Splitter window and Tree View

I'm trying to figure out how to route the windows messages in the following scenario.

I have the following classes
CWLSFrame - This frame handles create a static splitter window.  There are only two windows.  The left window is assigned the my CWLSTreeView class, and the right window is assigned to my CWLSEntityView class.

CWLSTreeView - This class takes care of the TreeCtrl and inserts items into the tree.  It also receives the message when the user changes the currently selected tree item.

CWLSEntityView - A generic view class of the Tree.

CWLSSoundView - When the user selects a "sound item" in the tree, I want it to use this view.

I understand how to manipulate the above classes into the different views.  My question is, when a user changes their selection in the Tree.  How can I get this message to the CWLSFrame so that it can change the splitter window?

Thanks in advance

In your case CWLSFrame is the parent frame of CWLSTreeView, hence you can do this :

1. Handle the TVN_SELCHANGED reflected message in your tree control class member of the TreeView

2. In the handler, which will most probably be OnSelChanged, make a call to GetParentFrame () and type cast the result with (CWLSFrame *) to get a pointer to the parent frame window, say pWLSFrame

3. Add an user defined message, say WM_CHANGESPLITTER (message to change your splitter) to the CWLSFrame class and a handler for the same. Put your 'splitter change' functionality in the handler sunction.

4. Send WM_CHANGESPLITTER message from OnSelChanged handler of the tree control, using

pWLSFrame->SendMessage (WM_CHANGESPLITTER, (WPARAM) 0, (LPARAM)0)

which should call your WM_CHANGESPLITTER handler (say OnChangeSplitter) in CWLSFrame.
