I realized that due to e10s mochitests disabled, we won't test the default actions of wheel events without APZ. I manually ran the test without non-e10s mochitests. Then, I confirmed that it's all green. On the other hand, there is a known bug in the patch. The multiplier pref for X axis is applied to deltaY if the wheel event should be treated as horizontal scroll. So, WheelEvent.deltaY may see odd delta value with it especially when the multiplier X is negative (meaning scroll direction is reversed) but multiplier Y is positive.

Could you explain this. Currently shift+vertical wheel is back-forward.
Does this new behavior override that feature always or only when it is
enabled explicitly?
How is shift+horizontal supposed to work for back-forward if
shift+vertical is for scrolling? One often gets both horizontal and
vertical scrolling when using touchpad.

If so, perhaps make the ctor take WidgetWheelEvent& and store using that

Comment on attachment 8915954 Bug 143038 Make users can scroll contents horizontally with vertical wheel operation with a modifier https://reviewboard.mozilla.org/r/186794/#review193228 Because the tests set default action of both without any modifier and with shift to "scroll": > default: 1, with_shift: 1, with_control: 3 Therefore, even if the new pref overrides "default"'s default action, it should be ignored (i.e., default action of with_shift should be executed) since the wheel operation is not only for vertical-wheel. In other words, if with_shift is 2 as the default settings of non-macOS platforms, the diagonal wheel operation with Shift should cause navigating history. However, it's impossible to test it with this automated test. > What these numbers are? 1, 2, 3? Please add some comment Okay, I'll replace them with constants. > I don't understand this sentence. I meant "If only the modifier to trreat vertical wheel as horizontal scroll is active," > This sounds wrong. If the pref is set, and modifier is pressed, why should viewport scroll ever horizontally? I don't see such behavior in Chrome on Windows On macOS, we may receive diagonal wheel operation events.

You change the ordering of whether action is first checked for plugin or

[Bug 1228250]
Created attachment 8915954 Bug 143038 Make users can scroll contents horizontally with vertical wheel operation with a modifier This patch declares a new pref, "mousewheel.modifier_to_treat_vertical_wheel_as_horizontal_scroll", this takes a keycode of modifier keys as its value. The default value is 16 (NS_VK_SHIFT) on Windows, Linux and Android and 0 (meaning disabled) on macOS. The reason why this new feature is disabled on macOS is, if user turns vertical wheel of mice with Shift key, macOS notifies us of horizontal scroll events. So, we don't need to care this feature by ourselves on macOS. If a modifier keycode is specified to the pref as expected, EventStateManager and EventStateManager::WheelPrefs treats vertical wheel operation as horizontal scroll when coming wheel event without the modifier causes scroll. In such case, EventStateManager::WheelPrefs::NeedToTreatAsHorizontalScroll() returns true. Otherwise, false. If this returns true, default action handler of wheel events such as EventStateManager::PostHandleEvent() and IAPZCTreeManager::ReceiveInputEvent() swaps deltaX values and deltaY values of coming wheel event temporarily and restore them. AutoTemporarilyWheelDeltaSwapper in WheelHandlingHelper guarantees this restoring. So, this patch does NOT change any wheel event information on web apps. Only changes its default action. This is same behavior as Chromium. Note that with this patch, users cannot navigate the tab's history with Shift + vertical-wheel in the default settings. However, I guess that the usage of this feature is less than the number of users who wants to scroll contents horizontally with vertical mouse wheel. Of course, Shift + horizontal-wheel is available for navigating tab's history even after this change.

Okay, now, I think that 2-2 is the best here because: 1. if we ban diagonal wheel events with specific modifier key, horizontal scroll might be too slow if the device can cause diagonal scroll easily (even if user expects only vertical scroll). 2. if we also take deltaX as horizontal scroll, horizontal scroll might be too fast if user does diagonal scroll. Then, we can treat the new action as simple default action.

On Windows, native event doesn't support diagonal scroll with an event. So, this case never occurs on Windows actually. (If user tries to scroll content diagonally, both vertical wheel event and horizontal wheel event are fired separately.) Although, it could occur with some touchscreen. However, I don't see wheel events when I scroll content in Gecko with my notebook's touchscreen. (Pan gesture could fire wheel events, but I'm not familiar with this path: https://searchfox.org/mozilla- central/rev/1a4a26905f923458679a59a4be1e455ebc53c333/widget/windows/nsWinGesture.cpp#393,409-410,412-413 ) I'm not sure about GTK. GTK3's event has both delta values in an event. So, it could support diagonal scroll, but I don't have environment that Linux is installed on real machine (not virtual machine). Anyway, I don't think that we should use this feature when the user's device is obviously non-legacy pointing device, i.e., it supports diagonal scroll.

