.. currentmodule:: globalmapper
.. py:function:: SelectProjectionEx (GM_Projection_t aInitProj, POINT aDlgPos, GM_SelectProjFlags_t32 aFlags, int aReserved) -> GM_Error_t32, GM_Projection_t

    Displays the projection selection dialog to allow the user to select a projection. If *aInitProj* is provided, the
    projection dialog is initialized to that projection. The caller can also optionally provide an initial location for
    the projection dialog on the screen as well as flags controlling the selection of the projection.

    :param GM_Projection_t aInitProj: initial projection to use (None for default)
    :param POINT aDlgPos: position of top left corner (in screen coordinates) for projection dialog (None for default)
    :param GM_SelectProjFlags_t32 aFlags: additional flags for projection selection
    :param int aReserved: Reserved for future use; must be 0.
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: Projection selected by user
    :rtype: GM_Projection_t
