Code compatibility

Hi,

Playing with custom osnaps, I discover some changes in the Glyph class between 2007 and 2010 versions.
With 2007, a class which inherits Glyph have to implement ViewportDraw(), with 2010 SubViewportDraw().

2007
{code}public override void ViewportDraw(ViewportDraw vd){code}

2010
{code}protected override void SubViewportDraw(ViewportDraw vd){code}

I solved the problem making two versions, but is there a way to have a single version in which, according to the current AutoCAD version, one or the other method is called (may be using a delegate) ?

In 2010, I don't see a SubViewportDraw(), but do see a SubWorldDraw().

Hi Tony,

> In 2010, I don't see a SubViewportDraw(), but do see a SubWorldDraw().

In ObjectARX 2010 docs for managed classes (arxmgd.chm), I didn't find neither SubViewportDraw() nor SubWorldDraw(). I only found the 'old' ViewportDraw().

Seems there're both subViewportDraw() and subWorldDraw() in AcGiDrawable methods (ARX) and a viewportDraw too...

It's Visual Studio intellisense which purpose to implement the abstrct class using:
protected override void SubViewportDraw(ViewportDraw vd)

And it works fine for 2010... Edited by: _gile on Feb 2, 2010 8:03 AM

I now see that SubViewportDraw() is an abstract
member of the base class (Drawable), which explains it.
