So You would be fine with e.g. the following:
- Take the outline of the selected objects
- Take the line width of the object, add a definable size
for selected
(e.g. 2 mm)
- Use a dashed linestyle for it (to have spaces where the
original
shape's linestyle is visible)
- Draw it as selection in a definable color (selection color
of the system)
Optional:
- draw it 50% transparent (evtl. without dashed)
- animate it
Maybe we should take the normal text selection case as a
analogon.
There, the selection is (depending on app) a x-or'ed or with
selection-color painted rectangle. We also have a blinking
cursor.
The analog for a draw application would be a rectangle/XOR
region for
each multi-selected shape.
XOR has it's own problems (gray background), so when using
selection
color, a text selection seems to be 'behind' the text. For
text
selections there is no problem, there are no chars which
completely
cover their selection area. This is different for shapes, so
maybe the
selection area needs to be a bit expanded.
This would allow to also visualize one of the multi-selected
objects as
'active' object (similar to the blinking cursor). This is
required for
being able to change multi-selection using only keyboard
(not possible
ATM, but required for accessibility, see issue #i44042#).
There must be
a possibility to 'travel' one object of the multi-selection.
I made a document with some examples. The selection color is
just for
experimenting, You may change it in the sytles dialog.
Attaching.
I hope for playing around with more ideas here. Be creative!
