Copy the text of the textfield into it's tooltip, then when you hover over it the tooltip will show the full path.

The only way I could find to display the tail of the text is a bit of a hack, I couldn't find any methods to help. You could easily wrap it into a customview. The full text is stored in the textfields tag.

I found a few links about text alignment, using CSS, but trying them did not have the expected results.
The tooltip hack is quite a good idea

You can bind the textfield.text value to the tooltip.text so they are always in sync without the need to change the tooltip text in textfield.textchanged event.
Using javaobject

B4X:

...
asJO(tf).RunMethodJO("textProperty",Null).RunMethod("bindBidirectional",Array(asJO(tf).RunMethodJO("getTooltip",Null).RunMethodJO("textProperty",Null)))
...
Sub asJO(o As JavaObject)As JavaObject
Return o
End Sub

Edit: Oops forgot to add - tf is the textfield

You can show the path in a label and set its elllipsize mode by adding this to the Extra CSS field:

B4X:

 -fx-text-overrun: leading-ellipsis ;

I have found that adding the css in the designer has no effect, and adding it in code using TextField.Style overruns all my previous css styling rendering the view in default css visualy!

It works with labels, not TextFields.

You should never set the Style property directly. Use CSSUtils to set a property instead.

I get the same result, but I decided to solve the original question the hard way and created a small sub to trim a passed string to length

B4X:

Private Sub TextToRight (Text As String) As String
    If Text.Length < 40 Then Return Text
    Dim newText As String  = Text.SubString2(Text.Length - 40, Text.Length)
    newText =".." & newText.SubString(newText.IndexOf("\"))
    Return newText
End Sub

.
