[actionstep-core] ASsymbolImageRep enhancement

[thomas m. <tho...@gm...>]

Helo all,

I've been finding myself trying to use the size of a symbol representation
before its being drawn, like if I want to use setAlignment on it :

----
var rect:NSRect = new NSRect(30,100,200,200);
var img:NSImage = (new NSImage()).init();
var rep:ASSymbolImageRep = new ASSymbolImageRep("logo_sm");
img.addRepresentation(rep);

var iv:NSImageView = new NSImageView();
iv.initWithFrame(new NSRect(0,0,300,300));

iv.setImage(img);

iv.setImageAlignment(NSImageAlignment.NSImageAlignTopRight);

win.contentView().addSubview(iv);
----

since it seem the repSizeForClip method is only called when the rep is drawn
it was not working (the scaledImageFrameForRect of the NSImageCell class
would not get a size for the NSImage)

so I extended ASSymbolImageRep to have the constructor of the child class
look lihe this :

---
public function SMSymbolImageRep(symbolName : String, size : NSSize) {

        super(symbolName, size);

        var size_mc:MovieClip =
_root.createEmptyMovieClip("__SIZEMC__",_root.getNextHighestDepth());

        if(m_size == undefined) {
            m_size = repSizeForClip(size_mc);
        }

        size_mc.removeMovieClip();

}
---

it's working for me so I'm happy :) but I was wondering if woud not be a
useful addition to the ASSymbolImageRep class, and if not then why ?

Thanks in advance

thomas

What's the problem exactly? Do you have a size with null values, or a
size with zero values?

You could have done this:

m_size = NSSize.ZeroSize;

This would have saved you the trouble of creating and destroying a
dummy clip to set the size.

Hi,
sorry about that, my mistake. You *have* to use repSizeForClip.

[Scott H. <sc...@af...>]

It's an interesting idea, but there is a problem. You are relying on
_root to attach the symbol. The symbols may not necessarily be there
(they could be under a loadMovie'd clip).

Ray is correct in suggesting repSizeForClip().

Re: [actionstep-core] ASsymbolImageRep enhancement

[thomas m. <tho...@gm...>]

hi

I was using repSizeForClip().

and you're right about _root, I figured it out later.

It leaves me with my question :

how do I get the size of the symbol before the draw cycle ?

because for instance I think If I want to use NSImage.setImageAlignment()
and that I don't set a size for the image (and I want the image to the size
of the symbol) it won't work (since the size() yields widht=undefined and
height=undefined)

I resort to calling repSizeForClip passing the view mcBounds as the base
clip like :

var size_mc:MovieClip = win.rootView
().mcBounds().createEmptyMovieClip("__SIZE_MC__",_root.getNextHighestDepth());
var symbolSize = rep.repSizeForClip(size_mc);
size_mc.removeMovieClip();

I also thought about passing the current view to the rep ...

Re: [actionstep-core] ASsymbolImageRep enhancement

[Ray C. <rc...@gm...>]

It shouldn't matter which clip you pass to repSizeForClip, since the
size is not affected by the clip it is attached to. It's a different
story for co-ordinates, though.
