Description

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.

Remarks

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.
