BUILDING APPLICATIONS WITH C++ AND CONTROL WIDGETS
8. Update the makefile. Include PageLayoutControlEvents.cpp as a source, add
the header for the events to the MapViewer.o dependencies list, and add a
dependencies list for PageLayoutControlEvents.o.
9. Compile and run the application. The map document is now loaded into the
PageLayoutControl; and the TOCControl lists the data layers in the
MapDocument. By default, the focus map of the map document is loaded into
the MapControl.
Setting the Buddy Control for the TOCControl and ToolbarControl
For the purpose of this application, the TOCControl and ToolbarControl will
work in conjunction with the PageLayoutControl rather than the MapControl. To
do this the PageLayoutControl must be set as the buddy control. The
TOCControl uses the buddy’s ActiveView to populate itself with maps, layers,
and symbols, while any command, tool, or menu items present on the
ToolbarControl will interact with the buddy control’s display.
1. The buddy control is set after the widgets are created and their interface
pointers have been assigned, so you will set each one after FormSetup().
FormSetup(argc, argv, &app_context);
// Buddy the toolbar and TOC with the PageLayoutControl
g_ipToolbarControl->SetBuddyControl(g_ipPageLayoutControl);
g_ipTOCControl->SetBuddyControl(g_ipPageLayoutControl);

2. Remake the application and run it again. Notice that now the TOCControl
displays a layer icon as well as the data for the current document. Use the
TOCControl to toggle layer visibility by checking and unchecking the boxes.
At this point the ToolbarControl is empty because no commands have been
added to it.
