JavaFX Make an object visible but not consume (ignore) clicks

Question

The title says it all: I have a rectangle in JavaFX (for transparency / opacity), but I want people to be able to “click” it.

Therefore, when I say “click”, I mean that when you click on it, Java should pretend that it is not there, and instead of “click” on what is under this object. When you do something invisible with setVisible (false), this is exactly what happens - any object that you set invisible does not consume the click events that your mouse generates. However, the object becomes invisible - I do not need something.

Is it possible? Thanks for any help you can provide!

Answer 1

All Node in JavaFX have the setMouseTransparent() method, as described in here , where the mouseTransparent property mouseTransparent :

If true, this node (along with all its children) is completely transparent to mouse events. When choosing a target for a mouse event, nodes with mouseTransparent set to true and their subtrees will not be taken into account.

If you need more complex mouse transparency effects, such as having only the parent node, can be transparent, you may need to combine this with another click detection method ( its name speeds me up at the moment. I think it was pickOnBounds , and in order to use it, I can’t say for sure, I think I abused it more, setting literally everything in my application as true or false , but I don’t remember which one, and, unfortunately, I couldn’t tell you which nodes you need to install for this properties), but for simple mouse transparency that should work.
