Re: [sc-dev] Getting back to ViewRedirect from a View

Hi Jost,

  The workaround for me is to do everything in the GUIEvent.
But the subclassing problem is real and inescapable. I don't really see a way around it without a substantial redesign. (Seems like there would need to be a way to have a single class library that interfaces to both sets of graphics primitives.)

  BTW: could we add onClose to the EZ classes?

Hi Jost,

Actually, I may be able to handle this a little differently.
So, let's hold off for the moment.

ok, now I see the problem.

we could put this in SCView:

+SCView{
  genericName {
  var classKey;

  classKey=this.class.asString;
  classKey[0]=classKey[0].toLower;

 ^classKey.asSymbol

}
and then it could be overridden in those classes where the key is not 
like that (SC2DSlider is slider2d, e.g.).

that would make less clutter.

(did you need this as a class method?)
I think the idea with the dictionary is too awkward. People have to be able to subclass without too much hassle. I guess someone will have to write a little cross platform subclassing tutorial. We could use your 
technique and add it to the SCUserView subclassing tutorial I wrote.


any other suggestions?

Hi Jost and all,

To make CV work for both Swing and Cocoa, it has to work whether or
not the library is installed. So, I cannot
subclass directly, but I still have to attach an action to the actual 
view.  (Since the interfaces are identical this is not that big a
deal.)

The easiest way to do this would be to have a method for every view
(cocoa or swing) that provides its  ViewRedirect classname.
This could be something like:

+SCSlider {
  genericName { ^'slider' }
}

This seems plausible, but I don't know if there is enough need to
clutter up all the view classes.

Alternatively, I can just generate a Dictionary in StartUp (by
reading the schemes available to GUI and looking everything up)
and keep it inside CV.

Any thoughts, preferences or alternative approaches?

I wasn't quite sure what you were asking me, but: the only reason I 
used
ViewRedirect for EZSlider was that relativeOrigin is not
implemented yet
for swing containters. EZSlider is written for cross platform, it's 
just
that I have to redirect to the old version for swing at the moment. 
The
old version is EZSliderJ for swing, and the new one is EZSliderSC for 
Cocoa.  Once relativeOrigin is implemented for swing, there will
only be
EZSlider, namely the new one.

You were subclassing EZSlider, so you have to substitute that for
EZSliderSC temporarily (I really hope sciss gets this done before 3.3, it would really make things easier). If you want to be cross platform, 
duplicate your extra methods and subclass both EZSliderSC and
EZSliderJ.
In the actual code, you will the redirect class, EZSlider.

as for where to find other schemes, there is only on other one, an
that
is in the swingOSC library. If you install swingOSC, then you can
get it
under SwingGUI.

I hope that was what you wanted to know,

best

Hi Jost,
I am going to rewrite the CV connect code so that it is all a method 
of CV and looks up the appropriate connect action.
Where do I find the equivalents of CocoaGUI for other GUI schemes?
