Generic Enter key shortcut listener

Flow
1

For Vaadin 8 I had a utility that essentially took a HasChildren (often a Layout), iterated throw the children and kept track of those that were Focusable and then used a generic ShortcutAction that handled focusing of components based on certain rules when the enter key was pressed. How would such a utility be written in Flow (12)? I noticed that e.g. TextFields could have key listeners but how to handle the generic case?

Thanks in advance,
Nik

Hi Nicklas,

Does this help?

It’s for Vaadin 13, but shouldn’t be hard to change to this version.

Thanks, it looks promising. Might as well jump to the 13-line since I’m prototyping for a new application…

Hi, is the correct behavior, press shortcut key twice, then only login?

Shortcuts.addShortcutListener(loginPanel, loginBttn::click, Key.ENTER);

There’s a special case with using Enter as the shortcut key that also requires you to use .allowBrowserDefault() on the shortcut registration.
