drag&drop in gtk apps not working anymore

Chacabaou

Hello,

this problem showed up quite a long time before (about some months) and unfortunately I didn't notice it soon enough, because I rarely restart firefox, my main gtk app. Therefore, I cannot tell, which upgrade introduced the problem. Actually, this fact IS my problem.

As mentioned, I can't do drag&drop in gtk applications anymore, e.g. can't move bookmarks and tabs in firefox, or images in gqview. At first, I suspected some messed configuration or profile, created a new user and noticed that the problem is definitely system-wide.

To be a little more exact on the issue: when I try to drag some item, the cursor changes as expected, but I'm not able to drop it anywhere. No matter, where I release the button, the "flying document symbol" goes back to the item's origin.

No idea, what information could be helpful... here are at least my versions and use flags of any packages matching to "gtk".

Gtk+ (in fact all Gnome packages) do not support -O3 in CFLAGS, and gtk+ is known to break with it (including drag-and-drop). Post the output from emerge --info, please.

Hello!

You just don't know how thankful I'd have been, if that would be the solution.

But as you can see...no -O3:

Well, some people say it shouldn't matter, but there are others that say that gtk+ is also broken when built with gcc 4.1. If you want to rebuild it with gcc 3.x, then do the following (as root):

Thanks for you advice, but unfortunately, it didn't help.
I did exactly the steps you told me, ran gqview and tried to drag&drop an image into the 'find duplicates' window (->an action, which I expected to work, but I can't tell for sure).

Maybe I missed any step? Is there a way to check, if my gtk apps do really link to gtk libraries compiled with gcc-3.4, now?

You'd probably have to call revdep-rebuild with the --library option for each gtk+ library. If you want to test just the one program, re-emerge just that one and try your test again. Does drag & drop work with gaim conversation windows?

You mean, recompiling gtk+ with another gcc version wouldn't have any effect until I recompile the apps linking to it?
I'd really wonder, if this is true, but I'll try (recompiling gqview).

I can't test gaim, since I don't use it.

Well, that didn't help, either. :/

Well, I am at a loss, then. I guess the next step would be to file a bug report (after making sure there isn't already one, of course). Hope you figure it out.

Hmm... disappointing.

Well, thanks for your help anyways!

Fixed here. Recompiling Thunar did the trick (from where I was attempting to drag files to Audacious). :wink:

sorry to dig this bad boy back up.. but I'm experiencing the exact same thing with gtk/gnome apps. Firefox.. unable to move tabs, claws-mail unable to drag messages, pidgin unable to move contacts. I've already recompiled claws-mail several times. Working on gtk+ now.

I have -O2 in make and I'm using gcc-4.3.4
