Článek

Sets the rectangular coordinates of the viewport in which the view is to be activated or resets the coordinates of the viewport in which a view is currently activated.

Syntax

HRESULT SetRect(
  [in] LPRECT prcView
);

Parameters

[in] prcView

A pointer to a RECT structure containing the coordinates of the viewport.

Return value

This method returns S_OK on success. Other possible return values include the following.

Return code	Description
E_FAIL	The operation failed.

Remarks

For a single document interface (SDI) application, the viewport is the client area of the frame window minus the space allocated for toolbars, status bar, and such. For a multiple document interface (MDI) window, the viewport is the client area of the MDI document window minus any other frame-level user-interface elements.

Notes to Callers

Calling IOleDocumentView::SetRect or IOleDocumentView::SetRectComplex is part of the normal activation sequence for document objects, usually following a call to IOleDocumentView::UIActivate and preceding a call to IOleDocumentView::Show.

Whenever the window used to display a document object is resized, the container should call IOleDocumentView::SetRect (or IOleDocumentView::SetRectComplex) to tell the document view object to resize itself to the new window dimensions.

Notes to Implementers

The coordinates of the viewport are within the coordinates of the view window, which is obtained through IOleWindow::GetWindow. The view must resize itself to fit the new coordinates passed in prcView.

This method is defined with the [input_sync] attribute, which means that the view object cannot yield or make another, non input_sync RPC call while executing this method.

A document view must implement this method completely; E_NOTIMPL is not an acceptable return value.
