[OpenLayers-Users] SelectFeature hover control interfering with click-and-drag

[Robert Sanson]

Hi Roald
 
It was uncommented because I copied the code from another example and those lines were already commented out. I had since tried uncommenting those, and it worked! Sorry I didn't let the list know that I had solved it. Anyway, thanks for the response.
 
I am still using v2.6. Haven't tried v2.7rc1 yet.
 
Kind regards,
 
Robert Sanson

Hi Robert,

It seems you are/were very close to the solution of you problem: to
allow for the map to be dragged when your mouse pointer is over a
selectable feature, you need to override the stopDown and stopUp
attributes of the handler, just as you have in your code below (but then
uncommented!).

Could you explain why you have these lines commented out? Have you tried
uncommenting them? What version of OL are you using? 2.7-rc1, 2.6 or an
older version?

Today crschidt explained to me that in 2.7 the SelectFeature control
behaves a bit differently internally and in order for the fix work,
you'd need to rewrite the code. See [1]

But this might not apply to you and you might have other reasons why it
won't work for you.

Cheers, Roald
