Re: [gef-dev] Auto-expose and marquee tools

Doesn't the auto-expose stuff expose
editparts?  For the marquee tool, you would just want to expose the
point where the lasso is currently dragged, right?  If so, maybe there's
not much intersection between the two.

Do you need marquee expose to work in
nested scrollable containers, or just the viewer itself?

Subject	[gef-dev] Auto-expose and marquee tools

Hi!

I'd like to add and contribute support for auto-expose on the marquee
tools. Currently I see three options.

1. Move auto-expose implementation from TargetingTool into AbstractTool.
2. Move auto-expose implementation from TargetingTool into a new
abstract class AutoexposeTool and inherit from this class.
3. Reimplement auto-expose in the marquee tools.
 
I don't want to go the 3rd way. What's the best way to go? The 2nd is
the more cleaner way. 

BTW, I also attached a new patch to
https://bugs.eclipse.org/bugs/show_bug.cgi?id=44288

This adds an additional contructor which allows clients to create a
ViewportAutoexposeHelper that continues scrolling if the pointer is
moved outside the viewport.

Cu, Gunnar
