Hi Rudolf, I all the data as packed binary in my own format … no SQL used. The app does everything with internal data structures, not SQL. ---

Jean-Yves, The app I was working on was originally done long ago - it used bitmaps, which was fine until recently when I was asked to add something. Selecting/dragging simple objects (ovals, rectangles) is easy, because a “contains” method is trivial. What wasn’t trivial in bitmaps was finding a way to select and drag/reshape an arbitrary open curve, in a complex drawing with many overlapping objects - there is no function to determine if you have clicked within say 3 pixels of an individual curve. However there is a way with vector graphics - the graphicsPath objects have a “contains” function. So, as shown in the example: (1) divide a complex curve into smaller simple arcs and (2) use the control points of these arcs to define small triangles containing each arc. Regards to all.
