has this been done?
is there a plugin for sale?
I have written some code to implement your own "pointer" mode
(selecting an object reveals handles, grabbing the handles let you
move the object around, resize it), along with basic functions for
drawing lines and circles. If you still need this, please contact me
privately for information.
Once upon a time I started down the road of making a universal
drawing tool palette, but in the real world I've found that each
app requires something a little different, so I'm not sure it can
usefully be done as a one-size-fits-all.
And then there's the question of how to handle the other properties
(line size, fill/back color/pattern, etc.) -- in the same palette a
la FileMaker, or in a separate palette that eats up a ton of screen
space a la Flash. Decisions, decisions....
Fortunately it's not too difficult to slap one together from
scratch when you need it; mildly tedious if you do it more than
once, but if you make enough of them it becomes second nature after
a while.
You can have both the FileMaker and Flash options at hand, to choose
from if you take an object-oriented + MVC approach to the problem.
You then subdivise a big palette into smaller chunks with limited
functionalities and you write some generic code for assembling the
chunks within a toolbar or a palette format. Surprisingly easy to do
with revolution once you resist the temptation to write your code at
the smallest object level and to rather write everything at group
level, with a dispatching function at group level to identify which
object has been pressed. With such an approach, it becomes a breeze
to to reuse the same widgets in various applications.
