The document-wide link update permission is decided when the document is
loaded. But media files that the users interactively inserts should be
automatically allowed.
Remember on the media object that the user picked the reference and
allow it on its own, the same way a presentation sound the user picks is
allowed. A reference that arrived with the document still needs the
document-wide permission.

Graphics Related Helper Code
Contains graphics related helper code. Lots of the draw and impress code is in this shared library.
-
xoutdevthis is where a lot of the work would happen to move to the canvas. (what does that mean?)
-
svdrawtransparent gradient stuff. [seriously? surely much more, too]
SdrObject
The shapes you can see in LibreOffice (like rectangle, etc.) are SdrObjects. They are declared as a hierarchy:
SdrObject <- SdrAttrObj <- E3dObject <- E3dCompoundObject <- E3dCubeObj
^ ^ ^ ^ ^ | | ^ ^
| | | | | | | | +--- E3dExtrudeObj
| | | | | | | +----- E3dLatheObj
| | | | | | +------- E3dPolygonObj
| | | | | +--------- E3dSphereObj
| | | | +--- E3dScene...
| | | |
| | | +--- SdrTextObj <- SdrObjCustomShape...
| | | ^ ^ ^ ^ ^
| | | | | | | +--- SdrEdgeObj...
| | | | | | +----- SdrMeasureObj...
| | | | | +------- SdrPathObj...
| | | | +--------- SdrRectObj...
| | | +----------- SdrTableObj...
| | +--- SdrObjGroup...
| + ---- SdrPageObj...
+------- SdrVirtObj...
The above is incomplete of course.
SdrModel / SdrView
Copied from svdview.hxx:
First of all the app creates a SdrModel.
Then it opens a Win and creates a SdrView.
ShowSdrPage() announces a page at SdrView.
It's possible to show SdrView in any Wins at once.
SdrView can show as many Wins as it wants at once. Pages are announced
or checked out with the help of ShowSdrPage()/HideSdrPage(). For every announced
page there is a SdrPageView instance in container aPages. If more than one page
is showed, you have to pay attention that the offset parameter of ShowSdrPage()
is conformed to the size of the page (to prevent overlapping of two pages).
SdrView itself is inherited from many objects in a chain of inheritance (all
that starts with SdrPaintView - that is itself inherited from few classes
too):
SdrPaintView <- SdrSnapView <- SdrMarkView <- SdrEditView <- SdrPolyEditView
^
+----------------------------------------------------------------+
|
SdrGlueEditView <- SdrObjEditView <- SdrExchangeView <- SdrDragView
^
+----------------------------------------------------------------+
|
SdrCreateView <- SdrView
From SdrView on, it is not flat, but a real hierarchy again.
Drawing Layer / SdrObject(s)

For SdrObjects, there are own DrawingLayer primitives in
svx/source/sdr/primitive2d
The ViewContact / ViewObject / ViewObjectContact are in svx/source/sdr/contact
Decomposes the SdrObjects, and does all sort of operations on them.
If the number of visualizable objects (e.g. SdrObjects) is X, and the number of
SdrViews is Y, then:
- there are
XViewContactinstances (1:1 relation with a visualizable object) - there are
YObjectContactinstances (1:1 relation with anSdrView) - there are
X*YViewObjectContactinstances (1:N relation to both visualizable objects andSdrViews)
