who can reproduce mousewheel scrolling issues?

[Olivier Sessink]

can you insert this line: g_print("doc_scroll_event_lcb,
event->state=%d,
event->direction=%d\n",event->state,event->direction); in
doc_scroll_event_lcb and see what the output is? Olivier

Fixed in revision 7668.

good job!

Please check that I haven't broken scrolling for other people ;-)

I've just modified it slightly so it will compile on older gtk releases.

- When I scroll the wheel away from me (up?) the view zooms in.
- When I scroll the wheel towards me (down?), the view zooms out

the weird thing is that smooth scrolling was introduced in gtk 3.4 (it
seems?), and the original bug report was before gtk 3.4 (user reports
Debian wheezy in https://bugzilla.gnome.org/show_bug.cgi?id=677015 but
possibly that was with gtk-3.3 which was available in wheezy)....?

doc_scroll_event_lcb, event->state16, event->direction=4

$2 = {type = GDK_SCROLL, window = 0xaacea0, send_event = 0 '\000',
time = 365367630, x = 702.40423583984375, y = 295.94927978515625,
state = 16, direction = GDK_SCROLL_SMOOTH, device = 0x6b4890,
x_root = 863.40423583984375, y_root = 374.94927978515625, delta_x = 0,
delta_y = 0}

gdk3 docs seems to point to delta_x and delta_y, alternatively
gdk_event_get_scroll_deltas(), but that function needs GdkEvent rather
than GdkEventScroll.

A bit of testing seems to confirm it. The only very annoying thing is
that for the first scroll event, delta_x and delta_y are always zero
(comment on the stackoverflow link below).

I also found this one while googling gdk_event_get_scroll_deltas():
http://stackoverflow.com/questions/11775161/gtk3-get-mouse-scroll-direction


I'll check in a fix.

And just to check that scrolling is done consistently:
- When I scroll the wheel away from me (up?) the view zooms in.
- When I scroll the wheel towards me (down?), the view zooms out

various people have reported issues with control-mousewheel not zooming
in and out

Is there somebody on the list who can reproduce this?

Confirmed.

Hi all,

Is there somebody on the list who can reproduce this?
