How to change behavior of text fields

[tobiasdiez]

With Java 8, we used a custom TextFieldSkin to add a few custom options to the context menu of a text field. In more recent Java versions, the relevant code now moved to TextInputControlBehavior.

openjdk-jfx/modules/javafx.controls/src/main/java/com/sun/javafx/scene/control/behavior/TextInputControlBehavior.java

Line 661 in 662281e

protected void populateContextMenu() {

Thus, it would be simple to derive from this behavior class and add additional items to the context menu. However, I don't see a way to replace the original behavior by the customized one, because the behavior is initialized here:

openjdk-jfx/modules/javafx.controls/src/main/java/javafx/scene/control/skin/TextFieldSkin.java

Lines 151 to 154 in 4f0addf

	this.behavior = (control instanceof PasswordField)
	? new PasswordFieldBehavior((PasswordField)control)
	: new TextFieldBehavior(control);
	this.behavior.setTextFieldSkin(this);

and behavior in TextFieldSkin is private. Thus, there seems to be no easy way to register a custom behavior class. Did I overlooked something obvious?
