I think, you want to differentiate between meter data update and meter 
widget update, is it? That looks to me very simple and certainly useful. 
See, the data is always there with sensor for retrieving anytime. If meter 
doesn't want to update its gui, it will simply 
ignore the sensor's signal. If it wants to update gui later, it can get the 
value from sensor from function data() manually. What is the problem with 
it? or it may copy the data, which comes with signal, to its private 
variable. Whatever you chose, it is simple. I like the second solution.
Or Have I misunderstood you?
"and then the meter can choose to update it's GUI counterpart "---what does 
it mean? Meter itself would be QWidget hence GUI. so there is no as such any 
counterpart.

It doesn't raise the bar than current theme format IMHO. The people coding 
would be a programmer of certain language. So scripting style should suit to 
them. And layout geometry stuff, it is for multimeter. They can get remain 
away from multimeter in initial stages.
Although Using layouts even for normal meter composition is also tempting. 
But usefulness of layout over "raising the bar" looks to me deciding in 
favour of layout.
