Can I call the showdesktop by a shrotcut?

[knm100]

Sometimes, I need call the showdesktop fastly, I hope the showdesktop can be bonded to a shortcut.

You can set it up, but it's tricky. The problem is that there is currently no hotkey protocol in wayland so we need to use side channels. You can in theory setup your compositor to send an RT signal to sfwbar upon pressing a key combo and then add a trigger in sfwbar to minimize / restore windows upon receipt of the trigger.

I bonded the F10 to sent SIGUSR2 to sfwbar (compositor:labwc).

<keybind key="F10">
           <action name="Execute" command="killall -SIGUSR2 sfwbar" />
       </keybind>

set trigger in showdesktop.widget as the following code

TriggerAction "SIGUSR2", action = {
     if WidgetState(1)
        ShowWindows;
     else
        HideWindows;
   }

then the sfwabr crashed (no coredump) when I pressed F10.

SIGUSR2 is reserved for hide/show bar. Try using SIGRTMIN+1 instead. You also won't be able to use WidgetState here, since TriggerAction will call your code unattached to any widget, so you probably want to wrap the code in a function and have triggeraction call that function on a specific widget. I.e. Function ShowDesktop() { ... } TriggerAction "SIGRTMIN+", Fuction "MyWidget", "ShowDesktop"

I setted a trigger in sfwbar.conf
TriggerAction "SIGRTMIN+1", Exec "/home/knm/.config/sfwbar/power.sh"
typedkill -s SIGRTMIN+1 $(ps -A | grep sfwbar | awk '{print $1}') in a terminal

and confirmed that the trigger is ok, it can trigger the power.sh to run.
then, I change Exec "/home/knm/.config/sfwbar/power.sh" to Fuction "showdesktop.widget", "HideWindows"
but kill -s SIGRTMIN+1 $(ps -A | grep sfwbar | awk '{print $1}') can't trigger the Fuction HideWindows

The address in the function call (i.e. "showdesktop.widget") should be an id of a widget, not a widget config file. I.e. you need to a have widget declared in the layout section" layout { ... button 'mywidget' { ... } } Then you call Function "mywidget", "ShowDesktop"

setted a trigger in sfwbar.conf
TriggerAction "SIGRTMIN+1", Function "ShortcutCall", "ShowDesktop"
add the following Function to showdesktop.widget

Function ShowDesktop() {
     if WidgetState(1)
        ShowWindows;
      else
        HideWindows;
}

add widget id ShortcutCall in the behind of button

layout {
  button  'ShrotcutCall' {
------------------------
}

but it seem to trigger only HideWindows.

This should hopefully be fixed in the latest git. Also, most configs do have a default action of sigrtmin+1 bound to switcher next in the default config. So, it may be far to use sigrtmin+3.

the git rev r1776.d014394 still only trigger HideWindows.
