I am facing performance issue due probably to my way for invalidation on data update. I have widget inside container that are not visible. When I have a data change, I update the content of the widget and invalidate the textarea for example. But this text area is not display on the screen as inside an invisible container. However, the region is still redrawn.
Was is the best way to avoid that ? Is there a way for the widget to know if somehow it is really displayed or not ? I often use container to avoir set visible to false a lot of widget that are working together. so the widget visible property is set to true. it's "parent is not" or the parent of the parent is not.
Hope you can help me about that.
regards
