Public Member Functions

 OpZoomFitSelectedDescriptor ()
 Constructs an OpDescriptor for the "Zoom to selected objects" button.

Protected Member Functions

virtual Spread * GetSpread (DocView *pDocView) const
 Provides the spread that OpZoomDescriptor::HandleButtonMsg will zoom in on.
virtual DocRect GetRect (Spread *pSpread)
 Assuming that some objects are selected, this calculates the bounding rectangle of the selected objects, including blobs.
virtual void AdjustRect (DocRect *pRect) const
 Inflates the given rectangle by the same amount as the selector tool when it draws bounds blobs around the selection. This ensures that after a "Fit to Selected" zoom the bounds blobs of the zoomed object will be visible.

void OpZoomFitSelectedDescriptor::AdjustRect (  DocRect *  pRect  )  const [protected, virtual]
 

Inflates the given rectangle by the same amount as the selector tool when it draws bounds blobs around the selection. This ensures that after a "Fit to Selected" zoom the bounds blobs of the zoomed object will be visible.

Parameters:
pRect pointer to a DocRect to adjust [INPUTS]
The adjusted DocRect. [OUTPUTS]
Returns:
-

DocRect OpZoomFitSelectedDescriptor::GetRect (  Spread *  pSpread  )  [protected, virtual]
 

Assuming that some objects are selected, this calculates the bounding rectangle of the selected objects, including blobs.

Author:

Parameters:
pSpread pointer to the spread containing the selection [INPUTS]
- [OUTPUTS]
Returns:
The bounding rectangle of the selected objects.

Errors: ERROR2/3 failure if there isn't any selected objects - if this happens then something is screwy, as SelRange immediately before reported that there are selected objects, or this function wouldn't have been called.
