Computes the minimum height of this region. Returns the sum of the top and bottom insets by default. Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a HORIZONTAL content bias, then the width parameter can be ignored.

Doc from javafx.scene.layout.Region.computeMinWidth.

Computes the minimum width of this region.

If the subclass doesn't have a VERTICAL content bias, then the height parameter can be ignored.

Annotations

Doc from javafx.scene.layout.Region.computePrefHeight.

Computes the preferred height of this region for the given width; Region subclasses should override this method to return an appropriate value based on their content and layout strategy. If the subclass doesn't have a HORIZONTAL content bias, then the width parameter can be ignored.

Annotations

back to summary

protected double computePrefWidth(double height)

Overrides javafx.scene.layout.Region.computePrefWidth.

Doc from javafx.scene.layout.Region.computePrefWidth.

Annotations

@Override

getChildren back to summary

protected ObservableList<Node> getChildren()

Overrides javafx.scene.Parent.getChildren.

Doc from javafx.scene.Parent.getChildren.

Gets the list of children of this Parent.

See the class documentation for Node for scene graph structure restrictions on setting a Parent's children list. If these restrictions are violated by a change to the list of children, the change is ignored and the previous value of the children list is restored. An IllegalArgumentException is thrown in this case.

If this Parent node is attached to a Scene attached to a Window, that is, showing (javafx.stage.Window#isShowing()), then its list of children must only be modified on the JavaFX Application Thread. An IllegalStateException is thrown if this restriction is violated.

Note to subclasses: if you override this method, you must return from your implementation the result of calling this super method. The actual list instance returned from any getChildren() implementation must be the list owned and managed by this Parent. The only typical purpose for overriding this method is to promote the method to be public.

Annotations

Returns the orientation of a node's resizing bias for layout purposes. If the node type has no bias, returns null. If the node is resizable and it's height depends on its width, returns HORIZONTAL, else if its width depends on its height, returns VERTICAL.

Resizable subclasses should override this method to return an appropriate value.
