I just notices that both 3D switchers (Cover and Flip Switch) support key navigation. So this issue applies to the other ones. which window switcher are you using? This should be supported by all switchers. So it's probably a bug in the one you use. I've tested with every single one, and the only ones that support keyboard navigation are the 3D ones. For example: Breeze, Breeze dark, Grid, Previews, etc - they all ignore the keyboard arrows. I just have the default ones installed (haven't installed any one through GHNS) which cursor keys did you use? E.g. in Breeze (using a vertical list) the up/down arrows should be supported. Left/right though should not be supported. I've tested with all 4 arrow keys. I can confirm none of them work in any of the non-3D window switchers. Here's what I do: 1. Hold Alt 2. Press (and release) Tab 3. Try any arrow key Maybe there is some configuration missing? Maybe something related: If I set the screen edge feature (for example, on the left side) to show the window switcher (for example, Breeze or Grid), any of the arrow keys work either, and when I click a window it just highlights it, but there's no obvious way to select the window and dismiss the switcher. If I choose a 3D switcher, it is worse, because keys then don't work either, neither Enter or ESC, and I have to move the mouse again to that screen edge to dismiss the switcher. Just to make sure it wasn't something in my $HOME that was messing, I've created a new user, logged in with it, and the arrow keys don't work either. I can confirm this doesn't work for me. KDE Neon 5.8.5 / Framework 5.29 / Qt 5.7.0 It sounds like the QML based tabboxes aren't recieving the keypress events. The flip switch and cover switch are C++ desktop effects, which can hook the keyboard events themselves since they create their own window. https://github.com/KDE/kwin/blob/master/effects/flipswitch/flipswitch.cpp#L902 https://github.com/KDE/kwin/tree/master/effects/coverswitch This is where the QML based tabboxes events are handled. https://github.com/KDE/kwin/blob/master/tabbox/tabboxhandler.cpp#L618 If you do: PlasmaCore.Dialog { mainItem: Item { Keys.onPressed: {} } } then it works in the *preview* but does not work in the actual kwin popup. I wonder if it's because the popup isn't focused? PlasmaCore.Dialog is a QQuickWindow, which I don't think will do anything if it doesn't contain an activeFocusItem. https://github.com/qt/qtdeclarative/blob/dev/src/quick/items/qquickwindow.cpp#L1622 Did it work in the past? Did adding the eventFilter to support the mouse wheel break it? I don't remember if it used to work or not. https://github.com/KDE/kwin/commit/e9d20b80e9a79f514a219357d991092d83665350 I do know that the qml api changed, because a number of task switchers on GHNS no longer work. *** This bug has been marked as a duplicate of bug 370185 *** |
