[news.eclipse.platform] Re: How to get default font in Table

[Ed Merks <merks@xxxxxxxxxx>]

Tom,

It's easy, though not self evident.  I suppose it's documented somewhere 
in that documentation I never read.  :-)

It also seems a little dangerous to use a global registry for a 
particular column viewer.  You'd certainly need to be careful to create 
a key that's unique to this particular column viewer wouldn't you?  
(Especially for code that might be reused a lot and have different fonts 
in different places.)  And then I'm not certain if this registry gets 
cleaned up when my viewer is deleted, so it might accumulate 
viewer-specific garbage.

I'll bet there isn't a single IFontLabelProvider implementation that 
doesn't need to keep track of the default font for what it's viewing, so 
I would have hoped for something more "built-in".  One problem I see in 
this regard is that while an IContentProvider has an inputChanged so it 
knows the viewer that's using it, the ILabelProvider has no such 
mechanism (that I know of).
