C++ APPLICATION PROGRAMMING INTERFACE
1. Your first step will be to include the header file for your command or tool and
update the makefile to reflect this addition.
2. Next create an instance of your command or tool.
// Create an instance of your command
MyCommandClass* myCommand = new MyCommandClass();
// Create an instance of your tool
MyToolClass* myTool = new MyToolClass();
3. Now place your command or tool onto your application’s toolbar.
// Place the command onto the toolbar
AoToolbarAddCommand(ipToolbarControl, myCommand, esriCommandStyleIconOnly);
// Place the tool onto the toolbar
AoToolbarAddTool(ipToolbarControl, myTool, esriCommandStyleIconOnly);
Your options for the third parameter to AoToolbarAddCommand and
AoToolbarAddTool are the same as they are for adding built-in commands and
tools to the toolbar: esriCommandStyleIconOnly, esriCommandStyleTextOnly, and
esriCommandStyleIconAndText.
4. Compile your application. Your command or tool will be on the toolbar, ready
for you to use it.
