JavaFX: Allow window resizing in one direction only

Question

One can change the resizeable state of a JavaFX stage using javafx.stage.Stage.setResizable(boolean) method.

QUESTION

Is there any possibility to allow resize only horizontally or only vertically?

---

There are methods like Stage.setMaxWidth , Stage.setMaxHeight , Stage.setMinWidth , Stage.setMinHeight but they can only be used to control resizing with fixed sized stages (by setting width = minWidth = maxWidth for example, to disallow horizontal resizing).

Answer 1

You can prevent external attempts to change height like this:

stage.show();
stage.maxHeightProperty().bind(stage.heightProperty());
stage.minHeightProperty().bind(stage.heightProperty());

Same for width:

stage.maxWidthProperty().bind(stage.widthProperty());
stage.minWidthProperty().bind(stage.widthProperty());

This way will give you the ability to resize it internally when the content changes (call sizeToScene() for example).
