    [4.2.0 beta 2] It would be great to have a tree's beforecheckchange event


    Hello ExtJS team,

    Many events have its "before" counterparts and it is cool.

    It would be great to have a "beforecheckchange" event for a tree as well. For example, to prevent check/uncheck by returning false.

    Also a property for a node like "checkReadOnly" would be also excellent.

    Thank you for your attention.

    P.S. I noticed "Thank you for reporting this bug." after starting the thread. I thought this forum is for any topic related to beta. But seems not. So, it was a wrong place for a feature request, apologize.
