Bug 74439 – gaim conversation scroll bar moves to the top instead to the end when a new message is received or sent

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Perry Lu 2004-12-14 19:29:34 UTC]

I've been having this bug for quite a while now, every time when I have a conversation, the scroll bar would stop scroll to the end, instead, it scrolls backward to a fixed location whenever a message is received or sent. I've did some debugging myself, it boils down to the following line: 
gtk_text_view_scroll_to_mark(GTK_TEXT_VIEW(imhtml), imhtml->scrollpoint, 0, TRUE, 1.0, 0.0);
in function: void gtk_imhtml_scroll_to_end(GtkIMHtml *imhtml)
in class: GtkIMHtml (gtkimhtml.c)
I didn't check whether it's the bug with the GTK+ API function, or the problem with the variable values.

I'm using gaim-1.1.0, gtk+-2.4.14.

Reproducible: Always
Steps to Reproduce:
1.start a conversation on gaim with any protocal
2.continue the conversation until the scroll bar handle is about half the size of the scroll bar itself
3.continue even further after that(this bug would occur)

Actual Results:  
the conversation window no longer moves to the end after every message, it jumps
backward to a fixed location.

Expected Results:  
the conversation window should always moves to the end.

Please paste results of `emerge info`.  Also are you using the history plugin?  I'm unable to duplicate this behavior.

[Comment 2 Don Seiler (RETIRED) 2005-01-14 11:40:05 UTC]

Please let me know all other plugins you have loaded.

[Comment 4 Perry Lu 2005-01-14 12:38:02 UTC]

I have Auto-Reconnect, Extended Preferences, System Tray Icon loaded. I'm not using the history plugin.

[Comment 5 Perry Lu 2005-01-14 12:44:56 UTC]

there have been similar reports on the gaim sourceforge bugs page:

[Comment 6 Don Seiler (RETIRED) 2005-01-14 12:54:14 UTC]

Can you try without the Extended Preferences?

I'm not sure if your bug here is a duplicate of either of those upstream bugs.

[Comment 7 Perry Lu 2005-01-14 13:32:24 UTC]

The bug persists. I installed Extended Preference just recently, in a desperate attempt trying to fix the problem.

[Comment 8 Drew Winstel 2005-02-15 19:12:13 UTC]

Seems to still be present, Gaim 1.1.2.  No combination of plugins has any effect.

[Comment 9 Robert Gloven 2005-03-03 18:21:17 UTC]

Myself and a friend of mine have this problem as well.  It's prevalent on gaim 1.1.4, no plugins installed.  Is anyone looking at this?

[Comment 10 Drew Winstel 2005-03-22 19:43:31 UTC]

I don't know, but it hasn't been fixed in 1.2.0.

[Comment 11 Drew Winstel 2005-03-22 20:23:05 UTC]

Created attachment 54200 [details, diff]
Patch to gtk_text_view_scroll_to_mark() as called in void gtk_imhtml_scroll_to_end(GtkIMHtml *imhtml)

http://developer.gimp.org/api/2.0/gtk/GtkTextView.html#gtk-text-view-scroll-to-mark


The y-value (final argument of gtk_text_view_scroll_to_mark()) should be set to
1.0, which equals bottom. 

Note that this applies to gaim-1.2.0/src/gtkimhtml.c.

Effect on gaim:
It now scrolls back to the point where the conversation previously was (so if
you have the scrollbar 10 lines from the bottom, it keeps the bottom of the
window such that the last line you saw previously is still at the bottom of the
window.

This patch has already been rejected.

Care to rebuild gtk and gaim with some saner CFLAGS and try again?

[Comment 13 Perry Lu 2005-03-23 17:27:32 UTC]

the problem was solved after I removed "-mftpmath=sse,387" from CFLAGS and rebuilt gtk+.

seems that's what's causing the bug.

[Comment 14 Drew Winstel 2005-03-23 19:19:09 UTC]

I re-merged GTK+ with CFLAGS='-march=pentium4 -O2' and it seems to work.  I assume the removal of -mfpmath=sse,387 would do the trick for me as well.

[Comment 15 Don Seiler (RETIRED) 2005-03-24 08:04:28 UTC]

I'm closing this then.  Honestly, those CFLAGS were just insane.  I don't see a need to even notify gnome.
