Add parameters to callback function

DasEarl · Postby **DasEarl** » 19 Aug 2015 14:02

Hello,

I made a script to seek through my videos.
Since I don't know how to give a callback
function a parameter, my code looks like this:

Code: Select all

require 'common'

function descriptor ()
	return {title = "Seek"; version = "0.1"; author = "DasEarl"; capabilities = {}}
end

function activate()
	print("Seek started")
	dlg = vlc.dialog("Seeker")
	dlg:add_button("10%", seek_10, 1, 1, 1, 1)
	dlg:add_button("20%", seek_20, 1, 2, 1, 1)
	dlg:add_button("30%", seek_30, 1, 3, 1, 1)
	dlg:add_button("40%", seek_40, 1, 4, 1, 1)
	dlg:add_button("50%", seek_50, 1, 5, 1, 1)
	dlg:add_button("60%", seek_60, 1, 6, 1, 1)
	dlg:add_button("70%", seek_70, 1, 7, 1, 1)
	dlg:add_button("80%", seek_80, 1, 8, 1, 1)
	dlg:add_button("90%", seek_90, 1, 9, 1, 1)
end

function seek_90()
	common.seek("90%")
end

function seek_80()
	common.seek("80%")
end

function seek_70()
	common.seek("70%")
end

function seek_60()
	common.seek("60%")
end

function seek_50()
	common.seek("50%")
end

function seek_40()
	common.seek("40%")
end

function seek_30()
	common.seek("30%")
end

function seek_20()
	common.seek("20%")
end

function seek_10()
	common.seek("10%")
end

function deactivate()
	print("Seek stopped")
end

function close()
	print("Seek closed")
	vlc.deactivate()
end

calling

Code: Select all

dlg:add_button("10%", seek(10), 1, 9, 1, 1)

does not work

Thanks for you help

Try this:

Code: Select all

   dlg:add_button("10%", function() seek(10) end, 1, 1, 1, 1)

function seek(position)
   common.seek(position.."%")
end

	print("Seek closed")
	vlc.deactivate()
end
