Disable action area of SplitMenuButton, but not drop down menu

a_pabst

Is there a way to achieve this?

Using setDisable(true) deactivates the entire control.

I want the drop down menu items to still be accessible, but the action area visibly inactive.

I am presuming you want the button part (left side of the control) to look disabled while the arrow-button (right side) looks active?

In which case, you could use CSS to achieve this effect. Here is a quick sample which you can fine tune:

.my-split-menu-button > .label {
 -fx-opacity: 0.4;
}
.my-split-menu-button > .label:hover {
    -fx-color: -fx-base;
}

Thanks for your suggestion.

It should not only look disabled, but also behave like a disabled button, i.e. be inactive.

Besides, it should work dynamically. I can of course add and remove a style class or a custom pseudoclass, but I had hoped there would be a less hacky way.

I don't think SplitMenuButton enables to do that.

May be you should use another UI design.

Or you also may file a feature request for SplitMenuButton.

You might be able to do this by adding a mouse event _filter_ to the SplitMenuButton. If the target of the mouse event is the Node that is the arrow-button (one way is to check target.getStyleClass().contains("arrow-button"), then pass the event on; otherwise consume the event.
