template <class T, REGENTRY * pdsRegArray, DWORD dwToolboxSupport, int iDesignerNameID = 0>
class CComDesignerToolbox : public CComDesignerBase<T, pdsRegArray>
Parameters
T
Your class, derived from CComDesignerBase.
pdsRegArray
Pointer to REGENTRY array set up by registration macros.
dwToolboxSupport
DWORD value indicating required toolbox support. The value is one or more of the following: ISUPPORT_NONE, ISUPPORT_DRAGDROP, ISUPPORT_CLICKDRAG, ISUPPORT_BOTH.
iDesignerNameID
Resource ID of the toolbox name string. This ID must be a valid string resource in the resource (.rc) file.
CComDesignerToolboxSupport provides default toolbox support for the design-time object, specified through a set of registration macros. You can set up support for intrinsic toolbox items or ActiveX controls that can be dragged onto the designer surface. (Note that the samples, however, do not host ActiveX controls.) To use this class, the designer must also derive from CComControl.
