Restore Autohidden ToolWindowContainers

I wrote the following test code to try autohide and dock (restore) ToolWindowContainers. My test code creates three ToolWindowContainers by “Create Windows” button, and “Auto Hide Windows” button hides two of them. The purpose of this code is to enlarge one of ToolWindowContainers as necessary, and “Restore Windows” button is intended to restore the layouts of three ToolWindowContainers.

                twc.Dock();
            }
        }
    }
}

“Restore Windows” button calls “Dock” method for each ToolWindowContainer, but three ToolWindowContainers are not restored. I also tried to use DockSiteLayoutSerializer, but it didn’t work as well.

My question is how to restore the layout of ToolWindowContainers after Autohide. Or, if you have different ways to enlarge one of ToolWindowContainer and restore the layout, please let me know.

I'm a beginner C# programmer, so I'm sorry if this is a simplistic question.
