tooltip

问题 I am having difficulties making the Material UI tooltip actually appear when hovering over a component. As far as I can tell, I am doing about the simplest implementation of the tooltip component: I import it directly (no custom styles or anything else yet), and I wrap it around another component that spreads out its props at the top level.

问题 I have a requirement to not have the standard .NET Windows Forms tooltip automatcially hide - that is, I need them to remain visible until the mouse moves off the control that has the tooltip.

问题 In JavaFX subclasses of Control have a tooltip property which means that one can declaratively add a Tooltip using FXML thusly: <CheckBox fx:id="someCheckBox" mnemonicParsing="false" text="Do It?"> <tooltip> <Tooltip text="Whether or not to do it."/> </tooltip> </CheckBox> This is possible only because CheckBox is a subclass of Control. However, I would like to be able to add a tooltip to any scene-graph Node using FXML (i.e. without having to programatically add the tooltip using Java). 回答1:
