how to create window in frame and drag windows like eclipse

[mary zhang]

Hi Everyone

I am learning to create the program editor which is similar like Crimson Editor. I noticed there are windows in the frame. There are directory window and output window and main window. The window could be dragged and moved.

Could anyone kindly tell me what kind of API or component could be used to make window in frame and dragged freely?

I appreciate if anyone could reply ASAP.

Thanks a lot and have a good day