Could we somehow > enable it on mouse input only, and not touchpad? Unfortunately, on any platforms, we cannot check if mouse scroll event came from what kind of device. There are some options: 1. Take current approach -- treat "pure" vertical wheel operation as horizontal scroll and 1-1. Handle deltaX as is (current approach). 1-2. Handle deltaX as vertical scroll (I don't like this and incompatible with Chrome). 1-3. Ignore deltaX, so, if only deltaX is non-zero, does nothing. 2. Treat any vertical wheel operation as horizontal scroll (even if it's diagonal operation) and/but 2-1. Handle deltaX as vertical scroll (same as 1-2). 2-2. Ignore deltaX (same as 1-3). If user operates wheel diagonally but native events come separately, it might be the best to ignore deltaX. E.g., we can avoid performing 2 default actions (e.g., both horizontal scroll and navigating history), but this means that the default action will always be ignored if it matches with new pref's modifier. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I see, on linux Chrome has odd behavior where it seems to allow vertical scrolling when diagonal scrolling is done. That behavior is really weird when one uses it. Makes scrolling feel like all broken since viewport is scrolled somewhat randomly.

What does Chrome actually report in delta values? Looks like that IE/Edge doesn't have this feature since Shift+wheel causes navigating history like us. Chrome just swaps default action (i.e., not touching DOM event values). I wonder, wheel related events are cancelable, that means that it does NOT represent default action's behavior. So, perhaps, we can just take the Chrome's behavior? (Even if web apps check their implementation only with Chrome, it won't cause any problem only on Firefox.) That's not ideal behavior from a point of view of DOM events, but low risk approach in the real world.

[Bug 1228250]
Shift+Scroll to scroll horizontally is still missing. This might seem like a small feature to have, but it actually has profound impact. First of all, I belive the majority of mice still only have a vertical scroll wheel. At our university, every mouse falls into that category. However, the major problem is providing a consistent interaction with horizontally scrolling containers across platforms/browsers. If one has to rely on a vertical scroll wheel, the approach would be listening for the `wheel` event and use `event.deltaY` for setting `scrollLeft` when `event.shiftKey === true`. Now this won’t lead to pleasent results right away since these deltas yield vastly different values across devices/browsers. Is it a trackpad? Does it fire the event very often? Is the delta very big or very small? Is the inertial scrolling behavior? In short, re-implementing scrolling behavior is very hard. Turning a scroll wheel once results in roughly the same scrolling distance when comparing Chrome and Firefox. However the events’ delta values are different. What does this have to do with this issue? Since there is no Shift+Scroll for horizontal scrolling, providing users with a way to do so also requires to re-implemented scrolling. Users need a way of interacting with horizontally overflowing elements by scrolling natively. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I know it's not qt, but qt has this notion of QWheelEvent::DefaultDeltasPerStep – maybe gtk has that too? Anyway, I recently implemented a fix for a problem in the linux KDE application gwenview, where, when you used CTRL+Touchpad_scroll to zoom in/out, it was horribly sensitive (see here for bug/patch https://bugs.kde.org/show_bug.cgi?id=378584#c7). For the fix we would always accumulate deltas upon triggered events and only perform the action once the accumulated delta is greater than or equal to QWheelEvent::DefaultDeltasPerStep (at the same time resetting the accumulated delta to 0). Using the scroll wheel, the emitted delta is exactly QWheelEvent::DefaultDeltasPerStep, such that the action is performed at each turn of the wheel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have never owned a mouse with a horizontal scroll wheel, only ones with a tiltable a scroll wheel. It's horrible having to use those for scrolling horizontally as you have to press them several times rather than rotate a wheel. It feels much more natural to use the up/down wheel with a modifier key pressed. Furthermore, this is standard behavior in quite a number of applications; to the ones already mentioned (Chrome, gimp, evince) I'd like to add Inkscape, Scribus, LibreOffice. For other applications like konqueror, okular, gwenview, qtcreator it's Alt+Scroll Wheel, but still it's possible. I frequently find myself longing for that feature because I (have to) use large zoom levels and having to grab the scroll bar or scroll with Left/Right keys is much less comfortable. So I would be really happy if someone could provide a simple working solution!

