Shift+mouse wheel should scroll sideways

mgunyho commented 1 year ago

I think it's fairly standard for applications to scroll sideways with shift + scroll wheel. I would like to have this behavior for the ScrollView.

Related to #1280 I suppose.

That should be easy to do in the items/flickable.rs file when handling the wheel event we could check if shift is pressed. (We do that check also when clicking on a Textinput)

@ogoffart, some mouses has scroll left and scroll right buttons, too. It is done by tilting the wheel. I guess it is same as shift+wheel. Just FYI.

@DaMilyutin Our Flickable and ScrollView already support that

I tried to look at what other framework do to see if this is really the case. (i'm on linux)

Firefox and Chromium makes Shift + vertical scroll an horizontal scroll. (But shift + horizontal scroll stays a horizontal scroll)
Qt ScrollArea / QML's flickable don't handle that
But KDE application use Alt + scroll to reverse the scrolling direction (horizontal or horizontal) in most of their widget.
Gtk application seems to use Shift + Scroll to reverse the scroll direction
From the macos docs, i think they use shift + wheel to scroll horizontally
On windows it depends on the apps.

So i'm tempted to say we can indeed do shift + wheel to invert scroll direction
