Hi,
This PR adds multi-purpose customizable widgets to wf-panel:

  • multi-purpose: music player, backlight (see configuration examples below), and hopefully other things I haven't think of yet…
  • customizable: icon, default or dynamic tooltip, mouse buttons and scroll actions can be set by the user.

These are merely 'super'-launchers with a basic widget look (button-like, no animation) and dedicated commands for mouse button/srolll actions and tooltip.
I made this to fit my needs but I hope it can be useful to other wf-shell users as well; it may also be a workaround to issue #22.

Configuration (in wf-shell.ini):
customizables_size = <int>
customizables_spacing = <int>
customizables_invert = <bool>
custom_label_<name> = <string> (mandatory)
custom_icon_<name> = <string>
custom_btn[1-3]_cmd_<name> = <string>
custom_scr_[up|dn]_cmd_<name> = <string>
custom_tooltip_cmd_<name> = <string>

  • customizables_* options impact all customizables widgets
  • custom_*_<name> options are related to custom_label_<name> widget

Important note about custom_tooltip_cmd:
This spawns a synchronous command, therefore waits for it to exit; so be careful with this command.

Configuration example:
customizables_size = 16
customizables_spacing = 2
customizables_invert = true

custom_label_1 = mpc
custom_icon_1 = /usr/share/icons/Adwaita/16x16/emblems/emblem-music-symbolic.symbolic.png
custom_btn1_cmd_1 = mpc toggle
custom_btn2_cmd_1 = mpc consume
custom_btn3_cmd_1 = sonata
custom_scr_up_cmd_1 = mpc seek -00:00:10
custom_scr_dn_cmd_1 = mpc seek +00:00:10
custom_tooltip_cmd_1 = mpc current

custom_label_2 = backlight
custom_icon_2 = /usr/share/icons/Adwaita/16x16/devices/video-display-symbolic.symbolic.png
custom_btn1_cmd_2 = brightnessctl --device=intel_backlight set 1
custom_btn2_cmd_2 = killall kanshi || /usr/bin/kanshi
custom_btn3_cmd_2 = wdisplays
custom_scr_up_cmd_2 = brightnessctl --device=intel_backlight set +1%
custom_scr_dn_cmd_2 = brightnessctl --device=intel_backlight set 1%-
custom_tooltip_cmd_2 = brightnessctl --device=intel_backlight --machine-readable info | cut -d, -f4

Coding notes:
I initially tried to inherit from Launchers but got stuck by LauncherInfo pure abstract struct; then I had either to modify the related code, or create new (well, it's almost a copy of Launchers…) dedicated struct/class and let mainteners decide which way is better ;-).
I tried to follow coding style and indentation found in other files but I may have missed some things.

It has been quite a while I haven't programmed in C++ and I've learnt a lot by reading the existing code and making this!

Many thanks to Wayfire contributors for this great WM!
Cheers!

Sorry for the long delay, looks good overall, and makes for an interesting widget.

custom sounds quite generic to me. Maybe custom-buttons ?

wf-options need to be created after loading the config file, which happens before widgets are initialized, but it won't work before that :)

this doesn't seem to be doing anything, maybe we should remove it?

This is a cool idea, hadn't thought about it, +1

what about

[customizables]
size = auto
spacing = 10
invert=false

uptime_pretext = "uptime: "
uptime_text = 0 ; gets ovewritten by uptime_text_command
umtime_text_command = uptime
uptime_infront_icon = /some/icon/path.jpg
uptime_refresh_speed = 3s
uptime_btn1 = alacritty --execute echo "some text with uptime information"
uptime_tooltip = uptime

something similar to polybar modules where you can specify a command to calculate the text by running a command repeatedly. I also think you could have a customizables section this in my opinion improves readability and they could possibly be implemented into the dock as well

Hi, thanks for your work here. I wonder if this will include a tray or make it possible? I did want to comment on one thing I noticed:

The style for the xml files isn't enforced by CI, but I would like to see whitespace style consistency. Here, tabs should be used, not spaces.
