B4J Question Hover event on panes

[Cableguy]

Hi EREL, (I know I shouldn't limit my question to one single user, but anyone else is also free to answer)

Is there an Hover event for any node in b4J? Specially for Pane, Image and canvas nodes?

I found this info, can it be hoocked with inline java?

Doing some trying out, I found that MouseMoved event can be used as a Mouse_Entered event.... Now I would need to have a mouse_exited event!

You can add onMouseEntered and onMouseExited to any node as far as I know.

...
        MouseOver(b(a))
        Next  
End Sub
Sub MouseOver(n1 As Node)
        setHandler(n1,"setOnMouseEntered","mouseIn")
        setHandler(n1,"setOnMouseExited","mouseOut")
End Sub
Sub setHandler(ob As JavaObject,eventName As String,handlerName As String)
ob.RunMethod(eventName, Array(ob.CreateEventFromUI("javafx.event.EventHandler",handlerName,True)))
End Sub
Sub mouseIn_Event(m As String,args() As Object)
    Log("In "& asJO(Sender).RunMethod("getId",Null))
End Sub
Sub mouseOut_Event(m As String,args() As Object)
    Log("Out "& asJO(Sender).RunMethod("getId",Null))
End Sub
Sub asJO(o As JavaObject) As JavaObject
    Return o
End Sub

Works perfect for nodes... Thanks @Daestrum

Is it possible to have the same events for forms?

 

[Daestrum]

You can use Mainform.Rootpane as the node.
It wont detect when user hovers over the window title bar though, only when they enter/leave the rootpane area of the form.

With risk to feel intimidated by my question, I want to ask what's the ... command in the example? Dim a as ImageView? that's for my need at least. Cheers

Small example using the subs of Daestrum.
