[External] : Re: Q: Labeled.textTruncated Property (RFE)

[Andy Goryachev]

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



Pull Request: https://github.com/openjdk/jfx/pull/1389<https://urldefense.com/v3/__https:/github.com/openjdk/jfx/pull/1389__;!!ACWV5N9M2RV99hQ!LUwCrjMEKxlGC0k5v9-zO0Axw6TqddmMJM7_6onFdHOLL1eo5MDNu1lVj7grGquhgJdnqXX_eCyA7MGEMNyIivVMcBB9XfY$>

What do you think?
