Summary: wxTreeListCtrl - add tooltips per row

Initial Comment:
[opened on behalf of Carl Godkin]

I have a suggestion for improving wxTreeListCtrl.


I wanted to add tool tips to a wxTreeListCtrl but had a little
trouble that I have since worked around.  I want the tool tips to be
based on the item I'm hovering over.


To do this, I added a handler for mouse motion and am using HitTest
to figure out which item I'm hovering over.


There's a problem with this, though: the header.  I needed a way to 
account for the height of the header but m_headerHeight is a private
member.


My first change was to make a protected GetHeaderHeight() method.
Then in my OnMouseMotion handler I can do this:


  wxPoint point (event.GetX(), event.GetY() + GetHeaderHeight());
  wxTreeItemId item = HitTest (point);




Second, wxWindow::SetToolTip() doesn't work correctly since it's 
really the main window that needs to handle the tool tip.  So my
second change was to override wxTreeListCtrl::SetToolTip() and 
have my function call m_main_win::SetToolTip().


Here's the whole function that I added to the end of treelistctrl.cpp:


void wxTreeListCtrl::SetToolTip (const wxString &tip)
{
  m_main_win->SetToolTip (tip);
}


And here are the changes I made to the protected section of treelistctrl.h: 


    int GetHeaderHeight() const { return m_headerHeight; }
    void SetToolTip (const wxString &tip);
