[FIXED] Swing & JavaFX: how to convert JavaFX MouseEvent to Swing MouseEvent?

Issue

The package SwingUtilities has a nice function, convertMouseEvent, to convert a mouse event on a component to a mouse event on another component:

MouseEvent convertedEvent = SwingUtilities.convertMouseEvent(originalComponent, event, otherComponent);

Meanwhile, the MouseEvent in JavaFX has a method copyFor to create a copy of the MouseEvent for another component:

MouseEvent convertedEvent = e.copyFor(e.getSource(), otherComponent);

I would like to do something similar to convert a JavaFx MouseEvent e to a Swing mouse event.

I couldn't find a baked in function, so I tried to write my own. There are two fields I can't readily convert though:

• Id field that identifies the event. I assume I'll have to manually convert from e.getEventType().getEventType().getName()
• In JavaFX there is no "when" property indicating when the event occurred. It seems I could use the current system time here
• The modifier of the mouse event. I'm not sure how to build those from the properties of the JavaFX event

Is there a way to get the modifier from the properties of e?

Solution

The functions in SwingEvents can be useful. They can be accessed with the import

import com.sun.javafx.embed.swing.SwingEvents;

To convert from JavaFX to Swing:

SwingEvents.fxMouseButtonToMouseButton(fxEvent): converts a JavaFX event to a Swing mouse button.

SwingEvents.fxMouseEventTypeToMouseID(fxEvent): converts a JavaFX event to a Swing mouse ID.

SwingEvents.fxMouseModsToMouseMods(fxEvent): converts a JavaFX event to Swing mods.

To convert from Swing to JavaFX:

SwingEvents.mouseIDToEmbedMouseType(swingEvent.getID()): converts a Swing mouse event ID to a JavaFX MouseType.

SwingEvents.mouseButtonToEmbedMouseButton(swingEvent.getButton, swingEvent.getModifiersEx()): converts a Swing mouse button to a JavaFX mouse button. Currently bugged (JDK-8242419).
