IOleInPlaceSiteWindowless::AdjustRect
Adjusts a
specified rectangle if it is entirely or partially covered by overlapping,
opaque objects.
HRESULT AdjustRect(
LPRECT prc |
//Rectangle
to adjust |
); |
|
Parameters
prc
[in,out]
Rectangle to adjust.
Return Values
S_OK
The rectangle
was adjusted successfully. Note S_OK means that the rectangle was not
completely covered.
S_FALSE
The rectangle
was adjusted successfully. Note S_FALSE means that the rectangle was completely
covered. Its width and height are now NULL.
Remarks
The main use
of this method is to adjust the size of the caret. An object willing to create
a caret should submit the caret rectangle to its site object by calling this
method and using the adjusted rectangle returned from it for the caret. If the caret
is entirely hidden, this method will return S_FALSE and the caret should not be
shown at all in this case.
In a
situation where objects are overlapping this method should return the largest
rectangle that is fully visible.
This method
can also be used to figure whether a point or a rectangular area is visible or
hidden by overlapping objects.
