Determines if there is available space for tools to be installed around the
object's window frame while the object is active in place.
| LPCBORDERWIDTHS pborderwidths
|//Points to a BORDERWIDTHS structure
[in] Points to a BORDERWIDTHS
structure containing the requested widths (in pixels) needed on each side of
the window for the tools.
The requested space could be allocated to the object.
The object cannot install toolbars in this window object because the
implementation does not support toolbars, or there is insufficient space to install the
One or more invalid arguments (for example, an invalid pointer or parameter).
An unexpected error occurred.
Notes to Callers
The active in-place object calls IOleInPlaceUIWindow::RequestBorderSpace
to ask if tools can be installed inside the window frame. These tools would be
allocated between the rectangle returned by IOleInPlaceUIWindow::GetBorder
and the BORDERWIDTHS
structure specified in the argument to this call.
The space for the tools is not actually allocated to the object until it calls IOleInPlaceUIWindow::SetBorderSpace
, allowing the object to negotiate for space (such as while dragging toolbars
around), but deferring the moving of tools until the action is completed.
The object can install these tools by passing the width in pixels that is to
be used on each side. For example, if the object required 10 pixels on the top,
0 pixels on the bottom, and 5 pixels on the left and right sides, it would pass
the following BORDERWIDTHS
structure to IOleInPlaceUIWindow::RequestBorderSpace
lpbw->top = 10
lpbw->bottom = 0
lpbw->lLeft = 5
lpbw->right = 5
While executing IOleInPlaceUIWindow::RequestBorderSpace
, do not make calls to the Windows PeekMessage
functions, or a dialog box. Doing so may cause the system to deadlock. There
are further restrictions on which OLE interface methods and functions can be
called from within RequestBorderSpace
Notes to Implementors
If the amount of space an active object uses for its toolbars is irrelevant to
the container, it can simply return NOERROR as shown in the following IOleInPlaceUIWindow::RequestBorderSpace
example. Containers should not unduly restrict the display of tools by an
active in-place object.
