Feature Request: keep the size after a nearby dock area was closed

[Wing-summer]

Hello! I am the author of WingHexExplorer2. I use your qt ads as my docking system. I have a question about the policy as the title says:

Above as the image I want to demostrate the problem: I want to keep the size of the dock widget "日志" after the close of "WingHexExplorer2.exe : 1" ("WingHexExplorer2.exe" is added to the centeral dock widget area).

I have read your dev document but I find nothing to solve the problem. Can you give me some tips? Thanks!

This is not so easy to implement, but you can try to do it in your application. You need to somehow keep track of the size of the window that should not change its size. When a dock widget is closed/hidden, you can access its parent DockSplitter and the use the setSizes() function to adjust the sizes of the single widgets in the splitter.
