When you want to drag something from one app to another, you usually don't want the app you're dragging from to come to the front as soon as you start dragging (you don't NEED anything else visible . Windows Explorer fixes this by waiting until mouseup to switch focus when you click on some draggable things (such as files). MS didn't do it completely correctly, however: mousedown on the icon in the "address" bar still brings that window to the front. It would be really cool if mozilla did this "right".

NS 4.x does this "right", as far as I can tell. Good point.

yup, and then the drag still fails. changing severity to normal, assigning to saari as p3 for m18

As far as I can tell, this doesn't work correctly with IE 5 for MacOS. Not sure if I'll be able to fix this... switching focus to mouseup, especially conditionally, is a fairly scary change. I'll think about it, and give it a try though.

I haven't looked into the Windows code on this yet, but this sounds like it could be resolved on Windows by handling the WM_MOUSEACTIVATE message and returning WM_NOACTIVATE.

Not that easy, as the event sequence we care about really happens in XP code, and is fairly delicate.

As drag and drop comes back into the product more, this may be important. Would be nice to fix for Mozilla 1.0

I think bug 51323 is a duplicate of this bug, or is dependent on this bug, or blocks this bug, or something.

I'd change that bug to be only the second part, and let this bug handle the first part.

This is not only a problem when interacting with other programs, but within mozilla's windows: When dragging a link from the browser to the bookmarks window, mozilla browser takes focus when clicking to the link. I believe drag+drop shouldn't change window focus at all. This is the usual and most practical thing to do.

bryner, switching focus to mouseup is something we should explore for the next round of changes...

That would be this code, right? http://lxr.mozilla.org/seamonkey/source/content/events/src/nsEventStateManager.cpp#1741 But we'd only want to not bring the window to the front until mouseup. We still need to focus text boxes, activate links, etc. on mousedown.

Links currently activate on mouseUP... This lets us grab them and drag them off the window without activating them. Try it :)

Not for me. When I mouse down on a link, it gets a focus rectangle and changes to color (if defined). The link isn't followed until mouseup, yes.

D'oh! I'm an idiot. Sorry about that.

Does this bug include dragging an inactive tab in FF to a new position on the tab bar (which incorrectly activates the dragged tab instead of just moving it)?

No, that's bug 296970.
