Migrating ArcGIS Motif Controls from 9.0 to 9.1

At 9.1 there have been a few changes to the ArcGIS Motif controls and how they are used. While existing applications will still run, if they need to be recompiled the following steps will need to be taken.

HRESULT MwCtlGetInterface(Widget w, IUnknown** ppUnk) replaces I<ControlName>Control* Ao<ControlName>ControlGetInterface(Widget w)

[Motif C++]


                  // 9.0 code
IMapControl3Ptr ipMapControl = AoMapControlGetInterface(mapWidget); 
  // mapWidget is a widget defined earlier// 9.1 code
IMapControl3Ptr ipMapControl = MwCtlGetInterface(mapWidget, (IUnknown **)
  &g_ipMapControl); // mapWidget is a widget defined earlier

aoctl library replaces aomotifctl library

Makefile at 9.0: -larcsdk -lmotifctl -laomotifctl

Makefile at 9.1: -larcsdk -lmotifctl -laoctl

Ao/AoMotifControls.h replaces the individual include for each control (Ao/<ControlName>.h)

[Motif C++]


                  // at 9.0
          #include <Ao/Map.h>
#include <Ao/Toolbar.h>
#include <Ao/TOC.h>

// at 9.1#include <Ao/AoMotifControls.h>

Tool, Command, and Event classes are no longer Motif-specific. esrisystemutility and control-specific tlh's are replaced by including Ao/AoControls.h, and Motif headers can be removed.