> How many people still want this feature? In these days, most pointing devices support horizontal scroll with tilt wheel or swipe gesture. Well, since you asked, here's the history of my horizontal scrolling capability. First, my desktop still has a 1-dimensional wheel. After all, mice aren't the kind of gadget that have compelling reasons for people to upgrade them every six months. On the other hand, my laptop is my primary computer, and I've recently upgraded to one with two-finger scrolling (in 2D). In fact, I've even written a Firefox extension (Scrolling Gestures) to take advantage of the horizontal scrolling capability. As a result, I've been untrained from using shift+scrolling and this feature isn't as important to me as it was a year ago (when each of my computers had only 1D scrolling). > scrollable element implemented with JS is scroll normally with this patch Do you mean, it will appear to JavaScript like Shift+Up and down? Bear in mind that there are two separate events for capturing wheel events; one ignores the axis and the other does not. There is at least one webapp (pressdisplay.com) that requires shift+vertical scrolling because of this. Here's a JSfiddle that demonstrates this: http://jsfiddle.net/SXAUx/7/ . Also, for the axis-capable event, shift- scrolling in Chrome reports only horizontal wheel events (even for shift+horizontal). > And I'd like to know if other browsers have this feature? Chrome has this feature. It also works in some other software, at least on Linux, like Evince (the GNOME PDF viewer). I still think this feature is useful, even if I don't need it myself. However, I don't maintain Mozilla's scrolling code, so (speaking only for myself) if it's really too problematic to implement, I'm willing to concede. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1228250]
Comment on attachment 8369358 Horizontal Scrolling with Mouse wheel+ modifier key I believe that you want to swap the scroll direction completely. However, your patch just swap the scroll direction of default action of wheel event. E.g., scrollable element implemented with JS is scroll normally with this patch. You need to swap the delta values before handling all of them. I.e., You need to swap them in PreHandleEvent() (after applying delta_multiplier prefs?). And also you need to swap lineOrPageDeltaX and lineOrPageDeltay at same time. Finally, you might need to swap overflowDeltaX and overflowDeltay at the end of PostHandleEvent(). Additionally, you have to test new behavior with automated tests: * Add new function to test if deltaX/deltaY are swapped in DOM event level. http://mxr.mozilla.org/mozilla-central/source/dom/events/test/test_dom_wheel_event.html?force=1 * doTestScroll() should be run again with swapped pref. And also you need to test overflowX/Y are swapped correctly. http://mxr.mozilla.org/mozilla-central/source/dom/events/test/window_wheel_default_action.html?force=1 * Please test it with native scroll event (this is now only available on Windows) http://mxr.mozilla.org/mozilla-central/source/widget/tests/window_mouse_scroll_win.html?force=1 However, I don't think that this is good patch because this may make the code difficult to maintain. Therefore, basically, I don't agree with adding this feature suggested by this bug. How many people still want this feature? In these days, most pointing devices support horizontal scroll with tilt wheel or swipe gesture. Why this isn't enabled in default settings? These fact means that this makes the code complicated only for a few users. I'm not sure if this is worthwhile to fix this bug. I want to suggest this bug marked as WONTFIX. Could you explain why do we need to fix this bug even with such cost and appending risk? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It depends on that we should give priority to compatibility with Chrome or our traditional behavior. We should ask somebody who works on UX of Firefox for default setting change.

(In reply to nandhp from comment #75) > First, my desktop still has a 1-dimensional wheel. After all, mice aren't > the kind of gadget that have compelling reasons for people to upgrade them > every six months. Well, but horizontal scroll is supported on Vista or later with native message. So, all major platforms now support it in native level. I.e., the problem occurs only on WinXP or with mice or touchpads which don't support horizontal scroll. On such environment, the users really want a way of horizontal scroll by their device's vertical scroll operation? I'm not sure the strong reason why we need to implement this. Additionally, I think that most web developers don't design such pages which needs to be scrolled horizontally. Actually, I don't use horizontal scroll in most web pages... > > scrollable element implemented with JS is scroll normally with this patch > > Do you mean, it will appear to JavaScript like Shift+Up and down? I meant that some web pages have their own scrollbar for sub frames which handle DOM wheel events. I believe that users want to scroll them horizontally with the new setting. However, if it's enabled in default settings of Shift or something, web pages never handle raw deltaX/Y values with the modifier state. Of course, it's bad thing, though... > Bear in > mind that there are two separate events for capturing wheel events; one > ignores the axis and the other does not.

