gEDA-bug: [Bug 708388] Re: Select all and deselect actions are too slow

[Peter Clifton <pcjc2@xxxxxxxxx>]

See o_basic.c:

void o_redraw_rects (GSCHEM_TOPLEVEL *w_current,
                     GdkRectangle *rectangles, int n_rectangles)

  obj_list = s_page_objects_in_regions (toplevel, toplevel->page_current,
                                        world_rects, n_rectangles);

The implementation of that could be a spatial lookup if we needed in the
future. I have a branch which uses r_tree code from PCB to achieve that,
but it is not 100% tested.

Title:
  Select all and deselect actions are too slow

Status in GPL Electronic Design Automation tools:
  New

Bug description:
  Select/deselect actions in gschem take up to 1 second on a moderately
  large schematic (900 lines in saved file).

  This is an annoyance and can hamper usability - the user can start
  repeating keystrokes or mouse clicks due to lack of feedback.
