Sometimes, it will depend on the circumstances: In the following managed layouts, that means objects will still be arranged around your button: Just setting the visible property on a button will remove it from view, but not from the layout. The setVisible() method is designed to allow developers to rapidly add or remove nodes from view without having to recache the object in the program’s running memory. Setting the opacity property will cause the background JavaFX rendering logic to re-calculate all the rendering requirements for that node. They won’t respond to input by either the keyboard, or the mouse.Ī quick note on performance: Setting the node visibility is much more performance-friendly than manually setting the opacity of an object. tVisible(false) īuttons that are invisible can’t be interacted with by the user. Passing the boolean value false will have the effect of making the button completely invisible. The simplest way to hide a button from the display is to invoke setVisible() on the button object. I’ll go through each of these one by one and you can work out which one you want to 1. Disable a button without removing it from display.Animate the disappearance using transitions.
Set visible and managed properties to false.Finally, you can disable a button, to lock it from user input without removing it from the display. On top of that, you can animate the visibility of your button to remove it from your display in a visually-appealing way. To uncouple the button from the layout’s position calculations, developers can additionally setManaged(false). The button will still maintain its position and other nodes may still be arranged around it. To hide a button in JavaFX, setVisible(false) should be invoked on the button object to remove it from view. If an action isn’t possible, or can’t be completed because of the state of other components in the scene, hiding a button can be a useful way to prompt further user input. Sometimes you just want to limit a user’s options.
