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 @Override

isContextMenuEnabled	back to summary

isResizable

back to summary

public boolean isResizable()

Overrides javafx.scene.Node.isResizable.

Doc from javafx.scene.Node.isResizable.

Indicates whether this node is a type which can be resized by its parent. If this method returns true, then the parent will resize the node (ideally within its size range) by calling node.resize(width,height) during the layout pass. All Regions, Controls, and WebView are resizable classes which depend on their parents resizing them during layout once all sizing and CSS styling information has been applied.

If this method returns false, then the parent cannot resize it during layout (resize() is a no-op) and it should return its layoutBounds for minimum, preferred, and maximum sizes. Group, Text, and all Shapes are not resizable and hence depend on the application to establish their sizing by setting appropriate properties (e.g. width/height for Rectangle, text on Text, and so on). Non-resizable nodes may still be relocated during layout.

back to summary

public void resize(double width, double height)

Overrides javafx.scene.Node.resize.

Doc from javafx.scene.Node.resize.

If the node is resizable, will set its layout bounds to the specified width and height. If the node is not resizable, this method is a no-op.

This method should generally only be called by parent nodes from their layoutChildren() methods. All Parent classes will automatically resize resizable children, so resizing done directly by the application will be overridden by the node's parent, unless the child is unmanaged.

Parents are responsible for ensuring the width and height values fall within the resizable node's preferred range. The autosize() method may be used if the parent just needs to resize the node to its preferred size.
