gEDA-bug: [Bug 700841] Re: gschem: during selection invisible attributes extend component bounding box

[Peter Clifton <pcjc2@xxxxxxxxx>]

Further nit:

Please don't do this:

+  (void) toplevel;

The compiler won't complain if that is part of the public API, even if
the toplevel argument isn't used. Let me know if you have a compiler
which does otherwise.

+gboolean
+o_is_visible (TOPLEVEL *toplevel, OBJECT *object)
+{
+  g_return_val_if_fail (object != NULL, FALSE);
+  (void) toplevel;
+  return object->visibility == VISIBLE;
+}
+

Title:
  gschem: during selection invisible attributes extend component bounding box 

Status in GPL Electronic Design Automation tools:
  In Progress

Bug description:
  Intermittently gschem gets into a state when promotable (visible) attributes within a component extend component's bounding box used for selection calculations.
In such cases component might not be selected even if selection rectangle encloses component's graphics and pins.
It is also possible to select the component by clicking on an empy space far away from it - because in the symbol file a visible attribute is located at that offset.

It is expected that components can be always selected by drawing a selection rectangle that encloses all graphical elements and pins.

When the bug occurs, toggling "show/hide invisible text" restores correct behavior.
