I'm somewhat confused. Got some code that we can see that demonstrates
the problem?

Class uiTreeCtrl is declared as:
class uiTreeCtrl : public CTreeCtrl, public uiWnd {
public:
uiTreeCtrl();
....
protected:
afx_msg void OnSelChanged(NMHDR* pNMHDR, LRESULT* pRes);
....
}
In the implementation following message mapping is done
BEGIN_MESSAGE_MAP(uiTreeCtrl, CTreeCtrl)
ON_NOTIFY_REFLECT(TVN_SELCHANGED, OnSelChanged)
....
END_MESSAGE_MAP()
uiTreeWorkShell is declared as:
class uiTreeWorkShell : public uiWorkShell {
public:
....
protected:
CTreeCtrl the_cTreeCtr;
....
afx_msg void OnSelChanged(NMHDR* pNotifyStruct, LRESULT* pResult);
....
}
in the implementation following mapping is done:
BEGIN_MESSAGE_MAP(uiTreeWorkShell, uiWorkShell)
ON_NOTIFY(TVN_SELCHANGED,ID_TREECTRL,OnSelChanged)
END_MESSAGE_MAP()
ID_TREECTRL is the ID used to create the the_cTreeCtrl object.
So, when the selection in the tree the_cTreeCtrl changes
uiTreeWorkShell::OnSelChanged() gets called.
I am trying to use uiTreeCtrl object instead of CTreeCtrl,
On doing so, when the tree selection changes, only uiTreeCtrl::OnSelChanged()
is called, uiTreeWorkShell::OnSelChanged() never gets called.
What I want is that both the fuctions should be mapped to the event, and both
of them must be called.
Thanks,
chetan.
