As said in summary, it would be need to be able to scroll the windows horizontal using the mousewheel above the horizontal scrollbar. I guess there as no disadvantage in doing so and all good toolkits that I know (i.e. Gtk and Qt) do it this way. I don't know about the Win32 Toolkit.

Haven't been able to find anything in Win2000 that does this. Native scrollbars definitely don't. But that's not to say it's a bad idea.

Would be nice, but strikes me as somewhat difficult compared to the benefit.

TextPad 4.4 on windows 2000 does just that.

I want this feature even if using a modifier key. e.g. shift + mouse wheel

I'd like both. Optionally (because in some cases it can be annoying) scroll horizontally while hovering over a horizontal scrollbar, and option to scroll horizontally as mousewheel action in prefs. The usual behavior is up=right, down=left (think X, Y values from algebra). I will note that this behavior is not expected of Windows programs, it is only supported in apps that have adaptive code written in. Not even IE5.5 appears to support this; this would be a great place to have the advantage.

Actually, the behavior in Textpad seems to be the opposite of what I thought. Maybe this should be an option too. Something like "reverse horizontal action" with the default being the same as Textpad.

Seems to me that it would make more sense for scrolling down on the wheel to move right on the page; page content goes left to right, as they do up to down. That way, scrolling down always progresses further into your content and up always takes you back.

Related, but different bug: Bug 143038 (using a modifier key instead of hover).

Gtk behaviour is down scrolls to the right, which is consistent with reading order. This bug is a problem of feeling native, too. See bug 176548, which seems to be the same with the only difference that proposed solution is to use gtk widgets.

(In reply to comment #13) > Gtk behaviour is down scrolls to the right, which is consistent with reading > order. This bug is a problem of feeling native, too. That would be fine with me. Opera also does this (down scrolls to the right). I just gave quick code example how it should be done natively in Windows. Just reverse the condition. > See bug 176548, which seems to be the same with the only difference that > proposed solution is to use gtk widgets. I have seen it -- seems to me that you have accidentaly posted the wrong number. To me it doesn't seem related to this bug. Moreover, related to bug #143038 I agree about having Ctrl+wheel shortcut for Zoom +/- like in Photoshop and Opera, but I believe that having modifier keys for changing scroll direction is somehow inconsistent with good UI design. Hover is more intuitive and if you already reach to press additional key you may as well use left/right arrow for horizontal scrolling instead of wheel. Please someone enlighten me -- why use gtk under windows for this feature if native solution is so simple?

Sorry, I meant bug 176458. > Please someone enlighten me -- why use gtk under windows for this feature if > native solution is so simple? I had linux in mind. As far as linux is concerned default builds use gtk2 so this should not be a problem - only events seem to be hijacked by mozilla. I think bug 176458 is about fixing the bug for linux, and this one is about a cross platform enhancement. I'm voting for both.

I'm voting for both. If I understand correctly this bug # is about making the feature available for Winodws version of the browser. I have tried to contribute native solution but it seems that the developers do not care too much (please correct me I am being overly mild in expressing myself).

In any event, team up with Ryner or assign the bug to yourself, attach a patch and mark it for review - see what happens with it.

This is the behavior of various GTK+ applications, don't know if it is an actual behavior of GTK+ itself.

I'll not agree with you. EVERY horizontal scrollbar can be used with scrollwheel.

Has there been any progress on this? Scrolling above any scroll-bar should activate that scroll-bar under GTK, so scrolling over a horizontal scroll-bar should scroll horizontally. Current behaviour is inconsistent with all other GTK2 applications.

This is clearly a bug since the scroll bar is not catching events when mouse is over it. Even clicking on the scroll bar does not make it catch mouse scroll events afterwards. This bug is now old enough to be wearing long trousers , any chance of something like the code posted in #12 getting applied?

Hello Bugzilla. My issue is happening since Firefox 4.0, OS: windows xp. Optical 4D Mouse A4Tech WOP-35: [url]http://www.a4tech.com/product.asp?cid=1&scid=8&id=22[/url] Since Firefox 4, the Horizontal wheel doesn't works properly, this duplicates the function of the vertical wheel; ie, the Horizontal wheel scrolls vertically, although "horizontal navigation bar" appears on screen. Nevertheless, the horizontal-wheel worked properly until FF3.6.x. But, not only that. The horizontal wheel no longer works to navigate through facebook pictures, iimmgg.com images (on galleries), or similar web, how it worked before, until FF3.6 :cry: I have enabled: the enhanced dual wheel mode, in the last driver installed (v7.80). And I tried with a new firefox profile, and its safe mode. But the issue persists.

This is still not working on firefox 12 Linux version

So this bug is already 14 years old and nobody has fixed it nor stated a reason to close it. This behavior is specially annoying for mouse users because in addition to not being able to scroll on the horizontal scrollbar, shift+scroll doesn't work for this as it does in most programs, so the only way to scroll horizontally is either clicking on the bar or using the auto-scroll, which doesn't give you as much control and precision as the scrollwheel provides. Is there any reason this behavior shouldn't be implemented? If so, would it be possible to get it as an addon? PS: Could someone please develop this as an addon (if possible)? I'm not a developer.

Hi cousteau and blog. The extension or addon to Firefox, that improves the performance without being automatic scrolling is: "Scrollbar Anywhere". Since Gnu/Linux distros if working my horizontal whell as expected. Nevertheless, not the Automatic Scrolling on whole system.

(In reply to Turson from comment #31) > "Scrollbar Anywhere". Not exactly what I wanted. Nevertheless, I've found another extension, "Horizontal Scroll", that does exactly what is being requested. Finally!

thanks Cousteau ! That finally provides a workaround to fix this bug and got it noticed here. Many thanks for the heads up. Maybe one day it will be integrated in FFx.
