Slate SNew : change created objects in events

[anonymous_user_f881c5ba]

Hi,
I have :

SNew(SImage)
    .Image(myFSlateBrush)
    .OnMouseButtonDown_Lambda([this,args](const FGeometry&, const FPointerEvent&)
	{
        ...
        //here I would like to change the .Image
         })

How to change the image of the SImage in the lambda function “.OnMouseButtonDown_Lambda”?

More generally, how to call the created object in events functions to do changes on it?
For example :

SNew(SButton)
    .Onclicked_Lambda(...)
    {
        ...
     //here I would like to call "this" button to do things like :
    thisButton->Cursor=...;
    thisButton->ButtonColorAndOpacity=...
     })

Thanks.
