GAUGE_PROGRESS_REPORTER(wxWindow *aParent, int aNumPhases)
This implements all the tricky bits for thread safety, but the GUI is left to derived classes.
wxAppProgressIndicator m_appProgressIndicator
WX_PROGRESS_REPORTER(wxWindow *aParent, const wxString &aTitle, int aNumPhases, bool aCanAbort=true, bool aReserveSpaceForMessage=true)
The PROGRESS_REPORTER will stay on top of aParent.
