Debugging – how to use scenicview to check subwindows (contextmenus, popupcontrols, etc.)

Using scenicview, I want to be able to check the inside of ContextMenu or combobox, but (because they should) they will disappear before the check occurs:

In addition to changing the behavior of each control will not disappear, is there a way to freeze things so that you can check these controls using scenebuilder?

Here's a sscce, for anyone willing to jump

Solution

I realized it was out of date, but I also encountered this problem I have a partial answer:

contextMenu.autoHideproperty().set(false);

The menu will remain unchanged However, it seems that scenicview will refuse to actually check the menu
