The description for a visual class follows the same rules as for a nonvisual class, but it must inherit from the UserObject system class:
PBXEXPORT LPCTSTR PBXCALL PBX_GetDescription()
{
static const TCHAR desc[] = {
"class myvisualext from userobject\n"
"subroutine func_1(int arg1, int arg2)\n"
"subroutine func_2(string arga)\n"
"end class\n"
};
return desc; }
There are no events in the preceding example, but a typical visual extension makes use of events such as mouse clicks. There are two ways to declare and handle events. See “Event processing in visual extensions”.
