Converting applets to support Wayland

[fossfreedom]

This is a tracking issue to focus on supporting wayland for budgie-extras applets and apps. All help is welcome

libxfce4windowing may help with the transition (python support via its gir python package, or using a vala vapi as per budgie-desktop). Similarly we need to look at layer-shell for positioning things https://github.com/wmww/gtk-layer-shell

Remember at a minimum all applets including 3rd party applets need to use budgie-2.0 as the target gir

Edit this issue and amend:

• [X] Add meson_option compile option for wayland - default for the moment is X11 https://github.com/UbuntuBudgie/budgie-extras/issues/474#issuecomment-2217146684
• [ ] budgie visualspace: wnck ref + upstream workspace support
• [ ] budgie dropby: wnck ref
• [ ] budgie shuffler: Needs focus on across the codebase / working with upstream
• [ ] budgie wpreviews: Needs focus on across the codebase / working with upstream
• [ ] budgie wswitcher: wnck ref + upstream workspace support
• [ ] budgie workspace stopwatch: wnck ref
• [ ] budgie showtime: wnck ref - needs gtklayershell
• [ ] budgie weather: needs gtklayershell
• [ ] budgie-quickchar: x11 reference and needs upstream shortcut support
• [ ] budgie-extras-daemon - global keyboard shortcuts are going to be handled very differently under wayland
• [X] budgie-applauncher: ~popover.set_default_size no longer exists as an api function~
• [ ] budgie-takeabreak: xrandr usage / Gdk.Display is used to get output names
• [X] budgie-brightness-controller ~- that uses xrandr which is X11 specific - so need to consider alternatives possibly like wrandr~ applet now just shows one bar under wayland
• [ ] budgie-countdown - this depends on settings-daemon power values - this maybe different in a wayland world
• [ ] budgie-rotation-lock - this depends on gnome-settings-daemon stuff ... not sure if mutter related stuff is involved
• [ ] budgie-keyboard-autoswitch - makes use of xdotool to get wmclass

All applets need testing under wayland - there will probably be others that need to be added to the above list.

To be tested:

• [X] budgie-applications-menu
• [X] budgie-clockworks
• [x] budgie-fuzzy-clock
• [X] budgie-kangaroo - it isn't using a popover - expecting a menu to be displayed - this works with the popover was a window... but now its a gtk-popover - tweaked so the menu pops up at the correct location but still should probably be revisited https://github.com/UbuntuBudgie/budgie-extras/issues/475
• [x] budgie-network-manager
• [X] budgie-quicknote
• [X] budgie-recently-used
• [X] budgie-common
• [X] budgie-wallstreet note - needs upstream support for the lockscreen and setting the image from the gsettings key

Additional applets outside of extras

• [x] budgie-indicator-applet

Additional considerations:

• [ ] popovers in python applets appear transparent when built-in theme is selected

I'll take the first item to add an option to compile applets with a wayland option. For the initial release all the applets/applications above will NOT be compiled and thus NOT available under wayland. Once support is available we can add in the applet.

meson option "for-wayland" is to be used within meson to differentiate between wayland and X11 specific compilation options.

budgie_dep is defined at the root meson.build level - so any applets should use this now in their specific meson.build rather than hardcode budgie-1.0

python apps should use this format to differentiate between v2 and v1 gir https://github.com/UbuntuBudgie/budgie-extras/blob/1e9ae39d6dcb1c8a7da8b34aef1a4978869e360f/budgie-app-launcher/src/budgie-app-launcher/AppLauncherApplet.py#L19

similar code could/showed by used for vala compilation ... and/or we can consider a config type #ifdef type way of doing things
