JavaFx Text Tooltip mouseover doesn't get any response - javafx

Question

I set a tooltip on a text element in JavaFx, everything works as long as I do not hover mouse on the text, the tooltip does not get displayed.
<Text layoutX="329.0" layoutY="202.0" strokeType="OUTSIDE" strokeWidth="0.0" text="Tcond[C]" textAlignment="CENTER">
<Tooltip text="'%Empty_Bundle'"/>
</Text>
That's the fxml code which should create a tooltip on this text.
How to fix it without creating assign text to an object in my view controller and setting on the tooltip by using .setTooltp() method?

Answer 1

In FXML, if you embed one instance element directly inside another, without a property element, it is used to set the property annotated as the #DefaultProperty on the outer instance element.
If you check the documentation for Text you will see that the default property is "text": so your FXML is equivalent to
<Text layoutX="329.0" layoutY="202.0" strokeType="OUTSIDE" strokeWidth="0.0" text="Tcond[C]" textAlignment="CENTER">
<text>
<Tooltip text="'%Empty_Bundle'"/>
</text>
</Text>
In other words, you are trying to set the text of your Text object to the tooltip.
Text doesn't actually have a setTooltip(...) method at all; that method is defined in the Control class, of which Text is not a subclass. The only way to set a tooltip on a Text instance is by using the Tooltip.installTooltip(...) method, which you can only call from the controller (there is no FXML equivalent to calling this static method).
Your other option, if it works, would be to replace the Text with a Label:
<Label layoutX="329.0" layoutY="202.0" text="Tcond[C]" textAlignment="CENTER">
<tooltip>
<Tooltip text="'%Empty_Bundle'"/>
</tooltip>
</Label>
Note that Label does not allow you to directly configure the stroke, as a Text does, so you would lose that functionality (or at least have to use CSS instead).
