KoViewChild has basically three geometries to keep in sync.
|
|
- The KoDocumentChild tqgeometry (i.e. the embedded object's tqgeometry, unzoomed)
|
|
- Its own tqgeometry (used for hit-test etc.)
|
|
- The KoFrame tqgeometry (the graphical widget for moving the object when active)
|
|
|
|
So we need to subtract the scrollview's offset for the frame tqgeometry, since it's a widget.
|
|
|
|
The rules are
|
|
(R1) frameGeometry = viewGeometry(childGeometry) "+" m_frame->{left|right|top|bottom}Border() - scrollview offset,
|
|
(R2) frameGeometry = myGeometry "+" active_frame_border - scrollview offset.
|
|
|
|
So: (R3, unused) myGeometry = viewGeometry(childGeometry) "+" m_frame->{left|right|top|bottom}Border() "-" active_frame_border
|
|
|
|
Notes: active_frame_border is m_frame->border() (0 when inactive, 5 when active).
|
|
{left|right|top|bottom}Border are the borders used in kspread (0 when inactive, big when active).
|
|
"+" border means we add a border, so it's a subtraction on x, y and an addition on width, height.
|
|
|
|
viewGeometry() applies the zoom as well as any other translation the app might want to do
