The EnumObjects function enumerates the pens or brushes available for the specified device context. This function calls the application-defined callback function once for each available object, supplying data describing that object. EnumObjects continues calling the callback function until the callback function returns zero or until all of the objects have been enumerated.
int EnumObjects(
HDC hdc, |
// handle to device context |
int nObjectType, |
// object-type identifier |
GOBJENUMPROC lpObjectFunc, |
// pointer to callback function |
LPARAM lParam |
// pointer to application-supplied data |
); |
The return value specifies the last value returned by the callback function. Its meaning is user-defined. The return value is -1 if there are too many objects to enumerate. In this case, the callback function is not called.
