291217 - Dragging objects with png demo almost impossible

Status: RESOLVED INVALID

(Core :: Web Painting, defect)

Description

See url.
You should be able to drag the sun and the eagle, but this is not possible with
current trunk build.
Works with 2005-05-14 build, fails with 2005-04-15 build, so my guess is this is
a regression from fixing bug 289792.

Confirming
much easier with the older build

I think what we're doing with this demo now is quite correct, strictly speaking.
Shouldn't the script do preventDefault() to stop the brower's default drag
action kicking in?

Comment 3

[Martijn Wargers (dead)]

Ah, ok. Makes sense. I just noticed a change in behavior. That made my alarm
bells go off.

Comment 4

[Martijn Wargers (dead)]

On the other hand, it might be correct that the default drag action kicks in,
but when I release my mouse button, the objects follow my mouse movement, as if
I did not release my mouse button above the object. Isn't that a bug?
I still release my mouse button above the object, so the object should have
'received' the mouseup event, not?

I don't know. I suppose we could continue to fire mousemove and mousedown events
while also processing drag events ... it's really a question of what the DOM
standards and application developers expect. CCing jst and neil for an answer...

I'd expect dragover events instead of mouseover events.

Then this bug should remain invalid.
