This class combines containers' control initialization into a single call.
This class and its members cannot be used in applications that execute in the Windows Runtime.
template <class T> class ATL_NO_VTABLE IQuickActivateImpl : public IQuickActivate
Your class, derived from
|IQuickActivateImpl::GetContentExtent||Retrieves the current display size for a running control.|
|IQuickActivateImpl::QuickActivate||Performs quick initialization of controls being loaded.|
|IQuickActivateImpl::SetContentExtent||Informs the control of how much display space the container has assigned to it.|
The IQuickActivate interface helps containers avoid delays when loading controls by combining initialization in a single call. The
QuickActivate method allows the container to pass a pointer to a QACONTAINER structure that holds pointers to all the interfaces the control needs. On return, the control passes back a pointer to a QACONTROL structure that holds pointers to its own interfaces, which are used by the container. Class
IQuickActivateImpl provides a default implementation of IQuickActivate and implements IUnknown by sending information to the dump device in debug builds.
Retrieves the current display size for a running control.
The size is for a full rendering of the control and is specified in HIMETRIC units.
See IQuickActivate::GetContentExtent in the Windows SDK.
Performs quick initialization of controls being loaded.
STDMETHOD(QuickActivate)( QACONTAINER* pQACont, QACONTROL* pQACtrl);
The structure contains pointers to interfaces needed by the control and the values of some ambient properties. Upon return, the control passes a pointer to a QACONTROL structure that contains pointers to its own interfaces that the container requires, and additional status information.
See IQuickActivate::QuickActivate in the Windows SDK.
Informs the control of how much display space the container has assigned to it.
