Kivy button implementation - how can I do that with my written code?

I'm newbie in python and kivy programming and to learn a bit more I've tried to make a small music player - it plays sound if I choose from balk list next to the pane - but I can't get that pane itself to work - I need some explanation how to achieve that and the similair subjects aren't very helpful. I've tried to get exactly 4 buttons in grip layout to work - but without any effect.Here is my code in pythonkivy:

Not sure what you are asking. I see you have defined 4 buttons in aGridLayout, but only assigned anon_pressaction to one of them. So the three without any action defined will haveno effect. Please be clear about what your question is.

I know that must use on_press at each of those buttons but my problem is to how to write a correct functions to them - my buttons are as follows previous song, pause, play and next song - I thinking myself how to do that but l'm failing badly every try
– AnotherNewbie
Nov 16 '18 at 6:14
So you start by writing a method inPlayerfor each of those buttons. Use the documentation for help. For example, thepausemethod would probably call thestop()method fromSoundand maybe theget_pos()method if you wantplayto continue from the paused point, Thepreviousandnextmethods are simply stopping any currently playing sound and callingSoundLoaderon the next or previous track. You will probably need yourtrackslist to be an instance variable instead of local toload_tracks.
– John Anderson
Nov 16 '18 at 15:24
Thanks John I'll immediately go try your tips into my code - I didn't think about those methods and I was trying to write functions direct into "load_tracks" - I see my mistakes now. Thank you for your time and have nice weekend. I'll let you know when I'm done.

Not sure what you are asking. I see you have defined 4 buttons in aGridLayout, but only assigned anon_pressaction to one of them. So the three without any action defined will haveno effect. Please be clear about what your question is.

Nov 15 '18 at 3:06
I know that must use on_press at each of those buttons but my problem is to how to write a correct functions to them - my buttons are as follows previous song, pause, play and next song - I thinking myself how to do that but l'm failing badly every try
– AnotherNewbie
Nov 16 '18 at 6:14
So you start by writing a method inPlayerfor each of those buttons. Use the documentation for help. For example, thepausemethod would probably call thestop()method fromSoundand maybe theget_pos()method if you wantplayto continue from the paused point, Thepreviousandnextmethods are simply stopping any currently playing sound and callingSoundLoaderon the next or previous track. You will probably need yourtrackslist to be an instance variable instead of local toload_tracks.
– John Anderson
Nov 16 '18 at 15:24
Thanks John I'll immediately go try your tips into my code - I didn't think about those methods and I was trying to write functions direct into "load_tracks" - I see my mistakes now. Thank you for your time and have nice weekend. I'll let you know when I'm done.

Label:

What have I changed - at first I replace a list of my tracks to head class - that makes it available for all functions and make possible to write functions to all buttons in my small interface - I've used in kv file a link to background image what makes it a bit prettier, and as bonus I've written a volume control function and I've created a bar for it to read constantly the value whatever it is in range from 0 to 100

What have I changed - at first I replace a list of my tracks to head class - that makes it available for all functions and make possible to write functions to all buttons in my small interface - I've used in kv file a link to background image what makes it a bit prettier, and as bonus I've written a volume control function and I've created a bar for it to read constantly the value whatever it is in range from 0 to 100

What have I changed - at first I replace a list of my tracks to head class - that makes it available for all functions and make possible to write functions to all buttons in my small interface - I've used in kv file a link to background image what makes it a bit prettier, and as bonus I've written a volume control function and I've created a bar for it to read constantly the value whatever it is in range from 0 to 100

Not sure what you are asking. I see you have defined 4 buttons in a
GridLayout, but only assigned anon_pressaction to one of them. So the three without any action defined will haveno effect. Please be clear about what your question is.– John Anderson

I know that must use on_press at each of those buttons but my problem is to how to write a correct functions to them - my buttons are as follows previous song, pause, play and next song - I thinking myself how to do that but l'm failing badly every try
– AnotherNewbie

So you start by writing a method in
Playerfor each of those buttons. Use the documentation for help. For example, thepausemethod would probably call thestop()method fromSoundand maybe theget_pos()method if you wantplayto continue from the paused point, Thepreviousandnextmethods are simply stopping any currently playing sound and callingSoundLoaderon the next or previous track. You will probably need yourtrackslist to be an instance variable instead of local toload_tracks.– John Anderson
Nov 16 '18 at 15:24
Thanks John I'll immediately go try your tips into my code - I didn't think about those methods and I was trying to write functions direct into "load_tracks" - I see my mistakes now. Thank you for your time and have nice weekend. I'll let you know when I'm done.
