Swing & JavaFX: how to convert JavaFX MouseEvent to Swing MouseEvent?

问题

`SwingUtilities`包中有一个很好的函数，`convertMouseEvent`，用于将组件上的鼠标事件转换为另一个组件上的鼠标事件：

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

与此同时，JavaFX中的MouseEvent有一个名为copyFor的方法，用于为另一个组件创建MouseEvent的副本：

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

我想做类似的事情，将JavaFx的MouseEvent e转换为Swing鼠标事件。

我找不到现成的函数，所以我尝试编写自己的函数。但有两个字段我不能轻易转换：

• 用于标识事件的Id字段。我猜我需要手动从e.getEventType().getEventType().getName()进行转换。
• 在JavaFX中，没有指示事件发生时间的"when"属性。在这里，我似乎可以使用当前系统时间。
• 鼠标事件的修饰符。我不确定如何从JavaFX事件的属性构建这些修饰符。

是否有办法从e的属性中获取修饰符？

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

```java
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?

SwingEvents 中的函数可能很有用。 可以通过以下导入进行访问：

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

从 JavaFX 转换到 Swing：

SwingEvents.fxMouseButtonToMouseButton(fxEvent)：将 JavaFX 事件转换为 Swing 鼠标按钮。

SwingEvents.fxMouseEventTypeToMouseID(fxEvent)：将 JavaFX 事件转换为 Swing 鼠标 ID。

SwingEvents.fxMouseModsToMouseMods(fxEvent)：将 JavaFX 事件转换为 Swing 修饰键。

从 Swing 转换到 JavaFX：

SwingEvents.mouseIDToEmbedMouseType(swingEvent.getID())：将 Swing 鼠标事件 ID 转换为 JavaFX MouseType。

SwingEvents.mouseButtonToEmbedMouseButton(swingEvent.getButton, swingEvent.getModifiersEx())：将 Swing 鼠标按钮转换为 JavaFX 鼠标按钮。目前存在错误（JDK-8242419）。

英文:

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).
