Need help on GUI update
Posted: 03 Dec 2017, 00:37
I have attached a 2.4" touchscreen to a RPI2 and want to have some basic control there.
I have added the volume value to my small display via a new element
However, if the volume is changed by a second client, e.g. running on the PC, the volume value on my RPI-display is not updated.
What do I need to do to update the actual volume value on my RPI-display ?
Can somebody give me a hint, how this is done in Rune UI or point me to some files or code which is responsible to do this ?