On Mac, we support diagonal wheel event (i.e., both deltaX and deltaY may be not 0 of a wheel event). So, discarding native event's deltaY information does not make sense. So, just swapping deltaX and deltaY does make sense to me. > > And I'd like to know if other browsers have this feature? > > Chrome has this feature.

Just wanna say that EVERYTHING @Jan Keromnes has answered is EXACTLY what I'm feeling. I've been a loyal Firefox user since around 2001. I live the net through it. In the very least, being able to *enable* this behaviour - if only through "about:config" - is very, very important to power users. PS: It's not a good idea to assume that users will have mice with horizontal scroll, nor is it guaranteed that if they have horz-scroll on the mouse, that they'll actually use it that way. I have a Logitech G700 and I've mapped copy/paste to my left/right horz-scroll cause that's what I use practically once every two minutes while working.

Comment on attachment 8369358 Horizontal Scrolling with Mouse wheel+ modifier key Review of attachment 8369358: - Currently, mousewheel pref actions can be set to 0:do nothing, 1:normal scroll, 2:navigate history and 3:zoom. This patch adds option 4 to mousewheel pref actions in order to swap X and Y scroll deltas. Example: Change "mousewheel.with_shift.action" to 4 so that Shift+Scroll scrolls horizontally. André, can you take a look please? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228250 Title: [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1228250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi! I'm also a Firefox loyalist and have been searching desperately for this functionality. I've seen all sorts of options that *sort of* indicate that it *might* be available but nothing works. Some webpages I've viewed: - https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling#Preferences_for_customizing_delta_values_and_default_action - http://forums.mozillazine.org/viewtopic.php?f=23&t=2072387 - https://wiki.mozilla.org/Gecko:Mouse_Wheel_Scrolling - http://forums.mozillazine.org/viewtopic.php?f=38&p=12546047 These pages are related to this feature request but none of them provide an actual solution. User @Skewer's original comment near the top of this issue says: > Note that the traditional defaults are: > Mouse wheel: Scroll vertically > Ctrl+wheel: Zoom > Shift+wheel: Pan (scroll horizontally) The shift+wheel action (Pan / scroll horizontally) is *exactly* what I'm looking for.

Any chance for a binary patch for Win32? :) Thanks. Though the best way is building Mozilla with patch, here is yet another implementation by XUL. This also implements Bug 71464 imperfectly. This will be XPInstalled as add-on by simply opening it in Mozilla. Only works with window, frame and message-pane in Mozilla but none of other widgets like texbox although original patch works with almost every scrollable widget. If you want to change modifier key, amount of scroll or direction, edit mozilla's chrome/whscroll/content/whscrollOverlay.xul manualy. The value of mousewheel.with[your modifier]key.action must be 0 or 1 when using as horizontal scroll trigger. Uninstallation is done manualy delete the directory named `whscroll' and remove descriptions about whscroll in chrome.rdf and those lines in some overlayinfo/*/content/*.rdf files in Mozilla's chrome directory.

[Bug 1228250] [NEW] [Shift + Mouse-Scroll-Wheel] Does NOT Scroll Horizontally
Public bug reported:
In Chromium, I can scroll horizontally using my mouse-wheel by holding
down the shift key while scrolling the mouse wheel.
Firefox is missing this very convenient page-navigation short-cut.
Use Case:
As my eyes age, I find myself always scaling up the web pages I read (by
holding down crtl and scrolling my mouse wheel).
Doing this, often makes the page exceed the width of my monitor (hiding
the right-side of the text I want to read) and produces a horizontal
scroll bar at the bottom of the page.
At this point, since I've already used ctrl-scroll-mouse-wheel to
magnify the page, it would be wonderful if I could use shift-scroll-
mouse-wheel to horizontally-scroll the magnified page and therefore
center the (previously cropped) text that I am wanting to read.
