In JavaFX, if I have a scene with 2 VBox
elements and each VBox
has multiple Label
in it.
If I set the top VBox
to invisible, why does the bottom VBox
not move up the scene where the top VBox
was ?
The VBox
is invisible but I would expect the other objects to move into its place.
I am using FXML to load my controls.
Node.setVisible(boolean)
just toggles the visibility state of a Node
.
To exclude a Node
from its parents layout calculations you additionally have to set its managed state, by calling Node.setManaged(false)
.
If you want the managed state to be updated automatically alongside the visibility, you can use a binding as @jewelsea pointed out: node.managedProperty().bind(node.visibleProperty());
Since it's invisible, it wont move to the top. You have to remove it with something like:
// remove
vbox.getChildren().remove(...)
Once you've removed the element you want invisible then, the other element should move to the top.
Try to use setVisible and managedProperty together. Here is an example:
myHBox.setVisible(false);
myHBox.managedProperty().bind(myHBox.visibleProperty());
Instead of hiding the vbox you should remove it from the Children and if you want to show it again add the vbox again.
