Changing Button image from lua script

[danward79]

Hi

Does anyone know how to change the image in a button from the lua script file? What I need is to change the image between the active and inactive images.

I have been trying to do it using the State:Zone, in the ID Tag box, but it does not work.

Below is my LUA, it is the last bit with MP.Zone I need to get working to change the button state.


function OnVariableChange(varname,varvalue)

if (varname=="Marcel.WiFi.SignalStrength") then
marcel_setwifiimg();
elseif (varname=="weatherrefresh") then
NetRemote.SetVariable('weatherrefresh', '0');
NetRemote.ExecuteAction(-1,0,1,"NR.Checkweather");
elseif (varname == "cc.icon") then
iconnumber = tonumber(NetRemote.GetVariable("cc.icon"));
setweatherimg();
elseif (varname == "MP.Zone") then
MYZone = NetRemote.GetVariable("MP.Zone");
if (MYZone == "Main") then Zone = 1 else Zone = 0 end;
NetRemote.SetVariable('Zone', Zone);
end;

end;

If someone could shed somelight on this it would be great.

Thanks

Dan

The only thing I can think of is that SetVariable expects a string for the variable value.

Try changing it to


if (MYZone == "Main") then Zone = "1" else Zone = "0" end;


Note the include of quotes around "1" and "0".

Sorry Again and thanks

Ok Don't worry!

I solved the mistery, in Tonto, when I set up the state, I put




State:Zone

It should have been


STATE:Zone

Thanks for all the help.

That's about 5 miles from me. I think you'll need to set up your ccf to get a weather feed for this part of the country and then give it to me :wink:
