Is it possible to change the parent of a composite in RAP via the setParent() method? I tried, but it returns false. Any workaround?

I am using WindowsBuilder for designing my Views. I just drag and drop it to that parent. Then I get the code generated Wink

.

But I don't know anything about Reparenting Rolling Eyes

The short answer is: no

isReparentable() -> false

But what's your use case, or what did you have in mind? Maybe you can describe your problem and there's another solution for it.

The use case is rather straightforward. It is basically an attempt to achieve a StackPanel (GWT) - like widget

http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/StackPanel.html

within RAP. Imagine 55 rectangular boxes with stock market bid/ask quotes, each of which can be expanded on mouse click. The expanded client area is a composite showing some data. The user can arbitrarily expand and collapse such boxes.

What I want is a single client area that can be simply reparented to the appropriate expanded widget and initialized instead of being destroyed and recreated each time. It would be awesome if I could also use ClientScripting for that task Smile
