sheet-transformation [Generic Function]
(setf sheet-transformation) [Generic Function]
Arguments: transformation sheet
Summary: Returns a transformation that converts coordinates in the sheet sheet 's coordinate system into coordinates in its parent's coordinate system. Using setf on this accessor will modify the sheet's coordinate system, including moving its region in its parent's coordinate system. When the the transformation is changed, note-sheet-region-changed is called to notify the sheet of the change.
sheet-region [Generic Function]
(setf sheet-region) [Generic Function]
Summary: Returns a region object that represents the set of points to which the sheet sheet refers. The region is in the sheet's coordinate system. Using setf on this accessor modifies the sheet's region. When the region is changed, note-sheet-region-region is called to notify the sheet of the change.
Summary: Moves the sheet sheet to the new position ( x , y ). x and y are expressed in the coordinate system of sheet 's parent.
resize-sheet [Generic Function]
Summary: Resizes the sheet sheet to have a new width width and height height . width and height are real numbers.
move-and-resize-sheet [Generic Function]
Arguments: sheet x y width height
Summary: Moves the sheet sheet to the new position ( x , y .) and changes its size to the new width width and height height . x and y are expressed in the coordinate system of sheet 's parent. width and height are real numbers.
map-sheet-position-to-parent [Generic Function]
Summary: Applies the sheet sheet 's transformation to the point ( x , y ), returning the coordinates of that point in sheet 's parent's coordinate system.
map-sheet-position-to-child [Generic Function]
Summary: Inverts sheet 's transformation of the point ( x , y ) in sheet 's parent's coordinate system. It returns the coordinates of the point in sheet 's coordinate system.
map-sheet-rectangle*-to-parent [Generic Function]
Summary: Applies sheet 's transformation to the bounding rectangle specified by the corner points ( x1 , y1 ) and ( x2 , y2 ), returning the bounding rectangle of the transformed region as four values, min-x , min-y , max-x , and max-y . The arguments x1 , y1 , x2 , and y2 are canonicalized in the same way as for make-bounding-rectangle .
map-sheet-rectangle*-to-child [Generic Function]
Summary: Applies the inverse of the sheet sheet 's transformation to the bounding rectangle delimited by the corner points ( x1 , y1 ) and ( x2 , y2 ) (represented in sheet 's parent's coordinate system), returning the bounding rectangle of the transformed region as four values, min-x , min-y , max-x , and max-y . The arguments x1 , y1 , x2 , and y2 are canonicalized in the same way as for make-bounding-rectangle .
child-containing-position [Generic Function]
Summary: Returns the topmost enabled direct child of the sheet sheet whose region contains the position ( x , y ). The position is expressed in sheet 's coordinate system.
children-overlapping-region [Generic Function]
children-overlapping-rectangle* [Generic Function]
Summary: Returns the list of enabled direct children of the sheet sheet whose region overlaps the region region . children-overlapping-rectangle* is a special case of children-overlapping-region in which the region is a bounding rectangle whose corner points are ( x1 , y1 ) and ( x2 , y2 ). The region is expressed in sheet 's coordinate system. This function returns fresh objects that may be modified.
sheet-delta-transformation [Generic Function]
Summary: Returns a transformation that is the composition of all the sheet transformations between the sheets sheet and ancestor . If ancestor is nil , this returns the transformation to the root of the sheet hierarchy. If ancestor is not an ancestor of sheet, the sheet-is-not-ancestor error will be signaled.
The computation of the delta transformation is likely to be cached.
sheet-allocated-region [Generic Function]
Summary: Returns the visible region of the sheet child in the sheet sheet 's coordinate system. If child is occluded by any of its siblings, those siblings' regions are subtracted (using region-difference ) from child 's actual region.
