Right way to call a function from mouse callback

[Gibranlp]

What is the right implementation of mouse callback on functions?

I have already imported qtile

from libqtile import qtile

I have a working function, called by key shortcut that works fine, but hen i use mouse callbacks i just dont know how to make it work.

foo();

I have tried this so far on mouse callbacks

- mouse_callbacks={'Button1':qtile.cmd_spawn(foo)}

which gives the error:

AttributeError: 'NoneType' object has no attribute 'cmd_spawn'

I have also tried

- mouse_callbacks={'Button1':qtile.function(foo)}

and  i get the error:

 mouse_callbacks={'Button1':qtile.function(set_rand_wallpaper)},
AttributeError: 'NoneType' object has no attribute 'function'

I have tryed with lazy object which i know now that are not callable,

mouse_callbacks={'Button1':lazy.function(foo)}

Can anyone point me in the right direction?

thanks

Writing it like that means you're binding the result of `qtile.cmd_spawn(foo)` to the button.

You can do it like this:

mouse_callbacks={'Button1': lambda: qtile.function(foo)}

Hit send too soon. Meant to say:

mouse_callbacks={'Button1': lambda: qtile.cmd_spawn(foo)}

I do wonder if we should allow mouse callbacks to take lazy objects too...

[Gibranlp]

When using lambda:

mouse_callbacks={'Button1':lambda: qtile.cmd_spawn(foo)}

The function is just never called

[Gibranlp]

I got it working now:

mouse_callbacks={'Button1':lambda: qtile.cmd_function(foo)},

the cmd_function is to be called. now it works.

Thanks

Sorry. Missed the part in your first message where you said foo was a function. 

Glad you got it working.
