BUILDING APPLICATIONS WITH C++ AND CONTROL WIDGETS
MwCtlAppMainLoop(app_context);
7. Before you shut down the application, you need to clean up the global
ArcObjects. Do this by setting the pointer for each control to 0.
void CloseAppCallback(Widget w, XtPointer client_data,
XtPointer call_data)
{
g_ipToolbarControl = 0;
g_ipMapControl = 0;
g_ipTOCControl = 0;
g_ipPageLayoutControl = 0;
// Uninitialize the engine
8. Compile the application by typing “make –f Makefile.SolarisMotif ” at the
command line.
9. Run the application by typing either “make run –f Makefile.SolarisMotif ” or
“./MapViewer” at the command line. Notice how the controls have been
placed in the application window. At this point the controls are all empty
because no commands or data have been added. Try resizing the main form,
and see that the TOCControl maintains its width, the ToolbarControl its
height, and the MapControl its dimensions, but the other dimensions and
controls resize themselves.
