Hi, How can I set label alignment to justify?

www.b4x.com

But this code below and found the same work

LContant.TextAlignment=3

I remained a small problem I want to align be justified and right
The problem you get in the last line where it is back to the left

He did this code and did not work

LContant.TextAlignment=Bit.Or(2,3)

Sub JustifyRTL (cs As CSBuilder) As CSBuilder
    Dim ParaStyle As NativeObject
   ParaStyle = ParaStyle.Initialize("NSMutableParagraphStyle").RunMethod("alloc",Null).RunMethod("init",Null)
    ParaStyle.SetField("alignment",3) 'JUSTIFY
    ParaStyle.SetField("baseWritingDirection", 1) 'RIGHT_TO_LEFT
    cs.As(NativeObject).RunMethod("addAttribute:value:range:", Array("NSParagraphStyle", ParaStyle, cs.As(NativeObject).MakeRange(0, cs.Length)))
    Return cs
End Sub

Thank
But why shows so

 

[Erel]

This is the new inline casting feature (B4i v7.50). Use Dim no As NativeObject = cs

Check the code carefully. It should work. If not, update the small project and upload it again.

You are correct. It should be:

    ParaStyle = ParaStyle.Initialize("NSMutableParagraphStyle").RunMethod("alloc",Null).RunMethod("init",Null)

 

[Erel]

Note that it will override the center alignment that you set in the CSBuilder. You can modify the range, MakeRange(0, cs.Length) to make it skip the beginning.

It works now but I ignore CSBuilder format

You modified it to 1
But he appears at the beginning of it
Then closes the program and shows this error

MakeRange(1, cs.Length)

NSMutableRLEArray objectAtIndex:effectiveRange:: Out of bounds

 

[Erel]

That's expected. You need something like: MakeRange(7, cs.Length - 7).

 

[AlfaizDev]

That's expected. You need something like: MakeRange(7, cs.Length - 7).

He works now but still ignores CSBuilder format
Color

thanks
