TextArea does not handle MouseEvent.MOUSE_PRESSED

问题

I am building a JavaFX application and I have a TextArea inserted.
The TextArea has a CSS class assigned (don't know if it matters):

.default-cursor{
    -fx-background-color:#EEEEEE;
    -fx-cursor:default;
}

There are 2 issues about this TextArea:

1. -fx-cursor:default; Has no effect as the cursor remains the text cursor. That is weird as i use the same class for a TextField with proper/expected results

2. The TextArea does not handle MOUSE_PRESSED event
   My code is :

   textArea.addEventHandler(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>() { @Override public void handle(MouseEvent event) { System.out.println("print message"); } });

Any ideas Why?
I want to note that when I changed EventHanler to handle MOUSE_CLICKED everything is fine

回答1:

I suspect the default handlers for mouse events on the TextArea are consuming the mouse pressed event before it gets to your handler.

Install an EventFilter instead:

textArea.addEventFilter(MouseEvent.MOUSE_PRESSED, new EventHandler<MouseEvent>() {
            @Override
            public void handle(MouseEvent event) {
                System.out.println("mouse pressed");
            }
        });

The Event filter will get processed before the default handlers see the event.

For your css issue, try

.default-cursor .content {
  -fx-cursor: default ;
}
