code:

Dim et As EditText=B4XFloatTextField1.TextField
et.PasswordMode=True  'it will hide the reveal

so:

B4XFloatTextField1.TextField.As(EditText).PasswordMode = True

thanks to the new feature "As".

However I did not understand the question.


You have a B4XFloatTextField; click the reveal button to be able to read the password. So you open another page and when you go back to the first you want the password to be "hidden" again. How come???

Have considered using two identical views on top of each other. Only one is visible. One has a password reveal, the other doesn't.
You can then control which one you want to show at what time. When focus is lost, copy text to the alternative view.

Note, I did look at the source code for B4XFloatTextfield (Anywhere, Internal library, XUI View.B4XLib). The internal switch to determine reveal or hide occurs in multiple places, so a simple modification is not in the cards.

I do see the need for this effect. After leaving a field, it is reassuring that the password is hidden again. It also let's you force one-time entry of password.

Correction: I modified B4XFloatText to make SwitchFromPasswordToRegular Public, and changed the name to ModB4XFloatTextfield.

Sub Class_Globals
    Private Root As B4XView
    Private xui As XUI
    Private ModFloatTextField1 As ModFloatTextField
   
    Private passwordEntered As Boolean
End Sub

Public Sub Initialize
End Sub

Private Sub B4XPage_Created (Root1 As B4XView)
    Root = Root1
    Root.LoadLayout("MainPage")
End Sub

Private Sub Button1_Click
    xui.MsgboxAsync("Hello world!", "B4X")
End Sub

Private Sub ModFloatTextField1_FocusChanged(hasFocus As Boolean)
    If hasFocus = False Or passwordEntered Then
        ModFloatTextField1.SwitchFromPasswordToRegular(False)
        passwordEntered = True
    End If
End Sub

Add the attached file to the parent directory in a B4XPages project and add as existing module to the project.

see B4X:

Private Sub B4XPage_Disappear
    Log("LoginPage: B4XPage_Disappear")
    CallSub2(txtUserPaword, "SwitchFromPasswordToRegular", False)
End Sub

 

[TILogistic]

incorrect:

use:

CallSub2(txtUserPaword, "SwitchFromPasswordToRegular", False)

 

[William Lancee]

@oparra I never thought of accessing private methods using CallSub. Very nice!

 

[Mahares]

CallSub2(txtUserPaword, "SwitchFromPasswordToRegular", False)

Is this a hack or a workaround. How does one know that there is such sub named: SwitchFromPasswordToRegular in the B4XFloatTextField class module without actually unzipping and sifting through its code in the XUI Views library. Is there a more intuitive way to manipulate the password. It is nevertheless better than creating a new class: ModFloatTextField

No.
is a solution

you can use or modify these tools, to see the events and functions of B4XLib.

Attached you find a B4x Help Viewer. The original program was written by Andrew Graham (agraham) for B4A with Basic4PPC desktop. Andrew is no more active in the forum and some time ago I asked him if I could get the source code to adapt it if needed. I have been using this program since the...

The user has access to lots of passwords for multiple sources. when he "Closes" the page he may be opening another page to a completely different source with a different password. There is the possibility that one pw is quite sensitive, and another, not so much. He might have someone looking over his shoulder and he is fine with that person seeing one PW - perhaps he is giving it to them. The next one he opens - no. The user may have looked at the screen when no one was in the room with him, the next time, someone else is there. He could be opening the page to give someone information other than the password, ie. web address/address/phone number.
