child tool window should not be closed when base tool window is closed

Hi Maddy,

Sorry this is a bit of a complex scenario and would help if you provided us with a simple sample project showing it.  But in general, if you are nesting DockSites, which it sounds like you are doing, then closing a tool window that contains the nested DockSite will close tool windows from the nested DockSite.  That is by design and can't really be worked around.  If you don't like that behavior then you shouldn't use a nested DockSite design.

Okkay I do agree.

The  child tool window which I have floated earlier is being closed only on closing the base tool window.

So can I save the state of that tool window and again childToolWindow.Float(locationOfToolWindow, sizeOfToolwindow) can locate the position of that child window at the same location.

Hi Maddy,

You could do that but it would probably be easier to use our layout serialization feature to save the layout and restore it again later.  Layout serialization is described in the documentation and there are some examples in the samples too.

But again it is attached with the parent docksite or parent Tool window. I am able to do this, when it comes to a single tool window. But here I have a case of multiple parent child tool window as I explained earlier. So whenever I close the main tool window,childToolWindow.Float(locationOfToolWindow, sizeOfToolwindow) can not retain the existence of child tool window at the area whereever it was floated initially.

If I understand correctly and your tool window you are closing has a nested DockSite that contains other floating child tool windows, then those child tool windows will close when the main root tool window is closed.  There is no workaround for that since the nested DockSite is being removed, due to its containing tool window being closed.  If you don't want the rafted inner tool windows to close then you'd need to move them to another DockSite that is remaining open.
