Marius, got your email literally before I could hit "Send" on mine!

You are right, of course, thank you for the effort.

The width of TableCells are bound to the column they belong to.
Therefore, prefWidth(-1) will always return the width of the column and not 
what the cell should ideally have.
See the computePrefWidth() method inside TableCellSkinBase.
There is a flag which unfortunately can not be set: 
isDeferToParentForPrefWidth, which will enable the cell to not take the column 
width but the real preferred width.

Betreff: Re: [External] : Re: Q: Labeled.textTruncated Property (RFE)
Andy, all,

Some comments below:


  1.  Even if it is possible to do the same with public means I think it is 
useful. Anyhow we need to promote the solutions better (e.g., on StackOverflow)

  2.  I tried to achieve what you did in JavaFX core for my use-case, TableView 
cells.

     *   In my real application I tried and failed since the boolean condition 
in 
https://github.com/openjdk/jfx/blob/8a5cb17ed6525b0a218595865ead3e399e3b29dd/modules/javafx.controls/src/main/java/javafx/scene/control/Labeled.java#L838-L841<https://urldefense.com/v3/__https:/github.com/openjdk/jfx/blob/8a5cb17ed6525b0a218595865ead3e399e3b29dd/modules/javafx.controls/src/main/java/javafx/scene/control/Labeled.java*L838-L841__;Iw!!ACWV5N9M2RV99hQ!LOj7jlHaiG3nkCmQXhoTVAmuxuPXZEyedX8Vp_-lnzdcddQfc7VX2u3HLqEW0BghU4TrJFCy650tkuSINaveR80l$>
 always reports false
     *   Hence I tried to create a short self-contained TableView example to 
explore it further, see Gist 
https://gist.github.com/danielpeintner/9b561eb57261e8c5bc608f1346df74cf<https://urldefense.com/v3/__https:/gist.github.com/danielpeintner/9b561eb57261e8c5bc608f1346df74cf__;!!ACWV5N9M2RV99hQ!LOj7jlHaiG3nkCmQXhoTVAmuxuPXZEyedX8Vp_-lnzdcddQfc7VX2u3HLqEW0BghU4TrJFCy650tkuSINXen6EUR$>
It still fails :-(
     *   The Email field in the table ideally should report "true" once the 
text entered exceeds the visible view. Somehow it fails... getWidth() and  
prefWidth(-1) always return the same double value. Please try the Gist above to 
confirm.
e.g., edit cell and extend the email text to longer than column width --> 
results in System.out "Table-Email-Cell !isWrapText: 182.0 < 182.0 --> false"
     *   Hence I also added a *normal* MyLabel example which does work as 
intended
Maybe I miss something obvious but TableCells seem to be special Labeled 
instances and behave differently.

Thanks,

-- Daniel

Dear Daniel:

Thank you for confirming the need for this enhancement.  Your case is covered 
by this ticket (I included a wrong ticket in my previous message by mistake, 
sorry):

JDK-8327483<https://bugs.openjdk.org/browse/JDK-8327483> TreeView: Allow for 
tooltip when cell text is truncated

My only concern is that this functionality theoretically can be achieved by the 
application code just as easy, since the solution does not use any internal 
APIs, as can be seen here: 
https://github.com/openjdk/jfx/pull/1389<https://urldefense.com/v3/__https:/github.com/openjdk/jfx/pull/1389__;!!ACWV5N9M2RV99hQ!LUwCrjMEKxlGC0k5v9-zO0Axw6TqddmMJM7_6onFdHOLL1eo5MDNu1lVj7grGquhgJdnqXX_eCyA7MGEMNyIivVMcBB9XfY$>

Hi Andy, all,

Thank you for the effort which I very much appreciate.
We have a similar use-case as the one mentioned in JDK-8205211.

We would like to show a Tooltip with the corresponding text once the text is 
shown with ellipsis for a TableCell. The *hacky* solution we are using is 
sketched in [1] and requires us to calculate the width again. Moreover, once 
different fonts come into the game it becomes even more brittle.

Having an easy (easier?) way to detect and observe whether a label is truncated 
is of importance for us and definitely improves the usability of JavaFX.

Thanks,

-- Daniel

Dear colleagues:

Do you think a new property, ReadOnlyBooleanProperty textTruncated, should be 
added to the Labeled control?


On one hand, we do have a couple of tickets in JBS requesting that:


  *   JDK-8091891<https://bugs.openjdk.org/browse/JDK-8091891> TreeView: There 
is no tooltip available on truncated node
  *   JDK-8205211<https://bugs.openjdk.org/browse/JDK-8205211> Ability to show 
Tooltip only when text is shown with ellipsis (...)

On the other hand, this functionality can in theory be implemented at the 
application level, although the number of changes required might be 
uncomfortably large in the case of Tree/TreeTable/TableView.

JBS:

  *   JDK-8092102<https://bugs.openjdk.org/browse/JDK-8092102> Labeled: 
truncated property
