/**
    @class wxCollapsiblePane
    @wxheader{collpane.h}

    A collapsible pane is a container with an embedded button-like control which
    can be
    used by the user to collapse or expand the pane's contents.

    Once constructed you should use the wxCollapsiblePane::GetPane
    function to access the pane and add your controls inside it (i.e. use the
    wxCollapsiblePane::GetPane's returned pointer as parent for the
    controls which must go in the pane, NOT the wxCollapsiblePane itself!).

    Note that because of its nature of control which can dynamically (and
    drastically)
    change its size at run-time under user-input, when putting wxCollapsiblePane
    inside
    a wxSizer you should be careful to add it with a proportion value
    of zero; this is because otherwise all other windows with non-null proportion
    values
    would automatically get resized each time the user expands or collapse the pane
    window
    resulting usually in a weird, flickering effect.

    Usage sample:

    @code
    wxCollapsiblePane *collpane = new wxCollapsiblePane(this, wxID_ANY,
    wxT("Details:"));

        // add the pane with a zero proportion value to the 'sz' sizer which
    contains it
        sz-Add(collpane, 0, wxGROW|wxALL, 5);

        // now add a test label in the collapsible pane using a sizer to layout it:
        wxWindow *win = collpane-GetPane();
        wxSizer *paneSz = new wxBoxSizer(wxVERTICAL);
        paneSz-Add(new wxStaticText(win, wxID_ANY, wxT("test!")), 1, wxGROW|wxALL,
    2);
        win-SetSizer(paneSz);
        paneSz-SetSizeHints(win);
    @endcode

    It is only available if @c wxUSE_COLLPANE is set to 1 (the default).

    @beginStyleTable
    @style{wxCP_DEFAULT_STYLE}:
           The default style: 0.
